The article examines the role of smaller open economies in global mining and critical raw materials value chains. Its central argument is that mining value chains may be global in reach, but their actual performance depends on the depth of regional industrial capability. Using Estonian company cases, the article analyses three pathways into mining-related value chains: digital intelligence, certified engineering capability and knowledge infrastructure. The cases show that smaller firms do not need to compete through scale. Instead, they can create significant value at narrow, but strategically critical niche interfaces. Particular attention is given to the role of documentation, certification, compliance and trust, through which hidden champions can become visible, credible and integrable partners in international industrial value chains. The article is based on the author’s presentation at the “MiningForum 2026”, held in Berlin/­ Germany from 18th to 19th June 2026.

Raw materials have moved from the periphery of industrial policy to its center. Across Europe, political attention, investor interest, and regulatory architecture are converging on a single proposition that resource security is no longer a background condition of industrial competitiveness, but a frontline concern of it. The European Union's Critical Raw Materials Act (European Commission, 2024), the tightening of export controls by major producing nations, and the visible reorganization of long-standing supply relationships have together produced what conference programming now calls, with some justice, a raw materials momentum.

Momentum, however, is not the same as delivery. The translation of political urgency into industrial outcome requires more than capital and regulation. It requires permits that lead to investment decisions, construction that becomes production, and, the subject of this article, supply relationships that can actually be built. A critical raw materials strategy is, in the end, only as strong as the supplier base that can execute it. This article asks a narrower, but more tractable question than the macro-level resilience debate: what determines whether a smaller, capable economy can become a contributing part of that supplier base at all, and at what tier?

The argument developed here is that mining value chains, while global in their reach and coordination, remain regional in the depth of capability that allows any given supplier to participate in them. This is not a new claim within global value chain (GVC) theory, which has long distinguished between chain governance, who coordinates, who sets standards, who absorbs risk, and chain participation, which depends on the capability a supplier brings to a specific functional position in the chain (Gereffi, Humphrey and Sturgeon, 2005). What this article contributes is an empirical account of how that participation actually happens for a class of supplier that existing GVC research has largely bypassed. The GVC literature on mining concentrates on resource rich developing economies and multinational lead firms (Morris, Kaplinsky and Kaplan, 2012; Fessehaie, 2012), while work on how smaller economies participate in global production has largely proceeded through aggregate value-added decomposition (Timmer et al., 2014) rather than through the firm-level mechanisms of entry. Smaller, EU compliant economies entering mining adjacent chains through capability transfer rather than extractive endowment sit in a gap between these streams.

The empirical material is drawn from four Estonian companies operating at different points adjacent to the mining value chain: Proekspert and its sensing subsidiary Sensorise (industrial AI and IoT), Eesti Kraanavabrik – EKV Cranes (precision crane engineering), Estanc (process equipment originally built for oil and gas), and Regio (geographic information systems (GIS) and legacy data digitization). None of these firms began as mining suppliers. All have, in the past several years, found defensible positions inside or adjacent to mining and mining-equipment value chains. Their routes into that position differ, but they cluster around three pathways, which structure the remainder of this article: digital intelligence, certified engineering capability, and knowledge infrastructure.

Global value chain theory offers a useful starting point but an incomplete one for the question this article asks. The standard GVC governance typology – market, modular, relational, captive, and hierarchical chain forms – builds on Gereffi’s earlier distinction between buyer-driven and producer-driven commodity chains (7), and explains how lead firms coordinate suppliers once a relationship exists (8). It says comparatively little about how a previously unconnected regional supplier becomes visible to a lead firm in the first place, and on what basis a lead firm decides that a new supplier is trustworthy enough to admit into the chain at all. This article treats that admission problem, call it the legibility problem, as analytically distinct from, and prior to, the governance problem.

2.1 Capability as a precondition, not a guarantee

Sturgeon’s account of modular production networks shows that lead firms can engage unfamiliar suppliers where interfaces are codified and standardized, reducing the need for relationship-specific coordination (17). This article builds on that insight, but treats industrial capability itself as a necessary but not sufficient condition for chain entry. A firm may possess the technical competence to perform a function within a value chain and still fail to enter it, because capability alone does not communicate itself across institutional and geographic distance. What is required in addition is a mechanism by which capability becomes legible, recognizable, verifiable, and low-risk, to a lead firm operating under its own compliance and liability constraints.

2.2 The “Bau-Turbo” parallel

A useful parallel comes from outside the mining sector. Germany’s Act to Accelerate Residential Construction and Ensure the Provision of Housing [1], in force since October 2025 and known after its central provision, section 246e of the Federal Building Code, as the “Bau-Turbo”, responds to an acute delivery shortfall in housing. What is instructive is where the legislature located the constraint. It did not act on the supply of builders, land, or capital. It acted on the approval procedure, allowing qualifying projects to proceed without the individually negotiated planning process each project had previously required. The diagnosis was that delivery was being throttled not by a shortage of capacity but by the transaction cost of verifying each project on its own terms.

The same logic, this article argues, applies to mining-related procurement. The binding constraint on faster, more resilient supply chains is not supplier quantity but supplier legibility: the ease with which a lead firm can verify that a new supplier meets its technical, regulatory, and quality requirements without bespoke due diligence. Where the Bau-Turbo reduces that verification cost by statute, harmonized certification reduces it by standard, and with the same effect on the speed at which new participants can be admitted. The two mechanisms differ in kind rather than degree: the Bau-Turbo removes the individualized check itself, substituting statutory qualification for case-by-case review, whereas certification does not remove the check but pre-pays it, converting a cost that would otherwise be borne anew in each transaction into a one-time investment that can be verified once and reused indefinitely. Both lower the marginal cost of admitting a  new participant, but by different routes, deregulation in one case, standardization in the other, a distinction the analysis below treats as significant.

2.3 Documentation as deliverable, not overhead 

This reframes a category that GVC literature has traditionally treated as a transaction cost: documentation, certification, and compliance reporting. Where conventional analysis treats these as overhead that suppliers must absorb to participate in a chain, the cases below suggest a stronger claim: for a certain class of regional supplier, the documentation is part of the product. A pressure vessel that ships with a complete PED (Pressure Equipment Directive) certification trail is not merely a compliant vessel; it is a vessel whose compliance has already been verified by a third party the buyer trusts, which materially reduces the buyer’s own integration risk. The same logic extends to GIS data that ships in formats already compatible with the buyer’s planning software, or to embedded software that is built to the same functional safety standards the buyer’s own systems use. In each case, the supplier is not merely meeting a requirement; it is supplying the buyer’s risk-reduction infrastructure as part of the transaction.
