Import Tips
• Ensure the ACQ treatment is documented with a certificate from the supplier to prove preservative application
• Verify that the logs are roughly squared and not further processed, as additional machining could change classification
• Declare the species (walnut) and treatment type accurately on the CBSA import documents
