Sulfur Dichloride 99% Purity
Sulfur dichloride (Cl2S2) is a chemically defined chloride oxide of sulfur, a fuming yellow liquid used primarily as a chlorinating agent in organic synthesis. It falls under HTS 2812.16.00.00 as a halide oxide of nonmetals, specifically sulfur dichloride, meeting Chapter 28 definitions for inorganic compounds. Typically supplied in specialized glass or steel containers due to its reactivity.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified as a simple chloride rather than chloride oxide
Misinterpretation as other sulfur chlorides like chlorosulfonic acid shifts to halides of sulfites/sulfuric acid in 2829.
If when prepared mixtures for specific rubber accelerator production
Blended preparations for vulcanization fall under Chapter 38 as chemical preparations, not pure compounds.
If chemically modified into organosulfur derivatives
Organic derivatives like sulfonyl chlorides move to Chapter 29 for organic sulfur compounds.

Import Tips & Compliance
• Classify as UN1836 hazardous material; provide Safety Data Sheet (SDS) and ensure DOT-compliant packaging for transport
• Verify purity and chemical identity via certificate of analysis to confirm HTS 2812.16 classification over other sulfur compounds
• Obtain EPA approvals if destined for U.S. chemical production; watch for REACH-like restrictions on imports
