Analysis
HTS 7905.00.00 covers zinc plates, sheets, strip and foil under heading 7905 (zinc plates, sheets, strip and foil).
The general duty rate is 2.8% of the customs value, which is in the middle of the rates in chapter 79 (32nd percentile of 11 lines with an ad valorem rate). On a shipment valued at $10,000 that is $280 in duty before any Chapter 99 additions or preference claims.
The column 2 rate, for countries without normal trade relations, is 45%, 16.1 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 2.8%. 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.
It is the only US line under subheading 7905.00, 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 7905.00 points straight here.
