SMB-Winning — a consortium controlled by Shandong Weiqiao (China's largest private aluminum producer) and Winning International (Singapore-registered Chinese shipping firm) — exports ~38.5 Mt/year of Guinea bauxite, almost entirely to China. This Chinese-controlled consortium is responsible for roughly 10% of all global bauxite and operates Guinea's largest export terminal. China effectively controls both the demand side (its refineries) and the supply side (SMB-Winning) of a significant portion of global bauxite trade.
Discovery Alert ↗Did you know2021
SMB-Winning ships bauxite almost exclusively to Chinese alumina refineries that produce aluminum for global supply chains -- including the aluminum in Tesla EV bodies, iPhone cases, aerospace structures, and beverage cans. Guinea bauxite going through a Chinese-controlled consortium to Chinese state alumina refineries creates a supply chain for Western consumer goods (Apple computers, Ford pickup trucks, Coca-Cola cans) that runs entirely through Chinese corporate infrastructure from the mine to the smelter. A Chinese-Singaporean consortium in West Africa controls the upstream raw material supply for a significant portion of global aluminum production that ultimately serves US consumer brands. If Guinea's government (which has had two coups since 2021) disrupts mining licenses, or if China restricts bauxite export to non-Chinese alumina refineries, Western aluminum supply would face significant constraints.
Reuters ↗Origin2023
SMB-Winning was formed in 2015 by a consortium of Chinese and Singaporean companies -- Winning International (Singapore-registered, Chinese-funded), Yantai Port Group (Chinese state-owned Shandong port company), Shandong Weiqiao Aluminium (China's largest private aluminum company), and UMS (United Mining Suppliers) -- specifically to develop Guinea's Boke Region bauxite deposits after Indonesia banned raw bauxite exports in 2014. The Indonesian ban had stranded Chinese alumina refinery capacity that depended on Indonesian bauxite, forcing Chinese aluminum companies to find alternative supply. Guinea, which holds approximately 25% of the world's known bauxite reserves and had been largely underdeveloped due to infrastructure constraints, was the primary alternative. SMB-Winning built the Boffa deepwater terminal, allowing direct shipment of bauxite to China without the road infrastructure Guinea lacked. Within 5 years, the Chinese-backed consortium became Guinea's largest bauxite exporter, shipping almost entirely to Chinese alumina refineries.
