Import Tips & Compliance
• Given PFIB's high toxicity, ensure all import documentation, including SDS and transport permits, is ready for CBSA review
• Confirm that any added stabilizers or odoriferous substances are solely for safety, per Chapter 29 Note 1(g)
• Check if additional permits from Health Canada or Environment Canada are required due to its hazardous nature
