Ad valorem equivalent (AVE)
An AVE is a tariff presented as a percentage of the value of goods cleared through customs. It is the equivalent of a corresponding specific tariff measure based on unit quantities such as weight, number or volume. There are several methodologies for calculating AVEs. The method chosen depends on the intended application of the data. Most important to the process of calculating an AVE is the way the Unit Value of the product is calculated. The unit value is the value of each unit quantity imported of a product. It is based on the total value of imports of that product divided by the quantity of imports.
Ad valorem equivalent (AVE) calculated in MAcMap
In Market Access Map, all non ad valorem (NAV) applied tariffs are converted to ad valorem equivalents (AVEs) according to the unit value (UV) based method. This means that AVEs are calculated by dividing a given NAV tariff by the unit value. For more information on this calculation method, see the methodology.
Ad valorem tariff
An ad valorem tariff is a tariff expressed as a percentage of the value of goods cleared through customs. For example, 15 percent ad valorem tariff means 15 percent of the value of the entered merchandise.
Additional taxes and charges
Additional taxes and charges are additional charges, which are levied on imported goods in addition to customs duties and surcharges and which have no internal equivalents. They include tax on foreign exchange transactions, stamp taxes, import licence fees, consular invoice fees, statistical taxes and tax on transport facilities. See multi-agency classifications of NTMs.
Administrative pricing
Administrative pricing refers to the fixing of import prices by the authorities of the importing country by taking into account the domestic prices of the producer or consumer (e. g. establishing floor and ceiling price limits; reverting to determined international market values). There may be different price fixing methods, such as minimum import prices or prices set according to a reference. See also Price control measures.
Advance import deposit
An advance import deposit is a requirement that the importer should deposit a percentage of the value of the import transaction before receiving the goods (e.g. a payment of 50% of the transaction value is required three months before the expected arrival of the goods to the port of entry). See Finance measures.
Advance payment of customs duties
Advance payment of customs duties is a requirement to pay all or part of the customs duties in advance. However, no interest is paid on these advance payments (e.g. payment of 100% of the estimated customs duty is required three months before the expected arrival of the goods to the port of entry). See multi-agency classifications of NTMs.
Advance payment requirements
Advance payment requirements related to the value of the import transaction and/or related import taxes. These payments are made at the time an application is lodged, or when an import licence is issued. See Finance measures.

Anti-competitive measures
Anti-competitive measures are levied to grant exclusive or special preferences or privileges to one or more limited group of economic operators. They include for example restrictive import channels (e.g. Imports of salt and tobacco are reserved for the respective state trading companies) and compulsory national service (e.g. a requirement that imports must be carried by a national shipping company).
Anti-dumping duties
Anti-dumping duties are levied on certain goods originating from specific trading partner(s) to offset the dumping margin. Duty rates are generally enterprise-specific.
Anti-dumping measure
An anti-dumping measures is a counter measure taken against a dumping action of an exporter. It is considered that dumping takes place when a product is introduced into the commerce of an importing country at less than its normal value, i.e. if the export price of the product exported is less than the comparable price, in the ordinary course of trade, for the like product when destined for consumption in the exporting country. See multi-agency classifications of NTMs.

Countervailing measures are intended to offset any direct or indirect subsidy granted by authorities in the exporting country. These may take the form of extra duty ("countervailing duty") or price undertakings against subsidized imports that are found to be hurting domestic producers. See multi-agency classifications of NTMs.
Custom surcharges
Custom surcharges are an ad hoc tax imposed in addition to customs tariff to raise fiscal revenues or to protect domestic industries  (also referred to as surtax or additional duty).
Customs duty
Custom duties are tariffs levied at the border on goods entering or leaving the country. These charges are specified in the national tariff schedule. 
Customs union
A customs union is a group of countries that adopt free trade (zero tariffs and no other restrictions on trade) on trade among themselves, and that also, on each product, agree to levy the same tariff on imports from outside the group. Equivalent to a free trade agreement plus a common external tariff.
Decreed customs valuation
A decreed customs valuation is a practice to determine the value of goods by a decree for the purpose of imposition of customs duties and other charges. It is applied as a mean to avoid fraud or to protect domestic industry. The decreed value de facto transforms an ad-valorem duty into a specific duty (e. g. the so-called "valeur mercuriale" in Francophone countries). Decreed customs valuation can be appealed according to the WTO rules.
Developed country
The term developed country is used to describe countries that have a high level of development according to certain criteria. Which criteria, and which countries are classified as being developed, is a contentious issue. Economic criteria have tended to dominate discussions. One such criterion is income per capita; countries with high gross domestic product (GDP) per capita would thus be described as developed countries. Another economic criterion is industrialization; countries in which the tertiary and quaternary sectors of industry dominate would thus be described as developed. More recently another measure, the Human Development Index (HDI), which combines an economic measure, national income, with other measures, indices for life expectancy and education has become prominent. This criterion would define developed countries as those with a very high (HDI) rating. However, many anomalies exist when determining "developed" status by whichever measure is used.
Developing country
Developing country is a term generally used to describe a nation with a low level of material well-being. Since no single definition of the term developed country is recognized internationally, the levels of development may vary widely within so-called developing countries.

