Analysis
HTS 8483.40.80 covers ball or roller screws under heading 8483 (transmission shafts (including camshafts and crankshafts) and cranks; bearing housings…).
Within this group the rate runs from duty-free to 2.5%. 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 3.8 percentage points.
The general duty rate is 3.8% of the customs value, which is above most the rates in chapter 84 (84th percentile of 823 lines with an ad valorem rate). On a shipment valued at $10,000 that is $380 in duty before any Chapter 99 additions or preference claims.
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 3.8%. 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.
The column 2 rate, for countries without normal trade relations, is 45%, 11.8 times the general rate.
