Import Bentonite Lumps — Buy in wholesale FOB from Supplier in India

Winsome Minerals supplies natural bentonite lumps in sodium and calcium grades from their base in Bhuj, Gujarat, a region accounting for the majority of India's bentonite production due to extensive Kutch basin deposits. The material is sourced directly from certified mines, with stated moisture content between 8-12% at point of supply, and is offered in 1 MT big bags or bulk container shipment for industrial applications. The lumps are described as suitable for oil and gas drilling fluid formulations, iron ore pelletizing, foundry sand bonding, and civil engineering waterproofing, indicating a multi-sector industrial positioning rather than refined consumer-grade material. Buyers should note that while the supplier references certified mines, no specific certification bodies, standards, or accreditation details are provided in the source data, requiring direct verification.

The base material is natural bentonite clay from the montmorillonite group, with typical swelling indices for sodium-grade Gujarat bentonite ranging 25-35 ml/2g and liquid limits of 300-500%, though these specific values are not confirmed for Winsome Minerals' particular source. The lump form as-mined material requires milling and classification for most industrial applications: drilling fluids demand particle size below 200 mesh (75 microns), pelletizing requires 75-250 micron fractions, and foundry applications need specific AFS grain fineness numbers. The 8-12% moisture range quoted sits within typical run-of-mine parameters for Indian bentonite, though end-users in moisture-sensitive applications such as pelletizing may require additional drying. The supplier's mention of bio-stability and heat resistance in their description suggests awareness of foundry and drilling applications where thermal degradation of bentonite gel structure is a performance concern.

Primary buyers span oilfield services companies, iron ore pellet producers, foundries, and civil engineering contractors requiring native sodium or activated calcium bentonite for slurry wall construction or landfill liner applications. Winsome Minerals' location in Bhuj provides access to Mundra and Kandla ports on the Gujarat coast, reducing inland logistics costs compared with inland Indian suppliers. The supplier does not state specific MOQ, pricing, or lead times, though 1 MT big bag presentation suggests minimum order flexibility for trial quantities. Payment terms, Incoterms, and export documentation capabilities require confirmation. Buyers in the drilling sector should request American Petroleum Institute (API) specification 13A test data, while pelletizing customers need ISO 11228 tumble index compatibility and swelling index at 950°C for their specific ore blend.

Winsome Minerals operates from Bhuj in the Kutch district of Gujarat, India, with a registered office address at B/h Shivam Saree, opposite Rajlaxmi Furniture on Anam Ring Road. The company's operational model involves sourcing natural bentonite lumps directly from certified mines, though no mine names, lease details, or certification specifics are disclosed in the available data. The trust tier is listed as harbor, with a 0.00% response rate and zero average response hours, indicating limited or no engagement history through the platform channel. This profile suggests a small-to-medium enterprise focused on raw material extraction and primary processing rather than refined product manufacturing or extensive export operations.

The supplier describes itself as a reputed organisation offering superior quality bentonite lumps processed with latest methodology in sync with international standards, though no specific processing equipment, quality control protocols, or standards are named. Claims of excellent bio-stability and heat resistance align with foundry and drilling applications but lack supporting test data or customer references in the source material. The company does not disclose employee count, annual turnover, export destinations, or existing clientele. Buyers are advised to request company registration documents, mining leases or royalty payment records, and any ISO or industry certifications claimed. Given the Gujarat location, verification through the Gujarat Minerals and Geotechnical Development Corporation or local mining department may provide additional assurance of operational legitimacy.
