# The Instruments of Trade Policy
Chapter 9 · International Trade · Unit 2 · Revision Notes
### Crux First
- Trade policy includes all measures used by governments to promote or restrict imports and exports.
- The two broad classes are price-related measures and non-price measures.
- Tariffs are price-related measures. They are taxes or duties imposed on imports or exports.
- Non-tariff measures are policy measures other than ordinary customs tariffs that affect trade quantities, prices or both.
- Tariffs are visible barriers. NTMs are often less visible and sometimes operate as hidden barriers.
- Import duties are far more common than export duties, so in practice tariff usually means import duty.
- Specific tariff is a fixed amount per unit. Ad valorem tariff is a fixed percentage of value.
- Anti-dumping duty counters unfairly low foreign prices. Countervailing duty counters foreign export subsidies.
- Import quota restricts quantity directly. Tariff affects quantity indirectly through price.
- SPS and TBT are technical measures. Quotas, licensing, financial controls and procurement rules are non-technical measures.
- Export taxes, export subsidies and voluntary export restraints are export-related measures.
## 1. Meaning of Trade Policy
Trade policy covers all the instruments through which a government influences imports and exports. It includes measures that restrict trade, measures that encourage trade, and the overall position a country takes during trade negotiations. In practical terms, trade policy decides how open or protected a domestic economy will be in relation to the rest of the world.
At one end lies free trade, where buyers and sellers from different countries trade with minimum state interference. At the other end lies protectionism, where the government actively protects domestic producers through tariffs, quotas and other trade restrictions. Between these two lies trade liberalisation, which means reducing trade barriers and opening domestic markets more widely to global goods and services.
## 2. Why Governments Use Trade Policy Instruments
Governments use trade policy because unrestricted trade does not always produce painless outcomes for every domestic industry. Even when open trade improves efficiency and welfare in the long run, some firms and sectors may suffer severe adjustment pressure in the short run. Domestic producers may therefore demand protection against foreign competition, especially when imports become cheaper, larger in volume or allegedly unfair.
Another reason is strategic. Governments may want to raise revenue, protect infant industries, prevent dumping, safeguard employment, ensure food security, respond to subsidies given abroad, or preserve domestic control over sensitive sectors. That is why countries do not rely on a single tool. They use a full set of price measures, quantity restrictions, technical regulations and export-related policies.
## 3. Broad Classification of Trade Policy Instruments
The instruments of trade policy are broadly divided into price-related measures and non-price measures. Price-related measures mainly refer to tariffs, because tariffs work by directly changing the price of imported or exported goods. Non-price measures are called non-tariff measures and they work through rules, procedures, quantity controls, standards, licensing, documentation, restrictions and similar devices.
A third practical area in this unit is export-related measures. These are applied by the exporting country itself and include export taxes, export subsidies, export bans and voluntary export restraints. Together, these instruments shape how much trade takes place, at what price it takes place, and who gains or loses from it.
## 4. Tariffs: Meaning and Purpose
Tariffs, also called customs duties, are taxes imposed at the border on goods moving from one customs territory to another. Different goods usually have different tariff rates, and countries maintain a tariff schedule that lists the duty on each item. Although tariffs may also be imposed on exports, import duties are much more common. For this reason, tariff is usually understood as import duty.
The main purpose of a tariff is to alter relative prices. A tariff raises the domestic price of the imported product while leaving the world price unchanged. Once the imported good becomes costlier inside the country, domestic demand for that foreign good contracts. The two major aims are revenue for the government and protection for domestic industries competing against imports.
## 5. Specific Tariff and Ad Valorem Tariff
A specific tariff is a fixed amount charged per physical unit of the imported good. If the duty is ₹1,000 per bicycle, then every imported bicycle attracts the same tax regardless of its exact price. The weakness of a specific tariff is that its protective strength changes when price changes. If the product price rises sharply, the same fixed duty becomes a smaller percentage of value and therefore gives weaker protection.
An ad valorem tariff is charged as a fixed percentage of the value of the good. If the tariff rate is 20 percent, then the amount of duty rises automatically with the value of the import. This preserves the protective value better than a specific tariff. However, it creates incentive to understate invoice value so as to reduce tax liability.
#### Key Distinction
Specific tariff is linked to quantity or measurement. Ad valorem tariff is linked to value. When prices rise, ad valorem protection stays proportionate, while specific tariff protection weakens.
