Import Tips
• Ensure the RF window is declared as a part of dielectric loss heat treatment equipment, not as a standalone optical component, to benefit from the parts classification
• Keep technical documentation showing its function in the brazing oven in case CBSA requests verification
• Verify whether the goods qualify for preferential tariff treatment under a free trade agreement to potentially reduce duty
