OEM & Private Label
Certification After Rebranding: What Changes When Your Logo Goes On
What happens to CE, UKCA, ETL and test reports when you put your own brand on an OEM EV charger: manufacturer role, labels, files and when to retest.

Key takeaways
- 1A certificate is issued for a product, a manufacturer and a model name. When you rebrand, the product may be the same, but the name on the label changes, and in the EU and UK the brand owner who puts a product on the market under their own name is treated as the manufacturer with the legal duties that come with it.
- 2Typical fix: the test lab issues a report extension or a letter adding your brand and model name as an alias for the tested model, with no change to the product. North American listings often list brand names as variants under the same file.
- 3Any change that touches safety — electrical design, key components, enclosure or protective firmware — needs a review and maybe retests. Cosmetic changes (logo, colour) usually do not, but the lab decides.
- 4Plan the documents: declaration of conformity in your name, technical file, labels with your name and address, manuals in the right languages and an economic operator in the EU.

Short answer: a certificate belongs to a product, a manufacturer and a model name. When you rebrand, ask the lab to add your brand and model name to the report or listing; cosmetic changes usually need no retest, but safety-related changes do. In the EU and UK the brand owner takes on the manufacturer’s duties. Get this agreed before you order.
What changes with your brand
| Item | Before | After rebranding |
|---|---|---|
| Name on the product and label | Factory brand and model | Your brand and model name |
| Test report and certificates | Factory name | Alias or extension adding your names |
| EU/UK declaration of conformity | Factory | In your name if you are the manufacturer on the market |
| Technical file | Factory | You hold or have access to it |
| EU economic operator | Importer or representative | Same rule applies; your name may be on the label |
| NRTL listing (North America) | Factory file | Private-label listing or variant |
| Manuals and packaging | Factory | Your content, in required languages |
The usual route
- Choose a certified base model with test reports from an accredited lab.
- Ask the lab for an alias or extension: a letter or revised report that lists your brand and model name as identical to the tested model.
- Prepare the declaration of conformity in your name with the standards listed, signed by a person with authority.
- Compile the technical file: reports, drawings, parts list, user manual, risk assessment. If the factory keeps the confidential parts, agree access terms.
- Update labels: brand, model, ratings, address, mark placement, serial number format.
- Check market extras: UKCA, RoHS, WEEE, battery and packaging rules, local approvals — see importing into the EU and UK and importing into the US.
Changes that need review or retest
| Change | Usually needs |
|---|---|
| Logo, colour, packaging | Check only; the lab decides |
| New plastic or paint | Material data (UV, flammability) |
| Different cable or plug | Cable report or test of the connector assembly |
| Different relay, RCD, meter or board | Critical-component update; possible retest |
| Firmware changes to protection, metering or communication | Software review; possible retest |
| Housing shape change | Mechanical and ingress tests |
| New radio module | Radio and cybersecurity assessment — see cybersecurity |
When in doubt, ask the lab for a written opinion before production.
Who holds what
| Document | Who should hold it |
|---|---|
| Test reports and CB certificate | Factory, with copies for you; ask for the lab’s contact |
| Declaration of conformity | You (as the brand owner), with the factory’s support |
| Technical file | You or accessible to you on request |
| NRTL listing file | Factory, with your private-label listing agreed |
| Firmware and app licence | Agreed in the contract — see firmware and app ownership |
Contract clauses to add
- The factory maintains the certificates for the models and informs you of any change that may affect them.
- No change to certified critical components without your approval.
- The factory provides test reports, lab contacts and documents within a set time.
- Cost split for alias and extension fees.
- Responsibility for non-conformity found in market surveillance.
Check the certificates
Use the checks in how to verify a certificate before you rely on a report; confirm the report number with the lab and that your model is covered.
VULTAE
VULTAE’s chargers are certified per market configuration — CE, UKCA and TÜV for IEC versions, ETL and ENERGY STAR for North American versions — and certificates are issued for specific models. For a branded model, we discuss your market and brand at the brief stage and advise what is needed. See the OEM / ODM page and what you can customise.
Questions buyers ask
- Does my brand name appear on the factory’s certificate?
- Not automatically. Ask the test lab or certification body to add your brand and model name to the report or listing as an alias or variant of the tested model. That is a standard service; fees and time depend on the lab.
- Who is the manufacturer in the EU if I put my brand on an OEM product?
- Under EU product rules, a company that places a product on the market under its own name or trademark is treated as the manufacturer, with duties for the declaration of conformity and technical documentation. Check the rules with your adviser or the market surveillance authority.
- Do I need new tests if I only change the logo and colour?
- Often not, but confirm with the test lab. Colour can affect UV and flammability ratings of plastics; a new coating or material may need data from the supplier.
- What about North American listings?
- Listings by an NRTL such as ETL list the model and the applicant; a brand owner can often be added as a private-label under the factory’s file after an agreement with the lab. Ask the lab about private-label listing.