## 6. Other Important Forms of Tariffs
Mixed tariff uses either an ad valorem rate or a specific duty depending on which gives the desired revenue effect. Compound tariff combines both value-based duty and quantity-based duty. Technical or other tariff is calculated on the basis of the contents or components of the imported good. Tariff rate quota combines quota and tariff, allowing imports up to a certain limit at a lower tariff and charging a much higher tariff beyond that threshold.
Most-Favoured Nation tariff is the tariff a WTO member promises to apply to imports from other WTO members unless there is a preferential trade agreement. Preferential tariff is lower than the MFN rate and is granted to selected countries under reciprocal or unilateral arrangements. Bound tariff is the maximum legal tariff a WTO member has committed not to exceed. Applied tariff is the tariff actually charged, and it may be lower than the bound rate but not higher.
Escalated tariff structure means tariff rates rise as goods move up the value-added chain. Raw materials may face low tariff while processed and manufactured products face higher tariff. Prohibitive tariff is so high that imports virtually stop. Variable tariff is fixed in such a way that the import price is pushed up to the domestic support price.
## 7. Tariff Forms at a Glance
- Tariff Type | Meaning | Quick Recall
- Specific tariff | Fixed amount per unit | ₹ per kg, ₹ per bicycle, ₹ per tonne
- Ad valorem tariff | Fixed percentage of value | 20% of import value
- Mixed tariff | Either ad valorem or specific duty depending on rule | Whichever is higher or lower
- Compound tariff | Specific duty plus ad valorem duty | 5% plus ₹100 per kg
- TRQ | Lower tariff within quota, higher tariff beyond quota | Quota + tariff together
- MFN tariff | Normal WTO member tariff rate | Standard non-preferential rate
- Preferential tariff | Lower tariff for selected country or group | Below MFN rate
- Bound tariff | Maximum committed rate | Legal ceiling
- Applied tariff | Tariff actually charged | May be below bound rate
- Prohibitive tariff | Tariff so high that imports stop | No effective entry
## 8. Trigger-Price Mechanisms and Tariff Responses
Sometimes trade is not merely competitive but distorted. Foreign producers may dump goods abroad at unfairly low prices, or their governments may subsidise exports and artificially strengthen their competitiveness. In such cases, the importing country may respond quickly through tariff-based protection designed to neutralise the distortion. These responses are often described as trigger-price mechanisms.
The basic idea is not ordinary protection but offsetting a foreign unfair advantage. This is why the unit gives special importance to anti-dumping duties and countervailing duties.
## 9. Anti-Dumping Duty
Dumping occurs when a producer sells goods in a foreign market at prices lower than the price charged in its own home market or below full average cost. This creates unfair competition for domestic producers in the importing country. In some cases, dumping may even be used as predatory pricing to drive local firms out and establish monopoly power later.
Anti-dumping duty is an additional import duty imposed to offset this unfair price advantage. It is justified only when the domestic industry suffers serious injury and protection is considered in the national interest. The essential point is that anti-dumping duty is a response to foreign price discrimination and unfairly low pricing.
## 10. Countervailing Duty
Countervailing duty is used when foreign exporters enjoy export subsidies, tax concessions or similar support from their own governments, allowing them to sell at artificially low prices abroad. In such cases, the low price does not arise from genuine comparative advantage alone. It arises from government support that distorts trade.
The importing country imposes countervailing duty to cancel that artificial advantage and restore fair pricing conditions. So the correct distinction is simple: anti-dumping duty answers unfair pricing by firms, while countervailing duty answers subsidy-based advantage provided by governments.
#### Do Not Mix These Two
Anti-dumping duty deals with dumping. Countervailing duty deals with export subsidies and tax concessions granted abroad.
## 11. Effects of Tariffs
Tariffs reduce the volume of imports and create obstacles to international trade. The domestic price of the imported good rises, which hurts consumers because they now pay more and consume less. Consumer surplus falls. At the same time, domestic producers of import substitutes benefit because foreign competition weakens and the domestic selling price rises. Producer surplus goes up, output expands, and employment in the protected industry may also rise.
Government revenue increases by the amount of tariff collected. However, tariffs also distort trade by moving production away from comparative advantage. Efficient foreign production is discouraged and relatively inefficient domestic production is encouraged. So while domestic producers and the government may gain, consumers lose and overall resource allocation becomes less efficient.
## 12. Non-Tariff Measures: Meaning
Non-tariff measures are policy measures other than ordinary customs tariffs that can affect international trade by changing quantities traded, prices or both. They include a wide range of regulations, controls, technical requirements, procedures and restrictions. Unlike tariffs, these are often less visible. That is why they are frequently called hidden or invisible barriers to trade.
