Analysis
HTS 8483.90.80 covers other: other under heading 8483 (transmission shafts (including camshafts and crankshafts) and cranks; bearing housings…). US Customs collects import statistics for it under 3 ten-digit suffixes, reported in kilograms.
Within this group the rate runs from 2.5% to 5.5%. Compared with 8483.90.70 (parts of articles of subheading 8483.20), which pays 5.5%, a misclassification either way moves the duty by 2.7 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.
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.
