Import Tips & Compliance
• Document the concentration of ethylene oxide in the rinse solution and confirm it is a mixture, not a pure compound
• Provide a safety data sheet (SDS) and any relevant test results to the CBSA
• Verify if the solution is classified as hazardous waste under Canadian law, which may require a permit from Environment and Climate Change Canada
