Import Tips & Compliance
• Ensure the resin is uncompounded and in primary form (granules) to meet the tariff item requirements
• Provide documentation showing the allyl ester monomers predominate by weight over other monomers
• Be aware that if the resin is used in ion exchange, it may be classified as a functional article elsewhere
