Analysis
HTS 2620.19.30 covers zinc dross and zinc skimmings under heading 2620 (slag, ash and residues (other than from the manufacture of iron or steel), containing…).
Neighbouring lines carry rates from duty-free to 5%, so the exact line matters. The widest gap is with 2620.60.10 (of a kind used only for the extraction of arsenic or the manufacture…), at 5%: a product that belongs there but is entered here, or the reverse, changes the duty by 5 percentage points.
Goods classified here enter the United States duty-free at the general (normal trade relations) rate, as do about 97% of the 39 tariff lines in chapter 26. Free here means free of the base duty only: origin-specific Chapter 99 duties such as Section 301 can still be owed.
Census statistics map these goods to NAICS 331410 (Nonferrous Metal (except Aluminum) Smelting and Refining), an industry of 112 US establishments employing 8,755 people. That is the industry code a US manufacturer of the same product would normally use.
The general rate of Free has not changed in any edition of the schedule since Jan 2023.
