Products classified under HTS 2931.59.00

Tris(2-chloroethyl) Phosphate (TCEP)

Tris(2-chloroethyl) phosphate is a halogenated organo-phosphorus compound used primarily as a flame retardant in plastics, textiles, and polyurethane foams. It falls under HTS 2931.59.00 as a halogenated organo-inorganic compound with phosphorus and chlorine directly linked to carbon atoms, not classifiable as sulfonated or halogenated derivatives of other headings.

Tris(1,3-dichloro-2-propyl) Phosphate (TDCPP)

TDCPP is a chlorinated tris phosphate ester used as a flame retardant in flexible polyurethane foams for furniture and automotive applications. Classified under HTS 2931.59.00 as a halogenated organo-phosphorus derivative with multiple chlorine atoms attached to carbon.

Tris(2-chloroisopropyl) Phosphate (TCPP)

TCPP is a low-volatility chlorinated phosphate ester serving as a reactive and additive flame retardant in rigid polyurethane foams and coatings. It qualifies for HTS 2931.59.00 due to its halogenated organo-phosphorus structure with chlorine-carbon bonds.

2-Chloro-1,3,2-dioxaphospholane 2-Oxide

This cyclic chlorophosphate compound serves as a reactive intermediate for synthesizing flame retardants and polymer additives. Falls under HTS 2931.59.00 as a halogenated organo-phosphorus derivative with phosphorus-chlorine and carbon-linked structures.

Chloromethylphosphonic Acid

Chloromethylphosphonic acid is a halogenated phosphonic acid used in agrochemical synthesis and metal surface treatment. Classified in HTS 2931.59.00 for its chloromethyl group directly attached to phosphorus with carbon linkage.

Diethyl Chloromethylphosphonate

This phosphonate ester with chloromethyl substitution serves as a pharmaceutical intermediate and reagent in organic synthesis. HTS 2931.59.00 applies due to halogenated organo-phosphorus structure meeting chapter note requirements.

Bis(2-chloroethyl) Phosphonate

A difunctional chlorophosphonate used in flame retardant polymer synthesis and as a cross-linking agent. Falls under HTS 2931.59.00 as a halogenated organo-phosphorus compound per chapter definitions.
