Triphenyl Phosphate Plasticizer
Triphenyl phosphate is an aromatic phosphoric ester used primarily as a flame-retardant plasticizer in the production of flexible polyvinyl chloride (PVC) plastics. It falls under HTS 2919.90.1500 as a specific aromatic plasticizer within the phosphoric esters category, meeting the chapter's criteria for chemically defined organic compounds with phosphorus directly linked to carbon via oxygen. This classification distinguishes it from non-aromatic or non-plasticizer variants.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If used for non-plasticizer applications like flame retardants in textiles
Non-plasticizer phosphoric esters fall under the broader 'other' aromatic category, as plasticizer intent changes the specific subheading.
If imported as a formulated mixture with solvents or stabilizers exceeding chapter note limits
Mixtures not qualifying as simple solutions under chapter note (e) shift to prepared chemical mixtures, excluding pure compounds.
If containing significant sulfur impurities directly linked to carbon
Organo-sulfur compounds take precedence per chapter notes if sulfur atoms are present beyond allowed impurities.

Import Tips & Compliance
• Verify purity and ensure certificate of analysis confirms it meets triphenyl phosphate specifications to avoid reclassification; declare as plasticizer use only to prevent scrutiny under pesticide headings; check for REACH compliance if sourced from EU for easier customs clearance
