Import Bleaching Powder — Buy in Bulk from Supplier in India

Bleaching powder from N.S.Trexim (P) Ltd. is a calcium hypochlorite-based chemical compound manufactured in India, primarily valued in B2B markets for its oxidative bleaching and broad-spectrum disinfection capabilities. The product is supplied in bulk format targeting textile mills, water treatment operators, and sanitation contractors who require consistent chlorine release for industrial-scale operations. N.S.Trexim (P) Ltd. operates from Kestopur, Kolkata, with this listing carrying a harbor trust tier and imported supplier classification, though response rate data is currently unavailable.

The active constituent, calcium hypochlorite Ca(ClO)2, typically delivers available chlorine in the range of 30-35% by weight for standard commercial grades, though buyers should request a certificate of analysis to confirm the specific batch potency from this supplier. Industrial bleaching powder decomposes gradually when exposed to moisture, heat, or direct sunlight, releasing chlorine gas and requiring storage in cool, ventilated, dry conditions away from organic materials and acids. Standard packaging for Indian-origin bleaching powder destined for export typically involves HDPE drums with inner polyethylene liners, or multi-layer laminated bags with moisture barrier properties, though the exact format for this listing should be confirmed directly with N.S.Trexim.

Primary import buyers include textile processors seeking fabric whitening and scouring, municipal and industrial water treatment facilities for pathogen control, and sanitation service providers for surface and equipment disinfection. Trade terms commonly associated with Indian chemical exports include FOB (Free On Board) from Kolkata or Haldia ports, CIF destination delivery, with payment structures typically via letter of credit or advance Telegraphic Transfer, though all commercial conditions for this specific supplier require direct negotiation. Import compliance for calcium hypochlorite into most jurisdictions requires adherence to hazardous material shipping regulations, including proper UN classification and MSDS documentation.

N.S.Trexim (P) Ltd. is headquartered at Ae-93/1, Rabindra Pally, Kestopur, Kolkata 700101, West Bengal, India, operating within the Kolkata metropolitan industrial corridor. The company's supplier tier is classified as imported with a harbor trust designation, indicating platform-processed verification rather than independently audited standing. The response rate is recorded at 0.00% with zero average response hours, which indicates either a newly listed profile, a dormant account, or data collection limitations rather than necessarily reflecting current operational capacity.

The listing provides no disclosed manufacturing capacity, year of establishment, workforce size, revenue figures, or named client references, and the source description offers no verifiable third-party certifications, ISO accreditations, or export licence numbers. What is stated is the supplier's location in a major Indian chemical trading hub and their offering of bleaching powder in bulk quantities. Buyers should conduct independent due diligence including verification of business registration, GST identification, and any chemical manufacturing or wholesale distribution licences applicable in West Bengal before committing to orders.
