These Are the Critical Minerals Exempt from Trump’s Tariffs

Plus 5 that got hit.

President Donald Trump has exempted some — but certainly not all — of the critical minerals necessary for the energy transition from the sweeping tariffs he announced Wednesday. Minerals such as lithium, nickel, cobalt, manganese, and copper are key components of clean energy infrastructure such as lithium-ion batteries, which are used in electric vehicles or stationary storage, and copper wires, which conduct electricity in solar panels and wind turbines.

The White House has published a complete list of hundreds of products that are exempt from tariffs. We combed through the list looking for key transition minerals. Here are the ones that caught our eye, plus some that were notably left off. If you see anything on the list you think we missed, my inbox is open.

Exempt from tariffs

  • Lithium carbonate and lithium hydroxide - Both are precursor materials for lithium-ion batteries. Lithium carbonate is usually used in the less energy dense but cheaper lithium-iron-phosphate (LFP) batteries, while lithium hydroxide is preferred for the higher performance nickel-manganese-cobalt (NMC) batteries.
  • Manganese dioxide - A type of manganese ore from which manganese compounds are produced. These are then used in the cathodes of NMC lithium-ion batteries to enhance stability and performance. Manganese can help offset the need for cobalt in batteries as it’s a cheaper and more abundant material.
  • Cobalt - Also plays an important role in the cathodes of NMC lithium-ion batteries to enhance stability and energy density.
  • Natural graphite (powder or flakes) - Graphite mined from the earth is used as anode material for lithium-ion batteries because of its high electrical conductivity, which allows for fast charging and high power output.
  • Aluminum - A lightweight and easily recyclable material, aluminum is critical for the construction of many clean energy products, such as EV bodies, the frames of solar panels, and wind turbine components.
  • Copper - A very good electrical conductor that’s used in the wiring for solar panels, wind turbines, EV motors, lithium-ion batteries, and power transmission lines. (Okay, this “critical material for energy" isn't technically a critical mineral, but given its importance to the transition, we included it.)

Subject to tariffs

  • Nickel sulfate and nickel oxide - An essential cathode material in NMC batteries that serves to increase energy density.
  • Manganese sulfate - Produced from manganese ores such as manganese dioxide (which is, again, not subject to tariffs). This refined form of manganese is used in the cathodes of NMC lithium-ion batteries.
  • Synthetic graphite - High purity, industrially manufactured graphite, which is preferred over natural graphite for high performance EVs and energy storage systems due to its superior electrical conductivity and cycle life.
  • Iron phosphate - The primary cathode material in LFP batteries, which have seen notable performance improvements in recent years, making them an increasingly popular choice for EVs.
  • Neodymium - A key component in the powerful magnets that are critical to making lightweight EV motors and wind turbine generators.

Utilities Asked for a Lot More Money From Ratepayers Last Year

A new PowerLines report puts the total requested increases at $31 billion — more than double the number from 2024.

Utilities asked regulators for permission to extract a lot more money from ratepayers last year.

Electric and gas utilities requested almost $31 billion worth of rate increases in 2025, according to an analysis by the energy policy nonprofit PowerLines released Thursday morning, compared to $15 billion worth of rate increases in 2024. In case you haven’t already done the math: That’s more than double what utilities asked for just a year earlier.

Trump Loses Another Case Against Offshore Wind

A federal judge in Massachusetts ruled that construction on Vineyard Wind could proceed.

The Vineyard Wind offshore wind project can continue construction while the company’s lawsuit challenging the Trump administration’s stop work order proceeds, judge Brian E. Murphy for the District of Massachusetts ruled on Tuesday.

That makes four offshore wind farms that have now won preliminary injunctions against Trump’s freeze on the industry. Dominion Energy’s Coastal Virginia offshore wind project, Orsted’s Revolution Wind off the coast of New England, and Equinor’s Empire Wind near Long Island, New York, have all been allowed to proceed with construction while their individual legal challenges to the stop work order play out.

Chris Wright Is Overhauling $83 Billion of Loans. He Won’t Say Which Ones.

The Secretary of Energy announced the cuts and revisions on Thursday, though it’s unclear how many are new.

The Department of Energy announced on Thursday that it has eliminated nearly $30 billion in loans and conditional commitments for clean energy projects issued by the Biden administration. The agency is also in the process of “restructuring” or “revising” an additional $53 billion worth of loans projects, it said in a press release.

The agency did not include a list of affected projects and did not respond to an emailed request for clarification. However the announcement came in the context of a 2025 year-in-review, meaning these numbers likely include previously-announced cancellations, such as the $4.9 billion loan guarantee for the Grain Belt Express transmission line and the $3 billion partial loan guarantee to solar and storage developer Sunnova, which were terminated last year.
