HSN Code Details
Unlike HSN 25309040, which covers unprocessed wollastonite, code 25309050 applies to wollastonite that has been calcined or otherwise processed, resulting in a finer, more uniform powder used for industrial purposes. This material appears as a white to off‑white granular or powdered mineral with a Mohs hardness of about 4.5.
When shipping under this heading, exporters should use moisture‑proof, sealed bags or bulk containers to prevent clumping, and include a certificate of analysis confirming the calcination grade; note that the product is freely exportable from India without a license.
