Analysis
HTS 8455.21.00 covers hot or combination hot and cold under heading 8455 (metal-rolling mills and rolls therefor; parts thereof).
There is no general-rate duty on this line, which puts it with roughly 61% of the 823 tariff lines in chapter 84 that are also free. Chapter 99 measures such as Section 301 or 232 can still apply on top, depending on where the goods come from.
Goods from countries without normal trade relations pay the column 2 rate of 30% instead of nothing, so origin decides between free entry and a 30% duty.
Census statistics map these goods to NAICS 333519 (Rolling Mill and Other Metalworking Machinery Manufacturing), an industry of 289 US establishments employing 10,371 people, the industry a domestic producer of these goods reports under.
All 5 neighbouring lines carry the same duty-free rate, so a borderline choice between them changes the statistics reported, not the duty paid.
The general rate of Free has not changed in any edition of the schedule since Jan 2023.
