Analysis
HTS 8503.00.45 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).
Within this group the rate runs from duty-free to 6.5%. Compared with 8503.00.75 (for motors of under 18.65 W), which pays 6.5%, a misclassification either way moves 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.
The normal trade relations rate here is zero, shared by about 58% of the 624 tariff lines in chapter 85, a useful check when a neighbouring dutiable line is a candidate. 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 concordance is how imports of this line are compared with US output.
