Analysis
HTS 7315.82.30 covers over 10 mm in diameter under heading 7315 (chain and parts thereof, of iron or steel).
The normal trade relations rate here is zero, shared by about 77% of the 250 tariff lines in chapter 73, 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 lines in the same group are 7315.82.10 (not over 10 mm in diameter, duty-free), 7315.82.50 (not over 10 mm in diameter, duty-free) and 7315.82.70 (over 10 mm in diameter, duty-free).
Census statistics map these goods to NAICS 332618 (Other Fabricated Wire Product Manufacturing), an industry of 710 US establishments employing 19,060 people. That concordance is how imports of this line are compared with US output.
Goods from countries without normal trade relations pay the column 2 rate of 10% instead of nothing, so origin decides between free entry and a 10% duty.
