Triphenyl phosphate serves as a flame retardant and plasticizer in rigid PVC, cellulose acetate, and synthetic resins. Classified under HTS 2919.90.50.50 as an 'other' phosphoric ester, it matches the chapter's scope for separate chemically defined organic phosphate compounds. Its aryl phosphate structure distinguishes it from alkyl phosphates listed elsewhere.

Import Tips
• Include CAS number (115-86-6) and purity analysis on commercial invoice to confirm classification as pure phosphoric ester
• Check REACH compliance if sourced from EU; US importers need TSCA certification
• Label containers properly to prevent confusion with restricted isomers like TOCP
