STONEWIN LLC

STONEWIN LLC specializes in the procurement and delivery of refined petroleum products to meet critical military operational requirements. The company’s core capabilities center on the supply of defense-grade fuels—including diesel, gasoline, and marine gas oil—ensuring reliable energy support for naval, ground, and air assets across global theaters. Their technical expertise lies in logistics coordination, fuel specification compliance, and just-in-time delivery of military-grade hydrocarbons under stringent DoD quality and safety standards. Key differentiators include consistent adherence to MIL-DTL-83133 and ASTM D975 specifications, seamless integration with Defense Logistics Agency supply chains, and proven ability to manage complex distribution networks in austere environments. The contractor maintains an exclusive and sustained relationship with the Department of Defense, consistently fulfilling fuel supply contracts across multiple branches, including the U.S. Navy and Army. Their work supports forward-deployed units, expeditionary bases, and maritime operations, demonstrating deep familiarity with military fuel handling protocols, storage requirements, and contingency logistics. The primary NAICS code, 324110—Petroleum Refineries—reflects their role as a critical link in the defense energy supply chain, sourcing and distributing refined petroleum products rather than refining crude themselves. This positions them as a specialized logistics and distribution vendor within the defense energy sector, serving high-priority, mission-critical fuel needs. STONEWIN LLC is a small business structured as a 2L entity, headquartered in Miami, Florida. While currently holding no formal government certifications, their consistent performance with the Department of Defense underscores their reliability as a trusted vendor in defense energy logistics. Their geographic positioning in a major maritime and logistics hub enhances their capacity to support global defense fuel requirements.
