Washington's Scrap Ban Just Handed Beijing a New Lever — and Tungsten Is the Fuse

When the United States published its new export restriction on tungsten scrap and battery-recycling feedstocks on August 5, the move was framed domestically as a supply-chain sovereignty play under the Defense Production Act. But in Beijing's trade ministry, the reaction may have been closer to satisfaction. China processes roughly 60–70% of the world's primary tungsten — and the US move cuts off the secondary supply channel that the West has been building precisely to reduce that dependency. Less than a week after Washington signed the executive order, China now has both a structural argument and a mirror to raise.

The mechanism of the US ban is straightforward but consequential. The Federal Register rule, issued under the Defense Production Act, requires US vendors of tungsten scrap and "black mass" — the crushed material from end-of-life lithium-ion batteries containing cobalt, lithium, and nickel — to prioritize domestic sales. Exports are banned for one year; exemptions are available but not guaranteed. The stated goal is to keep critical mineral inputs inside the US industrial base rather than shipping them to Chinese processors who then sell finished products back at higher margins.

Why the Timing Is Not Coincidental — and Why China's Stocks Moved First

The ban was published on August 5 — the same afternoon Beijing rolled out its own trade actions targeting the United States (Announcements No. 33 and 34 on drone exports and the first-ever trade security probe). But the tungsten move had been telegraphed for days: the executive order authorizing the policy was signed by President Trump less than a week earlier. Markets, however, had already priced in the direction of travel. A-share tungsten stocks surged hard on August 5: Zhongwu Gaoxin hit the 10% daily limit, Xiamen Tungsten climbed 8.79%, and the entire small-metals sector rose 6.23%.

The logic is counterintuitive to anyone outside the metals trade. A US export ban on scrap sounds like bad news for Chinese processors — they lose feedstock. But the market read it differently: if the US is willing to constrain its own recycling economy to reduce Chinese dependence, it confirms that Chinese tungsten processing is genuinely irreplaceable. And the supply crunch inside the US will push domestic tungsten prices even higher, which is a direct margin tailwind for Chinese producers selling into the spot market.

Why this matters for your sourcing desk: China is both the world's dominant tungsten processor and a significant scrap importer. If secondary supply chains are disrupted by US policy, pressure on primary ore demand rises. Buyers of tungsten carbide, tungsten heavy alloy, tungsten powder, and tungsten wire — especially those sourcing from Chinese mills — should expect price confirmation on fresh contracts before quarter-end. This is not theoretical: the A-share market moved on the signal before the physical market adjusted.

The Mirror Beijing Can Raise — And What It Already Controls

Tungsten is not a random commodity pick. It is used in cemented carbide cutting tools for semiconductor manufacturing equipment, in heavy alloy components for aerospace and defense, in lamp filaments, and in radiation shielding. China has already demonstrated willingness to use export controls on medium and heavy rare earths, gallium, germanium, and graphite — and most recently on helium. Tungsten processing technology and know-how sit squarely in that same toolkit.

What makes the current moment different is the simultaneous tension in two other supply chains relevant to this discussion. In DRAM chips, Apple attempted to negotiate lower prices from Changxin Memory Technology (CXMT) — China's domestic DRAM champion — and was reportedly rebuffed, with CXMT insisting its pricing would not fall below Samsung or SK Hynix levels. Standard DRAM contract prices surged 55–60% in early 2026, and DDR5 16G spot prices climbed 627% over twelve months to May 2026. CXMT has the leverage to hold that line. Meanwhile, US prices for tungsten scrap have already tripled year-on-year before the new export ban takes full effect — a figure that should appear in every buyer's cost model.

Two Trade Flashpoints, One Common Thread

The common thread is leverage inversion. In critical minerals, Beijing controls the upstream; in advanced manufacturing, CXMT is proving it controls pricing floor; in trade policy, the August 5 drone and security-probe announcements show Beijing is now willing to use previously dormant legal instruments. The era of Chinese exporters accepting price concessions as the default is being renegotiated across multiple fronts simultaneously.

Your Action List

Supply chain policy is now moving faster than commercial negotiation cycles. The US export ban on tungsten scrap and the CXMT DRAM price standoff are not isolated events — they are data points in the same structural story: a reorganisation of who controls critical mineral and advanced manufacturing inputs, and who pays the price for that transition. The exporters and buyers who treat policy as a line item — not an exception — are the ones who will have inventory when others are still waiting for their licence.
