26 of 26 sections
Section 1

Can hardware and software together constitute a single product with digital elements?

Yes.

The CRA definition is broad enough to cover hardware and software supplied together as one product, including cases where the hardware and software are supplied separately but are intended to operate together as a single product.

Section 2

What is the key CRA boundary test for deciding whether software forms part of a hardware product?

The draft guidance says the key question is whether the software is necessary for the product to perform its intended functions in light of the product's intended purpose and reasonably foreseeable use.

The delivery channel is not decisive on its own. What matters is whether the hardware is designed to operate together with that software as part of one product concept.

Section 3

Does the delivery channel decide whether software is part of the same CRA product boundary?

No.

Software can still be part of the same product even if it is obtained through a separate channel such as an app store, a manufacturer website or another digital link after the hardware is supplied.

Section 4

Can software that is not preloaded on the hardware still be part of the same product?

Yes.

The Commission FAQ expressly lists software placed on the market together with hardware even where it is not preloaded, such as printer drivers, laptop operating systems and tools used to design and program FPGAs.

Section 5

Are printer drivers part of the same CRA product as the printer?

They can be.

The Commission FAQ gives printer drivers as an example of software that may be placed on the market together with hardware. The draft guidance then makes the point more explicit: where the printer cannot fulfil its intended purpose without the drivers, the printer and the drivers together constitute a single product with digital elements.

Section 6

Can a companion mobile app be part of the same CRA product as a hardware device?

Yes, if it is necessary for the product's intended functionality.

The draft guidance gives the example of a fitness wearable and a companion smartphone app that together form one product because they are designed and intended to operate together to deliver the product's functionality.

Section 7

If an app is genuinely optional and the device can still perform its intended functions without it, is it automatically part of the same product?

Not automatically.

The draft guidance points to necessity as the decisive factor. If the device can still perform its intended functions without the app, that points away from treating the app as part of the same combined product, although the exact answer still depends on intended purpose and reasonably foreseeable use.

Section 8

When is software more likely to be treated as standalone software rather than part of a CRA hardware product boundary?

It is more likely to be treated as standalone software when it is supplied as software in its own right and is not necessary for a hardware product to perform its intended functions.

The Commission FAQ confirms that standalone downloadable software can itself be a product with digital elements. The draft guidance then distinguishes that case from software that forms part of a hardware-software product.

Section 9

Does the standalone-software placement logic also apply when software forms part of a hardware-software product?

No.

The draft guidance says its specific explanation for digitally supplied standalone software applies only to standalone software. It does not govern cases where the software is combined with hardware as part of one product.

Section 10

If software is supplied on a USB device or other physical medium, is the CRA analysis the same as for digitally delivered standalone software?

No.

The draft guidance distinguishes software supplied via physical means from standalone software supplied digitally. In that case, the physical carrier with the software on it is treated as the product supplied for distribution.

Section 12

Does source code fall outside the CRA just because it still has to be compiled or interpreted?

No.

The draft guidance says whether code is uncompiled, compiled or interpreted is not relevant to whether it is software within the CRA.

Section 13

If a manufacturer supplies source code to customers as part of a commercial activity, is that code considered placed on the market?

Yes.

The draft guidance says that where a manufacturer provides customers with computer code as part of its commercial activity, that code is considered to be placed on the market regardless of whether it is machine code or source code.

Section 14

If source code is licensed to a customer for later adaptation, who is responsible for what under the CRA?

The draft guidance says the original supplier is responsible for the code it placed on the market. The customer's later adaptations and compilation are a separate matter.

Section 15

Are sample code snippets, tutorial code or demo code automatically treated as products placed on the market?

No.

The draft guidance says sample or demo code provided as part of tutorials or training materials is not considered placed on the market.

Section 16

Is unfinished code shared during design and development automatically treated as a product placed on the market?

No.

The draft guidance says unfinished code shared during design and development is not considered placed on the market because its manufacturing phase is not complete. Separately, Article 4(3) deals with unfinished software intentionally made available for testing under specific conditions.

Section 17

Are separately marketed software or hardware components still products in their own right under the CRA?

Yes.

Article 3(1) expressly includes software or hardware components placed on the market separately. The Commission FAQ gives firmware, embedded software, integrated circuits, motherboards and sensors as examples.

Section 18

Are websites or SaaS offerings automatically products with digital elements?

No.

The Commission FAQ says websites that do not support the functionality of a product are not themselves products with digital elements. It also says standalone SaaS or other cloud solutions designed and developed outside the responsibility of a manufacturer are not themselves products with digital elements. Where such elements meet the definition of remote data processing, they may instead fall within scope on that basis.

Section 20

Do long development cycles, legacy architectures or interoperability constraints take a complex system outside the CRA?

No.

The draft guidance says those characteristics do not in themselves exclude a complex system from the CRA. They affect how the CRA's risk-based compliance analysis is applied, not whether the product is in scope.

Section 21

Can remote data processing solutions be part of the same CRA product boundary?

Yes.

The CRA definition of a product with digital elements includes its remote data processing solutions. Whether a specific remote function qualifies depends on the separate Article 3(2) test, but the product boundary is not limited to the local hardware or software alone.

Section 22

Can external engineering or programming tools still form part of the same CRA product boundary?

Yes.

The Commission FAQ gives tools used to design and program FPGAs as an example of software placed on the market together with hardware. Read together with the draft guidance, this shows that relevant software does not need to be preloaded on the hardware or run on the hardware itself. If, in light of the intended purpose and reasonably foreseeable use, the software is necessary for the hardware product to perform its intended functions or to be meaningfully used, it can form part of the same product boundary.

Section 23

If a required app runs on a user's separate smartphone or computer, does that host device automatically become part of the same CRA product?

Not automatically.

The cited sources identify the wearable and the manufacturer-provided smartphone application as together constituting a single product because they are designed and intended to operate together. At the same time, the Commission FAQ separately recognises mobile apps and smartphones or laptops as products with digital elements in their own right. Taken together, those examples indicate that the necessary app can fall within the combined product boundary without automatically absorbing the user's general-purpose host device into that same boundary.

Section 24

Can remote software developed by an external provider still be part of the CRA product boundary?

Yes, if it is designed and developed under the manufacturer's responsibility.

The draft guidance explains that remote data processing can qualify as part of the product not only when it is developed fully in-house, but also when an external provider develops it solely on behalf of the manufacturer, based on the manufacturer's designs and specifications. In that situation, the remote software can still fall within the product boundary as remote data processing.

Section 25

Does the CRA product boundary extend to the remote servers or cloud hardware on which a remote function runs?

No, not as such.

The draft guidance explains that remote data processing is defined as the software elements of data processing at a distance. It is not meant to include, as part of the product boundary, the hardware that the remote data processing relies on. So the relevant remote software may fall within the product boundary, but the entire hosting infrastructure does not automatically do so as hardware.

Citations
Section 26

If a product depends on a third-party SaaS, PaaS or IaaS element that the manufacturer did not design, does that element automatically become part of the product as remote data processing?

No.

For remote functionality to qualify as remote data processing, the software must be designed and developed by the manufacturer or under its responsibility. The draft guidance says standard third-party SaaS, and comparable third-party elements in PaaS or IaaS stacks, do not meet that test merely because the product depends on them. Instead, they should be treated similarly to third-party components: the manufacturer must assess the resulting risks and address them through product-level measures and due diligence.
