NGK CER-GY12 Ceramic Spark Plug Insulator from China

High-alumina ceramic insulator designed specifically for spark plugs in natural gas-fueled stationary internal combustion engines, such as gas generators and compressors. It provides electrical insulation between the center electrode and the metal shell while withstanding high temperatures and corrosive combustion gases typical of natural gas operation. Classifies under HTS 8547.10.40.00 due to its ceramic composition and dedicated use in production of spark plugs for stationary NG engines.

Import Tips

Verify end-use certification proving insulators are for spark plugs in natural gas stationary engines to avoid reclassification; include manufacturer specs confirming ceramic composition; check for minor metal components that comply with 'minor components' allowance
