Import Tips & Compliance
• Verify the phosphorus content is within the refined copper limits (≤0.3% for other elements) to avoid classification as a copper alloy
• Provide a certificate of analysis showing phosphorus and copper percentages
• Note that if the phosphorus content exceeds the limit, the product may be classified as a copper alloy under heading 7403.29
