Import Tips
• Since the salt form is classified with the base compound, ensure the documentation identifies the phenothiazine structure clearly
• Verify that the product is not in a form for retail sale, which would trigger heading 30.04
• Consult the CBSA's controlled substances list to determine if an import permit is needed
