Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as general electrical insulators without spark plug features
Loses ignition-specific classification.
If complete spark plug assemblies
Finished spark plugs classified separately.
If ceramic insulators sold without metal contacts
Material composition drives classification without ignition function.
