Analysis

HTS 3603.30.00 covers safety fuses; detonating cords; percussion or detonating caps; igniters; electric detonators: percussion caps under heading 3603 (safety fuses; detonating cords; percussion or detonating caps; igniters; electric…).

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.

Neighbouring lines carry rates from 0.2% to 3%, so the exact line matters. The widest gap is with 3603.60.00 (electric detonators), at 0.2%: a product that belongs there but is entered here, or the reverse, changes the duty by 4 percentage points.

The general duty rate is 4.2% of the customs value, which is above most the rates in chapter 36 (72nd percentile of 16 lines with an ad valorem rate). On a shipment valued at $10,000 that is $420 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 4.2%. 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 30%, 7.1 times the general rate.
