Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If phosgene or phosphoryl chloride
Specific nonmetal halide oxides like phosgene head 2812.10; others in .90.
If derived halogenated hydrocarbons
Organic fluorocarbons classify in Chapter 29; excludes Chapter 28 pure inorganics.
If other inorganic compounds like cyanogen halides
Chapter notes place certain complex halides in 2853, but simple COF2 stays 2812.

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.
