NGK CER-GY12 Ceramic Spark Plug Insulator
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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If used in spark plugs for gasoline-fueled engines
Classifies under general ceramic insulating fittings for spark plugs, excluding the specific natural gas stationary engine requirement.
If designed as complete ceramic insulators for general electrical equipment
Shifts to heading 8546 for ceramic insulators not specifically for spark plug production.
If imported as bulk ceramic articles without spark plug designation
Falls under Chapter 69 for ceramic articles if lacking specific electrical insulating function declaration.
