Analysis
HTS 7008.00.00 covers multiple-walled insulating units of glass under heading 7008 (multiple-walled insulating units of glass).
The general duty rate is 3.9% of the customs value, which is in the middle of the rates in chapter 70 (35th percentile of 192 lines with an ad valorem rate). On a shipment valued at $10,000 that is $390 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 3.9%. 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 50%, 12.8 times the general rate.
It is the only US line under subheading 7008.00, 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 7008.00 points straight here.