Effective rate of protection
A measure of the protection provided to an industry by the entire structure of tariffs, taking into account the effects of tariffs on inputs as well as on outputs.
Endogeneity bias in tariff aggregation
Endogeneity bias occures when aggregation of tariffs from the HS 6-digit level up to the HS 4 and HS 2-digit level takes into account import values. In theory, tariffs should be aggregated for imports occurring under a hypothetical situation of free trade. As this is not the case in practice, tariff aggregations, using national imports as weights, cause a distorted perspective on the level of protection since these imports depend on the tariff. That is, a high tariff generates limited imports and therefore the tariff contribution to the overall protection level of the country is reduced. A low tariff produces the reverse effect. So, using national imports as weights leads to an underestimation of the protection level of a country. Market Access Map mitigates this endogeneity bias by weighting the imports of a country by the trade pattern of a Reference Group to which the country belongs. That is, the Reference Group’s imports of the product from the world is used as the weighting.

The GCC was established in 1981. It consists of Bahrain, Kuwait, Oman, Qatar, Saudi Arabia and the United Arab Emirates. These members have established a free trade area covering industrial and agricultural products; but not petroleum products. A customs union was established in 2003.
Harmonized System (HS)
The Harmonized System is an international nomenclature for the classification of products. It allows participating countries to classify traded goods on a common basis for customs purposes. At the international level, the Harmonised System for classifying goods is a six-digit code system. The HS comprises approximately 5000 article/product descriptions that appear as headings and subheadings, arranged in 97 chapters, grouped in 21 sections. The six digits can be broken down into three parts. The first two digits (HS-2) identify the chapter the goods are classified in, e.g. 09 = Coffee, Tea, Maté and Spices. The next two digits (HS-4) identify groupings within that chapter, e.g. 09.02 = Tea, whether or not flavoured. The next two digits (HS-6) are even more specific, e.g. 09.02.10 Green tea (not fermented) in immediate packings of a content not exceeding 3 kg. Up to the HS-6 digit level, different countries classification codes are identical. Beyond this, countries are free to introduce national distinctions for tariffs by adding more digits to make the HS classification of products even more specific. This greater level of specificity is referred as the national tariff line level. For example the United States of America adds another four digits to its exports and imports to classify them in greater depth. The Harmonised System was formally known as the Harmonised Commodity Description and Coding System. It was developed by the World Customs Organization and has been adopted by most trading nations
Hygienic requirements
Hygienic requirements are regulations related to food quality, composition and safety, which are usually based on hygienic and good manufacturing practices, recognized methods of analysis and sampling: The requirements may be applied on the final product or on the production processes.

