Tandom links other provision 9903.53.01 to HTS 4418.99. Its published rate notation is 10%, and its status on 2026-09-26 is expired. A flag is not a shipment-level determination; check origin, product facts, claims, and entry date.
U.S. Customs requires entries to be filed at the 10-digit statistical level — the broader subheading HTS 4418.99 is not directly fileable. Match your product description to the most specific 10-digit line in the list on this page; if multiple lines could apply, the General Rules of Interpretation (GRIs) and chapter notes determine which one governs.
Tandom links 2 potentially relevant AD/CVD order flags to at least one 10-digit line under HTS 4418.99. An HTS link is a screening aid; whether a shipment is covered depends on the order's written product scope and country of origin. Use the linked lookup to review the case materials.
