[SMM Analysis] US Imposes Emergency Restrictions on Lithium Battery Black Mass Exports, Locking in Critical Recycling Raw Materials with Regulations

Against the backdrop of the US accelerating the build-out of its domestic battery supply chain while facing persistent reliance on foreign sources for critical minerals, the Bureau of Industry and Security (BIS) of the US Department of Commerce issued an interim final rule on August 5, 2026, imposing export controls on certain recycled battery materials. The most impactful measure is the temporary export restriction on black mass, an intermediate material from lithium battery recycling. Rather than a complete cutoff of lithium battery-related material exports, this move precisely targets recycled stage products rich in lithium, cobalt, and nickel, aiming to intercept at the source the rapidly growing domestic pool of retired battery resources.

Against the backdrop of the US expediting its domestic battery supply chain yet remaining reliant on critical minerals imports, the Bureau of Industry and Security (BIS) of the US Department of Commerce issued an interim final rule on Aug 5, 2026, imposing export controls on certain recycled battery materials. The most impactful measure was the temporary export restriction on black mass—an intermediate product in lithium battery recycling. Rather than a blanket ban on lithium battery-related material exports, this move precisely targets recycled intermediate products rich in lithium, cobalt, and nickel, aiming to cut off at the source the rapidly growing domestic pool of retired batteries.

The legal basis of this interim final rule is Section 101 of the Defense Production Act of 1950, activated via a presidential determination. Under the DPAS framework, BIS issued a directive allocation order requiring that sales of the relevant materials must first prioritize US domestic demand. Per the rule's definition, "black mass" covers the powdery mixture rich in lithium, cobalt, nickel and other metals obtained after discharging, crushing, and sorting end-of-life batteries, as well as recycled intermediate materials that have undergone preliminary physical processing but have not yet entered the chemical refining stage. Fully assembled new batteries, battery modules, and end-of-life batteries not in this intermediate state are not directly subject to this control measure.

This interim final rule, published in the Federal Register on Aug 6, 2026, will take effect 21 days later, i.e., restriction measures will be fully enforced from Aug 27, 2026. The rule remains valid until Aug 27, 2027.

Currently, global crushing and pretreatment capacity for lithium battery recycling in 2026 stands at approximately 3.42 million mt/year, with China's capacity accounting for around 70%. Recycling enterprises in China are widely distributed and have large capacities, while North America accounts for roughly 7% of global crushing and pretreatment capacity. In the hydrometallurgy recycling segment, China's hydrometallurgy capacity accounts for 80% or more. Moreover, in the Interim Administrative Measures for the Recycling and Comprehensive Utilization of Retired New Energy Vehicle Power Batteries, issued on Apr 1, 2026, recycling efficiency requirements are clearly stipulated: a comprehensive recovery rate of no less than 98% for Ni-Co-Mn and no less than 85% for lithium. At present, the capacity of recycled lithium carbonate in 2025 is 556,000 mt, nickel sulphate 184,000 mt in metal content, and cobalt sulphate 82,000 mt in metal content. Most enterprises achieve a lithium recovery rate above 85%, and nickel and cobalt recovery rates around 97%. China is at the forefront in overall capacity and recovery rates for back-end hydrometallurgy smelting of lithium battery recycling. Although Europe and North America also have hydrometallurgy smelting capacity, most plants are in the trial production stage.

Consequently, in these regions, end-of-life batteries are pre-processed into black mass and sold as an intermediate product to downstream refiners or directly exported to Asia for hydrometallurgical extraction. After the ban takes effect, any black mass without an export license will be unable to leave US customs territory, directly freezing short-term export channels for some recyclers.

SMM believes this temporary export restriction is triggering chain reactions in the lithium battery recycling sector. In the short term, some recycling enterprises that rely on exporting black mass for cash flow face raw material backlogs and risks of defaulting on existing contracts, which may force them to cut capacity and adjust production. In the medium term, this move could accelerate the establishment of integrated capacity for black mass refining, precursors, and cathode materials in North America, pushing recyclers to sign long-term volume commitment agreements with refiners and battery manufacturers, thereby reshaping the logistics and business model of the US lithium battery recycling industry chain.

[SMM Energy Storage Battery Cell Market Weekly Review 8.06] Energy storage battery cell prices remain stable, with large-capacity products expected to accelerate shipments in H2

[SMM Analysis] This week, the energy storage battery cell market remained stable overall. The pullback in lithium chemical prices has not yet significantly transmitted to the battery cell side, and only some orders adopting a raw material linkage mechanism saw slight downward adjustments. The average price of 314 Ah battery cells remained around 0.365 Yuan/Wh. As the implementation details of the battery consumption tax have not yet been released, most battery cell enterprises have not yet uniformly raised prices. The additional tax costs may be shared through negotiation between upstream and downstream players in the industry chain. In terms of product structure, in H1, shipments of large-capacity battery cells above 500 Ah reached approximately 42 GWh, accounting for 8.6%. The market is still dominated by deliveries of 314 Ah products. As large battery cell capacity is gradually released in H2, the shipment share of these cells is expected to increase to around 15%.

The cobalt powder market remained weak this week, and actual transactions stayed thin.

The cobalt powder market remained weak this week, and actual transactions stayed thin. On the supply side, mainstream producers kept their offers within RMB 440,000‑460,000 per tonne, while some physical deal prices have dipped to RMB 430,000‑440,000 per tonne. More low‑price offers emerged among traders, further depressing market psychological price levels. Cobalt carbonate, the raw material, remained under price pressure. Some offers have fallen below RMB 200,000 per tonne. Market trading nearly stalled with no valid transaction references available. Downstream cemented carbide enterprises are constrained by end‑user orders, showing no acceleration in raw‑material consumption and maintaining slow purchasing rhythms. Apart from long‑term contract orders, spot‑deal volumes are relatively limited. In terms of market sentiment, most participants adopt a wait‑and‑see stance, generally believing that no notable market improvement will materialize in the short term.