Intellectual property
Intellectual property are products of the mind, such as inventions, works of art, music and writing.
Internal taxes and charges levied on imports
GATT Article III permits the application of internal taxes and charges on imports so long as they are treated in the same way as domestic production. The general sales tax levied on imports is the equivalent of those internal taxes that are applied to all or most products. There are three types of internal taxes: sales tax, which is an ad valorem tax based on the gross receipt of sales of goods; turnover tax, which is a tax imposed at more than one level of production and distribution and is based on grow receipts, resulting in a cumulation of taxes; value added tax, which is a modified turnover tax based on the net value added instead of on the gross receipts, avoiding the cumulation of taxes and not affecting the price structure and the allocation of resources. The excise tax levied on imports is the equivalent of the excise tax on domestic products, which is an internal tax imposed on selected products, usually of a luxurious or non-essential nature, such as alcoholic beverages and tobacco. This tax is levied separate from, and in addition to, the general sales taxes. Sumptuary taxes, luxury taxes, commodity or consumption taxes all have the same nature as the excise tax. In some countries the consumption tax is similar to a sales tax, being applicable to all products, while in other countries, generally applied taxes are sometimes called excise taxes.
International Monetary Fund (IMF)
The IMF is an international organization of 188 member countries. It was established to promote international monetary cooperation, exchange stability, and orderly exchange arrangements; to foster economic growth and high levels of employment; and to provide temporary financial assistance to countries to help ease balance of payments adjustment.
International Standard Industrial Classification (ISIC)
The International Standard Industrial Classification (ISIC) is a classification structure of economic activities based on a set of internationally agreed concepts, definitions and principles. In ISIC, economic activities, or "industries", are divided in a 4-level structure of mutually exclusive categories. The highest level categories, called sections, are alphabetically coded (i.e. section C for "Manufacturing"). More detailed levels are numbered: two-digit divisions, three-digit groups and four-digit classes. The classification is used to classify statistical units according to the main economic activity they engage in.
International Trade Centre (ITC)
The International Trade Centre (ITC) is a Geneva based technical cooperation agency founded in 1964. ITC's mission is to foster sustainable economic development and contribute to achieving the Millennium Development Goals in developing countries and countries with economies in transition through trade and international business development.
Labelling requirement

Least developed countries (LDC)
The LDCs are a group of 48 countries determined on the basis of the following indicators: Low-income , nutrition, health, education, adult literacy rate, population size, remoteness, merchandise export concentration, share of agriculture, forestry and fisheries, in GDP, share of population living in low elevated costal zones, instability of exports of goods and services, victims of natural disasters, instability of agricultural production.  The Committee for Development Policy (CDP), a subsidiary body of the UN Economic and Social Council, is – inter alia - mandated to review the category of LDCs every 3 years and monitor their progress after graduation from the category. The list of least developed countries therefore varies.
Licence combined with or replaced by special import authorization
Licence combined with or replaced by special import authorization means that a special import authorization required, in addition to or instead of, a licence issued by the main licensing body (usually the Ministry of Trade). This authorization or a requirement for an inscription in a register is required by a specialized authority which is coordinating the sector of the domestic economy related to the concerned products (e. g. A special import authorization from the Ministry of Agriculture is required to import rice). See multi-agency classifications of NTMs .
Licence for specific use
A licence for specified use is a licence granted only for imports of products to be used for pre-specified purpose. Normally granted for use in operations generating anticipated benefit in important domains of the economy (e.g. licence to import steel is granted only if it is used for the construction of a bridge). See multi-agency classifications of NTMs .
Licence linked with local production
A licence linked with local production is a licence granted only for imports of products with linkage to local production (e.g. licence to import coal is granted only if it is used for the production of electricity). See multi-agency classifications of NTMs .
Licence linked with non-official foreign exchange
A licence linked with non-official foreign exchange is a licence granted only if non-official foreign exchange is used for the import payment. See multi-agency classifications of NTMs .
Licence with no specific ex-ante criteria
A licence with no specific ex-ante criteria is a licence issued at the discretion of the issuing authority. It may also be referred to as a discretionary licence (e.g. imports of automobiles are subject to discretionary licence).
Linear reduction formula
Linear reduction formula is a formula for achieving linear tariff cuts. The reduction in tariffs is the size of reduction linearly related to the initial tariff: %Δt = a + bt, where %Δt is the percent reduction in the tariff, t is the initial tariff, and a,b are constants.
Linear tariff cut
A linear tariff cut is a reduction in tariffs with the size of reduction linearly related to the initial tariff. The cut usually takes place by a given percentage, of equal magnitude, across whole classes of products, with or without exceptions for products deemed to be sensitive. Sometimes the linear tariff cut is referred to as horizontal reduction of tariffs, across-the-board reduction of tariffs or equal percentage reduction of tariffs. The linear reduction formula is one of the possible formula approaches. The simplest linear cut, a horizontal reduction, reduces all tariffs by the same percentage.

