3804.00—Residual lyes from the manufacture of wood pulp, whether or not concentrated, desugared or chemically treated, including lignin sulfonates, but excluding tall oil of heading 3803

HTS 3804.00 is a 6-digit subheading of the U.S. Harmonized Tariff Schedule covering Residual lyes from the manufacture of wood pulp, whether or not concentrated, desugared or chemically treated, including lignin sulfonates, but excluding tall oil of heading 3803. It belongs to Chapter 38 and rolls up 2 10-digit statistical lines that brokers actually file at entry.

General (Column 1) duty rates for the 10-digit lines under HTS 3804.00 range from Free to 3.7%. 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 3804.00 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.
