Import Tips
• Provide a detailed chemical analysis and Material Safety Data Sheet (MSDS) to CBSA to support classification as chemical industry waste
• Confirm the sludge is not a separate chemically defined compound, which would fall under Chapter 28 or 29
• Check if the waste requires a permit under the Canadian Environmental Protection Act for import
