Import Tips
• Ensure the heat shield is declared as a part of a non-electric industrial furnace, not as a standalone refractory article, to qualify under 8417.90.00
• Keep documentation showing the furnace it is designed for, as CBSA may request proof of its specific use
• Verify if the material composition (e.g
• ceramic) triggers any additional import restrictions
