Analysis
HTS 8455.22.00 covers other rolling mills: cold under heading 8455 (metal-rolling mills and rolls therefor; parts thereof).
The normal trade relations rate here is zero, shared by about 61% of the 823 tariff lines in chapter 84, a useful check when a neighbouring dutiable line is a candidate. 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. That concordance is how imports of this line are compared with US output.
All 5 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.
