Charting America’s Import Reliance of Key Minerals

The push towards a more sustainable future requires various key minerals to build the infrastructure of the green economy. However, the U.S. is heavily reliant on nonfuel mineral imports causing potential vulnerabilities in the nation’s supply chains.

Specifically, the U.S. is 100% reliant on imports for at least 12 key minerals deemed critical by the government, with China being the primary import source for many of these along with many other critical minerals.

This graphic uses data from the U.S. Geological Survey (USGS) to visualize America’s import dependence for 30 different key nonfuel minerals along with the nation that the U.S. primarily imports each mineral from.

U.S. Import Reliance, by Mineral

While the U.S. mines and processes a significant amount of minerals domestically, in 2022 imports still accounted for more than half of the country’s consumption of 51 nonfuel minerals. The USGS calculates a net import reliance as a percentage of apparent consumption, showing how much of U.S. demand for each mineral is met through imports.

Of the most important minerals deemed by the USGS, the U.S. was 95% or more reliant on imports for 13 different minerals, with China being the primary import source for more than half of these.

These include rare earths (a group of 17 nearly indistinguishable heavy metals with similar properties) which are essential in technology, high-powered magnets, electronics, and industry, along with natural graphite which is found in lithium-ion batteries.

These are all on the U.S. government’s critical mineral list which has a total of 50 minerals, and the U.S. is 50% or more import reliant for 43 of these minerals.

Some other minerals on the official list which the U.S. is 100% reliant on imports for are arsenic, fluorspar, indium, manganese, niobium, and tantalum, which are used in a variety of applications like the production of alloys and semiconductors along with the manufacturing of electronic components like LCD screens and capacitors.

China’s Gallium and Germanium Restrictions

America’s dependence on imports for various minerals has resulted in a new challenge resulting from China’s announced export restrictions on gallium and germanium that took effect August 1st, 2023. The U.S. is 100% import dependent for gallium and 50% import dependent for germanium.

These restrictions are seen as a retaliation against U.S. and EU sanctions on China which have restricted the export of chips and chipmaking equipment.

Both gallium and germanium are used in the production of transistors and semiconductors along with solar panels and cells, and these export restrictions present an additional hurdle for critical U.S. supply chains of various technologies that include LED lights and fiber-optic systems used for high-speed data transmission.

The restrictions also affect the European Union, which imports 71% of its gallium and 45% of its germanium from China. It’s another stark reminder to the world of China’s dominance in the production and processing of many key minerals.

The announcement of these restrictions has only highlighted the importance for the U.S. and other nations to reduce import dependence and diversify supply chains of key minerals and technologies.

Why Copper Is a Critical Mineral

From the electrical grid to EVs, copper is a key building block for the modern economy.

Why Copper is a Critical Mineral

Copper is critical for everything from the electrical grid to electric vehicles and renewable energy technologies.

But despite copper’s indispensable role in the modern economy, it is not on the U.S. Critical Minerals list.

This infographic from the Copper Development Association shows what makes copper critical, and why it should be an officially designated Critical Mineral.

Copper’s Role in the Economy

Besides clean energy technologies, several industries including construction, infrastructure, and defense use copper for its unique properties.

For example, copper is used in pipes and water service lines due to its resistance to corrosion and durable nature. As the Biden Administration plans to replace all of America’s lead water pipes, copper pipes are the best long-term solution.

Copper’s high electrical conductivity makes it the material of choice for electric wires and cables. Therefore, it is an important part of energy technologies like wind farms, solar panels, lithium-ion batteries, and the grid. The demand for copper from these technologies is projected to grow over the next decade:

Energy TechnologyAnnual Copper Demand Growth (2021-2035P)Use of Copper
Offshore wind23.3%Undersea cables, generators, transformers
Battery storage21.8%Transformers, wiring
Automotive*14.0%Batteries, motors, charging infrastructure
Solar PV11.9%Wiring, heat exchangers
Onshore wind9.8%Cabling, transformers, substations
Electrical transmission7.2%Transformers, cables, circuit breakers
Electrical distribution2.7%Transformers, cables, circuit breakers

*excludes internal combustion engine (ICE) vehicles.

Furthermore, policies like the Inflation Reduction Act and Bipartisan Infrastructure Law will bolster copper demand through energy and infrastructure investments.

Given its vital role in numerous technologies, why is copper not on the U.S. Critical Minerals list?

