Analysis
HTS 3911.90.25 covers thermoplastic: other under heading 3911 (petroleum resins, coumarone-indene resins, polyterpenes, polysulfides, polysulfones and…).
Within this group the rate runs from duty-free to 6.5%. Compared with 3911.90.70 (chlorinated synthetic rubber), which pays duty-free, a misclassification either way moves the duty by 6.1 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 6.1%. 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 6.1% of the customs value, which is in the middle of the rates in chapter 39 (67th percentile of 236 lines with an ad valorem rate). On a shipment valued at $10,000 that is $610 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 concordance is how imports of this line are compared with US output.
