Tricresyl Phosphate (TCP)
Tricresyl phosphate is a triaryl phosphate ester used primarily as a plasticizer and flame retardant in plastics, lubricants, and coatings. It falls under HTS 2919.90.50 as a phosphoric ester (phosphate ester) that is not specifically enumerated elsewhere in heading 2919. This classification applies to its chemical structure as an organic phosphate ester without halogenated, sulfonated, nitrated, or nitrosated derivatives.
Triphenyl Phosphate (TPP)
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.
Tributyl Phosphate (TBP)
Tributyl phosphate is an alkyl phosphate ester extracted for nuclear fuel processing, solvent extraction, and as a plasticizer. It qualifies for HTS 2919.90.50 as an 'other' phosphoric ester without specified modifications. The trialkyl structure fits the phosphoric esters heading per Chapter 29 scope.
Diphenyl Cresyl Phosphate
