Section 1

What is the difference between an integrated component, a remote data processing solution, and an external dependency?

Under the CRA, an integrated component is a software or hardware component that forms part of the product with digital elements. A remote data processing solution can also form part of the product where it meets the Article 3(2) definition. Other outside systems or services may remain external dependencies rather than part of the product itself.

The consequence is different in each case:

- integrated components are part of the product and trigger due diligence under Article 13(5)

- remote data processing solutions that meet the CRA definition are also part of the product

- outside systems may remain external dependencies, but their risks still have to be considered in the cybersecurity risk assessment and mitigated through product-level measures

Section 2

Does the manufacturer remain responsible for the cybersecurity of the whole product when it integrates third-party components?

Yes.

The CRA places the compliance obligation on the manufacturer of the finished product. The Commission FAQ is explicit that vulnerability-handling obligations apply to the product in its entirety, including integrated components.

Citations
Section 3

Are CRA cybersecurity risk assessment and component due diligence the same obligation?

No.

The draft guidance treats them as distinct but complementary obligations. The cybersecurity risk assessment covers risks affecting the product, including risks originating outside the product. Due diligence under Article 13(5) is the additional obligation to verify, in a risk-based way, that third-party integrated components do not undermine the product's compliance.

Section 4

What does due diligence mean when integrating third-party components?

It means taking appropriate, risk-based steps so that the integrated components do not compromise the cybersecurity of the product.

Recital 34 and the Commission FAQ give examples such as checking whether the component already bears the CE marking, checking whether it receives regular security updates, checking relevant vulnerability databases, and carrying out additional security tests where appropriate.

Citations
Section 5

Does a CE-marked component automatically make the finished product compliant?

No.

The Blue Guide explains that CE-marked components do not automatically guarantee that the finished product also complies. In the CRA context, a CE-marked component can support the integrating manufacturer's assessment, but the integrating manufacturer still has to ensure that the finished product complies as a whole.

Citations
Section 6

Can a manufacturer integrate components that are not CE-marked under the CRA?

Yes.

The CRA does not require manufacturers to integrate only CE-marked components. Manufacturers can integrate components that are outside the CRA, that were placed on the market before the CRA applies, or that were never placed on the market as CRA products. But they still have to exercise due diligence and ensure that the finished product complies.

Citations
Section 7

Can the integrating manufacturer rely on the component manufacturer's own CRA work?

Partly, but not completely.

The Commission FAQ says that where the component is itself subject to the CRA, the integrating manufacturer can rely in part on the component manufacturer's lifecycle work, such as its vulnerability handling and conformity documentation. But that does not transfer the finished-product manufacturer's own obligations.

Citations
Section 8

Do vulnerability-handling obligations extend to integrated components?

Yes.

Recital 34 and the Commission FAQ say that the CRA vulnerability-handling obligations apply to the product in its entirety, including all integrated components.

Citations
Section 9

If the manufacturer finds a vulnerability in an integrated component, what must it do?

The CRA expects more than just recording the issue.

Article 13(6) and recital 34 require the manufacturer to inform the person or entity manufacturing or maintaining the component, address and remediate the vulnerability, and, where applicable, provide that person or entity with the applied security fix.

Citations
Section 10

What if an integrated component stops receiving support before the finished CRA product's support period ends?

That does not end the finished-product manufacturer's duties.

The Commission FAQ says the manufacturer must comply with the vulnerability-handling obligations for the duration of the product's own support period, for the product in its entirety, including integrated components. If the upstream component is no longer supported, the manufacturer may still need to patch it, replace it, disable affected functions, or mitigate the risk through other means.

Citations
Section 11

Must the risk assessment also consider risks from outside systems that are not themselves part of the product?

Yes.

The draft guidance says the cybersecurity risk assessment must cover relevant risks that originate outside the product itself, such as external networks, environmental factors, infrastructure, or other systems on which the product relies. The CRA then requires those risks to be mitigated through product-level measures rather than by imposing obligations on the outside environment.

Section 12

How should a manufacturer treat third-party SaaS or cloud services that the product relies on?

It depends on whether the service qualifies as a remote data processing solution.

