Import Bentonite — Buy in Bulk from Supplier in India

N.S.Trexim (P) Ltd. supplies bentonite from Kolkata, West Bengal, positioning the company near India's eastern seaboard with access to Paradip, Haldia, and Kolkata ports for export shipment. The product is marketed primarily for drilling applications, with emphasis on swelling capacity, viscosity generation, and chemical inertness in drilling fluid systems. The supplier notes availability in multiple grades without specifying API, OCMA, or other standard designations, so buyers should request grade classification and conformance data. Indian bentonite deposits, notably in Rajasthan and Gujarat, typically yield calcium bentonite requiring sodium modification for premium drilling applications, though the supplier's source region is not disclosed. Packaging and exact bag weights are not specified, requiring direct confirmation for logistics planning.

The material's swelling capacity is highlighted as a key performance attribute, with typical sodium-exchanged bentonites achieving 15-30 mL/2g free swell depending on purity and exchangeable sodium percentage. Viscosity development, measured as apparent viscosity or plastic viscosity in standard oilfield tests, depends on solids concentration, particle size distribution, and degree of beneficiation. Chemical inertness in the source description refers to non-reactivity with common drilling fluid additives, pH buffers, and formation fluids, a standard expectation rather than a differentiating feature. Indian bentonite production historically served local foundry and iron ore pelletising markets before expanding into oilfield supply, so processing infrastructure and quality culture vary significantly between producers. The supplier's mention of FSSAI certification suggests possible food-grade handling capability or cross-contamination controls, though this is speculative without certificate review.

Oil and gas drilling contractors, geothermal and water well operators, and mining sector trenching specialists form the core buyer segments for this product. Construction applications include slurry wall support and foundation waterproofing, while environmental remediation uses bentonite for cut-off walls and capping layers. The supplier offers FOB and CIF trade terms without naming specific ports or pricing structures. Minimum order quantities are described as flexible but not quantified, a pattern that requires clarification to avoid ambiguity. Response rate and average response time data show zero values, indicating potential listing inactivity or data collection issues that buyers should factor into communication planning.

N.S.Trexim (P) Ltd. is registered at Ae-93/1, Rabindra Pally, Kestopur, Kolkata 700101, in West Bengal, India. This Kolkata suburban address places the company in India's eastern commercial hub, though no manufacturing facility, warehouse, or mine location is mentioned in the available data. The supplier tier is imported with harbor trust tier, indicating basic platform listing status without advanced verification. Response metrics show 0.00 rate and zero average hours, suggesting either a recently created listing, dormant account, or incomplete data integration rather than established trading history. Buyers should treat this profile as requiring full independent verification before engagement.

The company profile contains no stated founding date, ownership structure, employee count, annual turnover, or export experience. No manufacturing licences, mining rights, or processing capabilities are described. The source description attributes various claims to the platform rather than to verified company statements, creating ambiguity about what N.S.Trexim (P) Ltd. itself represents versus generic marketing content. FSSAI certification, if genuine and current, would imply food safetydaa handling standards that may or may not relate to bentonite operations. Buyers should request company registration documents, PAN, GST registration, and any export-import code to establish legal existence and trading authority before advancing discussions.
