Analysis
HTS 7308.30.10 covers of stainless steel under heading 7308 (structures (excluding prefabricated buildings of heading 9406) and parts of structures…).
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.
Census statistics map these goods to NAICS 332321 (Metal Window and Door Manufacturing), an industry of 1,027 US establishments employing 59,920 people, the industry a domestic producer of these goods reports under.
All 8 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.