Copper and the Critical Minerals List

The USGS defines a Critical Mineral as having three components, and copper meets each one:

  1. It is essential to economic and national security.
  2. It plays a key role in energy technology, defense, consumer electronics, and other applications.
  3. Its supply chain is vulnerable to disruption.

In addition, copper ore grades are falling globally, from an average of 2% in 1900 to 1% in 2000 and a projected 0.5% in 2030, according to BloombergNEF. As grades continue falling, copper mining could become less economical in certain regions, posing a risk to future supply.

The current USGS list of Critical Minerals, which does not include copper, is based on supply risk scores that use data from 2015 to 2018. According to an analysis by the Copper Development Association using the USGS’ methodology, new data shows that copper meets the USGS’ supply risk score cutoff for inclusion on the Critical Minerals list.

Despite not being on the official list, copper is beyond critical. Its inclusion on the official Critical Minerals list will allow for streamlined regulations and faster development of new supply sources.

The Copper Development Association (CDA) brings the value of copper and its alloys to society, to address the challenges of today and tomorrow. Click here to learn more about why copper should be an official critical mineral.

Visualizing 25 Years of Lithium Production, by Country

Lithium production has grown exponentially over the last few decades. Which countries produce the most lithium, and how has this mix evolved?

Lithium Production by Country (1995-2021)

Lithium is often dubbed as “white gold” for electric vehicles.

The lightweight metal plays a key role in the cathodes of all types of lithium-ion batteries that power EVs. Accordingly, the recent rise in EV adoption has sent lithium production to new highs.

The above infographic charts more than 25 years of lithium production by country from 1995 to 2021, based on data from BP’s Statistical Review of World Energy.

The Largest Lithium Producers Over Time

In the 1990s, the U.S. was the largest producer of lithium, in stark contrast to the present.

In fact, the U.S. accounted for over one-third of global lithium production in 1995. From then onwards until 2010, Chile took over as the biggest producer with a production boom in the Salar de Atacama, one of the world’s richest lithium brine deposits.

Global lithium production surpassed 100,000 tonnes for the first time in 2021, quadrupling from 2010. What’s more, roughly 90% of it came from just three countries.

RankCountry2021 Production (tonnes)% of Total
#1Australia 🇦🇺55,41652%
#2Chile 🇨🇱26,00025%
#3China 🇨🇳14,00013%
#4Argentina 🇦🇷5,9676%
#5Brazil 🇧🇷1,5001%
#6Zimbabwe 🇿🇼1,2001%
#7Portugal 🇵🇹9001%
#8United States 🇺🇸9001%
Rest of World 🌍1020.1%
Total105,984100%

Australia alone produces 52% of the world’s lithium. Unlike Chile, where lithium is extracted from brines, Australian lithium comes from hard-rock mines for the mineral spodumene.

China, the third-largest producer, has a strong foothold in the lithium supply chain. Alongside developing domestic mines, Chinese companies have acquired around $5.6 billion worth of lithium assets in countries like Chile, Canada, and Australia over the last decade. It also hosts 60% of the world’s lithium refining capacity for batteries.

Batteries have been one of the primary drivers of the exponential increase in lithium production. But how much lithium do batteries use, and how much goes into other uses?

What is Lithium Used For?

While lithium is best known for its role in rechargeable batteries—and rightly so—it has many other important uses.

Before EVs and lithium-ion batteries transformed the demand for lithium, the metal’s end-uses looked completely different as compared to today.

End-useLithium Consumption 2010 (%)Lithium Consumption 2021 (%)
Batteries23%74%
Ceramics and glass31%14%
Lubricating greases10%3%
Air treatment5%1%
Continuous casting4%2%
Other27%6%
Total100%100%

In 2010, ceramics and glass accounted for the largest share of lithium consumption at 31%. In ceramics and glassware, lithium carbonate increases strength and reduces thermal expansion, which is often essential for modern glass-ceramic cooktops.

Lithium is also used to make lubricant greases for the transport, steel, and aviation industries, along with other lesser-known uses.

The Future of Lithium Production

As the world produces more batteries and EVs, the demand for lithium is projected to reach 1.5 million tonnes of lithium carbonate equivalent (LCE) by 2025 and over 3 million tonnes by 2030.

For context, the world produced 540,000 tonnes of LCE in 2021. Based on the above demand projections, production needs to triple by 2025 and increase nearly six-fold by 2030.

Although supply has been on an exponential growth trajectory, it can take anywhere from six to more than 15 years for new lithium projects to come online. As a result, the lithium market is projected to be in a deficit for the next few years.
