Live preference check · DCTS country context

Check a DCTS preference without assuming you qualify.

Select the customs origin and commodity code. BorderMath checks the live origin-filtered UK tariff, shows the current DCTS tier and separates the standard tariff from any preferential rate it can resolve.

DCTS preference checker

Country eligibility alone never proves that a shipment qualifies. This checker combines the current country tier with the live commodity measure and leaves rules-of-origin evidence as an explicit condition.

How to read the result

Comprehensive, Enhanced or Standard describes the country's current DCTS preference tier. The actual customs-duty outcome still depends on the commodity, goods graduation, product-specific rules of origin and the evidence needed to support the claim.

A live preferential percentage is therefore shown as “Preference may apply”, not “you qualify”. If the tariff exposes multiple, conditional, quota, weight-based or additional-duty measures, BorderMath sends you to the official record instead of choosing one silently.

Reviewed 7 September 2026. Check the current DCTS preference tiers, the DCTS collection, the 2026–2028 goods-graduation notice and the live UK Trade Tariff.

A DCTS tariff preference is a customs claim, not a generic country discount. Verify origin, product-specific rules, evidence, graduation and any measure conditions before declaration.
