Tariff

A tariff is a tax imposed by the government of a country or by a supranational union on imports or exports of goods. Besides being a source of revenue for the government, import duties can also be a form of regulation of foreign trade and policy that taxes foreign products to encourage or safeguard domestic industry. Protective tariffs are among the most widely used instruments of protectionism, along with import quotas and export quotas and other non-tariff barriers to trade.

For other uses, see Tariff (disambiguation).

Tariffs can be fixed (a constant sum per unit of imported goods or a percentage of the price) or variable (the amount varies according to the price). Taxing imports means people are less likely to buy them as they become more expensive. The intention is that they buy local products instead, boosting their country's economy. Tariffs therefore provide an incentive to develop production and replace imports with domestic products. Tariffs are meant to reduce pressure from foreign competition and reduce the trade deficit. They have historically been justified as a means to protect infant industries and to allow import substitution industrialisation. Tariffs may also be used to rectify artificially low prices for certain imported goods, due to 'dumping', export subsidies or currency manipulation.


There is near unanimous consensus among economists that tariffs have a negative effect on economic growth and economic welfare, while free trade and the reduction of trade barriers has a positive effect on economic growth.[1][2][3][4][5][6][7] Although trade liberalisation can sometimes result in large and unequally distributed losses and gains, and can, in the short run, cause significant economic dislocation of workers in import-competing sectors,[8] free trade has advantages of lowering costs of goods and services for both producers and consumers.[9]

Etymology[edit]

The English term tariff derives from the French: tarif, lit.'set price' which is itself a descendant of the Italian: tariffa, lit.'mandated price; schedule of taxes and customs' which derives from Medieval Latin: tariffe, lit.'set price'. This term was introduced to the Latin-speaking world through contact with the Turks and derives from the Ottoman Turkish: تعرفه, romanizedtaʿrife, lit.'list of prices; table of the rates of customs'. This Turkish term is a loanword of the Persian: تعرفه, romanizedtaʿrefe, lit.'set price, receipt'. The Persian term derives from Arabic: تعريف, romanizedtaʿrīf, lit.'notification; description; definition; announcement; assertion; inventory of fees to be paid' which is the verbal noun of Arabic: عرف, romanizedʿarafa, lit.'to know; to can; to recognise; to find out'.[10][11][12][13][14][15]

Price rises from world price Pw to higher tariff price Pt.

Quantity demanded by domestic consumers falls from C1 to C2, a movement along the demand curve due to higher price.

Domestic suppliers are willing to supply Q2 rather than Q1, a movement along the supply curve due to the higher price, so the quantity imported falls from C1−Q1 to C2−Q2.

(the area under the demand curve but above price) shrinks by areas A+B+C+D, as domestic consumers face higher prices and consume lower quantities.

Consumer surplus

(the area above the supply curve but below price) increases by area A, as domestic producers shielded from international competition can sell more of their product at a higher price.

Producer surplus

Government tax revenue is the import quantity (C2 − Q2) times the tariff price (Pw − Pt), shown as area C.

Areas B and D are , surplus formerly captured by consumers that now is lost to all parties.

Arguments favouring tariffs[edit]

Protection of infant industry[edit]

Postulated in the United States by Alexander Hamilton at the end of the 18th century, by Friedrich List in his 1841 book Das nationale System der politischen Oekonomie and by John Stuart Mill, the argument made in favour of this category of tariffs was this: should a country wish to develop a new economic activity on its soil, it would have to temporarily protect it. In their view, it is legitimate to protect certain activities by customs barriers in order to give them time to grow, to reach a sufficient size and to benefit from economies of scale through increased production and productivity gains. This would allow them to become competitive in order to face international competition. Indeed, a company needs to reach a certain production volume to be profitable in order to compensate for its fixed costs. Without protectionism, foreign products – which are already profitable because of the volume of production already carried out on their soil – would arrive in the country in large quantities at a lower price than local production. The recipient country's nascent industry would quickly disappear. A firm already established in an industry is more efficient because it is more adapted and has greater production capacity. New firms therefore suffer losses due to a lack of competitiveness linked to their 'apprenticeship' or catch-up period. By being protected from this external competition, firms can therefore establish themselves on their domestic market. As a result, they benefit from greater freedom of manoeuvre and greater certainty regarding their profitability and future development. The protectionist phase is therefore a learning period that would allow the least developed countries to acquire general and technical know-how in the fields of industrial production in order to become competitive on international market.[61]


