Analysis
HTS 7307.11.00 covers of nonmalleable cast iron under heading 7307 (tube or pipe fittings (for example, couplings, elbows, sleeves), of iron or steel). US Customs collects import statistics for it under 3 ten-digit suffixes, reported in kilograms.
Neighbouring lines carry rates from duty-free to 6.2%, so the exact line matters. The widest gap is with 7307.92.30 (sleeves (couplings)), at duty-free: a product that belongs there but is entered here, or the reverse, changes the duty by 4.8 percentage points.
The general duty rate is 4.8% of the customs value, which is above most the rates in chapter 73 (90th percentile of 250 lines with an ad valorem rate). On a shipment valued at $10,000 that is $480 in duty before any Chapter 99 additions or preference claims.
Goods that qualify under GSP, the Australia FTA, the Bahrain FTA, the Chile FTA, the Colombia TPA, and 12 others can enter duty-free instead of paying 4.8%. 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 25%, 5.2 times the general rate.
