Triphenyl Phosphate (TPP)
Triphenyl phosphate is an aromatic phosphoric ester used primarily as a flame retardant plasticizer in PVC, resins, and other polymers. It falls under HTS 2919.90.25.00 as an 'other' aromatic plasticizer that is a phosphoric ester, meeting Chapter 29's criteria for chemically defined organic compounds with phosphate functionality.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If used primarily as a flame retardant rather than plasticizer
Non-plasticizer phosphoric esters fall under the general 'other' subheading excluding plasticizers.
If imported as a formulated mixture with solvents or stabilizers
Mixtures not qualifying as Chapter 29 preparations shift to Chapter 38 for chemical preparations.
If classified based on primary ether function over phosphate
Certain phosphate ethers might be interpreted under alcohol/phenol ether headings if not predominantly phosphoric esters.

Import Tips & Compliance
• Verify purity and provide Certificate of Analysis (COA) to confirm classification as a chemically defined compound under Chapter 29
• Ensure REACH/SVHC compliance for EU imports; TPP is listed on candidate lists in some regions
• Label with CAS 115-86-6 and GHS hazard pictograms to avoid customs delays
