Import Tips
• Ensure the BHT stabilizer is present only in quantities necessary for preservation and does not exceed typical industry levels, as excessive amounts could affect classification
• Provide a safety data sheet (SDS) and a certificate of analysis to the CBSA to confirm the product's identity and purity
• Verify if a controlled substances permit is needed, as THF is a monitored chemical in Canada
