Analysis
HTS 8483.50.90 covers other: other under heading 8483 (transmission shafts (including camshafts and crankshafts) and cranks; bearing housings…). 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 5.7%, so the exact line matters. The widest gap is with 8483.50.40 (gray-iron awning or tackle pulleys, not over 6.4 cm in wheel diameter), at 5.7%: a product that belongs there but is entered here, or the reverse, changes the duty by 2.9 percentage points.
The general duty rate is 2.8% of the customs value, which is above most the rates in chapter 84 (73rd percentile of 823 lines with an ad valorem rate). On a shipment valued at $10,000 that is $280 in duty before any Chapter 99 additions or preference claims.
The column 2 rate, for countries without normal trade relations, is 45%, 16.1 times the general rate.
For statistics it divides in two: 8483.50.90.40 for grooved pulleys and 8483.50.90.80 for other. Both pay the same duty; the suffix records which kind was imported.
Goods that qualify under GSP, the Australia FTA, the Automotive Products Trade Act, the Bahrain FTA, the civil aircraft agreement, and 14 others can enter duty-free instead of paying 2.8%. 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.
