Analysis
HTS 2904.36.00 covers perfluorooctane sulfonyl fluoride under heading 2904 (sulfonated, nitrated or nitrosated derivatives of hydrocarbons, whether or not halogenated).
Within this group the rate runs from duty-free to 5.5%. Compared with 2904.20.20 (derivatives containing only nitro or only nitroso groups…), which pays duty-free, a misclassification either way moves the duty by 3.7 percentage points.
The general duty rate is 3.7% of the customs value, which is in the middle of the rates in chapter 29 (34th percentile of 1050 lines with an ad valorem rate). On a shipment valued at $10,000 that is $370 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 3.7%. 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 25%, 6.8 times the general rate.
