Import Tips

• Verify compliance with EPA and TSCA regulations on PFAS chemicals, as PFOSF is subject to import notifications and restrictions

• Provide detailed chemical purity certificates and Safety Data Sheets (SDS) to customs for proper classification

• Avoid misclassification as a finished surfactant; ensure documentation specifies it as the pure sulfonyl fluoride
