Import Tips
• Obtain a certificate of analysis from the supplier confirming copper content is below 0.4% to classify as unalloyed tin
• If the copper content exceeds this limit, the product becomes a tin alloy and may fall under a different heading
• Provide this documentation to the CBSA to avoid delays
