Analysis
HTS 7210.70.30 covers not coated or plated with metal and not clad under heading 7210 (flat-rolled products of iron or nonalloy steel, of a width of 600 mm or more, clad…).
Goods classified here enter the United States duty-free at the general (normal trade relations) rate, as do about 92% of the 262 tariff lines in chapter 72. Chapter 99 measures such as Section 301 or 232 can still apply on top, depending on where the goods come from.
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 is the industry code a US manufacturer of the same product would normally use.
All 13 neighbouring lines carry the same duty-free rate, so a borderline choice between them changes the statistics reported, not the duty paid.
Every edition we compared, from Jan 2023 to Oct 2026 (Rev. 22), shows the same general rate of Free.
