Overview

Battery passport and due diligence rules for Bangladesh

Batteries are becoming one of the most regulated products in international trade. The EU Batteries Regulation sets rules for the whole life cycle of batteries sold in the European Union, from raw material sourcing and carbon footprint to labelling, performance, collection and recycling. From February 2027, many larger batteries will need a battery passport: an electronic record, accessible through a QR code, holding information about the battery's composition, origin, performance and sustainability. We help Bangladeshi manufacturers, assemblers, importers and exporters understand these duties as part of our trade and regulatory practice in Bangladesh.

The passport requirement applies to light means of transport batteries, such as those used in electric bicycles and scooters, to industrial batteries above a capacity threshold and to electric vehicle batteries placed on the EU market. Other batteries face labelling and marking duties without a passport. The economic operator placing the battery on the market is responsible for the passport, but much of the data must come from cell makers, material suppliers and component manufacturers. Bangladeshi companies supplying batteries, battery packs or products containing them to European buyers should expect detailed battery passport data requests well before 2027.

Due diligence obligations add a further layer. The Regulation requires certain operators to establish due diligence policies for cobalt, lithium, nickel and natural graphite, identify and address social and environmental risks in their supply chains and have their systems verified. After the European Union postponed these obligations to 2027, businesses have more time, but the work involved is substantial and buyers are already asking suppliers about sourcing. Recycled content, carbon footprint and performance requirements are being phased in through further implementing measures, so the requirements will continue to evolve over the coming years and should be monitored.

In Bangladesh, battery manufacturing, assembly, trading and recycling are growing, driven by the lead-acid battery industry, electric three-wheelers, solar systems, telecom back-up and the early lithium-ion sector. Domestic rules on hazardous waste, e-waste, environmental clearance, product standards and imports apply to batteries, and used battery handling has been a significant environmental concern. A business that exports batteries or battery-containing products must therefore satisfy both domestic rules and the requirements of its export markets. We help clients see where these overlap and build one coherent record system rather than separate, inconsistent processes for each market.

Our work combines regulatory analysis, supply-chain contracts, data governance and disputes. We map which rules apply to each product, design supplier data and due diligence obligations, review buyer requirements, advise on the Personal Data Protection Act 2026 where records include personal information, and help structure relationships with technology providers that host and manage passport data. We work with technical consultants and EU counsel on battery passport standards, conformity assessment and carbon footprint questions. Where disputes arise over rejected products or supplier data, our dispute resolution team handles negotiation, arbitration and court proceedings.

01

Applicability and product mapping

We review your battery products, battery-containing goods and export markets to confirm which categories fall under the EU Batteries Regulation, which require a battery passport and which carry other obligations such as labelling, marking or removability. We also identify the economic operator for each sale, because the answer determines who must hold data, sign declarations and take responsibility before EU authorities, and we set out a timetable for each obligation.

02

Passport data and record architecture

We help design the record structure behind a battery passport, identifying the required data fields, the supplier responsible for each, verification steps, access rights for different users and update procedures. We review contracts with passport platform providers covering data hosting, security, availability, ownership, confidentiality and continuity, so that information remains accessible for the long period the Regulation requires, even if a provider changes or a business is sold, restructured or closed.

03

Raw material supply-chain due diligence

We help operators prepare due diligence policies and management systems for cobalt, lithium, nickel and natural graphite in line with the Regulation and recognised international guidance. That includes supplier questionnaires, risk assessment, escalation and remediation steps, grievance mechanisms and preparation for third-party verification. For Bangladeshi suppliers, we focus on providing upstream buyers with reliable information without promising more than their own suppliers can deliver, and on keeping records that support each answer.

04

Supplier and buyer contracts

We draft and negotiate supply agreements with cell makers, chemical and material suppliers and component manufacturers that require timely, accurate data, allow verification, protect confidential information and allocate liability for errors. On the sales side, we review buyer requirements and negotiate proportionate obligations, cost sharing for testing and data work, and remedies that reflect the exporter's actual control over the information involved and the battery passport data it supplies.

05

Domestic compliance and end of life

We advise on Bangladeshi rules affecting battery manufacturing, assembly, import and recycling, including environmental clearance for manufacturing and recycling facilities, hazardous waste and e-waste duties, product standards, import conditions and take-back arrangements. We also help exporters understand EU extended producer responsibility for batteries, which is usually borne by the producer in the EU market but affects data, labelling and contract terms for Bangladeshi suppliers and their products.

