Analysis
HTS 7315.11.00 covers articulated link chain and parts thereof: roller chain under heading 7315 (chain and parts thereof, of iron or steel). US Customs collects import statistics for it under 4 ten-digit suffixes, reported in kilograms.
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.
Goods from countries without normal trade relations pay the column 2 rate of 40% instead of nothing, so origin decides between free entry and a 40% duty.
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.
