Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If prepared as additive for rubber vulcanization with organic stabilizers
Rubber accelerators with organic components fall in 3812, excluding pure inorganic halides of Chapter 28.
If for sodium or metal sulfides used similarly in industry
Metal sulfides classify under 2830 per heading 2826-2842 notes for salts; nonmetal halides stay in 2812.
If sold as diagnostic reagent mixture
Reagent-grade mixtures not chemically defined go to 3824, per Chapter 28 exclusions for preparations.
