Uni-Fuels is a Singapore-based marine fuel reseller and broker serving shipping companies globally. The company's core business is buying bunker fuel from physical distributors and reselling it to shipping customers at a mark-up. Customers include operators of bulk carriers, tankers, container ships, and offshore vessels, mostly based in Southeast Asia, transacting on a per-order basis with no long-term contracts. The main products are VLSFO (Very Low Sulfur Fuel Oil), HSFO (High Sulfur Fuel Oil), MGO (Marine Gas Oil), and bio marine fuels. Uni-Fuels also operates a small brokerage business, connecting buyers and sellers for a commission, though this is negligible compared to the reseller operation. Profitability is driven by the spread between purchase and selling prices, transaction volume, and the ability to extend trade credit to customers — a key competitive tool since many smaller shipping companies depend on supplier financing to fund fuel purchases. Uni-Fuels pays suppliers quickly but extends 30–60 day credit terms to customers, creating a funding gap it bridges through bank facilities and capital markets. Uni-Fuels is headquartered in Singapore, the world's largest bunker port, and has expanded to offices in Dubai, Shanghai, Limassol, Seoul, and Bangkok. Growth strategy centers on scaling volume through geographic expansion, broadening its supplier base, growing trade financing capacity, and building exposure to alternative fuels like LNG and biofuels as emissions regulations tighten.
