HS Code for Phosphorus trichloride

Phosphorus trichloride (PCl3) is classified under HS code 2812.13. This falls under heading 2812, which encompasses halides and halide oxides of non-metals. Phosphorus trichloride is a colorless or slightly yellow fuming liquid that is highly toxic and corrosive. It is a key precursor in the manufacture of a wide range of products, including organophosphorus pesticides, plasticizers, flame retardants, and pharmaceutical intermediates. The classification is determined by its chemical identity as a binary halide of phosphorus and chlorine. Within heading 2812, the system differentiates between various phosphorus halides based on the number of halogen atoms and the presence of oxygen. PCl3 is specifically isolated in subheading 2812.13 to facilitate monitoring and trade statistics. Due to its volatility and reactivity, it is subject to stringent shipping regulations and international monitoring under the Chemical Weapons Convention.

Products Included

• Phosphorus(III) chloride

Common Misclassification

Phosphorus trichloride is often confused with phosphorus pentachloride (HS code 2812.14) or phosphorus oxychloride (HS code 2812.12). Accurate classification depends on the specific molecular structure and the absence of oxygen in the halide. It is also sometimes mistaken for sulfur chlorides, such as sulfur monochloride (HS code 2812.15) or sulfur dichloride (HS code 2812.16), due to their similar fuming liquid appearance and industrial roles as chlorinating agents. However, the central atom (phosphorus vs. sulfur) dictates the correct subheading. Importers must ensure that the chemical formula PCl3 is clearly stated on all shipping documents to avoid confusion with these other hazardous halides and to ensure proper duty rates.
