Cyclic Tripropyl Phosphonite Oxide Catalyst Precursor from Japan
Specialty chemical grade 2,4,6-tripropyl-1,3,5,2,4,6-trioxatriphosphinane 2,4,6-trioxide serving as precursor for phosphinite-based catalysts in hydroformylation processes. Falls squarely under HTS 2931.46.00.00 as a non-halogenated organo-phosphorus derivative with defined trioxatriphosphinane structure. Typically packaged in 25kg fiber drums for chemical manufacturers.

Import Tips
• Include technical data sheet confirming CAS registry number and molecular structure matching the tariff description
• Segregate from halogenated phosphorus compounds during storage/shipping to maintain non-halogenated status
• File EPA import certification for new chemical substances if not on TSCA Inventory
