Import Tips
• Verify that the glass housing is classified as an insulator, not as a component of a surge arrester (which may fall under heading 8536)
• Provide technical specifications showing the glass shell's insulating function to CBSA
• Check if the surge arrester core is included; if so, the complete article may be classified elsewhere
