Analysis
HTS 7406.10.00 covers powders of non-lamellar structure under heading 7406 (copper powders and flakes).
Goods from countries without normal trade relations pay the column 2 rate of 49% instead of nothing, so origin decides between free entry and a 49% duty.
The normal trade relations rate here is zero, shared by about 12% of the 89 tariff lines in chapter 74, a useful check when a neighbouring dutiable line is a candidate. Duty-free at the general rate does not rule out additional duties under Chapter 99, such as Section 301 or Section 232 measures, which depend on the country of origin.
The other line in the same group is 7406.20.00 (powders of lamellar structure; flakes, duty-free).
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 concordance is how imports of this line are compared with US output.
Every edition we compared, from Jan 2023 to Oct 2026 (Rev. 22), shows the same general rate of Free.
