JOHANNESBURG, April 4 – Africa is assuming a more prominent role in supplying the United States with critical minerals, as Washington’s reliance on imported inputs for industrial production, energy transition technologies and defense applications remains elevated.
Data compiled by the U.S. Geological Survey and analysed by Visual Capitalist shows the U.S. continues to depend heavily on foreign sources for key materials, with several African countries occupying strategic positions within those supply chains.
One of the clearest examples is manganese, where the U.S. is fully import-dependent. Gabon has emerged as a primary supplier of the mineral, which is widely used in steelmaking and increasingly in battery production, placing the country at a critical junction of industrial and energy value chains.
South Africa remains the continent’s most influential player. The country is a leading source of platinum, chromium, palladium and zirconium for the U.S., with import reliance levels underscoring the depth of that dependence. Platinum group metals, in particular, are central to emissions control systems and hydrogen-based energy technologies, while chromium remains essential for stainless steel manufacturing.
The concentration of these resources highlights Africa’s growing strategic relevance as global demand for energy transition materials accelerates. Palladium and zirconium also play key roles in high-end industrial uses, including aerospace and nuclear applications, further embedding African supply within advanced manufacturing ecosystems.
Despite Africa’s importance, the U.S. supply chain remains globally diversified. Washington is import-reliant on dozens of critical minerals, drawing additional supply from countries such as Chile, Canada and Norway for materials linked to electrification, including lithium, copper and nickel.
At the same time, China continues to exert significant influence, particularly in processing and refining capacity for rare earth elements and other critical inputs. Its dominant position in these segments remains a key concern for policymakers seeking to reduce supply chain vulnerabilities.
Within this shifting landscape, Africa presents an opportunity for the U.S. to diversify sourcing and strengthen supply resilience. South Africa’s position in platinum group metals, combined with Gabon’s role in manganese, underscores the continent’s importance in meeting future demand tied to clean energy systems and advanced manufacturing.
As competition for critical minerals intensifies globally, Africa’s resource base is likely to become even more central to supply chain strategies, reinforcing its role as a key partner in the evolving industrial and energy transition landscape.
