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
