Analysis
HTS 7213.91.45 covers containing by weight 0.6 percent or more of carbon under heading 7213 (bars and rods, hot-rolled, in irregularly wound coils, of iron or nonalloy steel).
The normal trade relations rate here is zero, shared by about 92% of the 262 tariff lines in chapter 72, a useful check when a neighbouring dutiable line is a candidate. Chapter 99 measures such as Section 301 or 232 can still apply on top, depending on where the goods come from.
The other lines in the same group are 7213.91.30 (not tempered, not treated and not partly manufactured, duty-free) and 7213.91.60 (other: other, duty-free).
Census statistics map these goods to NAICS 331110 (Iron and Steel Mills and Ferroalloy Manufacturing), an industry of 359 US establishments employing 78,532 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 5.5% instead of nothing, so origin decides between free entry and a 5.5% duty.
All 2 neighbouring lines carry the same duty-free rate, so a borderline choice between them changes the statistics reported, not the duty paid.
