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
