7305.90.50

Analysis

HTS 7305.90.50 covers other: of alloy steel under heading 7305 (other tubes and pipes (for example, welded, riveted or similarly closed), having circular…).

The normal trade relations rate here is zero, shared by about 77% of the 250 tariff lines in chapter 73, a useful check when a neighbouring dutiable line is a candidate. 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 331110 (Iron and Steel Mills and Ferroalloy Manufacturing), an industry of 359 US establishments employing 78,532 people. That concordance is how imports of this line are compared with US output.

Goods from countries without normal trade relations pay the column 2 rate of 10% instead of nothing, so origin decides between free entry and a 10% duty.

All 16 neighbouring lines carry the same duty-free rate, so a borderline choice between them changes the statistics reported, not the duty paid.
