Import Tips
• Obtain a certified assay from an accredited laboratory to confirm the silver content and demonstrate that silver predominates over gold and other metals
• The CBSA may require a commercial invoice and packing list detailing the dore's weight and value; ensure these are consistent with the assay
• If the gold content approaches 20%, consult a customs broker to confirm whether the product might be better classified as gold dore under heading 7108
