HS Code for Phosphorus trisulfide

Phosphorus trisulfide is classified under HS code 2813.90, which specifically covers sulphides of non-metals, excluding carbon disulfide. This classification is governed by the General Rules of Interpretation (GRI) 1 and 6, which direct the product to Chapter 28 for inorganic chemicals. As a binary compound of phosphorus and sulfur, it is categorized as a non-metal sulphide. The classification is determined by its chemical identity as a separate chemically defined compound. Phosphorus trisulfide, often existing in the form of tetraphosphorus trisulfide (P4S3), is primarily utilized in the manufacture of safety matches and strike-anywhere matches, as well as in the production of various organophosphorus compounds. The classification remains consistent regardless of the physical form, whether it is supplied as a powder, fused mass, or in specialized industrial packaging, provided it does not contain additives that would classify it as a prepared chemical mixture under a different heading.

Products Included

• Tetraphosphorus trisulfide (P4S3)
• Commercial phosphorus trisulphide
• Inorganic phosphorus-sulfur compounds for match manufacturing
• High-purity phosphorus trisulfide for chemical synthesis

Common Misclassification

Phosphorus trisulfide is frequently misclassified under HS code 2813.10, which is reserved exclusively for carbon disulfide. While both are non-metal sulphides, the nomenclature specifically separates carbon disulfide from all other sulphides in this category. Another common error is attempting to classify it under HS code 2804.70, which covers elemental phosphorus. Because the product is a compound (a sulphide) rather than a pure element, it must be moved to heading 2813. Additionally, some importers mistakenly use HS code 3605.00 for matches; however, the raw chemical component must be classified by its chemical composition in Chapter 28, not by the finished product it helps create.

FAQ

What is the HS code for Phosphorus trisulfide?

The HS code for phosphorus trisulfide is 2813.90, which falls under the category of sulphides of non-metals.

Does this code include phosphorus pentasulfide?

Yes, phosphorus pentasulfide (P2S5 or P4S10) is also classified under HS code 2813.90 as it is a non-metal sulphide other than carbon disulfide.
