Analysis
HTS 8501.53.40 covers exceeding 75 kW but under 149.2 kW under heading 8501 (electric motors and generators (excluding generating sets)). US Customs collects import statistics for it under 2 ten-digit suffixes, reported in number of items.
Neighbouring lines carry rates from 2.8% to 4.2%, so the exact line matters. The widest gap is with 8501.53.60 (149.2 kW or more but not exceeding 150 kW), at 4.2%: a product that belongs there but is entered here, or the reverse, changes the duty by 4.2 percentage points.
For statistics it divides in two: 8501.53.40.40 for for use in civil aircraft and 8501.53.40.80 for other. Both pay the same duty; the suffix records which kind was imported.
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.
