Import Tips

• Provide chemical purity certificates and CAS number (84-74-2) documentation to verify classification under Chapter 29 organic compounds

• Ensure proper labeling as a REACH/SVHC restricted substance due to reproductive toxicity concerns in many markets

• Avoid misclassification as a finished plastic product; classify based on chemical identity, not end-use application
