Import Tips
• Document the product's primary use as a pigment to justify classification under 3206.49.00; if the flame-retardant function is primary, it may be reclassified
• Ensure the product is not a separate chemically defined compound, as chapter note 1(a) excludes such items
• Provide a technical datasheet to CBSA showing the particle size and application in coatings
