Analysis
HTS 8503.00.90 covers for generators suitable for use on aircraft under heading 8503 (parts suitable for use solely or principally with the machines of heading 8501 or 8502).
Neighbouring lines carry rates from duty-free to 6.5%, so the exact line matters. The widest gap is with 8503.00.75 (for motors of under 18.65 W), at 6.5%: a product that belongs there but is entered here, or the reverse, changes the duty by 6.5 percentage points.
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.
Goods classified here enter the United States duty-free at the general (normal trade relations) rate, as do about 58% of the 624 tariff lines in chapter 85. Free here means free of the base duty only: origin-specific Chapter 99 duties such as Section 301 can still be owed.
Census statistics map these goods to NAICS 335312 (Motor and Generator Manufacturing), an industry of 398 US establishments employing 29,856 people. That is the industry code a US manufacturer of the same product would normally use.
