If the digital product passport is missing while your product falls under its scope, the first and most direct consequence is that the product cannot lawfully be placed on the market. The regulation ties the passport to placing on the market: no passport means that a condition for market access has not been met. Furthermore, supervisory authorities can take action, a customer or buyer further down the chain can get stuck because they too need a passport, and a trading partner can decide simply not to accept a product anymore.
This is followed by consequences that are less visible but carry more weight in practice: delays in deliveries, additional questions from retailers or contracting authorities, and time pressure at the moment when you can least use it. Which sanctions a supervisory authority can concretely impose and how strictly it will be enforced cannot be described in general terms; that is up to the competent supervisory authority and, for your own situation, up to a lawyer.
Market access is the core of the regulation
The regulation for digital product passports is primarily a market condition. For the product groups for which a passport becomes mandatory, the passport is part of what a product may be placed on the market with. This does not only affect the manufacturer. An importer who places a product on the European market can also be designated as a responsible party. Anyone who is unsure which role applies in their case will find in the knowledge base with guidance per situation an overview of how those roles are structured.
The consequence of a missing passport is therefore not primarily a fine, but a blockade: the product does not enter the chain, or gets stuck somewhere because a next party needs the passport to be able to proceed themselves. For companies supplying in multiple product groups simultaneously, that is a real operational risk, apart from what a supervisory authority does with it.
What supervisory authorities can do
The regulation provides scope for supervision and enforcement, worked out at national level. Supervisory authorities look at whether the passport is present, whether the data in it are correct, and whether the party responsible for the product has actually fulfilled that obligation. How a supervisory authority acts in practice, which steps are taken in that regard and what specific consequences that has, cannot be predicted in general terms and moreover differs per Member State. For the precise powers and procedures, the official text of the regulation and the competent supervisory authority are the appropriate source, not a general description on this page.
What can be described is the structure: the regulation distinguishes obligations for those placing the product on the market, and leaves the working out of sanctions to the Member States themselves. This means that the way something is controlled and what consequences attach to it can differ from country to country. Companies supplying in multiple EU countries are well advised to look at this separately rather than assume one regulation that produces the same result everywhere.
Consequences beyond supervision
Aside from what a supervisory authority can do, there are consequences that are closer to daily practice. A wholesaler or retailer that is itself required to display a passport will quickly ask questions of a supplier without a passport or pause the delivery. In procurement procedures, the absence of a passport can be grounds for setting aside a tender. And in a chain where multiple parties depend on each other's data, a missing passport has an effect on everyone who comes after.
Moreover, having to set up a passport again under time pressure usually costs more time and effort than when done calmly and in advance. Unclear documentation requirements, uncertainty about where data should come from and who within your company is responsible, are often the reason a passport is not finalized at the last moment. Frequently asked questions about this, from who must submit the passport to what happens when a product changes, are collected on the page with answers to questions entrepreneurs often ask.
Know your position in advance
Most of these consequences can be prevented by finding out in time whether, and for which products, a passport is mandatory and what is needed for it. This does not start with a legal investigation, but with a few targeted questions about your product and your role in the supply chain. With the product scan that provides an initial indication in a few questions you gain insight into where your situation stands approximately, without first having to review the full regulation.
Whether the passport is mandatory in your case, from when, and what that concretely means for your products, ultimately differs per situation and is best verified with a lawyer or checked with the competent supervisory authority. Prodpas.eu does help you get started: the free quick-scan provides an initial direction, and the knowledge base explains the concepts and obligations without legal jargon.
