| Publication | 17 August 2026 |
| Entry into force | Not specified in the regulation |

If you manufacture, import or distribute electric vehicles or plug-in hybrids in Europe, this regulation requires you to review your homologation process. The UN Regulation No. 100, adopted under the Geneva Agreement of 1958 and incorporated into the European Union legal framework with reference CELEX:42026X1695, establishes the uniform technical standards that vehicles must comply with regarding their electric powertrain. Its publication on 17 August 2026 makes these requirements a mandatory condition for accessing the European market.
The standard is not a technical recommendation: it is the binding homologation framework. Without certification in accordance with this regulation, an electric vehicle or plug-in hybrid cannot be legally marketed in the EU.
What does this regulation establish?
UN Regulation No. 100 sets uniform technical provisions for vehicle homologation in relation to their electric powertrain. The three technical pillars it regulates are:
- Safety requirements of the electric propulsion system
- Performance requirements of the powertrain
- Technical tests that vehicles must pass to obtain homologation
The types of vehicles covered by the standard are:
- Battery electric vehicles (BEV)
- Plug-in hybrid vehicles (PHEV)
A key element of this standard is its international dimension: being developed under the Geneva Agreement of 1958, the signatory countries of that agreement mutually recognize homologations granted in accordance with this regulation. This means that a homologation obtained in one signatory country is valid in all others, which facilitates access to multiple markets with a single certification process.
Incorporation into the EU legal framework means that the national homologation authorities in each Member State must adapt their certification procedures to align with these uniform standards.
Economic and operational impact
The impact of this regulation translates into two main dimensions for companies in the sector:
| Dimension | Concrete impact | Who bears it |
|---|---|---|
| Homologation process | Obligation to certify the electric powertrain in accordance with the tests and requirements of UN Regulation No. 100 | Manufacturers of electric vehicles and PHEV |
| Access to the European market | Without homologation in accordance with this regulation, the vehicle cannot be marketed in the EU | Manufacturers and importers |
| Adaptation of procedures | National authorities must update their certification systems | Homologation bodies in each Member State |
| Importers from third countries | Must obtain homologation in accordance with the regulation to access the EU market | Importers and distributors of vehicles from outside the EU |
| Opportunity for mutual recognition | A single homologation can be valid in all countries signatory to the Geneva Agreement of 1958 | Manufacturers with export ambitions |
From an operational perspective, companies that already have previous homologations will need to verify whether these comply with the new standards of UN Regulation No. 100 or whether a new certification process is necessary.
Who does it affect?
- Manufacturers of battery electric vehicles (BEV) wishing to market in the EU
- Manufacturers of plug-in hybrid vehicles (PHEV) with presence in the European market
- Importers of electric vehicles and hybrids from third countries (China, South Korea, USA, etc.)
- Distributors of electric vehicles operating in the EU market
- National homologation authorities of EU Member States, which must adapt their certification procedures
- Laboratories and technical bodies responsible for conducting homologation tests
Practical example
A Spanish importer of electric vehicles manufactured in China wishing to introduce a new model to the European market in 2026 must ensure that the vehicle has homologation in accordance with the UN Regulation No. 100 before beginning its commercialization.
If the Chinese manufacturer has already obtained homologation in a country signatory to the Geneva Agreement of 1958, that certification will be mutually recognized in the EU, eliminating the need to repeat technical tests in Europe. The importer, in that case, will only need to verify that the homologation documentation is in order and present it to the national homologation authority of the Member State where it will market the vehicle.
If, on the other hand, the manufacturer does not have homologation in accordance with this regulation, the importer will not be able to register or sell the vehicle in the EU until the certification process is completed, which can result in significant delays in market launch.
What should companies do now?
- Audit current homologations: Review whether the electric vehicles or plug-in hybrids you market already have certification in accordance with UN Regulation No. 100. If not, start the process as soon as possible.
- Verify the homologation status of suppliers and manufacturers: If you are an importer or distributor, confirm with the manufacturer whether their models are homologated under this regulation before closing new import contracts.
- Contact the national homologation authority: Consult with the competent body in your Member State (in Spain, the General Traffic Directorate and the Ministry of Industry) to learn about the updated timelines and procedures in accordance with the new regulation.
- Review distribution contracts and commercial agreements: Include clauses that guarantee compliance with UN Regulation No. 100 by the manufacturers you work with.
- Take advantage of mutual recognition: If your company operates in several countries signatory to the Geneva Agreement of 1958, plan your homologation strategy to obtain a single certification valid in all those markets and reduce costs.
Frequently asked questions
What vehicles must comply with UN Regulation No. 100 to be sold in the EU?
Battery electric vehicles (BEV) and plug-in hybrid vehicles (PHEV). The regulation applies specifically to the requirements of the electric powertrain: safety, performance and associated technical tests.
When does this regulation come into force for manufacturers and importers?
The regulation was published on 17 August 2026. The entry into force date is not specified in the available regulatory text. It is essential to consult the full text on EUR-Lex or contact the national homologation authority to learn the exact application timelines.
Does an importer of electric vehicles from China need to repeat homologation tests in Europe?
Not necessarily. If the manufacturer already has homologation in accordance with UN Regulation No. 100 obtained in a country signatory to the Geneva Agreement of 1958, that certification is mutually recognized in the EU. The importer must verify that the documentation is in order and present it to the competent national authority.
What must national homologation authorities do?
The national homologation authorities in each EU Member State must adapt their certification procedures to align with the uniform technical standards established by UN Regulation No. 100. This includes updating the evaluation processes for safety, performance and tests of the electric powertrain.
What advantage does mutual recognition under the Geneva Agreement of 1958 offer?
Mutual recognition allows a homologation obtained in a country signatory to the Geneva Agreement of 1958 to be valid in all other signatory countries, including EU Member States. This represents a significant reduction in costs and time for manufacturers with an international commercialization strategy, by avoiding duplicating certification processes in each market.
