HTS 3907.99 is a 6-digit subheading of the U.S. Harmonized Tariff Schedule covering Polyacetals, other polyethers and epoxide resins, in primary forms; polycarbonates, alkyd resins, polyallyl esters and other polyesters, in primary forms, other. It belongs to Chapter 39 and rolls up 3 10-digit statistical lines that brokers actually file at entry.

General (Column 1) duty rates for the 10-digit lines under HTS 3907.99 range from Free to 6.5%. The exact rate depends on the specific 10-digit statistical line — pick a line below to see its full rate detail.

U.S. Customs requires entries to be filed at the 10-digit statistical level — the broader subheading HTS 3907.99 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.
