Economic operators under the Battery Regulation: who carries which duty

Almost every overview of the EU Battery Regulation explains what has to be done. The expensive question is who has to do it. Chapter VI answers it across nine articles and seven roles - and it has applied since 18 August 2024, two and a half years before the battery passport duty.

In brief
  • Duties attach to the act, not to the company sign. Whoever first makes a battery available on the Union market places it on the market and carries the weight. Everyone downstream verifies - and must not make it available while the check fails.
  • Chapter VI has applied since 18 August 2024. Article 96(2) puts the obligations of economic operators well ahead of 18 February 2027. Waiting for the passport deadline means the first part was already missed.
  • "Manufacturer" and "producer" are different roles. The regulation separates the product responsibility of the manufacturer (Article 3(1)(33)) from extended producer responsibility (Article 3(1)(47)), which can equally fall on an importer or a distributor.
  • Article 44 flips the role in three cases. Own brand, a modification that touches conformity, or a changed intended purpose: any one of them is enough, and the importer or distributor carries the full manufacturer obligations.
01 · Framework

Chapter VI has applied since 18 August 2024

The part of the regulation that hands out the roles has been in force for years. Its title is unwieldy, which is one reason it is rarely quoted.

Chapter VI of Regulation (EU) 2023/1542 is headed Obligations of economic operators other than obligations set out in Chapters VII and VIII and runs from Article 38 to Article 46. The exclusion in the title is literal: Chapter VII governs supply-chain due diligence, Chapter VIII waste batteries. Everything to do with the product itself - documentation, conformity, marking, traceability - sits in Chapter VI.

The timing is what matters. Article 96(2) applies the regulation from 18 February 2024 in general, but carves out Article 17 and the whole of Chapter VI and sets 18 August 2024 for both. Anyone importing batteries into the EU or distributing them here has been working under these rules for over two years - whether or not those batteries will ever need a passport.

02 · Roles

The seven economic operators of the Battery Regulation

Article 3(1)(22) lists five roles and then leaves a door open. Chapter VI actually addresses seven parties - and two of them are almost never counted.

Chapter VI: nine articles, seven addressees
  1. Art. 39Supplier of cells and modulessupplies

    You supply cells or modules to a manufacturer

  2. Art. 38Manufacturerplaces on the market

    You have batteries made and market them under your own name

    Definition 3 (1) 33
  3. Art. 41Importerplaces on the market

    You place a battery from a third country on the market

    Definition 3 (1) 64
  4. Art. 42Distributormakes available

    You make available without being manufacturer or importer

    Definition 3 (1) 65
  5.  End useruses
Roles beside the chain
Art. 40Authorised representative

You hold a written mandate from a manufacturer

Art. 43Fulfilment service provider

You warehouse, pack or dispatch other parties' batteries

Art. 45Second-life operator

You prepare for re-use, repurpose or remanufacture

Applies across the chain
  • Art. 44 Importers and distributors can become manufacturers
  • Art. 46 Every operator evidences supply and delivery for ten years
7 roles in Chapter VI
Duties attach to the act, not to the company type: supplying, placing on the market, or making available. Chapter VI has applied since 18 August 2024.

The definition of economic operator names the manufacturer, the authorised representative, the importer, the distributor and the fulfilment service provider, and adds "any other natural or legal person" carrying the relevant obligations. That clause is how the two overlooked roles arrive: suppliers of battery cells and modules (Article 39) and operators placing second-life batteries on the market again (Article 45).

Article 39 is the shortest article of the chapter and the most useful one for data collection: suppliers of cells and modules must provide the information and documentation needed to comply with the regulation, and they must provide it free of charge. Anyone currently negotiating whether material data sheets cost extra is negotiating over a statutory duty.

Article 45 is a reminder that a repurposed battery can fall into a different category than the original. Turning a vehicle battery into stationary storage places it on the market again, possibly as an industrial battery with everything that follows. More on that in battery recycling and recycled content.

03 · Terms

Manufacturer, producer, representative: three words, two traps

The regulation uses everyday words as separate legal terms. That is a deliberate split, and it is the source of most misunderstandings.

A manufacturer under Article 3(1)(33) is a person who manufactures a battery, or has one designed or manufactured, and markets it under its own name or trademark, or puts it into service for its own purposes. That is the product responsibility of Chapter VI.

A producer under Article 3(1)(47) is something else: the extended producer responsibility role, which by definition can be a manufacturer, an importer or a distributor. Article 42(2) makes the difference visible in a single sentence. Before making a battery available, a distributor must verify both that the producer is entered in the producer register under Article 55 and, separately, that manufacturer and importer have discharged their identification duties. Two checks, two terms, one paragraph.

And two different authorised representatives

Article 3(1)(63) defines the authorised representative who takes on product duties for a manufacturer. Article 3(1)(48) separately defines the authorised representative for extended producer responsibility. Two mandates, different content, different legal basis, often different service providers. In Germany the second sits in the Batterierecht-Durchführungsgesetz (BattDG), in force since 7 October 2025, under which the Umweltbundesamt entrusted stiftung ear with the authority's tasks.

