What the rule covers
The Bureau of Industry and Security has announced a one-year ban on exports of black mass, the shredded output of used lithium-ion batteries, and of tungsten scrap used in defence applications. Sellers must supply domestic buyers unless they obtain an exception, and the restriction takes effect later this month. The material carries lithium, cobalt, nickel, manganese and graphite.[1]
President Donald Trump directed the commerce department to draft the restrictions, citing an "inadequate supply" of certain metals that "poses an increasing risk to our national defense and security". The European Union plans comparable restrictions on black mass exports from November 2026. The pricing agency Argus described the measures as unprecedented in recent US history.[1]
The gap between the obligation and the capacity
The first effect of an export ban shows up not in where the material goes but in whose hands it stays. If the processing takes place largely in Asia, an obligation to sell at home redirects ownership first and treatment later. What can be expected in the short run is inventory accumulating in front of the domestic buyer, and the price of that inventory, rather than a rise in refined tungsten output.[1]
One condition makes the opposite possible. If unused processing capacity is standing idle at home, the redirection does not stall at ownership and reaches treatment quickly. The report gives no measure of that capacity, so the difference between the two scenarios will be read from the processing investments announced in the first months rather than from the rule itself.[1]
The exception is where the rule is actually written
Because the ban is open to applications for an exception, it does not amount to an absolute closure. A seller must sell at home yet can obtain an exception, and that structure builds a licensing regime more than an export ban. The restriction's real scope will be settled in the number of exceptions granted and in which buyers they are granted for, not in the published text. That is what has to be measured over the one-year term: how many applications were accepted, and whether shipments of black mass and tungsten scrap to Asia keep appearing in the monthly trade data.[1]
