Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the insulator is made of porcelain or composite materials instead of glass.
Insulators of other materials are classified under the residual heading.

The Tariff Assistant works through the GRI rules on your specific product to reach the right tariff item — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Ensure the insulator is designed solely for electrical insulation and not as a structural component of the railway, which could affect classification
• Provide CBSA with engineering drawings or specs showing the glass dielectric function
• Verify compliance with Canadian railway safety standards for overhead electrification
