One of the most common questions teams ask when preparing for Digital Product Passport readiness is simple: what data fields should actually go into a Digital Product Passport?
TL;DR: That question matters because many businesses already have product data, but they do not always have it organized in a way that supports future passport-linked workflows. Some information lives in ecommerce platforms, some in supplier sheets, some in ERP systems, and some in PDF documents or internal files.

The challenge is not only identifying fields. It is deciding how to structure them, who owns them, how they are validated, and how they can be maintained over time.
This guide explains the main categories of data fields that usually matter for Digital Product Passport readiness, how to think about them operationally, and what ecommerce teams should prepare now so they are not forced into last-minute data restructuring later.
Why field planning matters for DPP readiness
Digital Product Passport preparation is not just about collecting more information. It is about collecting the right information in a structured, governed, and reusable way.
If the data model is weak, teams often run into problems such as:
- important values stored in free-text fields
- supplier data arriving in inconsistent formats
- duplicate fields created in different systems
- missing documentation behind critical attributes
- no distinction between core product facts and channel content
- unclear ownership for sensitive or technical data
That is why field planning is one of the most important parts of DPP readiness. Before publishing anything, you need a clearer view of the product data structure underneath it.

A practical way to think about DPP data fields
Instead of trying to build one giant, flat list of passport fields, it is usually better to organize them into logical groups.
A practical DPP-oriented structure often includes:
- product identity fields
- classification and category fields
- technical and specification fields
- material and composition fields
- supplier and source-related fields
- document and evidence fields
- lifecycle, service, or support-related fields
- localization and market-specific fields
- governance and status fields
- publishing and passport-linking fields
This structure helps teams avoid mixing operationally different types of information together.
1. Product identity fields
These are the basic fields that establish what the product is and how it is identified in your systems.
Typical product identity fields include:
- internal product ID
- SKU
- parent product ID where relevant
- variant ID where relevant
- product name
- brand
- model number
- GTIN, EAN, UPC, or equivalent identifiers where applicable
- product family or range
- version or revision reference where needed
These fields are foundational because they connect the passport-linked record to the correct product entity. If identity data is inconsistent, everything else becomes harder to govern.
2. Classification and category fields
Products need to be classified correctly so required attribute groups, workflows, and data rules can be applied consistently.
Typical classification fields include:
- primary category
- subcategory
- product type
- product family classification
- channel taxonomy mapping
- internal classification codes
- market-specific category mapping where needed
This matters because many required fields are usually tied to the product type. If categories are inconsistent, field requirements become inconsistent too.
That is one reason why structured taxonomy work is often a hidden dependency for DPP readiness.
3. Technical and specification fields
Technical fields describe the product in a structured and measurable way. These are often among the most important groups for passport-linked readiness.
Examples may include:
- dimensions
- weight
- capacity
- performance-related values
- power or energy-related fields where relevant
- compatibility information
- usage constraints
- operating conditions
- durability or maintenance-related attributes where relevant
- variant-specific specifications
The key is to store these as structured attributes where possible, not only in descriptive text blocks. If technical facts live only inside paragraphs or PDFs, they become harder to validate and reuse.
4. Material and composition fields
For many teams, this is one of the field groups that requires the most cleanup because composition details are often scattered, inconsistent, or incomplete.
Depending on product type, relevant fields may include:
- main materials
- component materials
- composition percentages where relevant
- surface or finish-related details
- packaging material information
- material declarations from suppliers
- supporting material documents or references
Even when all final requirements are not yet known for a category, material data is often one of the strongest indicators of whether a business is building a DPP-ready product record or just maintaining marketing content.
5. Supplier and source-related fields
Many important DPP-related data points originate with suppliers, manufacturers, or upstream partners. That means supplier-linked fields should be treated as a structured part of the data model, not as a side note.
Typical supplier-related fields may include:
- supplier name
- supplier ID or reference code
- manufacturer reference
- source document reference
- supplier-provided field status
- date received
- review status
- evidence link or file reference
It is also useful to track whether a value is supplier-declared, internally verified, or still awaiting review. That makes the field model more operationally useful later.