It is important not to confuse NTMs with NTBs. Non-tariff barriers are a subset of non-tariff measures. NTMs include all such policy measures, even when they may have a legitimate objective like safety, health or environmental protection. NTBs are those non-tariff measures that operate with discriminatory or protectionist intent in favour of domestic producers.
## 13. Classification of NTMs
Non-tariff measures are broadly classified into technical measures and non-technical measures. Technical measures focus on product characteristics, technical specifications, production processes, food safety, health, environment and quality. Non-technical measures relate more to shipping, customs, finance, quantity controls, competition conditions, procurement rules and similar trade requirements.
They may also be classified as import-related measures, export-related measures and procedural obstacles. Procedural obstacles include delays, certification problems, testing delays, red tape and practical administrative difficulties that make compliance harder even when the rule itself appears legitimate.
## 14. Technical Measures: SPS and TBT
Sanitary and Phytosanitary measures are applied to protect human, animal and plant life from risks arising from additives, contaminants, toxins, pests and disease-causing organisms. They include bans, hygiene rules, production standards and compliance requirements connected with food safety, animal health and plant health.
Technical Barriers to Trade refer to mandatory standards and technical regulations covering product size, shape, design, packaging, marking, labelling, functionality, performance and production methods, except those covered by SPS. The related procedures such as testing, inspection and certification are also part of this framework.
Both SPS and TBT may be justified for legitimate regulatory reasons, but they can also raise compliance costs and reduce the competitiveness of exporters, especially from developing countries.
- Measure | Main Purpose | Examples
- SPS | Protect human, animal and plant life | Pesticide residue limits, ban on diseased poultry imports
- TBT | Technical standards and regulations for products | Labelling, packaging, inspection, certification, quality standards
## 15. Import Quotas
An import quota is a direct restriction on quantity. It fixes the maximum amount of a good that can be imported during a given period, generally a year. Unlike a tariff, which works by raising price and indirectly reducing imports, a quota directly limits the volume of entry. If the quota is set below the free trade level, domestic supply tightens and domestic price rises.
Quotas may be absolute, seasonal, temporary or country-specific. Since the government usually issues licenses to allow imports under the quota, the holders of those licenses may earn quota rents by buying at lower world prices and selling at higher domestic prices. In welfare terms, quotas hurt consumers and benefit domestic producers in much the same way as tariffs, but the government does not automatically earn revenue the way it does under tariffs.
## 16. Other Non-Technical Measures
Price control measures support domestic prices by making imports costlier through additional taxes, charges or minimum import prices. Non-automatic licensing and prohibitions directly limit imports through discretionary licensing or complete bans. Financial measures increase import cost by controlling access to foreign exchange or imposing advance payment conditions.
Measures affecting competition may grant monopoly import rights or special privileges to selected agencies. Government procurement policies may require a specified share of purchases to come from domestic firms. Trade-related investment measures may force local content use or restrict imports in relation to export performance. Distribution restrictions, restrictions on post-sales services, burdensome administrative procedures, and rules of origin can all work as effective trade restraints.
Safeguard measures are temporary import restrictions used when a domestic industry is seriously injured or threatened by a sudden surge in imports. An embargo is the most extreme form of barrier, amounting to a complete ban on import or export of certain goods with specified countries or regions.
## 17. Export-Related Measures
Export-related measures are applied by the exporting country itself. A government may ban exports during shortages so that essential goods remain available for domestic use. It may impose export taxes, which reduce exports, increase domestic supply and lower domestic prices. It may also support exporters through subsidies, duty drawback, concessional finance, grants, loans or price support.
Voluntary Export Restraints are an interesting case. Here the exporting country voluntarily restricts the amount it will export, usually after pressure from the importing country. These arrangements are often political in origin and are used to avoid harsher trade restrictions that might otherwise be imposed by the importing country.

## 20. Final Revision Notes
This unit becomes easy once the tools are grouped correctly. Tariffs are visible price tools. Non-tariff measures are wider and less visible. Technical measures mainly deal with standards, safety and certification. Non-technical measures deal with quotas, licensing, foreign exchange, procurement, distribution and administration. Export-related measures work from the exporter’s side. The hardest confusion points usually arise between specific and ad valorem tariff, anti-dumping duty and countervailing duty, and NTM and NTB.
#### Last-Minute Distinctions
Tariff changes price directly, quota changes quantity directly, anti-dumping duty answers unfair pricing, countervailing duty answers foreign subsidies, SPS protects health and life, TBT regulates product standards, and VER is administered by the exporting country.
