From DoP to DoPC: what the revised CPR changes in the declaration you already publish

Same job, wider scope

It helps to be clear about what is not changing. The declaration remains the legal instrument that anchors CE marking: the manufacturer's own statement, made under the manufacturer's own responsibility, about what the product does. Nobody else signs it, and no notified body converts it into a certificate. That part of the architecture survives the revision intact.

What changes is how much the statement has to say. The old Declaration of Performance did one thing - it declared performance in relation to essential characteristics. The Declaration of Performance and Conformity keeps that and adds a second declaration to it, about the product's conformity with the requirements that apply to it. One document, two kinds of statement, which is what the name is telling you.

That is a bigger change than it sounds, because the two statements are produced by different work. Performance comes from testing and from your technical documentation. Conformity comes from an assessment against requirements. A company that has a mature DoP process has solved the first and, in many cases, has never had to write the second down in this form.

The three things that get added

1. Conformity with product requirements

The DoPC declares performance against the applicable essential characteristics and, where relevant, confirms conformity with the functional, safety and environmental product requirements established under the CPR. In practice this is the part most likely to expose a gap between what a company knows about its product and what it has ever written down.

2. Environmental and climate content

This is the one with the longest lead time and it is worth separating the principle from the calendar. The principle: environmental performance becomes declarable content in the DoPC, calculated on EN 15804 life-cycle rules - the same methodology that sits behind an Environmental Product Declaration. The calendar: it phases in. Climate-change indicators come first, the declarable set widens on 9 January 2030 and again in 2032.

The practical consequence is that the DoPC is the first place a manufacturer without life-cycle data will feel its absence. EPD programmes run six to twelve months per product line, and they cannot be compressed past the capacity of your data and your verifier - so this is the item to start before the rest of the picture is clear, not after.

3. The Article 15(6) information

The DoPC also carries the information referred to in Article 15(6), notably the information required under Articles 31 or 33 of the REACH Regulation - substance information that many manufacturers already hold, but hold somewhere else, produced by a different function and on a different cycle. It travels with the declaration now.

Worth noting where this lands, because it is easy to get wrong: the REACH information arrives through Article 15(6), attached to the declaration itself. It is not a separate item of "documentation required under other Union law", even though such documentation is separately required elsewhere.

The form changes as much as the content

A DoP that exists as a PDF, produced per product and emailed on request, satisfies the old regime. The DoPC must be supplied by electronic means. Where it is made available via a website, it must be provided in an unamendable electronic format and be both human- and machine-readable. From 8 January 2026, the DoPC must also cover the first group of predetermined environmental essential characteristics listed in Annex II of the CPR. Publication carries two further conditions: it must be free of charge, and tied to the product by a unique identification code or a permalink that keeps resolving.

Read that list again as an IT requirement rather than a compliance one and its real weight appears. "A link that still resolves" is a statement about how you run a website, and most marketing sites fail it within one redesign. It is also the cheapest available rehearsal for the Digital Product Passport, where the same discipline applies with much longer time limits attached.

When this becomes your problem

Not on a date. The revised CPR does not switch product families over together: your family migrates when its new harmonised technical specification is adopted and made mandatory, with a coexistence period of at least a year before the new route is the only route. Until then your existing declarations stand.

Which family goes when is set out in the first CPR Working Plan, and we read it family by family in which construction products need a DPP first. Precast concrete, structural metallic products, and cement, building limes and hydraulic binders are at the front of the standardisation queue.

The trap in that sentence is the word until. Migration sets when the new declaration becomes mandatory; it does not set when the work starts. Life-cycle data, substance information and a durable link are all things you either have when your family arrives or spend a year acquiring after it does.

And then it becomes the centre of the passport

There is one more reason to treat the DoPC as more than a paperwork change. When the construction Digital Product Passport system arrives, the DoPC is the first thing Article 76 requires the passport to contain - the passport packages the declaration rather than replacing it. Everything you do to make the declaration structured, addressable and durable is work you do not repeat later.

We set out the full contents of the passport, and which function inside a manufacturer already holds each one, in what goes in a construction DPP. The short version for this article: a DoPC that is already a structured record rather than a laid-out document is most of the way to being passport-ready, and one that is a PDF is not.

What to do with the declaration you have now

1. Take one DoP and gap-check it against DoPC content. Performance, conformity, environmental characteristics, Article 15(6) information. One product, one afternoon; the output is a list of what you cannot currently state, which is the only honest starting point.
2. Find out who would write the conformity half. In most companies the performance statement has an obvious owner and the conformity statement has none. Naming that person is free today.
3. Start the EN 15804 data, whatever your family's position in the Working Plan. It is the one item on this list whose duration you cannot buy your way out of.
4. Get the substance information onto the same cycle as the declaration. REACH data that lives with a different team, updated on a different schedule, becomes a defect the moment it has to travel with the DoPC.
5. Fix the link before you need it. One durable, non-modifiable, machine-readable location per declaration, under a URL policy that survives a website redesign. This is the smallest change on the list and the one most likely to be quietly broken already.
