The European Commission is weighing legislation that could require companies in sensitive sectors to reduce reliance on single suppliers, with China-dominated supply chains firmly in view.
The proposal is being considered as part of a broader review of the EU’s trade defence and economic security tools. European Trade Commissioner Maroš Šefčovič has indicated that high-risk sectors may need a dedicated instrument to move away from single-supplier dependence, with companies potentially required to diversify sourcing across at least three suppliers or routes.
The sectoral scope has not been finalised, although the discussion is expected to focus on strategically important inputs such as critical minerals, industrial components, chemicals, semiconductors, batteries, clean-energy technologies, and other areas where excessive dependence on one country or supplier creates economic security risk.
The measure would mark a more interventionist approach to supply-chain resilience. Diversification has long been encouraged through guidance, industrial strategy, and procurement discipline. A binding instrument would push the issue deeper into corporate sourcing, risk management, and supplier qualification processes, turning supply concentration into a compliance issue as well as a commercial judgement.
Europe’s concern has sharpened as trade tensions, export restrictions, and industrial overcapacity expose weaknesses in supply chains built primarily around efficiency and cost. Critical minerals are a clear example. Many clean-energy, automotive, defence, electronics, and industrial technologies depend on materials where mining, processing, or refining capacity is concentrated in a small number of countries. A disruption in one part of that chain can quickly affect factories that appear, on paper, to be geographically diversified.
Similar sourcing pressure is already visible in trade compliance, where forced-labour tariff proposals have increased scrutiny of supplier origin and due diligence. The Commission’s proposal points in the same direction from the European side: supply-chain resilience is becoming part of formal industrial governance rather than a discretionary procurement preference.
The practical burden would be significant. Multi-sourcing sounds simple, but qualifying additional suppliers can take months or years in regulated or technically demanding sectors. Automotive, aerospace, medical, pharmaceutical, electronics, and process-industry supply chains cannot swap suppliers casually. Components may need validation, process audits, documentation, testing, tooling adjustments, customer approvals, and long-term quality evidence before they can be used.
The proposal could also create a capacity problem. If many companies are required to diversify away from the same high-risk sources at the same time, alternative suppliers may not be ready. New capacity in mining, refining, semiconductor materials, battery components, and specialist industrial inputs requires capital, permitting, skills, and long construction cycles. Regulation can create demand for diversification faster than the market can create credible substitutes.
The direction is unlikely to disappear. The pandemic, energy shock, shipping disruption, and recent trade disputes have changed the assumptions behind global manufacturing. Low-cost supply chains built around narrow sourcing routes can be efficient until disruption turns a small dependency into a production stoppage. Missing components, delayed output, and emergency logistics can wipe out years of procurement savings.
The EU is also looking at faster anti-dumping and anti-subsidy processes, alongside potential measures to address overcapacity. Supply dependence is not only about disruption. It is also about market structure. If subsidised overcapacity drives European suppliers out of business, the region becomes more dependent on imports even when no immediate shortage exists. Resilience therefore depends on both access to materials and the survival of domestic or allied production capability.
The Commission will have to balance ambition with workability. A rigid diversification rule could create administrative burden, increase costs, and penalise companies in sectors where alternatives are not yet available. A weak rule would simply restate existing risk-management advice. Transition periods, sector exemptions, evidence thresholds, and the measurement of dependence across complex bills of materials are likely to become central points of negotiation.
Supplier concentration is heading for greater scrutiny. Procurement strategies built around price, delivery, and quality will increasingly need to show resilience, traceability, geopolitical awareness, and credible contingency routes. The EU’s proposal suggests that global availability is no longer enough as an assumption of supply security. Critical inputs will need stronger proof of continuity when politics, trade rules, or export controls turn against the old sourcing model.
