HTS 8540.99 is a 6-digit subheading of the U.S. Harmonized Tariff Schedule covering Thermionic, cold cathode or photocathode tubes (for example, vacuum or vapor or gas filled tubes, mercury arc rectifying tubes, cathode-ray tubes, television camera tubes); parts thereof, other. It belongs to Chapter 85 and rolls up 2 10-digit statistical lines that brokers actually file at entry.
Every 10-digit line under HTS 8540.99 carries a general (Column 1) duty rate of Free. Chapter 99 flags and potentially relevant AD/CVD order flags are shown at the per-line level; applicability depends on the shipment facts, written scope, and entry date.
U.S. Customs requires entries to be filed at the 10-digit statistical level — the broader subheading HTS 8540.99 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's current catalog view links no potentially relevant AD/CVD (antidumping or countervailing duty) order flags to lines under HTS 8540.99. Check current Commerce scope materials and Federal Register notices before relying on an HTS-only screen.
