HSN Code Details
The glass‑making and ceramics sector primarily drives demand for high‑purity boric acid that contains more than 85 % H₃BO₃ on a dry‑weight basis. This solid, crystalline material appears as a white powder and is valued for its fluxing and flame‑retardant properties.
When shipping this hygroscopic powder, containers should be sealed in moisture‑proof inner bags and accompanied by a Certificate of Analysis confirming the ≥85 % purity; Indian exporters can do so without obtaining a licence.
