Import Bitumen — Buy in wholesale FOB from Supplier in India

Winwyn Overseas Corporation supplies Penetration Grade Bitumen 60/70 from India, a standard paving grade binder used extensively in road construction and maintenance across tropical and temperate climates. The 60/70 grade denotes a penetration value of 60 to 70 decimillimetres at 25 degrees Celsius under standard loading conditions, indicating medium hardness suitable for hot-mix asphalt in regions with ambient temperatures up to 45 degrees Celsius. This material originates from Indian refineries processing domestic and imported crude slates, with the supplier based in Hyderabad, Telangana, a key logistics hub for bitumen distribution in southern India.

The bitumen comprises vacuum residue from atmospheric and vacuum distillation of crude oil, with typical softening point (Ring and Ball) of 46 to 54 degrees Celsius and ductility at 25 degrees Celsius exceeding 100 centimetres. Solubility in trichloroethylene or carbon disulphide is typically above 99.0 percent, ensuring minimal insoluble impurities. Flash point (Cleveland Open Cup) generally exceeds 230 degrees Celsius, supporting safe handling during elevated-temperature storage and transport. The material is commonly supplied in bulk tankers, steel drums of 180 to 200 kilograms net weight, or bitutainers for ocean freight; typical bulk storage temperature ranges from 150 to 170 degrees Celsius to maintain pumpable viscosity.

Primary applications include dense-graded hot-mix asphalt for highways and urban roads, surface dressing and chip seals, and sprayed seals for pavement preservation. The grade also serves waterproofing membranes, bridge deck surfacing, and airfield runway construction where flexibility and fatigue resistance are required. Buyers typically include national highway contractors, state public works departments, asphalt mixing plant operators, and infrastructure developers across South Asia, Southeast Asia, and East Africa. Trade terms require confirmation directly with Winwyn Overseas Corporation, as the listing does not specify MOQ, pricing, Incoterms, or lead time; buyers should verify ASTM compliance documentation and batch test certificates before shipment.

Winwyn Overseas Corporation operates from a registered address at D.no. 8-2-612/54/2, 3rd Floor, Flat No. 302, Gaffar Khan Colony, Road No. 10, Banjara Hills, Hyderabad, Telangana 500034, India. The supplier holds a Harbor trust tier classification on the platform, though this classification does not constitute third-party certification. The response rate is recorded at 0.00 percent with zero average response hours, indicating no historical messaging data is available; buyers should anticipate potential delays in initial contact and plan sourcing timelines accordingly. The listing presents the company as a supplier of ASTM-standard bitumen for construction and road maintenance, with claimed applications in asphalt production, road paving, roofing, and waterproofing.

The supplier profile does not disclose manufacturing ownership, refinery partnerships, storage terminal locations, annual throughput, or employee count. No verifiable certifications such as ISO 9001, ISO 14001, or product-specific test accreditations are documented in the source material. Buyers must independently verify company registration, tax identification, and any claimed ASTM compliance through direct documentation request. Given the absence of response history, prospective importers should initiate contact well in advance of project deadlines, request reference customers for similar export transactions, and consider appointing an inspection agent in Hyderabad for pre-shipment verification of product quality and packaging integrity.
