Upload evidence documents
Evidence is added directly within the data request response form — there is no separate "Upload Evidence" navigation item. Open a data request, scroll to the Documents section, and add your evidence there as part of your response.
Direct file upload from your device is planned. Not available today. For now, add evidence by providing a URL that links to the document (see below).
When to Upload Evidence
Evidence documents are files that substantiate the data values you provide in a response. Uploading strong, well-labelled evidence alongside your data values serves two purposes: it gives the customer confidence in the accuracy of your submission, and it provides the documentation trail that the customer needs to satisfy their own DPP verification requirements under EU Battery Regulation 2023/1542.
Upload evidence in the following circumstances:
When the customer explicitly requests it. The request form may list specific documents under a Documents section — for example, "Please provide the UN 38.3 transport test report for this cell" or "Attach the LCA study underpinning your carbon footprint value."
Proactively, when your values need substantiation. For quantitative claims — carbon footprint, cycle life, energy density, recycled content percentages, hazardous substance concentrations — a data value without a supporting document is difficult for a customer to defend in a DPP audit. If you are providing values derived from a laboratory test, a lifecycle assessment, or an analytical report, upload the underlying document even if it has not been explicitly requested.
How to Add Evidence Within a Data Request Response
- Open the data request response form (see Respond to a Data Request)
- Scroll to the Documents section at the bottom of the response form
- Click Add Document
- Enter the URL where the document is hosted (for example a link to the document in your own document store or a shared location the customer can reach)
- In the Document description field, write a clear, specific description of what the document is and what it proves (see guidance below)
- Click Save
- Repeat for each document you want to add
You can add multiple documents to a single response. There is no limit on the number of documents per response.
Make sure the URL you provide remains accessible to the customer for as long as they need to review and rely on your evidence. A link that later stops working leaves your data value without its supporting document.
Direct file upload — selecting a file from your device, with support for formats such as PDF, JPG, PNG, DOCX, and XLSX up to a per-file size limit — is planned. Not available today.
Writing Effective Document Descriptions
The description field is read by the customer and potentially by third-party verifiers reviewing the DPP. A good description is specific and connects the document to the specific claim it supports.
Effective descriptions:
- "LCA study (TÜV Rheinland, March 2025) supporting the cradle-to-gate carbon footprint value of 42.8 kg CO₂e/kWh in field CF-001"
- "REACH compliance declaration (SGS certificate RCH-2025-00443) confirming cobalt sulphate contains no SVHC above 0.1% w/w"
- "Certificate of Analysis (lab batch 24-LOT-0091) confirming lithium carbonate purity ≥99.5% as declared in the composition field"
Descriptions to avoid:
- "Test report"
- "Compliance document"
- "See attached"
Uploading Documents After Submission
If you realise after submitting a response that you forgot to include a supporting document, or if you receive a newly completed laboratory report after submission, you can upload additional documents to a submitted response until the customer accepts it.
- Navigate to Data Requests → find the submitted request
- Click the request to open the detail view
- Scroll to the Documents section
- Click Add Document and upload as described above
Once the customer accepts the response, no further document uploads are possible. At that point, if a critical document needs to be added, contact the customer to discuss reopening the response.
What Customers Can Do With Your Evidence
When the customer reviews your submission, they have full access to every document you have uploaded:
- View — customers can open and read documents directly in the Traceable viewer
- Download — customers can download documents to their own systems
- Attach to the DPP — customers can select your documents to be formally attached to the DPP record, making them part of the publicly accessible or authority-accessible documentation package
- Reference in field notes — customers can cite your document (by name and reference number) in DPP field notes, establishing the evidential link between a specific DPP data value and its source document
- Share with verifiers — when a DPP is sent for third-party verification, the attached documents are shared with the assigned verifier
Your documents remain your property. You grant Traceable and the receiving customer a licence to use them for the specific purpose of DPP compliance. Your documents are not shared with other customers or third parties beyond the DPP verification workflow you are part of.
