Analysis
HTS 7304.24.60 covers other, of stainless steel: tubing 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 5 ten-digit suffixes, reported in kilograms.
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.
The other lines in the same group are 7304.24.30 (threaded or coupled, duty-free) and 7304.24.40 (casing: other, duty-free).
The ten-digit suffixes separate having a wall thickness not exceeding…, having a wall thickness exceeding 9.5 mm, having an outside diameter exceeding…, having an outside diameter of 215.9 mm… and having an outside diameter exceeding…. The duty is the same across them; the suffix matters for statistics, licensing and some quotas, and an entry needs all ten digits.
