Import Tips & Compliance
• Anhydrous dimethylamine is a compressed gas; ensure your shipping documents classify it as a hazardous material under TDG regulations
• Provide a safety data sheet (SDS) to the CBSA upon request
• Verify whether the gas is in a cylinder that may require a Canadian Registration Number (CRN) for import