Local content measures are requirement to use certain minimum levels of locally made component, restricting the level of importing components (e.g. Imports of clothing is allowed only if more than 50% of the materials used are originating from the importing country). See multi-agency classifications of NTMs .
Marking requirements
Marking requirements are measures defining the information for transport and customs that the packaging of goods should carry (e.g. country of origin, weight, special symbols for dangerous substances, etc). See multi-agency classifications of NTMs .
Melanesian Spearhead Group Trade Agreement (MSG Trade Agreement)
The MSG Trade Agreement is a preferential trade arrangement between Melanesian states concluded in 1999. Its membership is composed of 4 states (Fiji, Papua New Guinea, Solomon Islands & Vanuatu) and 1 party (the Kanak and Socialist National Liberation Front of New Caledonia).
Members of the Kimberley Process
The Kimberley Process is a joint governments, industry and civil society initiative to stem the flow of conflict diamonds – rough diamonds used by rebel movements to finance wars against legitimate governments. The trade in these illicit stones has fuelled decades of devastating conflicts in countries such as Angola, Cote d'Ivoire, the Democratic Republic of the Congo and Sierra Leone.
Mercado Común del Sur (MERCOSUR)
MERCOSUR (South American Common Market) is a customs union covering trade in goods except sugar and automobiles. Members are Argentina, Brazil, Paraguay, and Uruguay. Bolivia, Chile, Colombia, Ecuador, Peru and Venezuela have joined Mercosur as Associate members. MERCOSUR objectives include the free transit of all goods, services and the factors of production, and the lifting of non-tariff restrictions.
Mirror data
Mirror trade data are partner country statistics used to approximate non-reported data, also called direct data. Mirror data have shortcomings. For example, it does not cover trade with other non-reporting countries, and inverts the reporting standards by valuing exports in CIF terms and imports in FOB terms.
Mixed tariff
mixed tariff is a rate of duty that is based on a conditional choice between an ad valorem duty and a specific duty, subject to an upper (ceiling) and/or a lower (floor) limit (e.g.: 30% or £2 per kg, whatever is the highest).
Montreal Protocol
Agreed in 1987 following the discovery of the “ozone hole”, the Montreal Protocol protects the ozone layer from damage caused by certain industrial chemicals known as ozone-depleting substances (ODS). 
Most favoured nation tariffs (MFN tariffs)
MFN tariffs are the tariffs applied by WTO members to goods imported from other WTO member countries. In the case of WTO non members, the application of these rates may be a requirement of a bilateral trade agreement. Article 1 of the General Agreement on Tariffs and Trade (GATT) lays down the principle of Most Favoured Nation treatment (MFN). The MFN clause states that a member of the GATT must treat all GATT members equally. The WTO is the successor of the GATT and the WTO’s rules derive from the outcome of the 1986-94 Uruguay Round negotiations which included a major revision of the original General Agreement on Tariffs and Trade (GATT). So the application of the MFN principle is required of WTO members. Every time a WTO member improves the benefits that it gives to one trading partner, it has to give the same "best" treatment to all other WTO members, so that they remain equal. Countries are to grant equal treatment - not more favourable or discriminatory - to goods and services from all WTO members. The MFN principle applies to all tariffs - whether or not they have been subject to negotiations between GATT members - as well as to all policy measures affecting imports or exports.
However, there are some exceptions to the MFN principle.
GATT article XXIV allows countries that are seeking regional integration to reduce their tariffs below the MFN rate if the following conditions are met: tariff and other barriers to trade among the contractors of the agreement must be eliminated substantially for all products within a reasonable period of time; regional integration must not worsen the market access conditions granted to other WTO members previous to the enforcement of the agreement.
Derogations to the MFN treatment are also conceded to developing countries, in respect of specific conditions, by the signatories of the GATT (i.e. Contracting Parties) Decision of 25 June 1971, relating to the establishment of "Generalized, non-reciprocal and non-discriminatory preferences beneficial to the developing countries" (BISD 18S/24) and the Decision of 28 November 1979 on "Differential and More Favourable Treatment, Reciprocity, and Fuller Participation of Developing Countries" (L/4903), also known as the "Enabling Clause”.
Another exception derives from the Marrakesh Agreement (establishing the World Trade Organization) article XIII which, under specific conditions, allows for the case of non-application of MFN treatment between original Members of the WTO, which were contracting parties to GATT 1947, and countries that made their accession later (article XII).
Most favoured nation treatment (MFN treatment)
