Analysis
HTS 3911.90.91 covers other: other under heading 3911 (petroleum resins, coumarone-indene resins, polyterpenes, polysulfides, polysulfones and…). US Customs collects import statistics for it under 2 ten-digit suffixes, reported in kilograms.
Within this group the rate runs from duty-free to 6.1%. Compared with 3911.90.70 (chlorinated synthetic rubber), which pays duty-free, a misclassification either way moves 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 39 (86th percentile of 236 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 13 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: 3911.90.91.10 for thermoplastic and 3911.90.91.50 for thermosetting. Both pay the same duty; the suffix records which kind was imported.
