Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If purely phosphorus-based halide oxide
Phosphoryl chloride (POCl3) specifically heads 2812.10; sulfur compounds remain in .90.
If as complex salts of thiocarbonates
Chapter notes direct complex salts including thiocarbonates to 2842, not simple halide oxides.
If mixed with organic stabilizers for specific use
Mixtures containing halide oxides with organics may classify as preparations in 3812.

Thionyl Chloride
Thionyl chloride (SOCl2) is a colorless liquid used as a chlorinating agent in organic synthesis for converting carboxylic acids to acid chlorides. It falls under HTS 2812.90.00 as a halide oxide of nonmetals, specifically sulfur oxychloride, distinct from pure halides like phosphoryl chloride in 2812.10. This chemically defined inorganic compound is essential in pharmaceutical and agrochemical manufacturing.
Phosphoryl Chloride Stabilized
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.
Selenium Oxychloride
Selenium oxychloride (SeOCl2) is an oily liquid used as a chlorinating agent in analytical chemistry and selenium compound synthesis. Falls under HTS 2812.90.00 as a halide oxide of nonmetals (selenium-chlorine oxide), chemically defined and not doped for electronics per notes. Highly reactive and moisture-sensitive.
Arsenic Oxychloride
Arsenic oxychloride (AsOCl3) is a colorless fuming liquid employed in organic synthesis and glass production. Classified in HTS 2812.90.00 as other halide oxides of nonmetals, it is chemically defined under Chapter 28 and used sparingly due to toxicity.
Tellurium Oxychloride
Tellurium oxychloride (TeOCl2) is a white crystalline solid used in semiconductor doping and analytical standards. It falls under HTS 2812.90.00 as a halide oxide of nonmetals, pure and undoped per chapter notes, distinguishing from electronic forms.
Carbonyl Fluoride
Carbonyl fluoride (COF2) is a colorless, highly toxic gas used in fluorocarbon production and as a fluorinating agent. It classifies under HTS 2812.90.00 as a halide oxide of nonmetals (fluoride oxide of carbon), meeting Chapter 28 chemically defined criteria. Primarily for specialty chemical synthesis.
