HS Code for Sodium thiocyanate

Sodium thiocyanate is classified under HS code 2842.90. This classification falls under Chapter 28, heading 2842, which serves as a category for "other salts of inorganic acids or peroxoacids (including aluminosilicates whether or not chemically defined), other than azides." Unlike silicates, sulphates, or sulphides, thiocyanates do not have a specific named heading in the 2826-2841 range of the Harmonized System. Therefore, they are classified in the residual heading 2842. Sodium thiocyanate, also known as sodium rhodanide, is an inorganic compound used as a precursor for pharmaceuticals, as a solvent for polyacrylonitrile in fiber spinning, and in the construction industry as an accelerator for concrete hardening. The classification remains 2842.90 regardless of whether it is in crystalline form or an aqueous solution, provided it is not mixed with other substances to form a preparation. It is a colorless, deliquescent salt that is highly soluble in water. Because it is an inorganic salt of thiocyanic acid, it must be distinguished from organic thiocyanates which are found in a different chapter of the HS nomenclature.

Common Misclassification

Often misclassified under 2837.20 (Complex cyanides) because thiocyanates contain the -CN group; however, they are chemically distinct from cyanides and are not considered complex cyanides. It may also be confused with organic thiocyanates, which are classified in Chapter 29 under 2930.90 as organo-sulfur compounds.

FAQ

What is the HS code for sodium thiocyanate?

The HS code is 2842.90.

Is sodium thiocyanate toxic?

While it is significantly less toxic than sodium cyanide, it is still considered harmful if swallowed and requires careful handling and appropriate safety data sheets (SDS) for international trade.
