HS Code for Sulfur monochloride

Sulfur monochloride, chemically represented as S2Cl2 and also known as disulfur dichloride, is classified under HS code 2812.15. This classification falls within Chapter 28, which covers inorganic chemicals, and specifically under heading 2812, which is reserved for halides and halide oxides of non-metals. The classification is determined by the chemical composition of the substance as a binary compound of sulfur and chlorine. As an inorganic halide, it must be categorized here rather than under organic chemicals or mineral products. Sulfur monochloride is a golden-yellow liquid at room temperature and is primarily used as a vulcanizing agent for rubber and as an intermediate in the production of various sulfur-containing chemicals. The HS nomenclature specifically identifies sulfur monochloride in the 2812.15 subheading to distinguish it from other sulfur halides like sulfur dichloride or thionyl chloride, ensuring precise tracking for international trade and safety regulations.

Common Misclassification

Sulfur monochloride is frequently confused with sulfur dichloride, which is classified under HS code 2812.16. While both are sulfur halides, they have different chemical structures and reactivity profiles. Another common error is misclassifying it under HS code 2812.17, which is specifically for thionyl chloride (SOCl2), a halide oxide. Importers must ensure the chemical formula is verified to distinguish between 2812.15 and 2812.16, as the chlorine-to-sulfur ratio differs.

FAQ

What is the HS code for sulfur monochloride?

The specific HS code for sulfur monochloride is 2812.15.

Is sulfur monochloride classified as a hazardous material for shipping?

Yes, while the HS code identifies the product for customs, it is also regulated under UN number 1828 due to its corrosive and reactive nature when exposed to moisture.
