Import Tips
• Ensure the sheets are 600 mm or more in width and confirm the corrugation pattern meets the tariff item's definition
• Provide documentation on the hot-dip galvanizing process and zinc coating thickness to the CBSA
• If the sheets are pre-cut or punched for culvert assembly, verify they still qualify as flat-rolled products
