Import Tips
• > Ensure the heater support is clearly non-electrical—any attached wiring, connectors, or insulators could shift classification to Chapter 85
• Keep detailed technical drawings and material specifications to support the classification if requested by CBSA
• Verify whether the part qualifies for preferential tariff treatment under a free trade agreement, as this can reduce the MFN duty rate