The second trap hides in three terms that sound like synonyms. They decide who a duty lands on:

TermReferenceWhat it meansWho it typically hits
Placing on the marketArt. 3(1)(16)The first making available of a battery on the Union marketAn EU manufacturer, or the importer for third-country goods
Making available on the marketArt. 3(1)(17)Any supply for distribution or use in the course of a commercial activity, whether paid or freeAnyone downstream, typically the distributor
Putting into serviceArt. 3(1)(18)The first use in the Union for its intended purpose, without prior placing on the marketAnyone building for own use, for example in an own storage project

In practice: a company that builds a battery for its own storage project and never sells it has still put it into service under Article 3(1)(18). Article 38(1) names that case explicitly - "including for its own purposes". The obligations do not disappear because no sale takes place.

04 · Duties

Who carries which duty

The matrix is what the chapter actually says. It separates a duty you discharge from a duty you merely verify - a difference that decides liability.

Legend
  • own duty
  • verify it was done
  • falls on whoever places on the market
  • no duty
Ten duties from Chapter VI and Article 77 against four roles. A duty to verify is not a duty to perform - but it blocks placing on the market for as long as the check fails.

The manufacturer column is the densest, because Article 38 gathers the whole conformity workload there: draw up the technical documentation of Annex VIII, carry out or have carried out the conformity assessment of Article 17, issue the EU declaration of conformity under Article 18 and affix the CE marking under Articles 19 and 20. A ten-year retention duty follows from placing on the market or putting into service.

The importer column looks lighter than it is. Article 41(2) requires four checks before placing on the market, and paragraph 5 goes further: where the importer considers it appropriate in view of the risks, it carries out sample testing of batteries placed on the market, investigates complaints, keeps a register of complaints, non-conforming batteries and recalls where necessary, and keeps distributors informed. That is a quality function, not a checklist.

The distributor column looks thin and is the underestimated one. Article 42(1) requires due care, paragraph 2 requires four checks - among them a look at the producer register under Article 55, which no other role owes - and paragraph 3 forbids making the battery available until conformity has been restored. Selling a battery without a CE marking breaches Article 42 in its own right, whoever caused the original mistake.

For the authorised representative, Article 40(2) is the paragraph to read. It takes three things out of any mandate: the obligations of Article 38(1), the due diligence duties of Articles 48 to 52, and the duty to draw up the technical documentation. A representative can therefore keep the documentation available (paragraph 3(a)) but may not create it in your place. Buying a mandate does not buy conformity.

Which documents sit behind the rows "technical documentation" and "EU declaration of conformity", and which of them become passport content in their own right, is set out in which evidence the battery passport requires.

05 · Role switch

Article 44: when a distributor becomes the manufacturer

The shortest article of the chapter is the most expensive one. It is a single sentence with three letters - and it moves the entire load.

Article 44: when the role flips
  • Own name or own trademark

    The battery is placed on the market or put into service under that party's own name or trademark.

    Art. 44 a
  • Modification that touches conformity

    A battery already on the market is modified in a way that could affect compliance with the regulation.

    Art. 44 b
  • Changed intended purpose

    The intended purpose of a battery already placed on the market or put into service is changed.

    Art. 44 c
Three cases, worked through
Importer with an own brand
Own name or trademark

Conformity affected

Purpose changed

Considered a manufacturer, Article 38 applies in full

Distributor adding a second logo

Role unchanged, Article 38 does not bite

System integrator rebuilding a pack
Own name or trademark

Conformity affected

Purpose changed

Considered a manufacturer, Article 38 applies in full

The three conditions of Article 44 are alternatives. If one applies, the importer or distributor is considered a manufacturer and carries the full Article 38 obligations.

The three conditions are joined by "or". One is enough. The common case in practice is letter (a): the own brand. A company sourcing cells or packs from a third country and selling them under its own logo is not an importer with verification duties but a manufacturer with the full conformity workload - technical documentation, conformity assessment, declaration, CE marking, ten years of retention and, from 2027, the battery passport.

The line is finer than it sounds. The FAQ of the European engine manufacturers' association EUROMOT reads Article 44(a) as leaving the duties in place where an additional logo sits next to a manufacturer that remains identified and compliant; only where the importer or distributor alone appears on the battery does letter (a) bite. That is an association reading, not a legal act - but it describes exactly the point where the decision is made in practice.

Letters (b) and (c) hit system integrators

Fitting purchased modules into your own enclosure, swapping the BMS, or turning vehicle cells into a home storage unit modifies the battery and usually its intended purpose too. Both are in Article 44. The question then is no longer whether you are the manufacturer but whether your own documentation holds up. What non-compliance costs is set out in what happens in case of non-compliance.

06 · Passport

Article 77(4): the passport follows the placing on the market

For the battery passport the regulation names an act, not a role. That sounds like hair-splitting and decides in practice who is liable.

