3902.10.00

Analysis

HTS 3902.10.00 covers polymers of propylene or of other olefins, in primary forms: polypropylene under heading 3902 (polymers of propylene or of other olefins, in primary forms).

This line's footnotes point to one additional provision in Chapter 99: 9903.90.08 (measures on products of Russia). Chapter 99 duties are added on top of the general rate for goods of the countries they name, and they change more often than the rest of the schedule, so check the current CBP guidance before you rely on a total.

Within this group the rate runs from duty-free to 6.5%. Compared with 3902.20.10 (polyisobutylene: elastomeric), 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 12 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.

The column 2 rate, for countries without normal trade relations, is 33.5%, 5.2 times the general rate.
