Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing organosulfur heterocycles or derivatives
Organic sulfur compounds classify in Chapter 29; pure inorganic S2Cl2 remains in 2812 per note 2.
If for complex salts with metals
Double salts of nonmetals with metals go to 2842; simple sulfur chloride stays in 2812.
If used in synthetic organic coloring matter production
Pigment intermediates with organic content shift to Chapter 32, excluding Chapter 28 inorganics.

Import Tips & Compliance
• Provide COA confirming >98% S2Cl2; segregate from water-reactive incompatibles during transport
• Register under TSCA for R&D imports; include end-use statement to prevent pesticide classification
