Analysis
HTS 7315.81.00 covers other chain: stud link under heading 7315 (chain and parts thereof, of iron or steel).
Neighbouring lines carry rates from duty-free to 3.9%, so the exact line matters. The widest gap is with 7315.89.50 (other: other), at 3.9%: a product that belongs there but is entered here, or the reverse, changes the duty by 3.9 percentage points.
Goods classified here enter the United States duty-free at the general (normal trade relations) rate, as do about 77% of the 250 tariff lines in chapter 73. 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.
Census statistics map these goods to NAICS 332618 (Other Fabricated Wire Product Manufacturing), an industry of 710 US establishments employing 19,060 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.
