Triphenyl phosphate serves as a flame retardant and plasticizer in PVC, resins, and nail polishes. Classified under HTS 2919.90.50 as a 'other' phosphoric ester, it matches the heading for non-substituted phosphate triesters. Its aryl phosphate structure distinguishes it from alkyl phosphates or derivatives.

Import Tips
• Submit structural formula and molecular weight data to confirm classification as unsubstituted phosphoric ester
• Label with REACH compliance if from EU; avoid pitfalls by distinguishing from tris(2-chloroethyl) phosphate (TCEP) in 2919.90.20
• For plasticizer grades, specify non-coloring/non-odor additions per Chapter 29 note (g)
