Common questions

What is the duty rate for HTS 7304?
Heading 7304 covers tubes, pipes and hollow profiles, seamless, of iron (other than cast iron) or steel. Duty is assessed at the 10-digit statistical line; the figures here are resolved for 7304.11.00.20, the first line under this heading. Its Column 1 rate is Free. On top of that, the ad valorem total depends on origin: China carries 62.50% and United Kingdom carries 60.00%.
Why does the rate differ by country for the same HTS code?
The Column 1 rate is the same for every origin with normal trade relations. Trade-remedy duties under Sections 232, 301 and 338 are imposed by origin, by product, or by both, so two shipments of the same article from different countries can carry very different totals.
Is this the rate I will actually pay?
It is the rate that applies to this classification and origin on the date shown. The duty owed on a specific entry also depends on the 10-digit statistical suffix, declared content where a duty is content-based, preference eligibility, and any AD/CVD order in scope.
