Status unconfirmed. The second statutory four-year review of this action is running. The continuation-request deadlines for the underlying 2018 actions closed on 2026-07-05 and 2026-08-22 and no continuation notice has been published. There is no evidence of termination either, and the duty is almost certainly still collectible; what we cannot do is cite a document saying so.

Common questions

What is the duty rate for HTS 3917?
Heading 3917 covers tubes, pipes and hoses and fittings therefor (for example, joints, elbows, flanges), of plastics. Duty is assessed at the 10-digit statistical line; the figures here are resolved for 3917.10.10.00, the first line under this heading. Its Column 1 rate is 6.5%; other lines under 3917 carry different Column 1 rates. On top of that, the ad valorem total depends on origin: China carries 44.00% 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.
