Import Quota

What Is Import Quota?

An import quota is a legal limit on the physical quantity of a good that may be imported during a given period. Rather than taxing imports as a tariff does, a quota caps how many units can enter, which restricts supply and pushes up the domestic price of the good. Quotas are a form of protectionism used to shield domestic producers from foreign competition. Access to the limited import allowance is typically controlled through import licenses. Because they work by restricting quantity rather than price, quotas are considered a more direct and often less transparent barrier than tariffs, and international trade rules generally discourage them in favor of tariffs.

Why It Matters

An import quota and a tariff can restrict imports by the same amount, but they differ in a crucial way: with a quota the government collects no tax revenue. Instead, the extra margin between the world price and the higher domestic price goes to whoever holds the import licenses, which may be foreign exporters or domestic importers. This transfer, sometimes called quota rents, is a key reason economists often prefer tariffs to quotas when protection is deemed necessary, since at least a tariff raises public revenue. Quotas also fix the quantity of imports regardless of demand, so shortages and price spikes can be sharper. Understanding the tariff-versus-quota distinction is a staple of AP Macroeconomics trade analysis.
