Analysis
HTS 7307.91.10 covers of iron or nonalloy steel under heading 7307 (tube or pipe fittings (for example, couplings, elbows, sleeves), of iron or steel).
The general duty rate is 3.3% of the customs value, which is above most the rates in chapter 73 (85th percentile of 250 lines with an ad valorem rate). On a shipment valued at $10,000 that is $330 in duty before any Chapter 99 additions or preference claims.
Rates on the nearby lines range from 3.2% to 5.5%. The costliest confusion would be with 7307.91.50 (flanges: other) at 5.5%, a difference of 2.2 points on the customs value.
Goods that qualify under GSP, the Australia FTA, the Bahrain FTA, the Chile FTA, the Colombia TPA, and 13 others can enter duty-free instead of paying 3.3%. 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 25%, 7.6 times the general rate.
