Analysis
HTS 7210.30.00 covers electrolytically plated or coated with zinc under heading 7210 (flat-rolled products of iron or nonalloy steel, of a width of 600 mm or more, clad…). US Customs collects import statistics for it under 2 ten-digit suffixes, reported in kilograms.
For statistics it divides in two: 7210.30.00.30 for of high-strength steel and 7210.30.00.60 for other. Both pay the same duty; the suffix records which kind was imported.
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.
Goods from countries without normal trade relations pay the column 2 rate of 21.5% instead of nothing, so origin decides between free entry and a 21.5% duty.
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.
