Import Tips
• Submit NMR or GC-MS spectra verifying the diethylene glycol monomethyl ether structure to confirm Chapter 29 classification
• Declare flash point (96°C) and proper shipping name 'Glycol ether' for DOT compliance during import
• Avoid misclassification by providing evidence it's not a Chapter 38 reactive diluent or paint additive
