Analysis
HTS 8412.80.90 covers other engines and motors: other under heading 8412 (other engines and motors, and 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 27.5% instead of nothing, so origin decides between free entry and a 27.5% duty.
Census statistics map these goods to NAICS 333618 (Other Engine Equipment Manufacturing), an industry of 263 US establishments employing 42,686 people. That concordance is how imports of this line are compared with US output.
All 9 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.
