Phosphoryl Chloride Stabilized from China

Stabilized phosphoryl chloride (POCl3 with inhibitors) is a fuming liquid used in phosphate ester production and as a dehydrating agent. Though pure POCl3 is 2812.10, stabilized versions with inorganic additives fall under HTS 2812.90.00 as other halide oxides of nonmetals. Chemically defined and excluded from organic chapters.

Import Tips

Provide stabilizer composition details; if >1% organic, risks reclassification to Chapter 29

UN 1802 labeling required; glass-lined containers prevent corrosion during transit

Pre-clear TSCA pre-notice if new chemical use; common error is bulk vs packaged distinction
