Import Tips
• Provide chemical purity certificates and CAS number (77-73-6) documentation to verify classification as a separate chemically defined organic compound
• Ensure proper Hazard Communication labeling as it is flammable and requires UN-approved packaging for transport
• Avoid misclassification by confirming it's not mixed with impurities exceeding chapter note tolerances