According to the economists in favour of protecting industries, free trade would condemn developing countries to being nothing more than exporters of raw materials and importers of manufactured goods. The application of the theory of comparative advantage would lead them to specialise in the production of raw materials and extractive products and prevent them from acquiring an industrial base. Protection of infant industries (e.g., through tariffs on imported products) would therefore be essential for developing countries to industrialise and escape their dependence on the production of raw materials.[19]


Economist Ha-Joon Chang argues that most of today's developed countries have developed through policies that are the opposite of free trade and laissez-faire. According to him, when they were developing countries themselves, almost all of them actively used interventionist trade and industrial policies to promote and protect infant industries. Instead, they would have encouraged their domestic industries through tariffs, subsidies and other measures. In his view, Britain and the United States have not reached the top of the global economic hierarchy by adopting free trade. In fact, these two countries would have been among the greatest users of protectionist measures, including tariffs. As for the East Asian countries, he points out that the longest periods of rapid growth in these countries do not coincide with extended phases of free trade, but rather with phases of industrial protection and promotion. Interventionist trade and industrial policies would have played a crucial role in their economic success. These policies would have been similar to those used by Britain in the 18th century and the United States in the 19th century. He considers that infant industry protection policy has generated much better growth performance in the developing world than free trade policies since the 1980s.[19]


In the second half of the 20th century, Nicholas Kaldor takes up similar arguments to allow the conversion of ageing industries.[62] In this case, the aim was to save an activity threatened with extinction by external competition and to safeguard jobs. Protectionism must enable ageing companies to regain their competitiveness in the medium term and, for activities that are due to disappear, it allows the conversion of these activities and jobs.

Protection against dumping[edit]

States resorting to protectionism invoke unfair competition or dumping practices:

Modern tariff practises[edit]

Russia[edit]

The Russian Federation adopted more protectionist trade measures in 2013 than any other country, making it the world leader in protectionism. It alone introduced 20% of protectionist measures worldwide and one-third of measures in the G20 countries. Russia's protectionist policies include tariff measures, import restrictions, sanitary measures, and direct subsidies to local companies. For example, the government supported several economic sectors such as agriculture, space, automotive, electronics, chemistry, and energy.[79][80]

India[edit]

From 2017, as part of the promotion of its "Make in India" programme[81] to stimulate and protect domestic manufacturing industry and to combat current account deficits, India has introduced tariffs on several electronic products and "non-essential items". This concerns items imported from countries such as China and South Korea. For example, India's national solar energy programme favours domestic producers by requiring the use of Indian-made solar cells.[82][83][84]

Armenia[edit]

Armenia, a country located in Western Asia, established its custom service in 1992 after the dissolution of the Soviet Union. When Armenia became a member of the EAEU, it was given access to the Eurasian Customs Union in 2015; this resulted in mostly tariff-free trade with other members and an increased number of import tariffs from outside of the customs union. Armenia does not currently have export taxes. In addition, it does not declare temporary imports duties and credit on government imports or pursuant to other international assistance imports.[85] Upon joining Eurasian Economic Union in 2015, led by Russians, Armenia applied tariffs on its imports at a rate 0–10 percent. This rate has increased over the years, since in 2009 it was around three percent. Moreover, the tariffs increased significantly on agricultural products rather than on non-agricultural products.[86] Armenia has committed to ultimately adopting the EAEU's uniform tariff schedule as part of its EAEU admission. Until 2022, Armenia was authorised to apply non-EAEU tariff rates, according to Decision No. 113. Some beef, pork, poultry, and dairy products; seed potatoes and peas; olives; fresh and dried fruits; some tea items; cereals, especially wheat and rice; starches, vegetable oils, margarine; some prepared food items, such as infant food; pet food; tobacco; glycerol; and gelatin are included in the list.[87] Membership in the EAEU is forcing Armenia to apply stricter standardisation, sanitary, and phytosanitary requirements in line with EAEU – and, by extension, Russian – standards, regulations, and practices. Armenia has had to surrender control over many aspects of its foreign trade regime in the context of EAEU membership. Tariffs have also increased, granting protection to several domestic industries. Armenia is increasingly beholden to comply with EAEU standards and regulations as post-accession transition periods have, or will soon, end. All Armenian goods circulating in the territory of the EAEU must meet EAEU requirements following the end of relevant transition periods.[88]


The Republic of Armenia became a WTO member in 2003, which resulted in the Most Favored Country (MFC) benefits from the organisation. Currently, the tariffs of 2.7% implemented in Armenia are the lowest in the entire framework. The country is also a member of the World Customs Organization (WCO), resulting in a harmonised system for tariff classification.[89]
