Import Tips
• CBSA may verify the tin content to ensure it is below 3%, as higher tin would reclassify the product as bronze
• Provide a mill certificate with the chemical composition
• If the sheets are destined for shipbuilding, explore potential duty relief programs, but the tariff classification remains 7409.29.00
