Import Tips

• Provide Safety Data Sheets (SDS) and UN certification for hazardous peroxide classification during customs clearance

• Ensure proper stabilization documentation to confirm it meets Chapter 29 note (f) for transport additives

• Avoid misclassification as Chapter 36 explosive by emphasizing chemical initiator function over pyrotechnic use
