TPP is a triaryl phosphoric ester serving as a non-phthalate plasticizer and flame retardant in PVC coatings and engineering plastics. Classified under HTS 2919.90.50.10 as a phosphoric ester plasticizer, it improves processing and flame resistance in applications like wire insulation and textiles. Its aryl structure provides thermal stability over alkyl alternatives.

Import Tips
• Provide technical data sheets confirming plasticizer end-use to distinguish from general phosphoric esters
• Monitor TSCA inventory status and include PMN notifications if modified formulations
• Label with GHS hazard pictograms for skin sensitization potential during customs inspection
