EU Harmonized Standard for Batteries 2026: What Manufacturers and Importers Must Do

Key data

If you manufacture, import or distribute batteries or accumulators in the European Union, this standard directly affects you from 14 September 2026. Commission Implementing Decision (EU) 2026/2048 establishes the harmonized reference standard in support of Regulation (EU) 2023/1542, which sets the sustainability, safety and labeling requirements applicable to these products.

The mechanism is clear: complying with the harmonized standard is legally equivalent to complying with the essential requirements of the regulation. Failing to comply is not just a technical issue, it is an immediate market risk.

What does this regulation establish?

Decision 2026/2048 formally adopts the harmonized standard applicable to batteries within the framework of Regulation (EU) 2023/1542. This regulation is the European regulatory framework that establishes three major blocks of requirements for these products:

The harmonized standard adopted by this Decision acts as the technical "rule of the game": it defines exactly how these requirements are measured and verified. By following it, the company obtains the presumption of conformity, that is, it is legally presumed to comply with the regulation without the need for further demonstration to market surveillance authorities.

This greatly simplifies access to the European single market, especially for manufacturers operating in several EU countries or exporting from third countries to Europe.

Economic and operational impact

The impact of this standard is not only technical: it has direct consequences on the operations and commercial viability of companies in the sector.

• Access to the single market: Companies that can demonstrate compliance with the harmonized standard can market their products in all Member States without additional barriers. Those that do not can see their distribution blocked.
• Certification and documentation costs: Adapting certification processes and technical documentation to new harmonized standards involves investment in internal audits, laboratory testing and updating of technical files.
• Risk of market withdrawal: Non-compliance can result in product withdrawal from the European market, with the economic and reputational cost that entails: stock destruction, returns, loss of contracts and possible administrative sanctions.
• Competitive advantage: Companies that adapt quickly gain an advantage over competitors who have not yet updated their certification, especially in public procurement and contracts with major electric vehicle manufacturers.

The battery sector for electric vehicles and industrial storage is particularly sensitive, given the volume of investment underway and the regulatory scrutiny to which it is subject throughout Europe.

Who does it affect?

Decision 2026/2048 affects the entire value chain of batteries and accumulators in the EU:

• Manufacturers of batteries established in the EU or selling in the European market
• Importers who introduce batteries or accumulators from third countries into the EU market
• Distributors who market these products in any Member State
• Electric vehicle manufacturers that integrate batteries into their products
• Industrial storage companies that use or market large-capacity battery systems
• Technical advisors and compliance consultants who manage the certification of these products for their clients

Practical example

A Spanish importer bringing lithium batteries for electric vehicles from an Asian manufacturer must ensure that those batteries comply with the harmonized standard adopted by Decision 2026/2048. If the Asian manufacturer already has certification in accordance with this standard, the importer can rely on the presumption of conformity and market the product throughout the EU without additional procedures before each national authority.

If, on the other hand, the Asian manufacturer has not updated its certification to the new harmonized standard, the importer assumes the risk: market surveillance authorities in any Member State can order product withdrawal. This involves costs for returning merchandise, possible administrative sanctions and loss of contracts with European customers.

The practical solution is to require the supplier, before each order, to provide updated technical documentation that demonstrates compliance with the current harmonized standard under Regulation (EU) 2023/1542.

What should companies do now?

1. Identify if your products are within the scope: Check if you manufacture, import or distribute batteries or accumulators of any kind, including those for electric vehicles and industrial storage.
2. Review existing technical documentation: Check if your current technical file references the harmonized standard adopted by Decision 2026/2048. If not, update it.
3. Audit certification processes: Verify with your certification body or accredited laboratory whether the tests performed cover the requirements of the new harmonized standard.
4. Require updated documentation from suppliers: If you import, request from your suppliers the declaration of conformity and technical documentation aligned with the new standard before each import.
5. Update the EU declaration of conformity: Ensure that the declaration of conformity accompanying your products explicitly references Regulation (EU) 2023/1542 and the applicable harmonized standard.
6. Train your compliance and logistics team: Staff responsible for imports, quality and documentation must be aware of the new requirements to avoid errors in customs clearance and market audits.

Non-compliance can result in product withdrawal from the market or administrative sanctions, as established by the regulation itself. Do not wait for an inspection to act.
