Analysis
HTS 8483.30.40 covers flange, take-up, cartridge and hanger units 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 kilograms.
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.
Within this group the rate runs from duty-free to 5.7%. Compared with 8483.40.30 (imported for use with machines for making cellulosic pulp, paper or…), which pays duty-free, a misclassification either way moves the duty by 4.5 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.
For statistics it divides in two: 8483.30.40.40 for ball or roller bearing type and 8483.30.40.80 for other. Both pay the same duty; the suffix records which kind was imported.
