Continuous Cast Copper Billets for Rod Extrusion
Continuous cast refined copper billets, typically 200-300mm in diameter, are unwrought products of refined copper (at least 99.85% copper by weight) used for hot extrusion into copper rods and subsequent wire drawing. They fall under tariff item 7403.13.00 as billets of refined copper, not yet worked after casting.

Import Tips & Compliance
• Ensure the copper content meets the definition of refined copper (≥99.85% by weight) and provide a mill test certificate to CBSA
• Verify the billets are 'unworked' (not machined, drilled, or otherwise processed) to qualify for this tariff item
• Consider duty relief programs if the billets are for further manufacturing in Canada
