Import Tips

• Verify chemical purity and provide Certificate of Analysis (CoA) to confirm identity as the specific trioxatriphosphinane compound for proper HTS classification

• Include Safety Data Sheet (SDS) detailing non-halogenated nature and phosphorus content to avoid misclassification under halogenated derivatives

• Ensure proper Hazard Class labeling (likely UN 3261 or similar) and comply with TSCA registration for chemical imports into the US