The wording is short: the economic operator that places the battery on the market must ensure that the information contained in the battery passport is accurate, complete and up to date. Read together with Article 3(1)(64) - the importer is the party that places a battery from a third country on the market - the answer follows by itself. An EU manufacturer that places its own batteries on the market owns the passport. A battery from a third country makes it the importer's. The EUROMOT FAQ reads it the same way.

For importers this is the least comfortable line in the chapter. They are liable for the accuracy of data they largely do not generate: chemistry, material composition, capacity values, dismantling information. Article 39 helps only one step, because it binds suppliers of cells and modules - not every supplier in the chain.

Article 77(7) draws the consequence for second life: for batteries prepared for re-use, prepared for repurposing, repurposed or remanufactured, the responsibility under paragraph 4 transfers to the economic operator that placed the battery on the market or put it into service. The original manufacturer is out, the repurposer is in.

When the passport becomes mandatory for which category is covered in battery passport obligation from 2027; how the passport then reaches the central EU registry is explained in registering a battery passport in the EU DPP registry.

07 · In Batteriepasswerk

What our product covers - and what it does not

Batteriepasswerk is battery passport software. It does not assign you a role - it carries the evidence for the role you already have.

One passport per unit, one owner
Mass serialisation via CSV or API, a GS1 Digital Link QR code per unit. Whoever places the battery on the market can say for every serial number which passport belongs to it and who maintains it.
Art. 77(4)
Collect supplier data without accounts
Suppliers fill in their figures through a self-service link, with no user account. Every value adopted keeps who supplied it and when - the information Article 39 already requires them to hand over free of charge.
Art. 39
Documentation findable for ten years
Declarations of conformity, test reports and data sheets sit as documents on the model, with expiry dates and reminders, hosted in Germany and versioned. Keeping available means being able to find it.
Art. 38(4), Art. 41(7)
A link to the system that knows the chain
Who you supplied lives in your ERP, not in the passport. REST API v1 with scoped keys and a test mode connects the two, so serial number, passport and delivery note mean the same unit.
Art. 46

What no software decides

Whether Article 44 applies is a legal assessment of your business model, not a setting in an account. The conformity assessment is done by the manufacturer or a notified body, and registration in the producer register under Article 55 runs per Member State through the national authority. What software can contribute is the evidence: the data, where it came from, and that it has not changed since.

How a data request to a supplier actually runs is shown on suppliers and supplier data. How every change stays provable is explained in audit trail and data integrity in the battery passport.

08 · FAQ

Frequent questions about economic operators

Who counts as an economic operator under the EU Battery Regulation?
Article 3(1)(22) names five roles explicitly: the manufacturer, the authorised representative, the importer, the distributor and the fulfilment service provider. It then adds any other natural or legal person subject to obligations relating to the manufacture, making available, placing on the market or putting into service of batteries. Through that clause Chapter VI also reaches suppliers of cells and modules and operators placing second-life batteries on the market again.
What obligations does an importer of batteries have?
Article 41 requires four checks before placing on the market: the EU declaration of conformity and technical documentation exist, the conformity assessment was carried out, the CE marking is affixed, and the manufacturer has given the model identification plus its name and address. The importer then adds its own name and postal address on the battery, protects storage and transport conditions, and keeps the declaration available for ten years.
When does an importer or distributor become the manufacturer?
Under Article 44 in three cases, which are alternatives rather than cumulative conditions: placing the battery on the market or putting it into service under its own name or trademark, modifying a battery already on the market in a way that could affect compliance, or changing the intended purpose of a battery already placed on the market. Any one of them triggers the full Article 38 obligations.
Who is responsible for the battery passport, the manufacturer or the importer?
Article 77(4) names an act rather than a role: the economic operator that places the battery on the market must ensure the information in the passport is accurate, complete and up to date. Where the manufacturer is established in the EU and places the battery itself, the duty is its own. Where the battery comes from a third country, it falls on the importer, because Article 3(1)(64) defines the importer as the party placing it on the market.
What is the difference between a manufacturer and a producer in the Battery Regulation?
They are two separate legal roles. The manufacturer under Article 3(1)(33) has batteries made and markets them under its own name - that is the product responsibility of Chapter VI. The producer under Article 3(1)(47) is the extended producer responsibility role and may itself be a manufacturer, importer or distributor. That role registers per Member State under Article 55.
Does a manufacturer outside the EU need an authorised representative?
Chapter VI does not require one: Article 40(1) says a manufacturer may appoint an authorised representative by written mandate. In practice the importer usually carries the product duties. Separately, Article 3(1)(48) defines an authorised representative for extended producer responsibility, and national law can require one - Germany does so in its Batterierecht-Durchführungsgesetz for producers without an establishment in the country.
Since when have the obligations of economic operators applied?
Since 18 August 2024. Article 96(2) applies the regulation from 18 February 2024 in general, but sets 18 August 2024 for Article 17 and for the whole of Chapter VI. The obligations of economic operators are therefore two and a half years older than the battery passport duty of Article 77, which starts on 18 February 2027.
