3910.00.00

Analysis

HTS 3910.00.00 covers silicones in primary forms under heading 3910 (silicones 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.

The general duty rate is 3% of the customs value, which is at the low end of the rates in chapter 39 (16th percentile of 236 lines with an ad valorem rate). On a shipment valued at $10,000 that is $300 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 3%. 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.

It is the only US line under subheading 3910.00, so the six-digit code used by every Harmonized System country and the eight-digit US line describe the same goods; a foreign tariff or an exporter's invoice showing 3910.00 points straight here.

The column 2 rate, for countries without normal trade relations, is 25%, 8.3 times the general rate.
