Import Tips
• Verify chemical purity and provide Certificate of Analysis (CoA) to confirm identity as bis(1-methylpentyl) methylphosphonate per HTS specifications
• Include Safety Data Sheet (SDS) detailing non-halogenated nature and phosphorus-carbon bonding to avoid misclassification
• Check REACH or TSCA compliance for phosphorus compounds; improper documentation can lead to CBP holds
