HS Code for Thionyl chloride

Thionyl chloride is classified under HS code 2812.17. This code is found in Chapter 28, which covers inorganic chemicals, precious metals, rare-earth metals, radioactive elements, or isotopes. Heading 2812 specifically covers halides and halide oxides of non-metals. Thionyl chloride (SOCl2) is a halide oxide of sulfur, which is a non-metal. The classification is determined by the chemical composition of the substance as an inorganic halide oxide. Under the 2022 HS nomenclature updates, thionyl chloride was given its own specific subheading (2812.17) to facilitate better monitoring and control of the trade of this substance. It is a highly reactive inorganic compound, appearing as a colorless to yellowish liquid with a pungent odor. It is primarily used as a chlorinating agent in organic synthesis, converting carboxylic acids to acyl chlorides and alcohols to alkyl chlorides. It is also a critical component in the manufacture of lithium-thionyl chloride batteries. The classification follows GRI 1, as the substance is explicitly named in the subheading.

Common Misclassification

Thionyl chloride is sometimes misclassified under 2812.19, which is the residual category for other halides and halide oxides. However, since it has a dedicated code (2812.17), the specific code must be used. It is also occasionally confused with sulfuryl chloride (SO2Cl2), which is classified under 2812.19, or phosphorus chlorides under 2812.13 and 2812.14.
