Import Tips
• Provide chemical purity certificates and CAS number (123-51-3) documentation to verify classification as a separate chemically defined compound
• Ensure proper Hazard Communication labeling for flammable liquids (Class 3) per DOT and OSHA regulations
• Avoid misclassification as mixtures; single isomer products only qualify under this pure compound heading
