Sources: Germany is in talks to limit the export of chemicals used to make advanced chips to China, seeking to join US and EU allies in closing ranks on China
Germany is in talks to limit the export of chemicals to China that are used to manufacture semiconductors as Berlin steps up efforts …
Context & Ripple Effects
Berlin's reported talks extend a control regime that began with machines: after the Netherlands and Japan agreed in principle to join the US in December 2022, Washington secured the formal agreement restricting advanced chipmaking machinery in January 2023 (restricting exports of advanced chipmaking machinery). Chemicals are a different layer of the supply chain — consumables rather than capital equipment — so German participation would close one of the remaining input channels outside that machinery perimeter.
The move also lands under sustained US pressure on allies: sources reported the US pressing the Netherlands, Germany, South Korea, and Japan to tighten rules further (US pressure on Germany and other allies), and later Trump's team meeting Dutch and Japanese counterparts to urge more restrictions (Trump team's tougher curbs push). For Berlin, chemicals are where its own industrial base gives it leverage no other ally has.
First-order effects
- Chinese chipmakers would lose or face delays on German-sourced process chemicals used in advanced-node fabrication, forcing qualification of alternative suppliers mid-production.
- German chemical producers with semiconductor-grade product lines would see their largest growth market constrained by their own government's policy, not by demand.
Second-order effects
- China's substitution push intensifies along the same lines already visible in its undocumented requirement that new capacity use at least 50% domestically made equipment — chemical self-sufficiency becomes the next procurement mandate, backed by the state VC funds Beijing has launched for early-stage hard-tech.
- Allied suppliers outside the US-Japan-Netherlands core face a choice between complying with an expanding perimeter and serving China through non-aligned channels — the exact substitution dynamic the controls are meant to prevent but cannot fully stop.
Third-order effects
- If the pattern holds, export controls keep migrating from headline equipment (lithography) down the bill of materials — gases, chemicals, materials — making the effective choke point the full input stack rather than any single tool, and raising compliance costs across every allied supplier.
- China's countermeasures — domestic-equipment quotas, hard-tech venture funds, and workarounds like retrofitting older DUV tools — point toward two partially decoupled chemical-and-materials supply chains, with third-country producers arbitraging the gap.
The trend: Chip export controls are expanding from advanced lithography equipment down into process chemicals and materials, with each allied government's participation defining how complete the closure is.
