4810.31—Bleached uniformly throughout the mass and of which more than 95 percent by weight of the total fiber content consists of wood fibers obtained by a chemical process and weighing 150 g/m² or less

HTS 4810.31 is a 6-digit subheading of the U.S. Harmonized Tariff Schedule covering Bleached uniformly throughout the mass and of which more than 95 percent by weight of the total fiber content consists of wood fibers obtained by a chemical process and weighing 150 g/m² or less. It belongs to Chapter 48 and rolls up 6 10-digit statistical lines that brokers actually file at entry.

Every 10-digit line under HTS 4810.31 carries a general (Column 1) duty rate of Free. Section 301, Section 232, and AD/CVD overlays may stack on top of this rate at the per-line level — open a specific 10-digit code to see its complete tariff stack.

U.S. Customs requires entries to be filed at the 10-digit statistical level — the broader subheading HTS 4810.31 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.

No active AD/CVD (antidumping or countervailing duty) orders currently flag any line under HTS 4810.31 in Tandom's catalog. Tandom monitors Federal Register notices daily; any new orders will appear here within 24h of publication.
