Analysis
HTS 7315.20.50 covers over 8 mm in diameter under heading 7315 (chain and parts thereof, of iron or steel).
Within this group the rate runs from duty-free to 3.9%. Compared with 7315.89.50 (other: other), which pays 3.9%, a misclassification either way moves the duty by 3.9 percentage points.
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.
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.
The general rate of Free has not changed in any edition of the schedule since Jan 2023.
