Import Tips

Verify chemical purity and provide Certificate of Analysis (CoA) to confirm it matches the exact specification of diethylammonium perfluorooctane sulfonate

Include Safety Data Sheet (SDS) and ensure compliance with TSCA regulations due to PFAS restrictions

Avoid misclassification as a mixture; ship as pure compound to prevent reclassification under Chapter 38
