Import Tips
• Provide chemical purity certificates and CAS number (108-78-1) documentation to verify classification as pure melamine
• Ensure packaging complies with UN regulations for chemical transport; common pitfall is mislabeling as a finished product
• Declare exact purity percentage; impurities over certain thresholds may shift classification to mixtures
