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

Viha impex offers calcined montmorillonite clay powder from Rajkot, Gujarat, positioned for oil and gas drilling, construction waterproofing, and agricultural soil conditioning applications. The material is a naturally occurring smectite clay mineral processed to enhance swelling capacity and adsorption properties for industrial use. For drilling mud systems, buyers typically evaluate bentonite against API 13A or OCMA standards governing yield point, plastic viscosity, and fluid-loss control in freshwater and saltwater formulations. The supplier packs material in 25-50 kg bags or bulk jumbo bags, with moisture management critical to preserving reactivity during storage and ocean transit from Indian west-coast ports.

Calcination, a heat treatment process typically conducted at 150-800 degrees Celsius depending on application, drives off interlayer water and can alter cation exchange capacity. For drilling-grade bentonite, calcination is less common than simple drying, so buyers should clarify whether the material is air-dried or thermally treated, as this affects swelling behaviour and gel strength. Montmorillonite's layered aluminosilicate structure provides high cation exchange capacity (typically 70-120 meq/100g for sodium bentonite) and specific surface area exceeding 200 square metres per gram, enabling effective adsorption of organic contaminants and heavy metals in wastewater treatment. Standard quality parameters include methylene blue absorption, sand content (residue on 200-mesh sieve), and free swell volume, each of which should be batch-certified for critical applications.

Primary buyers include oilfield service companies formulating drilling fluids, waterproofing membrane manufacturers requiring clay additives, agricultural distributors blending soil amendments, and environmental engineering firms deploying permeable reactive barriers. The supplier mentions ISO and SGS certifications though no certificate numbers or scopes are provided. Rajkot's proximity to Kandla and Mundra ports offers logistical advantages for containerised export, though inland transport arrangements and minimum order thresholds must be confirmed directly with Viha impex. Letter of credit and telegraphic transfer payment options are referenced, but specific terms, lead times, and port of loading require direct negotiation.

Viha impex is based at B 705 The One World, 150 Feet Ring Road, near Ayodhya Circle, Rajkot, Gujarat, India. The company operates from this western Indian city, which functions as a commercial and manufacturing hub with access to Kandla and Mundra seaports for export-oriented trade. The supplier profile carries organic tier and voyage trust tier classifications, but records a zero percent response rate with no average response time data. This communication gap means buyers should not assume prompt replies and should plan for extended enquiry and negotiation cycles before orders are confirmed or production slots allocated.

The listing does not disclose year of establishment, ownership structure, factory location, production capacity, employee count, or named customers. What is communicated is a focus on wholesale and bulk supply, claims of ISO and SGS certification without supporting documentation, and product positioning across construction, agriculture, and drilling sectors. Buyers should independently verify ISO certificate registration numbers through accredited bodies, request SGS inspection reports if available, and ask for photographic or video evidence of processing facilities and quality control stations. Given the limited verification signals, a site visit or appointment of a local inspection agent in Raj或者以 Rajkot may provide necessary confidence before committing to large-volume contracts.
