Import Tips
• Obtain proper HAZMAT certification and UN-approved packaging as PCl3 is corrosive and reacts violently with water
• Include Safety Data Sheet (SDS) and purity certificate in documentation to verify classification under Chapter 28
• Avoid misclassification as pesticide intermediate; confirm it's not organo-inorganic per Chapter Note 2(b)
