Analysis
HTS 7306.21.40 covers casing: other under heading 7306 (other tubes, pipes and hollow profiles (for example, open seamed or welded, riveted or…).
Goods classified here enter the United States duty-free at the general (normal trade relations) rate, as do about 77% of the 250 tariff lines in chapter 73. 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 7306.21.30 (threaded or coupled, duty-free) and 7306.21.80 (welded of stainless steel: tubing, 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. That is the industry code a US manufacturer of the same product would normally use.
Goods from countries without normal trade relations pay the column 2 rate of 8.5% instead of nothing, so origin decides between free entry and a 8.5% duty.
All 2 neighbouring lines carry the same duty-free rate, so a borderline choice between them changes the statistics reported, not the duty paid.
