Import Bentonite — Buy in wholesale FOB from Supplier in China

Jinlin Corundum offers bentonite sourced from China, with a stated chemical formula of (Na,Ca)0.33(Al,Mg)2Si4O10(OH)2-nH2O representing the montmorillonite layer structure. The supplier positions the material for foundation waterproofing, diaphragm wall construction, and soil stabilisation in addition to conventional drilling and foundry uses. Chinese bentonite production is concentrated in regions such as Xinjiang, Zhejiang, and Liaoning, though the exact mine or processing location for this specific material is not disclosed in the listing.

The product is described as refined natural bentonite gel with exceptional swelling properties, available in grades tailored to specific industry requirements. Montmorillonite's swelling derives from water intercalation between negatively charged silicate layers, balanced by exchangeable sodium or calcium cations; sodium-rich varieties generally yield higher swelling volumes and lower permeability, critical for waterproofing membranes and slurry trench cut-off walls. The supplier notes quality control processes without detailing test protocols, particle size methods, or batch release criteria, so buyers should request standardised quality documentation for each delivery.

Construction contractors, geotechnical engineering firms, oilfield service providers, and environmental remediation specialists form the primary market for this bentonite. The listing indicates 25 kg bags or jumbo bags as typical export packaging, with 200-mesh granularity mentioned as a standard specification. Pricing, MOQ, lead times, and precise trade terms are not provided in the source data and must be negotiated directly with Jinlin Corundum; buyers should also confirm whether the Incoterms offered include FOB Chinese port, CIF destination, or alternatives, and what payment instruments the supplier accepts.

Jinlin Corundum is located in Pingluo Town, Shizuishan, Ningxia, China, a region historically associated with corundum and refractory materials production rather than bentonite mining, which may indicate trading or processing rather than extraction. The company holds a harbour trust tier on the platform, yet its response rate is 0.00 percent with zero recorded average response hours, indicating no recent platform-mediated communication. The profile does not disclose factory ownership, production capacity, number of employees, years established, or annual revenue.

The listing describes Jinlin Corundum as offering bentonite for multiple industrial sectors with flexible supply arrangements, but no named certifications, factory audit reports, or customer references appear in the available data. The supplier's primary expertise may lie in corundum and refractory products, with bentonite representing a traded or secondary line. Buyers should verify whether the company processes bentonite in Ningxia or sources it from third-party producers elsewhere in China, and request documentation of supply chain traceability before committing to volume purchases.
