A tariff quota, also called a tariff-rate quota, is a trade rule that allows a limited quantity of specific goods to be imported at a lower or zero duty rate. Once the quota amount is used, additional imports are charged a higher standard tariff. Preferential tariff quotas are usually linked to trade agreements or specific countries, while autonomous tariff quotas may be opened by a government or customs union to support supply needs without being tied to a reciprocal agreement.
Tariff quotas are limits on the quantity of goods that can be imported at a reduced (preferential) duty rate. Once the quota is filled, imports above the quota level pay the full standard duty rate.
Types of Tariff Quotas
- Preferential tariff quotas: linked to FTAs, available to goods from specific countries
- Autonomous tariff quotas (ATQs): EU unilateral quotas for goods not available domestically
- Tariff rate quotas (TRQs): U.S. system allowing a set quantity at a lower rate with higher rates above
Monitor quota fill rates for your product categories. Importing after a quota is exhausted means paying the full duty rate. First-come, first-served allocation makes timing critical.