MFN treatment is the rule, usually established through a trade agreement, that a country gives each of the trading partners with which it has concluded relevant trade agreements the best treatment it gives to any of them.
Multi-agency classification of NTMs
The multi-agency NTM classification was prepared by a group of technical experts from eight international organizations – FAO, IMF, ITC, OECD, UNCTAD, UNIDO, the World Bank and the WTO in 2008, with subsequent revisions in 2009 and 2012. This classification first categorizes NTMs into two broad categories, technical and non-technical measures, which are further divided into 16 alphabetically coded chapters. Technical measures (Chapters A and B) refer to product-specific properties such as characteristics, technical specifications and production process of a product. It also includes conformity assessment methods, which affirm the compliance of a product to a given requirement. These technical regulations are generally aimed at ensuring quality and food safety, environmental protection and national security, and at protecting animal and plant health. Non-technical measures (Chapters C to O) do not refer to product-specific properties but to trade requirements, such as shipping requirements, custom formalities, trade rules, taxation policies, etc. Chapters are subdivided into single digit branches e.g. "A3: Labelling, marking and packaging requirements". Finally, to further increase the level of detail, these branches are divided into leafs by adding another 2 digits to the classification code e.g. "A310: Labelling requirements".
Multi-column tariff
multi-column tariff is a tariff schedule that discriminates between the various trading partners. Tariff rates in the first column might be reserved for countries receiving only the general tariff rate and the second column may display the favoured nation (MFN) treatment. The third and additional columns would contain the rates applicable to various preferential trade arrangements, such as free-trade area partners or those given to developing countries under the Generalized System of Preferences (GSP).
Multilateral trade agreements
Multilateral agreements are intergovernmental agreements aimed at expanding and liberalising international trade under non-discriminatory, predictable and transparent conditions set out in an array of rights and obligations.
Multilateral trading system
The multilateral trading system is a non discriminatory arrangement for international trade which came into existence with the GATT in 1947 and which is now represented by the WTO system.
Multiple exchange rates
Multiple exchange rates are varying exchange rates for imports, depending on the product category. Usually, the official rate is reserved for essential commodities while the other goods must be paid at commercial rates or occasionally by buying foreign exchange through auctions (e.g. only the payment for infant food and staple food imports may be made at the official exchange rate). See multi-agency classifications of NTMs.
National tariff line (NTL)
National Tariff Line codes refer to the classification codes, applied to merchandise goods by individual countries, that are longer than the HS six digit level. Countries are free to introduce national distinctions for tariffs and many other purposes. The national tariff line codes are based on the HS system but are longer than six digits. For example, the six digit HS code 010120 refers to Asses, mules and hinnies, live, where as the US National Tariff line code 010120.10 refers to live purebred breeding asses, 010120.20 refers to live asses other than purebred breeding asses and 010120.30 refers to mules and hinnies imported for immediate slaughter.
Non-ad valorem tariffs (NAV)
A non ad-valorem tariff is a tariff that is not expressed as a percentage of the price or value. This can refert to a specific, compound, mixed or some other form of a tariff. These other forms can be determined by complex technical factors. The duty can be based on the percentage content of the agricultural component (e. g. sugar, milk, alcohol content, etc.) or its strength (e.g. the degree of sweetness).
Non-automatic licensing
A non-automatic licence is an import licence which is not granted automatically. The licence may either be issued on a discretionary basis or may require specific criteria to be met before it is granted. See multi-agency classifications of NTMs .
Non-tariff barriers (NTB)
NTBs are measures negatively affecting international trade.
Non-tariff measures (NTMs)
Non-tariff measures include market requirements, taxes and procedures that countries apply to products that are imported or exported. These can include for example health regulations on food quality, rules about packaging, minimum safety standards for manufactured products, internal taxes that are levied in addition to import duties and many more. Market Access Map provides information on a wide range of regulations applied by countries as well as links, where available, to the responsible institutions and / or the regulations themselves to help users further research the product and process-related compliance issues involved in exporting or importing. See multi-agency classifications of NTMs .

