Import Tips
• Confirm the boards are not treated with preservatives, paint or stain, as treated wood may be classified under a different tariff item
• Keep records of the species (Douglas fir) and dimensions, as the CBSA may request verification
• If the boards are for structural use, ensure they meet Canadian lumber standards and grading rules
