Import Tips & Compliance
• Ensure the bromomethane is clearly documented as a chemically defined compound, not a mixture, to support classification under 2903.61.00
• Verify that any stabilizers or impurities do not render the product suitable for a specific use, as per Chapter 29 Note 1
• Confirm the refrigerant is not subject to ozone-depleting substance regulations under the Canadian Environmental Protection Act, which may require permits
