Relocation changes where a plant sits, usually at the final-assembly stage. Raw materials, refining, specialized equipment, process know-how and skilled labor can stay as concentrated as they were, and a new plant can still depend on all of them. Resilience is therefore a value-chain question: which step, material, machine, skill or transport route remains concentrated, and how quickly it could be replaced.
Why a new factory does not settle the risk
Three locations are easy to conflate, and most debates about reshoring blur them:

- Production location: where the plant physically runs.
- Company ownership: where the controlling firm is headquartered. A plant in one country can belong to a parent in another.
- Input origin: where the materials, components and equipment feeding the plant come from.
A supply chain can change on the first measure while staying concentrated on the other two. The table below sets out the seven questions that test a dependency at each stage, and why moving a factory answers none of them by itself.
Recommended Free Tools
| Axis | What to establish | Why relocating a factory does not settle it |
|---|---|---|
| Stage covered | Which step is at issue: mining, refining, equipment, components, packaging, final assembly or logistics | A move that relocates final assembly leaves the upstream steps where they were. |
| Concentration | Share held by the largest suppliers, facilities, countries and owners | A new plant may belong to a firm, or buy from upstream suppliers, in the same concentrated region. |
| Substitutability | Whether another qualified supplier can meet demand, and how long qualification and ramp-up take | A plant that exists on paper is not a replacement until a buyer has qualified its output. |
| Capability depth | Equipment access, process know-how, skilled labor, energy, water and supporting suppliers | These take longer to build than a building, and they are often the scarcest inputs. |
| Shock exposure | Export restrictions, transport chokepoints, natural hazards, cyber risks and domestic production shocks | Domestic plants face their own hazards. Relocation changes which shocks apply, not whether shocks apply. |
| Cost and spillovers | Resilience gains weighed against trade, productivity and price effects | Resilience is not free, and its costs fall on the wider economy as well as on the firm. |
| Visibility | Provenance and event data that expose dependencies without exposing commercially sensitive detail | A dependency that cannot be seen cannot be managed. |
Does reshoring make supply chains safer?
The OECD’s 2025 Supply Chain Resilience Review is the clearest evidence on this question, and its answer is no, not reliably. Its key points:
#1 Best Overall
- Concentration rose. The number of products sourced from a limited range of suppliers was 50% higher in the early 2020s than in the late 1990s.
- Modelled relocalisation policies could reduce global trade by over 18% and global real GDP by more than 5%. These are model outputs for broad policies, not forecasts for a particular country or measure.
- In that modelling, relocalisation did not consistently improve resilience, and GDP stability would fall in more than half of the economies analysed.
The OECD’s prescription is agile risk management and effective diversification, not retreat from international trade. Its Secretary-General, Mathias Cormann, said: “For trade to continue to provide the foundation of our shared prosperity, and to ensure trade delivers on our citizens expectations, we need to work together to enhance the reliability and resilience of our supply chains.”
Where dependence sits in clean-energy hardware
The IEA’s 2026 clean-energy assessment shows how concentrated manufacturing capacity remains in two technology chains. The figures below are China’s share of supply-chain production capacity:
| Technology chain | Stage | China’s share of capacity (IEA, 2026) |
|---|---|---|
| Solar | Whole supply chain | Around 85% |
| Solar | PV wafers | 95% |
| Lithium-ion batteries | Whole supply chain | Around 80% |
| Lithium-ion batteries | Anode materials | 97% |
These figures describe manufacturing capacity. The manufacturing-stage measure excludes resource extraction, so they do not measure mining output.

