Import Tips
• Provide assay certificates proving >95% purity to distinguish from industrial grades under 2849.90
• Declare exact phosphine content (<0.1%) as trace impurities affect hazardous classification
• Confirm no organic stabilizers present, as those would shift to heading 2831 per chapter notes
