Import Basic Chrome Sulphate — Buy in wholesale FOB from Supplier in India

Basic Chrome Sulphate from Hwatsi Chemical Pvt. Ltd. is a trivalent chromium compound produced by the reduction of chromate salts with sulfur dioxide, yielding a product with 33% basicity as standard for tanning applications. The chemical process formally converts sodium dichromate into chromium sulfate with sodium sulfate as a byproduct, which remains inert in leather treatment. This grade is specifically formulated to ensure full reduction of hexavalent chromium to trivalent, minimizing health risks in leather production and downstream use.

The material is supplied as a fine, free-flowing powder with consistent particle size for uniform dissolution in tanning liquor. Sodium sulfate, a residual from production, does not interfere with the tanning process and is typically retained in the technical grade. Higher basicity variants, such as 42% or 50%, can be achieved by adding sodium carbonate and are often paired with sodium formate for specialized leather finishes. The product adheres to industry-standard purity levels for chromium content, with typical values exceeding 22% Cr2O3 by weight in commercial grades.

This compound is primarily used in the leather industry for chrome tanning, where it imparts durability, flexibility and resistance to heat and water. Buyers include tanneries, footwear manufacturers and producers of leather goods who require reliable chemical performance in bulk volumes. Packaging is typically in 25 kg or 50 kg HDPE bags with inner liners, suitable for sea freight under FOB or CIF terms. Confirm bulk density, pH range and heavy metal limits with the supplier, as these can vary by production batch and intended application.

Hwatsi Chemical Pvt. Ltd. operates from Mumbai, Maharashtra, with its registered office and warehousing facility located at Antop Hill Warehousing Complex, Salt Pan Road. The company specializes in the production and supply of chemical intermediates for industrial applications, including leather processing. Its harbor-tier trust status on the platform reflects a verified business presence, though current response metrics are not available, indicating a need for direct contact for trade inquiries.

The supplier focuses on bulk chemical manufacturing, with Basic Chrome Sulphate as a core product for the leather industry. No additional certifications, production capacity, or client details are provided in the listing, so buyers should request documentation such as COAs, MSDS and ISO compliance directly. The absence of a stated MOQ or lead time suggests flexibility, but these must be confirmed during negotiations. All logistics, including port of shipment and Incoterms, are to be agreed upon with the supplier.
