Analysis
HTS 7902.00.00 covers zinc waste and scrap under heading 7902 (zinc waste and scrap).
Goods classified here enter the United States duty-free at the general (normal trade relations) rate, as do about 9% of the 11 tariff lines in chapter 79. Free here means free of the base duty only: origin-specific Chapter 99 duties such as Section 301 can still be owed.
It is the only US line under subheading 7902.00, so the six-digit code used by every Harmonized System country and the eight-digit US line describe the same goods; a foreign tariff or an exporter's invoice showing 7902.00 points straight here.
Goods from countries without normal trade relations pay the column 2 rate of 11% instead of nothing, so origin decides between free entry and a 11% duty.
Every edition we compared, from Jan 2023 to Oct 2026 (Rev. 22), shows the same general rate of Free.
