Responsibility can exist at more than one level
A component manufacturer and a final product manufacturer can both be relevant when a defective part makes a finished product unsafe. Article 8 of Directive (EU) 2024/2853 does not require choosing one automatically. It addresses the manufacturer of the defective product and, under specified conditions, the manufacturer of a defective component. The inquiry must establish the applicable role and liability conditions for each actor.
The component and supply-chain liability overview sets out the broader framework. This comparison focuses on allocating responsibility between the component producer and the organisation responsible for the assembled product. A supply contract may help identify what each agreed to do, but a contractual label such as supplier or customer does not conclusively determine their statutory roles or the cause of the defect.
Identify what each manufacturer actually produced
Article 4's manufacturer definition includes developing, manufacturing or producing a product, having it designed or manufactured, presenting oneself as manufacturer through branding, and producing for one's own use. A final product manufacturer may therefore outsource substantial production without ceasing to have a relevant role. Equally, a company supplying an item may be a distributor rather than its manufacturer.
Map the actual component and finished product separately. Record who developed each, whose name appeared on it and who arranged manufacture. Where several businesses trade under similar names, distinguish the relevant legal entities. The component maker's factory address, the invoice issuer and the finished-product brand owner may represent different actors. Accurate identity work prevents technical findings from being assigned to the wrong organisation.
Apply the component liability conditions
Article 8(1)(b) concerns the manufacturer of a defective component where the component was integrated or interconnected within the product manufacturer's control and caused the product to be defective. These are substantive conditions, not a rule that every supplier named in a bill of materials is liable. Identify the alleged component defect and explain its effect on the complete product.
The provision is without prejudice to the finished-product manufacturer's liability. Article 8 also addresses that manufacturer's liability for damage caused by a defective component integrated or interconnected within its control. An integrator therefore cannot answer the injured person's claim simply by pointing to an outsourced part. Whether the conditions are established still depends on defectiveness, covered damage, causation, scope and any applicable exemption.
Control concerns authorisation and continuing capabilities
Manufacturer control has a defined meaning under Article 4. It covers specified actions by the manufacturer, authorisation or consent concerning third-party integration, interconnection, supply or modification, and the ability to supply software updates or upgrades. Evidence of approval can matter more than possession of the component at the time of the accident. A supplier's remote involvement does not itself answer the control question.
Preserve integration approvals, interface specifications, change permissions and update arrangements. Record whether a replacement part or software addition was authorised, merely compatible or introduced independently. The same manufacturer can control one component relationship while having no control over a later third-party change. A reliable chronology helps avoid assigning the finished product's entire service history to its original configuration.
Examine the component-specific exemption
Article 11(1)(f) allows the component manufacturer to establish an exemption where the finished product's defectiveness is attributable to that product's design or to instructions given by its manufacturer to the component manufacturer. For example, evidence may distinguish an unsuitable product-level design requirement from a part that departed from the agreed requirement. The statutory conditions must be proved; the exemption is not automatic.
Read the technical instructions and their revision history alongside the observed failure. Determine whether the supplier followed them and whether another characteristic of its component contributed. A broadly drafted design-responsibility clause does not substitute for this factual inquiry. The separate guide to defective components integrated into finished products examines the causal connection between component behaviour and overall product safety.
Shared liability and later recourse are different questions
Where two or more economic operators are liable for the same damage under the Directive, Article 12 provides for joint and several liability, without prejudice to national contribution or recourse rules. This does not turn every business in the chain into a liable operator. First determine which actors satisfy the relevant conditions and whether they are liable for the same damage.
Article 14 addresses remedies pursued after an economic operator has compensated the injured person, in accordance with national law. Article 12(2) contains a specific software recourse exception requiring both qualifying microenterprise or small-enterprise status and a contractual waiver by the integrating manufacturer. Small size alone is not general immunity from liability. Article 15 separately protects the injured person's position against contractual limitation or exclusion.
Keep the damage and applicable law visible
A defective component may damage only the finished product, cause injury or affect other property. Article 6 treats these categories differently, including the specified exclusion for a product damaged by a component integrated by its manufacturer or within its control. A technically established defect therefore does not establish every claimed loss as recoverable under this Directive.
The corrected scope applies to products placed on the market or put into service after 8 December 2026. Component supply, finished-product release and subsequent changes need separate dates. The final analysis should identify the product, each actor, alleged defect, integration control, causal link, damage category and possible exemption. That structure explains who may be responsible without reducing the inquiry to whichever company is closest to the failed part.
Records that help the review
Use the following as a practical starting point. Select and preserve records appropriate to the product, incident and applicable procedure.
- Component and finished-product manufacturer identities
- Integration approvals and design instructions
- Failure analysis and damage classification