Organisation for Economic Co-operation and Development (OECD)
The OECD was established in 1961 as the successor to the Organisation for European Economic Cooperation (OEEC). It's members account for more than 59% of global GDP and three-quarters of world trade. The OECD currently has 34 member countries.
Organisation of Islamic Cooperation (OIC)
The OIC (formerly Organization of the Islamic Conference) is the second largest intergovernmental organization after the United Nations, with a membership of 57 states spread over four continents. The Organization was established in Rabat, Kingdom of Morocco on 25 September 1969.
Outside quota tariff rate (OQTR)
A OQTR is the tariff rate applicable to products imported in excess of a tariff quota volume. This rate is meant to discourage imports above the quota limit. It is usually much higher than the one applied to imports within the quota.
Overseas Countries and Territories (OCT)
There are 21 so-called overseas countries and Territories (OCTs) which depend constitutionally on four of the European Union (EU) Member States: Denmark, France, the Netherlands, and the United Kingdom. OCT nationals are European citizens. However, these countries do not form part of EU territory. Accordingly, they are not directly subject to EU law, but they benefit from associate status conferred on them by the Treaty of Lisbon. The aim of this association is principally to contribute to their economic and social development.
Pacific Islands Forum

Since 1971 it has provided member nations with the opportunity to express their joint political views and to cooperate in areas of political and economic concern. 
Packaging requirements
Packaging requirements are measures regulating the mode in which goods must or cannot be packed, or defining the packaging materials to be used (e.g. Restricted use of PVC films for food packaging). See multi-agency classifications of NTMs.
Para-tariff measures
Para-tariff measures are measures that increase the cost of imports in a similar manner to tariffs. These measures include customs surcharges, additional taxes and charges (e.g. tax on foreign exchange transactions, stamp tax), service charges, internal taxes and charges levied on imports (e.g. general sales taxes, excise taxes) and decreed customs valuation. See multi-agency classifications of NTMs.
Preferences

Pre-shipment inspection
Pre-shipment inspection are a physical inspection of goods before they are shipped in the country of export, which establishes the exact nature of the goods. The inspection assures that the goods are in accordance with the accompanying documents that specify their customs tariff code, quality, quantity and price (e. g. a pre-shipment inspection of textile imports by a third party for verification of colours and types of materials). See multi-agency classifications of NTMs.
Price control measures
Price control measures are measures implemented to control the prices of imported articles in order to support the domestic price of certain products when the import price of these goods are lower, establish the domestic price of certain products because of price fluctuation in domestic markets or price instability in a foreign market and counteract the damage resulting from the occurrence of "unfair" foreign trade practices. See <a href=" http://www.intracen.org/itc/market-info-tools/non-tariff-measures/understanding-ntms/" target="_blank">multi-agency classifications of NTMs</a>.
Private standards
The term private standards as used by WTO, FAO or UNIDO relates to standards developed by non-governmental entities. These include individual firms, industry organisations, and non-governmental organisations, among others. As such, compliance to these standards is not legally required by national governments or multilateral regulations as opposed to public standards. Private standards vary widely in their objectives and scope.
Prohibition of foreign exchange allocation
Prohibition of foreign exchange allocation means that no official foreign exchange allocations available to pay for imports (e.g. foreign exchange is not allocated for imports of luxury products such as motor vehicles, TV sets, jewelleries). See <a href=" http://www.intracen.org/itc/market-info-tools/non-tariff-measures/understanding-ntms/" target="_blank">multi-agency classifications of NTMs</a>.
Prohibitions
A non-tariff measure used to control imports. There are total prohibitions (e. g. Import of "motor vehicle with cylinder under 1500cc" is not allowed to encourage domestic production), Suspensions of issuance of licences (e.g. Issuance of licence to import "motor vehicle with cylinder under 1500cc" is suspended until further notice.), seasonal prohibitions (e.g. Import of strawberries is not allowed from March to June each year.), temporary prohibitions (e.g. Import of certain fish is prohibited with immediate effect until the end of the current season), prohibitions of products infringing patents or intellectual property rights (e.g. Import of imitation brand handbags is prohibited) and prohibitions for non-economic reasons (e.g. imports of books and magazines displaying pornographic pictures are prohibited). See <a href=" http://www.intracen.org/itc/market-info-tools/non-tariff-measures/understanding-ntms/" target="_blank">multi-agency classifications of NTMs</a>.

