Short answer
The digital product passport regulation is a European regulation and in principle applies equally in all member states. This does not mean that implementation is identical everywhere. Language, the designated supervisory authority and sometimes an additional national register can differ from country to country. If you also sell mattresses outside the Netherlands, it is therefore advisable to ask your software supplier concretely how those differences are handled, and not to assume that one passport automatically complies everywhere.
The core of the passport itself — which data it should contain, how the QR code works, how long the data is kept — is fixed in the regulation and does not change by country. What can differ is the way member states organize supervision and which additional national obligations exist alongside the regulation. This directly affects the conversation you have with your software supplier, because they must be able to technically accommodate those differences.
What the regulation itself governs and what member states determine
The ESPR regulation describes at EU level what a digital product passport must contain and how it must be accessible. Member states themselves designate a supervisory authority and organize their own enforcement. For some product categories, national registration obligations have also existed for a longer time, for example regarding waste processing or packaging, which are separate from the product passport but continue to exist alongside it. Which specific national requirements will apply to mattresses is not yet fixed everywhere; the delegated act for mattresses has yet to be published. For the current status of this, we refer you to the official EUR-Lex text and to the competent supervisory authority in the country where you sell.
Language and accessibility of the passport
A question that often comes up in practice is whether the passport must be in the language of the country of sale. We address this topic in more detail elsewhere; what is relevant here is mainly that a software supplier who can only deliver Dutch-language passports gives you little room once you serve another country. So ask not only whether multilingual functionality is possible, but also how a change in the source text is implemented in all language versions at the same time. A passport that has been updated in one language and still shows old data in another is a risk you want to avoid.
National supervisory authorities and own registers
Supervision of compliance with the product passport lies with an authority that each member state designates itself. This can be a different organization than the authority you already know from, for example, product safety. For a company that sells in multiple countries, this means that there is not one central point where everything comes together, but that you can be dealing with different authorities. Some member states also already have their own product register for certain materials or waste streams, separate from the European passport. We are building an overview of how this differs from country to country in the knowledge base with country-specific information, so you don't have to find out for yourself which authority is competent in each country.
What this means for the conversation with your software supplier
If you also sell outside the Netherlands, it is wise to explicitly ask your software supplier how country-specific differences are tracked. Consider whether the system automatically alerts you when a country introduces an additional requirement, or whether you remain responsible for monitoring it yourself. Also ask how changes will be implemented once the delegated act for mattresses is published and which countries will be updated first. A supplier who cannot give you a concrete answer on this may leave you with a product passport that complies in the Netherlands but lags behind elsewhere. With a brief scan you can see in a few questions where your situation currently stands, even if you are active in multiple countries.
It is also useful to ask how the supplier handles proof of origin: which data come from you as manufacturer or importer, and which does the platform itself supplement based on public sources. Transparency on this, including a clear source in the official text, is part of a carefully constructed product passport. How we track that origin can be read on the page explaining where the information comes from.
Your own situation
Whether a particular national rule applies to your products and which authority in a specific country is responsible for oversight is something that varies from country to country and from situation to situation. For this, consult the official text on EUR-Lex or the supervisory authority in the country concerned, or put the question to a lawyer who is familiar with cross-border trade.
