Import Tips
• Maintain documentation showing that dicyandiamide and formaldehyde monomers exceed 95% by weight of the resin
• Ensure the resin is in primary form (powder, granules, or liquid) as required by chapter note 6
• If the resin is blended with other polymers, verify which monomer predominates by weight to confirm classification under this item
