99% Pure DMMP Flame Retardant Grade
High-purity (99%) dimethyl methylphosphonate is a key flame retardant precursor for polyurethane foams and textiles, fitting HTS 2931.41.00.00 due to its specific organo-phosphorus structure without halogens. It serves as a stable, low-toxicity intermediate in polymer manufacturing.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If contaminated with halogenated impurities exceeding trace levels
Halogenated organo-phosphorus derivatives are classified in subsequent 2931.42 provisions per chapter numerical order rule.
If when pre-mixed as additive for specific polymer compounds
Antiknock preparations or formulated additives for fuels/polymers fall under Chapter 38 if not pure compounds.
If for lower-purity grades resembling saturated acyclic hydrocarbons with phosphorus
Impure forms may be treated as basic organic chemicals if organo-inorganic character is diminished.
