Analysis
HTS 7904.00.00 covers zinc bars, rods, profiles and wire under heading 7904 (zinc bars, rods, profiles and wire).
The general duty rate is 4.2% of the customs value, which is among the highest the rates in chapter 79 (96th percentile of 11 lines with an ad valorem rate). On a shipment valued at $10,000 that is $420 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 4.2%. 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.
It is the only US line under subheading 7904.00, so the six-digit code used by every Harmonized System country and the eight-digit US line describe the same goods; a foreign tariff or an exporter's invoice showing 7904.00 points straight here.
The column 2 rate, for countries without normal trade relations, is 25%, 6.0 times the general rate.
