HSN Code Details
The glass‑manufacturing sector drives demand for this inorganic compound, which appears as a white, crystalline powder of strontium sulphate. It is chemically inert and highly stable under normal handling conditions.
Because the product is hygroscopic, shipments are typically sealed in moisture‑proof liners inside a 20‑ft dry container, and the commercial invoice must list the HSN code and a statement that it is freely exportable from India without a license.
