Duty Rate (from China)
Products classified under Tariff item 2931.46.00
2,4,6-Tripropyl-1,3,5,2,4,6-trioxatriphosphinane 2,4,6-trioxide
2,4,6-Tripropyl-1,3,5,2,4,6-trioxatriphosphinane 2,4,6-trioxide is a specific non-halogenated organo-phosphorus compound with a trioxatriphosphinane ring structure and propyl groups attached to phosphorus atoms. It is classified under tariff item 2931.46.00 as it is explicitly named in the tariff description and meets the definition of an organo-inorganic compound under Chapter 29.
Cyclic Tripropyl Phosphonite Oxide Catalyst Precursor
This specialty chemical grade of 2,4,6-tripropyl-1,3,5,2,4,6-trioxatriphosphinane 2,4,6-trioxide is used as a precursor for phosphinite-based catalysts in hydroformylation processes. It is classified under tariff item 2931.46.00 as the compound is specifically named in the tariff description, regardless of its intended use as a catalyst precursor.
Tripropyl Phosphorothioate Flame Retardant Intermediate
This high-purity grade of 2,4,6-tripropyl-1,3,5,2,4,6-trioxatriphosphinane 2,4,6-trioxide is used as an intermediate in synthesizing phosphorus-based flame retardants for plastics.
