Home / Chapter 29 / 2931

HSN Code 2931 refers to "Separate chemically defined organo-inorganic compounds (excluding organo-sulphur compounds and those of mercury)." This classification code is essential for identifying specific organo-inorganic compounds for import/export purposes based on their chemical nature and intended use. Common products under HSN Code 2931 include organo-silicon compounds, organo-phosphorus compounds, and organo-nitrogen compounds. Additionally, the GST rate for these specialized chemical compounds under this code supports accurate trade compliance.
