从India供应商批发进口Activated Carbon — FOB条款

Durga Oxides manufactures activated carbon at its facility in Bhuj, Gujarat, India, producing material through a rigorous activation process that develops exceptional adsorption properties for air and water purification applications. The supplier offers multiple grades tailored to specific end-uses, from granular forms for fixed-bed filtration to powdered variants for batch treatment and direct addition processes. The source description emphasises impurity-free production, though buyers should request the actual certificate of analysis to verify ash content, moisture, and residual acid-soluble species for each delivery. Gujarat's chemical manufacturing cluster provides access to feedstock logistics and export infrastructure through Mundra or Kandla ports, positioning the supplier for Middle Eastern and African markets as well as domestic Indian industry. The carbon's adsorptive performance targets contaminant removal across molecular weight ranges, with application-specific grades likely differentiated by pore structure development rather than generic single-specification material.

The activation methodology, whether physical (steam) or chemical (phosphoric acid or zinc chloride), determines the pore size distribution and surface chemistry of the finished carbon. Steam-activated carbons from coconut shell or wood precursors typically develop surface areas of 1000-1200 m2/g with micropore predominance, while chemical activation can tune mesopore fractions for larger molecule adsorption. Durga Oxides states its product is free from impurities, a claim that should be substantiated by ash content below 8% for wood-based or 15% for coal-based material, and by heavy metals limits per IS 877 or ASTM standards. The granular grades will show particle hardness and uniformity coefficient critical to backwash performance, while powdered grades require controlled top-size and dust fraction to prevent transport attrition and respiratory exposure. Buyers should clarify whether the supplier produces to batch consistency or adjusts activation parameters per order.

Application sectors span wastewater treatment plants, air purification system OEMs, food and beverage decolourisation, and chemical process industries throughout India and export markets. Municipal and industrial effluent treatment represents the largest volume use, where activated carbon polishes biological treatment effluent or removes refractory organics in combined processes. Food-grade applications such as sugar refining and edible oil purification require compliance with Food Safety and Standards Authority of India (FSSAI) regulations or equivalent import-country standards. The supplier mentions ISO and SGS certifications without specifics; buyers must request certificate scopes, numbers and validity periods. Payment terms of T/T and L/C are offered with FOB and CIF shipment options, though exact minimum order quantities, lead times and packaging configurations require direct confirmation with Durga Oxides for each inquiry.

Durga Oxides operates from 115 Pooja B, Complex Station Road, Bhuj, Gujarat, 370001, India, in the Kutch district known for its chemical and mineral processing industries. The supplier holds a harbor trust tier on the marketplace, with a published response rate of 0.00% and zero average response hours, indicating no tracked buyer communication history. The profile contains no information about year of establishment, production capacity, workforce size, annual turnover, or ownership structure. Buyers should independently verify the company's registration with the Ministry of Corporate Affairs and its GST compliance status before committing to substantial orders.

The product positioning emphasises manufacturing rather than trading, with customised grades for specific applications. ISO and SGS certifications are mentioned but no details are provided regarding standards, scopes, or audit dates. The supplier lists flexible minimum order quantities and standard international payment and shipping terms. No named customers, export destinations, or project references appear in the profile. Communication responsiveness and technical support depth are unknown quantities that should be evaluated through an initial sample request and specification discussion before larger procurement.
