Carbon-Filled Granular PTFE for Bearings from Japan
Carbon-filled granular PTFE for bearings, with carbon powder at 10-15% to improve wear resistance and conductivity, maintains over 95% PTFE monomer content. As a granular primary form, it is classified under 3904.61.00. The carbon filler does not alter the polymer's primary classification.

Import Tips
• Confirm the carbon filler percentage does not push PTFE monomer below 95% by weight
• Provide a certificate of analysis to CBSA if requested
• Classify as granular primary form, not as an article
