Ceramic insulators to be used in the production of spark plugs for natural gas-fueled, stationary, internal combustion engines
Analysis
HTS 8547.10.40 covers ceramic insulators to be used in the production of spark plugs for natural gas-fueled, stationary, internal combustion engines under heading 8547 (insulating fittings for electrical machines, appliances or equipment, being fittings…).
Rates on the nearby lines range from duty-free to 4.6%. The costliest confusion would be with 8547.20.00 (insulating fittings of plastics) at duty-free, a difference of 3 points on the customs value.
The general duty rate is 3% of the customs value, which is above most the rates in chapter 85 (78th percentile of 624 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.
The column 2 rate, for countries without normal trade relations, is 60%, 20.0 times the general rate.
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 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.
