Market surveillance and passport enforcement
Maintained by Y. Lietzke, editor · 2 issues in this hub
In short
A market surveillance check on a Digital Product Passport begins with a scan: does the carrier resolve, publicly and immediately, to the data the applicable act requires. Findings then come from inconsistency — passport data that contradicts the declaration of conformity or the technical file — and from passports that were accurate at launch and never updated. The cheapest preparation is to rehearse the check yourself, from outside your own network.
What is market surveillance and passport enforcement, and why does it matter?
Enforcement of product information is not new; what is new is that the information is now published, machine-readable, and checkable by anyone with a phone. That lowers the cost of an inspection dramatically, and it means your data quality is visible to customers and competitors as well as to authorities.
This hub covers the enforcement side: what authorities look at, which documents must agree with each other, how change control keeps a passport true over time, and what importers must be able to show about the shipments they release.
What do you need to get right?
- First check
- Does the carrier resolve — publicly, without an app, in the language of the market.
- Second check
- Do the passport, the declaration of conformity, the technical file, the label, and the product agree.
- Most common failure
- Accurate at launch, never republished after an engineering change.
- Preparation
- A cold scan test on a finished unit, from an external network, timed and recorded.

Frequently asked questions
- How will authorities check a Digital Product Passport?
- By scanning the data carrier on the product, packaging, or documentation and comparing the published data against the declaration of conformity, the technical file, and the physical product.
- What happens if a passport link stops working?
- A carrier that does not resolve is among the fastest findings an authority can record, independent of your underlying compliance. Own the resolver domain and keep the link stable for the product's life.
- Do passports have to be updated after launch?
- Yes — the passport is a maintained record. Connect engineering change control to republication and give one named owner sign-off.
