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 8484?
Heading 8484 covers gaskets and similar joints of metal sheeting combined with other material or of two or more layers of metal; sets or assortments of gaskets and similar joints, dissimilar in composition, put up in pouches, envelopes or similar packings; mechanical seals. Duty is assessed at the 10-digit statistical line; the figures here are resolved for 8484.10.00.00, the first line under this heading. Its Column 1 rate is 2.5%; other lines under 8484 carry different Column 1 rates. On top of that, the ad valorem total depends on origin: China carries 40.00% 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.
