Import Tips & Compliance
• Confirm the alloy composition with a mill certificate, as cobalt must predominate by weight over each other metal
• If the alloy contains elements outside Section XV, ensure base metals total at least 50% by weight (Note 5(b))
• Keep records of the intended use for medical devices, as this may affect other regulatory requirements
