IELTS vocabulary: International Trade and Tariffs

International trade and tariffs appear constantly in Task 2 under Economy and Globalisation, and the topic rewards precision more than most, since the underlying mechanisms — why a tariff raises prices, why countries specialise, why a trade dispute escalates — are genuinely learnable and genuinely distinct from one another. The vague-vocabulary failure mode is a essay that asserts "free trade benefits everyone" or "tariffs protect local jobs" without explaining the mechanism behind either claim, leaving an examiner unable to tell whether the candidate actually understands the economics or is repeating a memorised opinion. This article works through the vocabulary for the policy tools themselves, their effects, the theoretical debate underneath the whole topic, and the confusions that undercut otherwise strong essays.

Start with the basic policy vocabulary, since "tariff" alone can't carry an entire essay. A "tariff" is a tax imposed specifically on imported goods, typically intended either to raise government revenue or to make foreign goods less price-competitive against domestic alternatives. A "quota" is a related but distinct tool: a direct limit on the quantity of a good that may be imported, regardless of price, rather than a tax that raises its price. A "subsidy" works from the opposite direction — a government payment to domestic producers that lowers their costs, making them more competitive without touching the price of imports at all. "Dumping" is a more specific and more contested term: selling a good in a foreign market below its production cost or below its price at home, often to undercut local competitors, and a common trigger for a tariff dispute. "Trade deficit" and "trade surplus" describe a country importing more than it exports, or the reverse, and are useful shorthand for describing a country's overall trade position without needing to list individual goods.

Vocabulary for the larger policy tools moves an essay beyond individual tariffs to the frameworks countries operate within. A "trade agreement" is a formal deal between countries setting shared terms for trade, often eliminating or reducing tariffs between the signatories specifically. A "free trade zone" is an area, sometimes spanning several countries, within which trade occurs without tariffs or similar barriers. "Protectionism" is the broader ideological stance behind tariffs, quotas, and subsidies collectively: prioritising domestic industry over open competition from abroad, as opposed to "trade liberalisation," the process of reducing such barriers over time. "Economic integration" describes the deepening of trade and economic ties between countries, often through such agreements, and is the term to reach for when an essay discusses countries becoming more interconnected rather than any single deal.

Vocabulary for effects lets an essay trace a policy through to its actual consequences rather than stopping at intention. "Domestic industry protection" names the intended effect of a tariff — shielding local businesses from cheaper foreign competition — while "consumer price increases" names a frequent, less-discussed side effect, since importers facing a tariff commonly pass the added cost on to buyers rather than absorbing it. "Retaliatory tariffs" are tariffs one country imposes specifically in response to another's tariffs, and a "trade war" is the escalating cycle that results when retaliation continues back and forth, with each side raising tariffs further. "Supply chain disruption" is a useful phrase for the effect of tariffs or trade disputes on the network of suppliers and manufacturers a finished product depends on, often located across several countries — a single tariff can ripple through a supply chain in ways a simple "trade is affected" doesn't capture.