6. Document and evidence fields
Some product data points should not exist without supporting evidence, especially when they depend on supplier information, technical documentation, or controlled internal review.
Useful document-related fields may include:
- document type
- document ID or reference
- linked file location
- document status
- issue date
- expiry date where relevant
- review date
- review owner
- linked product or variant relationship
This helps prevent a common issue where teams have files somewhere in a shared drive but cannot reliably connect them to the right product record during review or publishing.
7. Lifecycle, maintenance, and support-related fields
Some product categories may require more operational detail about how products are maintained, serviced, or supported over time.
Depending on your product type, relevant fields might include:
- care or maintenance instructions
- repair or service references
- replaceable component information
- support documentation references
- end-of-life handling references
- warranty-related support details where relevant
These fields are often overlooked early because teams focus first on catalog merchandising. But operational readiness usually requires broader lifecycle thinking than ecommerce copy alone.
8. Localization and market-specific fields
If you operate across multiple languages or markets, some DPP-linked information may need localized handling.
Useful field groups may include:
- localized product names
- localized descriptions
- translated attribute values where needed
- market-specific compliance notes
- localized document references
- language status or translation status
- review state by locale
The key is to avoid mixing master product truth with local merchandising text in an uncontrolled way. Multilingual readiness should be part of the field model, not an afterthought.
This becomes especially important for teams operating across multiple storefronts or markets. A dedicated guide on this is worth linking once published: DPP and Multilingual Product Data: What Teams Miss.
9. Governance and workflow fields
One of the most useful things teams can do is add fields that support governance directly inside the product record structure.
Examples include:
- data owner
- review owner
- approval status
- completeness status
- source confidence or verification status
- last reviewed date
- change reason where needed
- workflow stage
- publishable status
These fields do not describe the product itself, but they are essential for making DPP preparation operationally manageable. Without them, teams rely on separate spreadsheets or email threads to track readiness.
10. Publishing and passport-linking fields
Eventually, teams need to think about how a product record connects to the published passport experience.
That may include fields such as:
- public record identifier
- passport page URL or record URL
- QR-linked reference
- publication status
- effective date
- last published date
- version or revision status
- locale-specific publication state where relevant
Even if you are not publishing passport-linked records yet, planning these fields early can prevent major rework later.
You can connect this operationally to your broader DPP planning using the Digital Product Passport Guide.
A simple DPP field framework ecommerce teams can use
If you want a simpler framework, organize your DPP-related fields into five core layers:
- Identity — what the product is
- Specifications — what the product is made of and how it performs
- Source and evidence — where the information came from
- Governance — who owns, reviews, and approves it
- Publishing — how it becomes a controlled public-facing record
This framework is often enough to start designing a DPP-ready data model without overcomplicating the first phase.
Common mistakes when planning DPP fields
Teams often make the same mistakes early in DPP preparation.
- storing important fields inside descriptions instead of structured attributes
- mixing product truth with channel merchandising content
- failing to record where values came from
- ignoring multilingual field requirements until later
- keeping evidence files disconnected from the product record
- tracking approvals outside the main product workflow
- waiting for perfect certainty before cleaning up the data model
The earlier these issues are addressed, the easier DPP readiness becomes.

Final thoughts
The question is not only which data fields should go into a Digital Product Passport. The better question is whether your business can manage those fields in a structured, governed, and maintainable way.
That is what separates a future-proof DPP-readiness program from a rushed data collection exercise.
If you start with field structure, source tracking, governance, and publishing logic early, you put your team in a much stronger position for what comes next.
FAQ
What are the main data fields in a Digital Product Passport?
The main field groups usually include product identity, classification, technical specifications, material details, supplier-linked fields, document references, localization fields, governance fields, and publishing-related fields.
Do all products need the same Digital Product Passport fields?
No. Field requirements vary by product type, category, and market context. That is why teams should define structured field groups by product family rather than forcing every product into one generic template.
Should DPP fields be stored as structured attributes?
Yes, wherever possible. Structured attributes are easier to validate, govern, localize, and publish than values hidden inside paragraphs, spreadsheets, or PDF files.
Why are supplier and evidence fields important?
Many DPP-related data points depend on supplier-provided information or supporting documents. Tracking source and evidence makes the product record more reliable and easier to review later.
Do governance fields matter in a Digital Product Passport data model?
Yes. Fields like owner, review status, approval state, completeness status, and last reviewed date help teams manage readiness operationally instead of relying on disconnected workflows.
Where should teams start when planning DPP fields?
Start by grouping fields into logical sections such as identity, specifications, supplier data, evidence, governance, and publishing. That usually creates a strong enough foundation for the next stage of DPP preparation.
