South Africa is emerging as key player in US critical minerals supply chain

Africa is becoming an increasingly vital source of critical minerals for the United States, particularly those essential for advanced manufacturing, clean energy, and defense technologies.

Among the continent’s key contributors, South Africa is emerging as a dominant supplier, crucial to the US supply chain for several key resources.

The US is heavily reliant on imports for several critical minerals, with countries like Gabon and South Africa playing pivotal roles, while South Africa is a leading supplier of four major minerals: platinum, chromium, palladium, and zirconium.

Africa is central to US supply, other nations, including Chile, Canada, Norway, and China, also contribute significantly to the global supply chain.

According to data from the US Geological Survey, which tracks major suppliers from 2021 to 2024, the US continues to depend on foreign imports for many critical minerals, many of which are sourced from Africa.

Among the most notable minerals, manganese stands out, with the US is entirely dependent on imports for manganese, with Gabon being its primary supplier.

Manganese is crucial for steel production and battery technologies, making Gabon an essential player in the US industrial supply chain.

South Africa, however, is the most influential supplier from Africa, providing the US with significant quantities of platinum (89% import reliance), chromium (79%), palladium (57%), and zirconium (less than 25%).

These minerals are indispensable in a variety of applications, from catalytic converters and fuel cells to aerospace components and nuclear technologies.

Platinum group metals, which are abundant in South Africa, are crucial for hydrogen technologies and emissions control systems.

Meanwhile, chromium plays a key role in stainless steel production, making South Africa’s supply chain indispensable.

Though Africa plays a central role, the US continues to rely on a broader, interconnected global network.

In total, the US is import-dependent for 37 critical minerals, with 11 sourced entirely from abroad.

Beyond Africa, countries like Chile, Canada, and Norway are vital for supplying lithium, copper, nickel, zinc, and cobalt—critical materials for electrification and clean energy systems.

China, meanwhile, remains a dominant force in several categories, particularly graphite, rare earth elements, arsenic, and tantalum.

Its control over rare earth processing capacity shapes global supply chains, presenting strategic vulnerabilities for the US.

In this context, Africa’s resource base offers an opportunity for the US to diversify its supply chains and reduce dependency on any single nation.

South Africa’s key role in supplying platinum group metals, vital for hydrogen technologies and emissions control, positions it as an important partner in the US energy transition.

As global demand for critical minerals continues to rise, Africa’s role in supplying these essential materials is expected to expand, solidifying its position in the evolving global supply chain.

This growing importance underscores Africa’s strategic role, particularly as the US navigates its reliance on multiple regions to meet the demands of the energy transition.
