Analysis
HTS 2841.80.00 covers tungstates (wolframates) under heading 2841 (salts of oxometallic or peroxometallic acids). US Customs collects import statistics for it under 3 ten-digit suffixes, reported in kilograms and W kg.
The general duty rate is 5.5% of the customs value, which is among the highest the rates in chapter 28 (95th percentile of 274 lines with an ad valorem rate). On a shipment valued at $10,000 that is $550 in duty before any Chapter 99 additions or preference claims.
Rates on the nearby lines range from 1.5% to 5.5%. The costliest confusion would be with 2841.50.10 (potassium dichromate) at 1.5%, a difference of 4 points on the customs value.
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 5.5%. 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 49.5%, 9.0 times the general rate.
