Export bans on tungsten and battery scrap (black mass) took effect today. Led by the Commerce Department, the temporary rule will last for one year.
The restrictions are intended to increase domestic recovery of critical minerals. Doing so, however, will require additional processing capacity to absorb the domestically retained material.
The government is already investing in that buildout. Last week, the Energy Department announced $500 million for projects spanning battery recycling, manufacturing, and critical-mineral processing—including one project to process black mass and another to recycle battery materials directly into cathode active material.
But new capacity will take time to come online. In the interim, key questions remain: How broadly will waivers be used if there are no domestic buyers? And will the government show willingness to step in as an interim buyer? Two weeks before the restrictions were announced, the National Defense Stockpile had issued a request for information on the potential acquisition of tungsten hard scrap.
The Trump administration has rolled out a cluster of trade restrictions targeting critical supply chains️ over the past few weeks, affecting the following: 1) new foreign-made advanced robots 2) foreign connected power inverters 3) polysilicon and its derivatives 4) tungsten waste 5) battery scrap.
The measures have not been uniform in mechanism or duration. Some are import bans, another is a tariff paired with a price floor, and others a year-long export restriction.
But together, they signal that minerals, energy, and technology supply chains have become a central axis of U.S. trade and national-security policy, largely aimed at reducing dependence on China and promoting domestic production, and we can expect to see more.
Overview of recent export and import restrictions:
➡️Foreign-made advanced robots and connected power inverters: The Federal Communications Commission added new mobile robots, including humanoid and quadruped robots (advanced robots), plus connected power inverters, to its Covered List, barring them from U.S. import and marketing authorization.
➡️Polysilicon and its derivatives: Not a ban, but 15% tariffs through Section 232 and new minimum import prices on polysilicon, wafers, solar cells, and modules, paired with incentives for domestic production.
➡️Tungsten waste and battery scrap: A one-year export ban with waivers available.
