Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If pure sulfur monochloride (S2Cl2) instead of dichloride
Different stoichiometry classifies as separate subheading within 2812.10 for monochloride.
If when complexed with metals for specialty salts
Metal complexes become double salts under 2842 per Chapter notes.

Import Tips & Compliance
• Label as corrosive (8) and toxic (6.1); segregate from water-reactive goods during shipping
• Test for moisture content <0.1% to maintain stability and proper classification
• Avoid bulk imports without stabilization—prone to decomposition causing customs holds

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.
Pharma-Grade Sulfur Dichloride
Pharmaceutical-grade sulfur dichloride meets strict impurity specs for API synthesis, classified in HTS 2812.16.00.00 as a chemically defined nonmetal halide oxide. Distilled under vacuum for highest purity.
Stabilized Sulfur Dichloride Solution
Stabilized sulfur dichloride in solvent carriers prevents polymerization, used in polymer chemistry under HTS 2812.16.00.00 for the core compound. Stabilization doesn't alter its chemical definition per Chapter 28.
Industrial Grade Sulfur Dichloride
Industrial sulfur dichloride is a key intermediate for producing pesticides, pharmaceuticals, and dyes, classified under HTS 2812.16.00.00 due to its chemical definition as a sulfur chloride oxide. It reacts violently with water, requiring inert atmosphere packaging.
