Analysis
HTS 7304.90.10 covers of iron or nonalloy steel under heading 7304 (tubes, pipes and hollow profiles, seamless, of iron (other than cast iron) or steel).
There is no general-rate duty on this line, which puts it with roughly 77% of the 250 tariff lines in chapter 73 that are also free. 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.
The other lines in the same group are 7304.90.30 (having a wall thickness of 4 mm or more: of alloy steel, duty-free), 7304.90.50 (of iron or nonalloy steel, duty-free) and 7304.90.70 (having a wall thickness of less than 4 mm: of alloy steel, 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, the industry a domestic producer of these goods reports under.
All 3 neighbouring lines carry the same duty-free rate, so a borderline choice between them changes the statistics reported, not the duty paid.
