Digital Product Passport (DPP)

Digital Product Passport (DPP)

Key Takeaways

• A DPP is a structured digital record of a product’s composition, origin, repairability and end-of-life handling.
• It is reached through a data carrier on the product — typically a QR code or Data Matrix, which has to be marked somewhere.
• Batteries come first, with other categories following under the EU Ecodesign for Sustainable Products Regulation.
• The carrier must last as long as the product, which pushes it toward permanent marking rather than labels.

Digital Product Passport

A Digital Product Passport is a structured, machine-readable set of data about a specific product — its materials, composition, origin, environmental footprint, repairability and end-of-life instructions — accessible to regulators, recyclers, repairers and consumers through a data carrier affixed to the product itself. It is a central instrument of the EU Ecodesign for Sustainable Products Regulation and the wider circular economy program.

The regulatory intent is to make information that currently sits inside a manufacturer’s systems travel with the product. A recycler receiving a component at end of life should be able to determine what it is made from; a repairer should be able to identify parts; a regulator should be able to verify claims.

What This Means Physically

The policy discussion is about data, but the obligation lands on the product as a marking requirement. For a plastic component that means four practical constraints:

Rollout and Scope

• Batteries are the first category under the EU Batteries Regulation, with the battery passport obligation arriving ahead of the wider scheme — which is why battery and automotive supply chains are furthest along.
• Further categories follow under ESPR through delegated acts, with textiles, electronics, construction products and packaging among those identified as priorities.
• The obligation reaches down the supply chain. A moulder supplying a component into an affected product will be asked for material composition and traceability data even where the moulder is not the party holding the passport obligation.
• Timelines and detailed requirements are still developing through delegated acts, so specific dates and data fields should be confirmed against current guidance rather than treated as settled.

Why Marking Method Matters Here

A DPP carrier has an unusual durability requirement: it must be readable at the point the product is discarded, often years later and after weathering, wear and cleaning. That is a materially harder requirement than a code needed only through distribution:

• Labels are the weakest option. Adhesive failure, abrasion and weathering all remove them, and a missing carrier means a missing passport.
• Printed inks are intermediate. They can be durable, but they are an applied layer and their survival depends on substrate pretreatment holding up over years.
• Laser marking is the most durable route, because the contrast is a change in the polymer itself — the mechanism that also makes it the standard for UDI and anti-counterfeiting work.
• Moulded-in codes cannot carry variable data, which rules them out wherever item-level or batch-level uniqueness is required.

Marking a code is also only part of the obligation. The data behind it has to be maintained, hosted and kept accessible, which is a systems commitment rather than a production one.

Preparing for It as a Component Supplier

Most plastics processors will meet the DPP as a customer requirement rather than as a direct legal obligation, and the requests tend to arrive before the regulation itself does. Work that pays off regardless of exactly how the delegated acts land:

• Know your material composition properly. Full disclosure of resin, masterbatch, filler and additive content, including regrind provenance, is the data most frequently requested and the hardest to assemble retrospectively.
• Establish lot-level traceability linking finished parts to resin lots and process records. Item-level serialisation is a larger step, but lot-level traceability is often sufficient and is the foundation for anything finer.
• Find the mark location early. A data carrier needs a flat, accessible surface that survives assembly and remains readable at end of life — a constraint far easier to satisfy at the design stage than by retrofit.
• Qualify the carrier aged, not new. Readability at end of life is the actual requirement, so grading should follow weathering, wear and cleaning exposure.
• Check additive declarability. Substances of concern have to be declared, which can make an otherwise convenient additive an awkward choice.
• Treat recyclate content as reportable data. Where recycled content is claimed, expect to evidence it rather than assert it.

Frequently Asked Questions

What is a Digital Product Passport?

A structured, machine-readable record of a product’s materials, composition, origin, environmental footprint, repairability and end-of-life handling, reached through a data carrier attached to the product. It is a central instrument of the EU Ecodesign for Sustainable Products Regulation, intended to make information that currently sits in manufacturers’ systems travel with the product itself.

Which products need one first?

Batteries, under the EU Batteries Regulation, which is why battery and automotive supply chains are the furthest advanced. Further categories follow through delegated acts under ESPR, with textiles, electronics, construction products and packaging among the identified priorities. Because the detail is still arriving through delegated acts, specific dates and data fields should be confirmed against current guidance rather than assumed.

What does a DPP mean for a plastics moulder?

Two things. A data carrier — usually a QR code or Data Matrix — has to be applied to the part and survive its service life, which is a marking and qualification problem. And material composition and traceability data will be requested by customers further up the chain even where the moulder does not hold the passport obligation directly.

Why does the carrier need to be permanent rather than a label?

Because it must be readable at end of life, when the product is being sorted for repair or recycling — potentially years after manufacture and after weathering, wear and cleaning. A label that has fallen off means a passport that cannot be reached. That durability requirement is what pushes DPP carriers toward laser marking, where the contrast is a change in the polymer rather than an applied layer.

Can a DPP code be moulded into the tool?

Only for the fixed portion. Where the passport requires item-level or batch-level uniqueness, the code carries variable data and therefore has to be applied in production rather than formed by the tool. A moulded-in element can carry constant information, but a serialised carrier needs a marking process that changes what it writes from part to part.
