Two domestic distributors can still depend on the same fabrication or packaging route. The OECD's value-chain study helps electronics suppliers distinguish purchasing diversity from production resilience.
The OECD's June 2025 semiconductor value-chain study describes globally distributed production with tightly connected specialised stages. It identifies concentration in critical inputs, regional specialisation and trade dependencies, while also explaining important limits in the available data. The OECD study and public abstract
For defence electronics businesses, the immediate implication is that the country of the seller describes only part of the supply chain. Two suppliers in different countries can depend on the same upstream process. A domestic company can use several international production routes, while a foreign-owned facility may perform valuable local work.
The commercial question is therefore which production capability the product depends on, how difficult that capability would be to replace and what evidence supports an alternative.
The OECD separates semiconductor production into design, wafer fabrication, and assembly, test and packaging. Each stage relies on additional specialised inputs. Its discussion also explains that a company's degree of vertical integration can vary by product, making a single corporate label an incomplete description of the production route. The study's executive summary and value-chain definitions
That distinction matters when a commercial team describes a product as sourced domestically. Does the statement refer to the distributor, design company, fabrication site, packaging operation or final equipment assembly? Each is a different claim.
The useful response is a product-specific account. It need not expose proprietary manufacturing information publicly, but it should be sufficiently precise for the customer decision being made.
Consider a hypothetical electronics supplier buying a component through two authorised distributors. Both channels provide genuine stock and useful commercial support. However, they supply the same component from the same production route.
The second distributor can reduce dependence on one seller's inventory or service. It does not automatically create an independent manufacturing source. If the underlying component becomes unavailable, both channels may face the same constraint.
A similar issue can arise with apparently different components that share a critical upstream process. A company should avoid claiming complete independence merely because part numbers or supplier names differ.
This is why a resilience discussion should distinguish commercial channels, manufacturing routes and qualified substitutes. Each can reduce a different kind of exposure. Combining them into one supplier count makes the business appear easier to support than the evidence establishes.
An alternative component may look compatible in a catalogue while requiring changes to the customer's product, production checks or support documentation. Its commercial value depends on the work needed before it can be used.
For the hypothetical supplier, the relevant questions concern the affected equipment configuration, the evidence required for acceptance and the time needed to complete the change. The alternative may be technically promising but unavailable within the customer's required delivery period.
This does not mean every component change requires the same process. The product's requirements and contractual arrangements determine the relevant evidence. The point is to include that adoption work in the continuity plan rather than treating substitute discovery as the final step.
A supplier that has already documented and accepted an alternative route can offer a different level of continuity from one that has merely identified a possible replacement. Marketing language should preserve that distinction.
New facilities and equipment investments are relevant to supply-chain research, but their commercial meaning changes as the project advances.
Micross's December 2025 review described progress on its RESHAPE advanced-packaging project and identified further qualification and production-ramp work planned for 2026. The account distinguishes construction and equipment progress from later process and capability milestones. Micross's project review
The fuller BDI analysis of RESHAPE follows that sequence. The example concerns packaging capability, rather than a claim that a new wafer-fabrication plant has appeared.
For customers, the relevant question is when the required process becomes available for the relevant product. An installed tool, a qualified process and a production slot are connected milestones with different implications for delivery.
A procurement or sales forecast should reflect the milestone supported by the evidence. Announced investment can justify further supplier engagement without yet supporting an unconditional delivery promise.
A manufacturer may secure enough components for current deliveries while still facing a support challenge years later. Products with long service lives need a plan for repairs, replacements and eventual redesign.
Inventory can help, but its value depends on the component, storage requirements, traceability and the customer's actual repair demand. Holding a large quantity of the wrong configuration does not provide the same protection as maintaining usable, documented stock.
Another approach may be to redesign the product around an available component. That introduces engineering and acceptance costs, but it can reduce dependence on a discontinued part. The appropriate choice depends on expected demand and the product's remaining life.
The commercial comparison should include those costs explicitly. A low acquisition price may be attractive while leaving a large future redesign burden. A more expensive supported component may have a different lifetime cost.
A small electronics company cannot necessarily obtain complete information about every material and process in its supply network. A useful mapping exercise therefore begins with the dependencies that could materially affect its own deliveries.
Priority can follow the product's exposure: components with no accepted alternative, unusually long replacement work or a large share of the equipment's support risk. The company can then seek specific evidence from its suppliers rather than sending an undifferentiated questionnaire to everyone.
Information gaps should remain visible. An undisclosed fabrication route is not evidence of a particular country's involvement. It is an uncertainty to manage through the available contractual, technical and commercial arrangements.
The OECD's discussion of data limitations supports caution at the aggregate level. At company level, the same discipline prevents confident claims built on incomplete supplier declarations.
A supply chain can have available components but still struggle to deliver finished equipment if assembly, inspection or test capacity is constrained. This is why semiconductor mapping should connect to the customer's wider industrial process.
Our coverage of Thales's Netherlands test and production capacity examines the capacity needed around finished systems. The discussion of local production in German–Korean cooperation considers what work localisation actually retains.
Order demand belongs in a separate part of the picture. Hensoldt's backlog and delivery analysis shows why demand evidence should not be confused with output already achieved. The same separation is useful for electronic components.
A strong supply-chain account connects these layers: required inputs, accepted production processes, available capacity and the delivery commitments they support.
The most credible supplier statement is often specific. It might identify the production stages performed locally, the accepted alternative for a critical component or the support stock available for a defined equipment configuration.
That gives a buyer something to assess. A broad claim of sovereignty or resilience can obscure the remaining dependencies and create expectations the supplier cannot support.
The OECD's map provides a way to organise the investigation. The business value comes from applying it to an actual product and keeping the evidence current as suppliers, processes and configurations change. For electronics companies serving long-lived defence equipment, that knowledge can improve delivery confidence, support planning and the quality of the commercial promise.