If the relevant software is designed and developed by the manufacturer or under its responsibility, and its absence would prevent the product from performing one of its functions, it can be part of the product as RDPS. If that second condition is met but the software is a third-party solution not designed and developed by the manufacturer or under its responsibility, the draft guidance says it should be treated similarly to a third-party component: the manufacturer must assess the integration risk and exercise due diligence.

Citations
Section 13

If a product relies on a cellular network or general internet connectivity, does the manufacturer have to exercise component-style due diligence toward the network provider?

Not necessarily.

The draft guidance's cellular-network example says such a network does not qualify as RDPS and should not be treated like a third-party component where no provider software is integrated into the product. The manufacturer still has to assess the network-related risks and address them through product-level controls.

Citations
Section 14

Can the manufacturer shift CRA responsibility to a component supplier or cloud provider by contract?

No.

The draft guidance says the CRA does not provide for transfer of cybersecurity risk or responsibility to users or third parties. Contracts, service levels, and supplier commitments can support compliance and due diligence, but the obligation to place a compliant product on the market remains with the manufacturer.

Citations
Section 15

Must the technical documentation describe integrated components, remote data processing, or reliance on third-party cloud solutions?

Yes, where relevant.

Annex VII requires technical documentation to contain enough information to assess compliance, including the vulnerability-handling processes and the cybersecurity risk assessment. The draft guidance adds that manufacturers should indicate in the technical documentation whether the product has RDPS or relies on third-party cloud solutions and should describe those solutions.

Section 16

If no upstream fix is available for a vulnerable integrated component, can the manufacturer still be expected to act?

Yes.

The Commission FAQ says that if a vulnerability in an integrated component cannot be adequately addressed by the original component supplier, the integrating manufacturer still has to remediate it by other means, for example by switching out the component, developing a patch itself, or disabling the affected functionality where that is the appropriate product-level remedy.

Citations
Section 17

If the CRA product is meant to be integrated into a larger system, do deployment assumptions and outside interfaces still matter?

Yes.

The Commission FAQ says intended purpose, reasonably foreseeable use, and conditions of use can include direct or indirect logical or physical connections to devices or networks. That means the manufacturer has to take the integration context into account in the risk assessment and provide users with the information needed for secure deployment and operation.

Citations
Section 18

If a manufacturer contributes code or funding to a FOSS dependency that it integrates, does that make it responsible for that dependency's own CRA compliance?

No, not by itself.

The draft guidance says manufacturers integrating FOSS components do not become responsible for those components' individual CRA compliance merely because they contribute source code to their maintenance. The same logic applies where manufacturers provide financial support to keep a dependency viable. The integrating manufacturer still remains responsible for its own product and still has to exercise due diligence toward the integrated dependency.

Citations
Section 19

Does integrating a FOSS dependency into a commercial product make that dependency itself a CRA product?

No.

The draft guidance says the fact that other manufacturers integrate a FOSS component into monetised products does not by itself change the status of that component under the CRA. Whether the CRA applies to the dependency itself depends on whether the entity publishing it places it on the market. A FOSS component published for integration by other manufacturers can therefore remain outside the manufacturer regime, or fall under the steward regime, if the publisher does not monetise that component.

Citations
Section 20

Can the publisher of an integrated FOSS dependency be a steward rather than a manufacturer?

Yes.

Where a legal person publishes a FOSS dependency intended for commercial activities but does not place that specific dependency on the market, it may be an open-source software steward rather than a manufacturer. The draft guidance also says the same legal entity can be a manufacturer for one FOSS and a steward for another, including being a manufacturer for a paid version and a steward for a free or community version. That changes the publisher's own CRA role, but it does not remove the integrating manufacturer's obligations for the finished product.

Citations
Section 21

Does a package repository or hosting platform automatically become responsible for every dependency it hosts?

No.

The draft guidance's package-repository example says that merely hosting a FOSS library in a public repository does not by itself give the repository CRA obligations for that dependency. More generally, hosting or infrastructure support does not automatically make a legal person responsible for every project it hosts. A legal person may become a steward only for specific FOSS where it systematically provides sustained support and ensures that project's viability.
