Businesses can assess exposure by tracing critical materials from the components they buy back through suppliers, processing and recycling; measuring concentration, geopolitical and trade risks, import dependence, substitutability and operational impact; and turning the findings into disruption scenarios with named mitigation owners. The assessment is useful only if it shows both what is known and where supply-chain visibility ends.
What a raw-material disruption assessment should tell you
A useful assessment answers three linked questions: which materials could interrupt your business, where and how could their supply fail, and what can you do before a shortage affects production or service delivery? It is not just a list of minerals or countries of origin. A material may be mined in one country, refined in another, incorporated into a component elsewhere and bought from a direct supplier that cannot identify the upstream processors. Risk at any of those stages can matter.
The assessment should connect each material to the product, component, process or obligation that depends on it. It should also distinguish supply risk from responsible-sourcing risk. A shortage analysis asks whether a business can obtain the material in time and in the required quantity and specification. Due diligence asks whether sourcing is associated with adverse impacts and what the company must do to address them. The two can use some of the same supplier and origin information, but neither replaces the other.

Start with consequences, not a generic list of minerals
Begin with products, services and processes whose interruption would materially affect output, revenue, safety, customer commitments or legal obligations. Work from the bill of materials and component specifications, including materials embedded in finished components that your company does not purchase as raw inputs. Include indirect materials where their absence could stop an important process. A list of materials labelled “critical” at national or regional level can help focus attention, but it does not by itself show which materials are critical to your own operations.
For every material and affected component, record the units consumed, spend, current inventory coverage, replenishment lead time, time needed to qualify another supplier or material, and the consequence of a shortage. Capture dependencies: one unavailable material may affect several components, products or sites. Conversely, a material with high spend may have little operational impact if it is easy to replace and stocked in sufficient quantities.
Trace the chain as far upstream as evidence permits
Link the material to its direct supplier and then to known upstream actors and stages. Record extraction, processing or refining, recycling, trading or transport points where known. For each data point, keep its source and date. Mark whether it is verified, reported by a supplier, inferred from another source or unknown. Do not convert an unknown origin into a presumed low-risk origin.
The International Energy Agency (IEA) describes traceability as following a material’s origin, movement, custody and transformation. In practice, visibility commonly weakens beyond direct suppliers. In 2026, the IEA reported results from an IEA–OECD survey of more than 80 companies active in critical-mineral supply chains: two-thirds had some form of traceability system, with 30% reporting full coverage and 40% coverage of selected minerals or supply chains. These are survey findings about respondent companies, not a target that every business can reach or a measure of any one company’s exposure. They also show why “we have a traceability system” is not enough: define which materials, volumes, tiers and stages it actually covers.

Keep coverage and confidence separate
A company may know a supplier’s identity but not the mine or refinery behind a component. It may have a country-level origin estimate without verified chain-of-custody information. Record coverage separately from confidence so that an incomplete but reliable data point is not confused with broad, weakly supported coverage.
| Record for each material | What to capture |
|---|---|
| Business dependency | Products, components, sites and processes affected; volume or units used; shortage consequence. |
| Supply chain | Direct supplier and known upstream actors; extraction, processing, recycling and trade or transport locations where available. |
| Continuity | Inventory coverage, lead time, supplier recovery information, alternative-source qualification time and available substitutes. |
| Evidence quality | Origin and stage covered, volume covered, number of visible tiers, source, date and whether information is verified, supplier-reported, inferred or unknown. |
| Response | Relevant disruption scenarios, business impacts, mitigation actions, accountable owners and review dates. |
Assess exposure across the whole supply route
Compare materials and supply routes on several dimensions. Assess them by stage, not only by mine location: a supply route with multiple extraction sources may still depend on a concentrated refining stage. The European Environment Agency (EEA) methodology for EU critical raw-material supply risk considers concentration, supplier-country governance, import reliance, trade issues, recycling and substitution. These are useful dimensions for a company assessment, although the EEA’s regional indicator is not a company risk score.
| Exposure dimension | Questions for the assessment |
|---|---|
| Concentration | How many suppliers, countries and processing locations supply the material? What share of the company’s volume depends on each? Is concentration greater at a particular stage? |
| Geopolitical, governance and trade conditions | Could instability, governance concerns, export controls, trade restrictions or a chokepoint impede supply? Which stages and routes are exposed? |
| Import dependence and alternatives | How dependent is the route on imported supply? How quickly could another source be qualified? Would a substitute meet performance, quality and operational requirements? |
| Recycling and recovery | Is secondary material available in the required quantity and specification? What recovery options exist, and can the company use recycled inputs? |
| Operational consequence | How soon would an interruption affect the business? How much inventory is available, how long might supplier recovery take, and what are the financial, customer, safety or other impacts? |
| Traceability confidence | What share of volume has known origin and processing? How many tiers are visible, how strong is the verification and how old is the information? |
Trade exposure is not hypothetical in the abstract: the IEA reported in 2026 that export controls had threatened mineral supplies in 2025. That observation does not identify every affected company or predict a future restriction. It does make trade policy and export controls relevant scenario inputs, alongside supplier failure, processing outages and logistics interruptions.
Regional indicators can provide context, not a substitute for company analysis. The EEA’s EU indicator, based on the Joint Research Centre’s Critical Raw Materials Dashboard and triennial assessments, compares supply-risk changes for 66 raw materials from 2011 to 2023. Its summary reports increased risk for 36 materials, steady risk for five and decreased risk for 25. This is an EU-level comparison through 2023, not a forecast or a measurement of an individual company’s exposure. The EEA says the assessment is repeated every three years.
Turn data into scenarios and priorities
Make assumptions visible
Use a transparent method that separates likelihood from impact. The cited frameworks do not prescribe a universal company scoring formula, set of weights or threshold. Define any scales internally, explain what each rating means, and show which evidence supports it. Keep missing information visible as uncertainty or a data gap rather than assigning it a low-risk rating. A numerical score should help decision-makers compare and act; it should not conceal weak evidence behind apparent precision.
For each material, ask what happens if a major source country becomes unavailable, a processing site stops operating, an export restriction blocks trade, a transport route is interrupted or a supplier fails. Trace the consequence to the affected component, site, process and customer or business commitment. Consider how long current inventory would last and whether the interruption would outlast it. Use supplier recovery information where available, but label estimates and assumptions clearly.
Prioritise by business impact and fragility together
Give attention first to materials that combine serious operational consequences with concentrated or fragile supply and few feasible alternatives. A highly concentrated route may be manageable if the business can switch quickly to qualified substitutes; a less concentrated route may still be critical if a stoppage would immediately halt a key process. Prioritisation should therefore consider both how vulnerable the route is and how much the company depends on it.
A practical record for each priority material can state the scenario, affected component or process, estimated time to impact, evidence and assumptions, current controls, residual exposure, and the action required. This creates a traceable link from a supply-chain fact to a business decision, instead of producing a risk register detached from procurement and operations.
Choose mitigation that fits the vulnerability
Match the response to the source of risk and the company’s ability to act. The European Commission’s proposal text dated 3 December 2025 identifies diversification of strategic raw-material supply chains, consideration of secondary raw materials and substitution as mitigation efforts where significant vulnerabilities are detected. Businesses may also assess whether inventory buffers or contractual arrangements are justified. Any option involves trade-offs in cost, qualification time, quality, performance and responsible-sourcing effects; a nominal alternative is not useful if it cannot be approved or supplied at the needed scale.
- Diversify supply: qualify suppliers or routes that reduce dependence on a concentrated source or stage. Check whether apparently separate suppliers rely on the same upstream processor.
- Increase secondary-material use: assess availability, required specifications, recovery options and the ability to incorporate recycled inputs into the relevant component or process.
- Substitute or redesign: test whether another material or design can meet functional, quality and safety requirements, and account for the time and approvals needed to implement the change.
- Improve visibility: ask suppliers for material, origin and processing information, with coverage and evidence expectations appropriate to the risk. Focus effort on important gaps rather than treating data collection as the end goal.
- Consider buffers and contracts: evaluate inventory or contractual measures against interruption duration, carrying cost, lead time and the risk that multiple suppliers share the same upstream vulnerability.
Assign each action an owner, milestone and review date, and record the residual risk after the action. A mitigation is not complete merely because it appears in a plan: the company needs to know whether the alternate source was qualified, whether recycled material is available, or whether the new evidence actually closes a visibility gap.

