Import Tips

Provide detailed chemical analysis (NMR, MS, purity certificate) to verify identity and confirm classification under 2931.53 as this exact compound

Include Safety Data Sheet (SDS) and end-use statement; phosphonothionates may trigger TSCA notification or pesticide registration if for agrochemical use

Avoid misclassification by ensuring shipment is pure compound, not diluted beyond Chapter 29 note (e) limits for solvents
