Analysis
HTS 7304.59.80 covers other: other under heading 7304 (tubes, pipes and hollow profiles, seamless, of iron (other than cast iron) or steel). US Customs collects import statistics for it under 14 ten-digit suffixes, reported in kilograms.
The ten-digit suffixes separate having an outside diameter less than…, having a wall thickness less than 6.4 mm, having a wall thickness of 6.4 mm or…, having a wall thickness exceeding 12.7…, having a wall thickness less than 12.7… and having a wall thickness of 12.7 mm or… and 8 more. The duty is the same across them; the suffix matters for statistics, licensing and some quotas, and an entry needs all ten digits.
Goods from countries without normal trade relations pay the column 2 rate of 35% instead of nothing, so origin decides between free entry and a 35% duty.
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.