Present significant exposures, scenarios, assumptions, data gaps and mitigation owners to senior leadership or the board. The purpose is to make trade-offs and accountability explicit: leaders may need to approve redesign work, supplier qualification, inventory investment or a decision to accept residual exposure. Reassess after meaningful changes in sourcing, supplier structure, trade policy, product design or market conditions, rather than relying on a static map.
The European Commission’s COM(2025) 946, dated 3 December 2025, is a proposal to amend Regulation (EU) 2024/1252. Its text describes assessment provisions for identified large companies operating in the Union that use strategic raw materials in specified sectors. The proposal describes mapping components containing those materials and the stages where they are extracted, processed or recycled; assessing supply factors and vulnerabilities; and making efforts to mitigate significant vulnerabilities. It also describes board presentation and an assessment cadence of at least every three years, with an initial assessment within six months of identification, to the extent required information is available.

Those are provisions in proposal text, not a blanket statement of current legal duties for all businesses. The scope is limited as described in the proposal, and its legislative status and final text should be checked before a company treats those provisions as an enacted obligation. Businesses outside that described scope may still use the workflow as a voluntary continuity-management practice.
Keep physical supply risk distinct from responsible-sourcing duties
EU Regulation (EU) 2017/821 establishes specific due-diligence obligations for covered Union importers of tin, tantalum, tungsten and gold (3TG) originating from conflict-affected and high-risk areas. Article 5 includes risk-assessment and risk-management requirements. The regulation is not a general physical-shortage assessment requirement for every business or every mineral. Its response approach includes continued trade with measurable mitigation, temporary suspension while mitigating, or disengagement after mitigation has failed; applicability and the current consolidated law should be checked with qualified counsel.
The European Commission’s “Due diligence ready!” portal provides mineral-risk guidance and OECD-based tools that can help small and medium-sized enterprises and other companies with responsible-sourcing due diligence. Such guidance can complement a continuity assessment by strengthening supplier and origin information, but the company should preserve the distinction between assessing adverse sourcing impacts and assessing whether material will be available when needed.
Quick Recap
A workable first-pass checklist
- Choose the scope: identify products, processes, components and materials whose interruption could materially affect the business.
- Connect dependency to supply: link each material to its component and direct supplier, then map known extraction, processing, recycling and trade stages.
- Mark evidence limits: record volume coverage, visible tiers, sources, dates and whether information is verified, reported, inferred or unknown.
- Compare exposure: examine concentration, country and trade conditions, import reliance, alternatives, circularity, operational consequences and traceability confidence.
- Run relevant scenarios: test plausible source-country, processing, trade, logistics and supplier disruptions against inventory, recovery time and business impact.
- Prioritise and act: select mitigations for the most consequential vulnerabilities, assign owners and dates, and track whether actions change the exposure.
- Review and govern: bring material findings and unresolved assumptions to leadership, then refresh the assessment when supply or business conditions change.
