Import Tips & Compliance
• > Obtain a certificate of analysis confirming the phosphorus content exceeds 15% by weight
• Ensure the product is not considered a metal alloy of Section XV, as copper phosphide is specifically excluded from that section
• Verify any import restrictions for chemical substances
