Sulfur Monochloride 99% Pure
Sulfur monochloride (S2Cl2) at 99% purity is a fuming, yellowish liquid used primarily as a chlorinating agent in organic synthesis. It falls under HTS 2812.15.00.00 as a chloride oxide of sulfur, a nonmetal halide, distinct from metal salts or organic compounds excluded by Chapter 28 notes.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If blended with solvents or stabilizers for retail/industrial application
Mixtures not chemically defined fall under 3824 as other chemical preparations, per exclusions in Chapter 28 note 2.
If derived or used as organosulfur intermediate in pharma
Organic derivatives of sulfur compounds shift to Chapter 29, as Chapter 28 excludes organo-inorganic compounds.
If for bulk sulfur refined for chemical production
Pure elemental sulfur is under 2802; monochloride is a halide derivative, but unchlorinated form changes heading.

Import Tips & Compliance
• Classify strictly as chemically defined per Chapter 28 Note 1; provide purity assay and SDS confirming S2Cl2 composition
• Comply with DOT/UN 1828 hazmat regs for corrosive liquids; include proper shipping papers and UN-approved packaging
• Verify no pesticide use to avoid Chapter 38; common pitfall is classifying formulated mixtures instead of pure compound
