Import Tips
• Ensure the powder is in primary form (e.g
• powder, granules) and not fabricated into articles, as that would change classification
• Keep a technical data sheet showing the PTFE monomer content is 95% or more by weight to support the tariff classification
• Declare the correct 8-digit code 3904.61.00 on your CBSA import documents
