Tariff-Rate Quotas

A tariff-rate quota (TRQ) allows a specified quantity of a product to be imported at a lower customs duty, while imports beyond that quantity face a higher duty. It combines a quantity threshold with two tariff rates, rather than automatically prohibiting imports once the threshold is reached.

How the two tariff rates apply

A TRQ specifies the product covered, the quantity eligible for the lower duty and the period over which that quantity is measured. The applicable duty depends on whether an import qualifies for access within that quota.

• The in-quota tariff applies to eligible imports within the specified quantity; this rate may be zero or a positive duty.
• The out-of-quota tariff applies to imports outside the lower-duty quota and is higher than the in-quota rate.
• Crossing the quota threshold does not retrospectively raise the duty on quantities already admitted at the lower rate.
• The quota normally concerns total eligible imports under the arrangement, not a fresh allowance automatically available to every importer.

An illustrative calculation

Suppose a TRQ permits 1,000 tonnes at a duty of 10%, with imports beyond that quantity attracting 30%. If 1,200 tonnes are imported and the lower-duty entitlement is fully used, 1,000 tonnes attract 10% duty and the remaining 200 tonnes attract 30%.

• For illustrative goods with a uniform customs value of ₹100 per kilogram, the corresponding duties are ₹10 per kilogram within the quota and ₹30 per kilogram outside it.
• The higher rate applies only to the out-of-quota quantity, not to all 1,200 tonnes merely because total imports exceed the threshold.

Quota access and trade implications

Access to the lower rate depends on quota administration, which may involve import licences, allocation to eligible importers or first-come, first-served procedures. Importers must satisfy the relevant eligibility and customs requirements.

• Unlike an absolute import quota, a TRQ does not itself impose a complete ban on imports above the specified quantity.
• A sufficiently high out-of-quota duty can nevertheless discourage additional imports, protecting domestic producers while allowing limited lower-duty access.
• When assessing market access under a trade agreement, both the quota quantity and the two tariff rates matter; a low in-quota rate alone does not establish unrestricted duty-free access.