Quantity control measures
Quantity control measures are aimed at restraining the quantity of goods that can be imported, regardless of whether they come from different sources or one specific supplier. These measures can take the form of restrictive licensing, fixing of a predetermined quota, or through prohibitions. See multi-agency classifications of NTMs.
Quarantine requirement
A quarantine requirement is a requirement to detain or isolate animals, plants or their products on arrival at a port or place for a given period in order to prevent the spread of infectious or contagious disease, or contamination (e.g. quarantine requirements for live dogs; plant quarantine measures to terminate or restrict the spread of harmful organisms and mitigate the adverse impacts thereof). See multi-agency classifications of NTMs.
Quotas
Quotas are explicit limits on the quantity of a good that can be imported or exported during a specified time period. Such limits are usually measured by physical quantity but sometimes by value. A quota may be applied on a selective basis, with varying limits set according to the country of origin or destination or bilaterally (to a single trading partner), or on a global basis (to all countries) that specifies only the total limit and thus tends to benefit more efficient suppliers. Quotas are frequently administered through a system of licensing. Non-automatic licensing usually the means for administering a quota. GATT Article XI prohibits the use of quantitative restrictions, subject to specific exceptions. For example Article XIX permits quotas to safeguard certain industries from damage by rapidly rising imports. See multi-agency classifications of NTMs.
Quotas linked with the purchase of local goods
Quotas linked with purchase of local goods are quotas defined as a percentage of the value of goods purchased locally (i.e. in the importing country) by the exporter (e.g. imports of refined oil in volume are limited to the volume of crude petroleum purchased locally). See multi-agency classifications of NTMs.
Refundable deposits for sensitive product categories
Refundable deposits for sensitive product categories are a requirement to pay a certain deposit which is refunded when the used product or its container is returned to a collection system (e.g. $100 deposit is required for each refrigerator, which will be refunded when brought in for recycling after use). See multi-agency classifications of NTMs.
Regional trade agreement (RTA)
Regional trade agreements (RTAs) are reciprocal trade agreements between two or more partners.
Regulations concerning terms of payment for imports
Regulations concerning terms of payment for imports are regulations related to conditions of payment for imports and for obtaining and using credit to finance imports (e.g. no more than 50% of the transaction value can be paid in advance of the arrival of goods to the port of entry).
Rules of Origin (ROO)
Laws, regulations and administrative procedures which determine a product’s country of origin. A decision by a customs authority on origin can determine whether a shipment falls within a quota limitation, qualifies for a tariff preference or is affected by an anti-dumping duty. These rules can vary from country to country.

See multi-agency classifications of NTMs.
Sanitary and Phytosanitary measures (SPS)
Sanitary and Phytosanitary measures are laws, decrees, regulations, requirements, standards and procedures to protect human, animal or plant life or health from certain risks such as the establishment or spread of pests, diseases, disease-carrying organisms or disease-causing organisms, risks from additives, contaminants, toxins, disease causing organisms in foods, beverages or feedstuffs. See multi-agency classifications of NTMs.
Scenario

Seasonal duties are duties applicable at certain times of the year, usually in connection with agricultural products. For example, imports of "Fresh perry pears, in bulk" from 1 August to 31 December may enter free of duty, while in other months, positive duties (seasonal duty) are applied. See multi-agency classifications of NTMs.
Seasonal quotas
Seasonal quotas are quotas established for a given period of the year, usually set for certain agricultural goods when domestic harvest is in abundance (e.g. quota for import of strawberries is established for imports from March to June each year). See multi-agency classifications of NTMs.

Standard International Trade Classification (SITC)
SITC is a classification intended to categorize trade statistics into large economic classes of commodities, maintained by the United Nations.
Swiss formula
The Swiss formular is a formula devised during the Tokyo Round for reducing tariffs in a manner that would harmonize them. The formula is tnew=(toldM)/(told+M), where the t's are the new and old tariffs, in percent, and M is a coefficient which also turns out to equal the maximum possible new tariff rate.
Tariff binding
Tariff escalation
In the case of tariff escalation, import duties are higher on semi-processed products than on raw materials, and higher still on finished products. This practice protects domestic processing industries and discourages the development of processing activity in the countries where raw materials originate.
Tariff peak
tariff peak is a relatively high tariff, usually on “sensitive” products, amidst generally low tariff levels. For industrialized countries, tariffs of 15% and above are generally recognized as “tariff peaks”.
Tariff rate quota
A tariff rate quota is a combination of an import tariff and an import quota in which imports below a specified quantity enter at a low (or zero) tariff and imports above that quantity enter at a higher tariff. A tariff quota has thus two parts, the Inside Quota Tariff Rate and the Outside Quota Tariff Rate.
Tariff reduction simulation
Tariff reduction simulation module available in Market Access Map allows users to apply various tariff reduction formulas to produce tariff schedules before and after a tariff reduction. This back to back comparison of pre and post liberalisation rates helps to prepare for trade negotiations and evaluate the impact of each formula on the final tariff schedule.
Tariff regime
A tariff regime is a set of tariff rates covering all products for a particular importing country, exporting country, preferential status (specific preferences or MFN/General rates) and time period.
Tariff schedule
