Import Tips

• Verify phosphorus content exceeds 15% with lab certification to confirm classification under 2853 per Chapter Note 7

• Include Material Safety Data Sheets (MSDS) due to phosphide reactivity; ensure DOT-compliant packaging

• Avoid misclassification as copper alloys (7403); chemically defined phosphides stay in Chapter 28
