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
• Confirm the insulator's primary function is electrical isolation, not mechanical support, to ensure correct classification
• Provide CBSA with tensile strength and dielectric test data
• Check if the insulator is compatible with Canadian utility standards for guy wire insulation
