Analysis
HTS 3911.90.45 covers thermosetting: other under heading 3911 (petroleum resins, coumarone-indene resins, polyterpenes, polysulfides, polysulfones and…).
Neighbouring lines carry rates from duty-free to 6.5%, so the exact line matters. The widest gap is with 3911.90.70 (chlorinated synthetic rubber), at duty-free: a product that belongs there but is entered here, or the reverse, changes the duty by 5.8 percentage points.
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 5.8%. 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 general duty rate is 5.8% of the customs value, which is in the middle of the rates in chapter 39 (61st percentile of 236 lines with an ad valorem rate). On a shipment valued at $10,000 that is $580 in duty before any Chapter 99 additions or preference claims.
Census statistics map these goods to NAICS 325211 (Plastics Material and Resin Manufacturing), an industry of 1,285 US establishments employing 88,827 people. That is the industry code a US manufacturer of the same product would normally use.
