What is the duty rate for HTS 8410?

Heading 8410 covers hydraulic turbines, water wheels and regulators therefor; parts thereof. Duty is assessed at the 10-digit statistical line; the figures here are resolved for 8410.11.00.00, the first line under this heading. Its Column 1 rate is 3.8%. On top of that, the ad valorem total depends on origin: Canada carries 63.80% and Italy carries 10.00%.

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.
