Analysis
HTS 2921.45.90 covers other: other under heading 2921 (amine-function compounds). US Customs collects import statistics for it under 2 ten-digit suffixes, reported in kilograms.
Neighbouring lines carry rates from duty-free to 6.5%, so the exact line matters. The widest gap is with 2921.45.25 (mixtures of 5- and 8-amino-2-naphthalene- sulfonic acid…), at duty-free: a product that belongs there but is entered here, or the reverse, changes the duty by 6.5 percentage points.
The general duty rate is 6.5% of the customs value, which is above most the rates in chapter 29 (83rd percentile of 1050 lines with an ad valorem rate). On a shipment valued at $10,000 that is $650 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 14 others can enter duty-free instead of paying 6.5%. 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.
For statistics it divides in two: 2921.45.90.10 for 2-Amino-1-naphthalenesulfonic acid (Tobias acid) and 2921.45.90.90 for other. Both pay the same duty; the suffix records which kind was imported.