The IEA’s Energy Technology Perspectives 2026 models an N-1 scenario, removing the largest exporter from the picture. In 2024, outside-China capacity could theoretically meet most non-Chinese demand at the final stages of several reviewed technologies. The gap sits upstream. Intermediate steps are less covered, and in each chain at least one step covers less than one-quarter of demand.
This is a capacity-against-demand calculation, not a tested reroute. It shows where a shortfall would appear on paper, which is the information a buyer needs to decide where to qualify a second source.
Critical minerals and export controls
The IEA’s Global Critical Minerals Outlook 2026 reports that critical-mineral prices rebounded in 2025 and early 2026 amid tighter supply. Strategic minor-mineral prices more than doubled, and tungsten prices rose sixfold. The IEA treats export controls and concentrated processing as immediate economic-security risks.
The report also puts dollar values on two disruption scenarios. Both are conditional exposure figures, not realized losses or forecasts:
| Scenario (IEA, 2026) | Downstream production outside China at risk | Condition attached |
|---|---|---|
| Full disruption of battery-grade graphite trade | Over USD 300 billion per year | Applies only if the full trade disruption occurs |
| Full implementation of expanded rare-earth export controls | USD 6.5 trillion per year | Applies only if the expanded controls are fully implemented |
What the rare-earth suspension does and does not settle
The IEA reports that the expanded rare-earth restrictions, announced in October 2025, were suspended for one year, until November 2026. While the suspension holds, the USD 6.5 trillion scenario describes a contingency, not a current loss. The report does not establish what happens when the suspension ends, so that question remains open. The expiry falls within weeks of this article, so check the current notices from the issuing authority before drawing conclusions from the date.
Why moving a downstream plant does not secure its inputs
The IEA’s examples explain why. Graphite, rare-earth processing technology, specialized equipment and technical expertise can all stay concentrated while the factory that uses them moves. A battery plant built outside China can still depend on the same graphite and anode-material base, and a plant that uses equipment from a narrow supplier pool inherits that pool.
Rank #4
Semiconductors: diversification is a capability problem
The U.S. Department of Commerce’s 2021–2024 review of semiconductor supply chains says CHIPS Act initiatives redirected investment. It also finds that some manufacturing capacity remained regionally concentrated or was becoming more concentrated. The review names mature-node semiconductors and conventional packaging as diversification priorities, and it flags continued risks from critical inputs, workforce needs, natural hazards and emerging technologies.
The review says private-sector commitments for new U.S. semiconductor production exceeded USD 446 billion over the period it covers. A commitment is not operating capacity. The figure does not show that every stage has been diversified, and the priority list shows where the review saw diversification still to be done.
Capabilities decide whether a second source is real
Diversification requires capabilities as well as new factories. The IEA points to gaps in technology, specialized equipment and skilled workers in refining and processing. Commerce’s review likewise treats workforce needs as a constraint on its manufacturing goals. A second source counts only when a buyer has qualified its output, which takes time, and when the plant can run at the required scale. Before treating a new source as a replacement, check:
- Equipment: whether the specialized tools, and the parts and service for them, are available outside the concentrated region.
- Process know-how: whether the process has run at the required volume, not only in design or pilot form.
- Skilled labor: whether trained staff exist locally, or must be recruited from elsewhere.
- Supporting suppliers and utilities: energy, water and the sub-tier inputs the plant needs to keep running.
- Qualification and ramp-up: how long the buyer’s approval process and the plant’s ramp-up take, and what covers demand while both are underway.
Traceability shows the map, not the spare capacity
NIST IR 8536, finalized on 9 September 2026, proposes a manufacturing traceability meta-framework and includes an open-source Python reference implementation. It links supply-chain event data into a temporally ordered provenance chain, uses cryptographically verifiable links, and supports selective disclosure, so a firm can share proof about a record without exposing the proprietary details behind it. The framework is intended to support verification and risk management.
Traceability reveals dependencies; it does not remove them. If a component passes through one smelter, traceability makes that visible. It does not produce a second smelter, a qualified alternative or an emergency plan.
What traceability can and cannot do
- It can show which tier, facility and country each input passed through, and where single-source points sit.
- It can produce verifiable provenance records that are shared selectively.
- It cannot qualify a substitute supplier, create spare capacity or write an emergency plan.
- It cannot show that a supply chain is resilient. The NIST publication describes the framework; it is not evidence that any particular company has adopted it.

- Geographic coverage relative to where your suppliers operate.
- Customer fit and partner terms.
A practical sequence for mapping dependence
- Map each product from raw material through final assembly, including the logistics links between stages.
- Mark every stage where one supplier, facility, country or owner holds most of the volume, and record the owner as well as the location.
- For each marked stage, estimate how long a qualified replacement would take, and what would cover demand in the meantime.
- Apply the capability checks from the second-source list above to each marked stage.
- Record provenance events for the marked stages, using the traceability approach described above.
- For each marked stage, decide whether to diversify, hold reserve capacity or accept the exposure, weighing the cost and spillover effects of each choice.
