Analysis
HTS 7411.21.50 covers of copper-zinc base alloys (brass): other under heading 7411 (copper tubes and pipes).
The general duty rate is 3% of the customs value, which is above most the rates in chapter 74 (74th percentile of 89 lines with an ad valorem rate). On a shipment valued at $10,000 that is $300 in duty before any Chapter 99 additions or preference claims.
Neighbouring lines carry rates from 1.4% to 3%, so the exact line matters. The widest gap is with 7411.29.10 (other: seamless), at 1.4%: a product that belongs there but is entered here, or the reverse, changes the duty by 1.6 percentage points.
The column 2 rate, for countries without normal trade relations, is 49%, 16.3 times the general rate.
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 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.
