Brussels: A draft regulation circulating among Commission services would oblige European companies in selected strategic sectors to source critical components from at least three different suppliers, with a stipulation that no single supplier may originate in China. The proposal, first reported on 18 May, signals a shift in the bloc’s economic-security toolkit from declaratory de-risking to mandated diversification, and its implications go well beyond the chemicals and industrial-machinery sectors named in initial briefings.
The intellectual lineage of the rule is unmistakable. Commission economists have spent the past three years constructing a typology of strategic dependencies, identifying components and inputs where European industry relies on a small number of overseas suppliers, typically concentrated in China. Internal mapping exercises have repeatedly flagged dozens of inputs ranging from rare-earth permanent magnets to specialty intermediates in active pharmaceutical ingredients, where Chinese producers control more than 70 percent of global capacity. The three-supplier rule is the first concrete instrument designed to force corporate procurement teams to act on those findings rather than treat them as risk-register entries.
The mechanism is deceptively simple. Companies operating within designated sectors would be required to demonstrate, on a rolling basis, that they have qualified alternative suppliers outside the dominant geography. The burden of proof is procedural rather than transactional, which is significant. A company need not necessarily buy from each of the three suppliers, but it must maintain the ability to switch within a defined window. This design borrows heavily from the qualified-supplier regimes that have long governed defense procurement, where the existence of redundancy matters more than the daily allocation of orders.
The economic logic is contested. Critics within European industry argue that mandated supplier diversity will raise unit costs, particularly in sectors where Chinese producers benefit from genuine economies of scale rather than subsidies. The Commission’s response is that the cost of resilience must be measured against the cost of disruption, and that the experience of the past five years, from semiconductor shortages to the pharmaceutical-precursor squeeze during the pandemic, justifies a precautionary approach. The deeper question is whether a regulatory mandate is the appropriate instrument, or whether tax credits, contingent stockpiling, and direct subsidies to alternative suppliers would deliver comparable resilience at lower market distortion.
Geopolitical considerations cut both ways. Beijing has consistently characterized European de-risking measures as disguised decoupling, and a binding rule against single-source dependence on Chinese suppliers will sharpen that critique. At the same time, the architecture of the proposal allows the Commission to argue that it is content-neutral with respect to nationality. The rule applies to dominant single sources wherever located. That formal neutrality is unlikely to convince Chinese policymakers, but it provides a defensible position in the World Trade Organization dispute that many trade lawyers consider inevitable.
The proposal also tests the limits of the Single Market. Procurement is largely a corporate function, and member states have historically resisted Commission intrusion into how private firms manage their supply bases. The legal basis under consideration is Article 114 of the Treaty, harmonization for the functioning of the internal market, which has proved expansive but is not unlimited. Whether the Court of Justice would uphold a procurement mandate as a market-functioning measure rather than an industrial policy in disguise remains an open question.
For European industry, the most immediate task is mapping. Few large manufacturers maintain a comprehensive view of their tier-two and tier-three suppliers, and the rule would force precisely that exercise. Several consultancies report a surge in inquiries from boardrooms seeking to understand their exposure ahead of any formal text. The Commission has not confirmed a publication date, but the political momentum suggests that a proposal will reach the College before the summer recess, with member-state consultations beginning soon after.
