Import Tips
• Ensure the patulin is a pure reference standard, not a mixture or solution that would affect classification
• If it is dissolved in a solvent for laboratory use, check Chapter 29 Note 1(e) for solvent allowances
• Provide the certificate of analysis to the CBSA to support the classification
