Import Tips
• Ensure the insulators are described as ceramic electrical insulators, not as parts of spark plugs, which are classified under heading 85.11
• Provide specifications on dielectric strength and material composition to support the classification
• If imported with metal electrodes, confirm whether they are complete spark plugs or just insulators
