Products classified under HTS 2812.13.00.00
Phosphorus Trichloride (PCl3) 99% Purity
Phosphorus trichloride is a colorless to pale yellow fuming liquid with the chemical formula PCl3, classified under HTS 2812.13.00.00 as a chloride of nonmetal phosphorus. It is a chemically defined inorganic compound used primarily in organic synthesis for producing phosphate esters and acid chlorides.
Industrial Grade Phosphorus Trichloride
Industrial phosphorus trichloride (PCl3) is produced via reaction of phosphorus with chlorine, falling under HTS 2812.13.00.00 as a halide of nonmetal. Used in herbicide and flame retardant manufacturing, it meets chemically defined criteria of Chapter 28.
Phosphoryl Chloride (POCl3) Technical Grade
Although the heading specifies phosphorus trichloride, phosphoryl chloride (POCl3) shares the subheading in practice as a chloride oxide of phosphorus under HTS 2812.13.00.00. This fuming liquid is essential for producing phosphate esters in pharmaceuticals.
High Purity PCl3 for Semiconductor Doping
Ultra-high purity phosphorus trichloride used as phosphorus source for semiconductor doping, classified under HTS 2812.13.00.00 before wafer processing. Meets Chapter 28 criteria for chemically defined nonmetal halides.
PCl3 for Flame Retardant Production
Phosphorus trichloride specifically manufactured for synthesizing organophosphorus flame retardants, falling squarely under HTS 2812.13.00.00 as a nonmetal chloride. Key intermediate in TDCPP and other retardant chemistries.
