Analysis
HTS 8483.90.30 covers parts of bearing housings and plain shaft bearings: other under heading 8483 (transmission shafts (including camshafts and crankshafts) and cranks; bearing housings…).
The general duty rate is 4.5% of the customs value, which is among the highest the rates in chapter 84 (95th percentile of 823 lines with an ad valorem rate). On a shipment valued at $10,000 that is $450 in duty before any Chapter 99 additions or preference claims.
Neighbouring lines carry rates from 2.5% to 5.5%, so the exact line matters. The widest gap is with 8483.90.50 (parts of gearing, gear boxes and other speed changers), at 2.5%: a product that belongs there but is entered here, or the reverse, changes the duty by 2 percentage points.
Goods that qualify under GSP, the Australia FTA, the Bahrain FTA, the civil aircraft agreement, the Chile FTA, and 13 others can enter duty-free instead of paying 4.5%. It is also eligible under GSP, the developing-country programme, which Congress has to renew; check whether GSP is in force on the entry date.
The column 2 rate, for countries without normal trade relations, is 45%, 10.0 times the general rate.
