Rates on the nearby lines range from duty-free to 3.9%. The costliest confusion would be with 7315.89.30 (over 8 mm in diameter) at duty-free, a difference of 2.9 points on the customs value.
The general duty rate is 2.9% of the customs value, which is above most the rates in chapter 73 (80th percentile of 250 lines with an ad valorem rate). On a shipment valued at $10,000 that is $290 in duty before any Chapter 99 additions or preference claims.
The column 2 rate, for countries without normal trade relations, is 45%, 15.5 times the general rate.
Goods that qualify under GSP, the Australia FTA, the Automotive Products Trade Act, the Bahrain FTA, the Chile FTA, and 13 others can enter duty-free instead of paying 2.9%. 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.
