On December 22, 2025, the FCC added foreign-produced drones and UAS critical components to its Covered List. It was, arguably, the loudest thing to happen to this industry in a decade.
It also solved almost nothing about the thing most likely to stop you from delivering.
Because the action everyone is arguing about is a demand-side one. It decides who can get new airframes authorized for the US market. It says nothing about whether the parts inside them can be built.
The layer below the airframe
American drone manufacturing has spent recent years solving the assembly problem. Printed airframes. Distributed shops. Rapid iteration on new designs. That work is real and it matters.
Now go one layer down, to the motors, and look at what they need.
Permanent magnets. Neodymium-iron-boron, sintered — the component that makes a small motor powerful enough to lift a payload without weighing so much that it can’t. Per the International Energy Agency, China accounted for roughly 60% of global mining output in 2024 for the rare earths used in magnets — but that number is the least important one.
The important numbers are downstream. China holds about 91% of global separation and refining for those materials. And it produces 94% of the world’s sintered permanent magnets — up from roughly 50% two decades ago.
The IEA’s broader picture is the same shape: for 19 of the 20 strategic minerals it tracks, China is the leading refiner, at an average share of 70%.
Mining is a commodity. Magnets are a manufacturing monopoly that took two decades of sustained industrial policy to build, and it does not unwind in one appropriations cycle.
Put plainly: you can keep a Chinese drone out of American procurement. You cannot yet build the motor that replaces it without a magnet that, 94% of the time, comes from China.
What April and October told us
This is not theoretical. On April 4, 2025, China imposed export controls on seven heavy rare earth elements plus related compounds, metals, and magnets, the IEA reports.
The result: carmakers in the United States and Europe struggled to obtain permanent magnets. Some were forced to cut utilization rates or temporarily shut down factories. Even after volumes recovered, European prices reached up to six times those in China.
Then on October 9, 2025, the controls widened. The new measures require foreign companies to obtain a Chinese license to export “parts, components and assemblies” containing Chinese-sourced rare-earth materials — or produced using Chinese rare-earth technology. The rule applied with immediate effect to products made in China. From December 1, 2025, it escalated to cover internationally made products containing more than 0.1% by value of Chinese-origin materials, even when traded domestically.
Read that again, because it is the part that should reorganize your procurement plan: a magnet assembled outside China, from Chinese-origin material, may still be caught. Provenance of the finished part is not the answer. Provenance of the material is.
Five more elements — holmium, erbium, thulium, europium, ytterbium — took effect under control on November 8, 2025, along with controls on rare-earth processing equipment for milling, separation, and refining. Holmium matters specifically: the IEA notes that since April 2025, many permanent magnet makers had been revising their approach to replace the previously restricted rare earths with holmium. Months later, holmium was added to the list.
China exported 58,000 tonnes of rare-earth magnets in 2024 — its export volume alone, enough, per the IEA, to build components for millions of cars and industrial motors, or thousands of strategic military systems, data centers and wind turbines.
The uncomfortable asymmetry
Automakers, with billion-dollar purchasing desks and decades of supplier relationships, got squeezed in a single quarter. Drone manufacturers buy magnets in quantities that would not fill a single automaker’s monthly order.
In a shortage, you don’t win the allocation. You get told the lead time.
This is the part of the supply chain conversation that gets skipped, because it isn’t about policy. It’s about leverage, and American drone builders currently have almost none in the one component their motors can’t run without.
What a builder can actually do
- Map your bill of materials down to the magnet. Most manufacturers know their motor vendor. Far fewer know the magnet’s origin, or the origin of the material inside it. You cannot manage a dependency you haven’t documented.
- Design for substitution latitude. Ferrite motors, magnet-light topologies, and designs that tolerate a lower-grade magnet all cost performance on paper. They also cost less than a grounded production line.
- Qualify a non-China magnet source — now, before you need it. US, Japanese, and allied production exists. Getting on a qualified-source list before a shortage is a different price than getting on one during a shortage.
- Treat licensing as schedule risk, not news. A denied or delayed export license is a line item in your delivery plan. Model it.
- Plan materials across the life of the program. Strategic inventory of magnet-bearing components is unglamorous and expensive. So is default.
And at the industry level: domestic magnet capacity is a national security supply problem, and policy support and defense-industrial programs are directing real money at it. Defense Production Act Title III activity, defense manufacturing programs, and SBIR/STTR topics in advanced materials and manufacturing are the front door for builders who want to be part of the fix rather than a victim of the gap.

Why everyone else should care
It is easy to file this as a builder’s problem. It isn’t. The same shortage that delays a delivery schedule grounds the firefighting and disaster-response drones a county was counting on, slows the utility-inspection flights that keep the grid honest, and pushes up the cost of the agriculture drones that decide next season’s input budget. The IEA’s own framing is blunter: 58,000 tonnes of magnet exports is enough material for thousands of strategic military systems. A magnet bottleneck is not an inventory problem with a procurement solution. It is a decision about which capabilities a country can actually field — and it is currently being made somewhere else.
The boring parts own the decade
There’s a version of this market where the US wins by building better airframes. That version is incomplete, because the airframe was never the hardest part.
The hardest part is the motor, and the motor is the magnet, and the magnet is — 94% of the time — someone else’s decision.
A distributed American manufacturing network that prints airframes in hundreds of shops is not resilient if every one of those shops is waiting on the same overseas magnet shipment. Resilience at the top of the stack without resilience at the bottom is a nicer-looking version of the same vulnerability.
Whoever builds the boring parts owns the decade. Right now, we’re not building the boring parts.