06

Audits, rejections and commercial disputes

When a buyer audits a supplier, an EU authority questions a product or a shipment is rejected for missing data or non-compliance, we review the requirements, the contract and the evidence and prepare the response. We pursue claims against suppliers whose data proved inaccurate, defend exporters against disproportionate chargebacks and act in arbitration or court where negotiated solutions are not possible, protecting the client's commercial relationships wherever we can.

01

Which batteries will need a battery passport under EU law?

The passport requirement under the EU Batteries Regulation applies to light means of transport batteries, industrial batteries above the capacity threshold set by the Regulation and electric vehicle batteries, when placed on the EU market or put into service from February 2027. Portable batteries in consumer devices generally do not need a passport, though they face other requirements such as labelling and, in time, removability. If you export battery packs for electric bicycles, scooters, energy storage or vehicles, a passport is likely to be needed. We review your products against the definitions to confirm the position.

02

Who is responsible for creating a battery passport?

The economic operator that places the battery on the EU market or puts it into service is responsible for the passport. That is usually the manufacturer or, for products made outside the EU, the importer or another party established in the EU. A Bangladeshi exporter will not normally hold the legal duty itself unless it places products on the market directly through an EU entity, but it will almost certainly be asked to provide data. We clarify the roles in each sales channel and draft contracts setting out exactly what information the Bangladeshi party must supply.

03

What information does a battery passport contain?

A battery passport holds general information about the manufacturer and the battery model, material composition including hazardous substances and critical raw materials, carbon footprint information, recycled content, performance and durability data, information on supply-chain due diligence, and details relevant to repair, repurposing and recycling. Some information is public, while some is restricted to authorities or to persons with a legitimate interest. The exact content is being refined through implementing measures and standards. We help clients map each data field to its source and set up processes to collect, verify and update it throughout the product's life.

04

Do the EU raw material due diligence obligations apply directly to Bangladeshi suppliers?

The legal obligations fall on economic operators placing batteries on the EU market above a turnover threshold, not directly on Bangladeshi suppliers. However, those operators must assess risks throughout their supply chains and will require information and commitments from suppliers, including Bangladeshi assemblers, pack makers and component manufacturers. The obligations were postponed and are now expected to apply from 2027. We help Bangladeshi suppliers prepare credible responses, policies and records, and negotiate contract terms that reflect the information they can realistically provide from their own upstream suppliers in China, India and other countries.

05

Are lead-acid batteries made in Bangladesh for export affected?

Yes, in several ways. Lead-acid batteries sold in the EU must meet the Regulation's requirements on substances, labelling, collection and producer responsibility, and industrial or vehicle batteries above the relevant thresholds may also need a battery passport depending on their category and use. Domestically, lead-acid battery manufacturing and recycling are subject to environmental clearance and hazardous waste controls, and improper informal recycling has caused serious pollution and public health concerns. We advise lead-acid battery manufacturers and recyclers on both export requirements and domestic compliance, including the records needed to demonstrate responsible end-of-life handling.

06

How should commercially confidential data be protected in a battery passport?

The Regulation separates information that must be publicly accessible from information available only to authorities or persons with a legitimate interest. Even so, many suppliers worry, with some justification, that composition, sourcing and performance data could reveal trade secrets or allow customers to bypass them. Contracts with buyers and passport platform providers should define access rights, permitted use, security standards, retention and what happens to data when the relationship ends. We draft these provisions and advise on balancing regulatory transparency with legitimate confidentiality, so that suppliers can participate without losing their competitive position.

07

Does Bangladesh have its own battery passport requirement?

There is currently no Bangladeshi battery passport requirement equivalent to the EU rules. Domestic regulation of batteries focuses on environmental clearance, hazardous waste and e-waste management, imports, product standards and workplace safety. However, Bangladeshi exporters must comply with the rules of their export markets, and other countries are considering digital product passports and battery due diligence. Building a robust record system now prepares businesses for future domestic or foreign rules and strengthens their position with existing buyers. We monitor battery passport developments and advise clients when new requirements are likely to affect their products or markets.

08

What happens if battery passport data supplied by us turns out to be wrong?

Inaccurate data can lead EU authorities to take action against the economic operator, including requiring corrective measures, withdrawal or recall of products and penalties under national law. The operator will usually seek to recover its losses from the supplier that provided the faulty data. Bangladeshi suppliers should therefore make sure their contracts define data responsibilities clearly, include verification procedures and set reasonable limits on liability. We help draft these terms, investigate data errors, notify buyers where required and resolve claims, so that a battery passport error does not escalate into a costly dispute.

FAQ

Questions, answered.

Still unsure? Email info@trw.co with a short outline of the matter.

When does the EU battery passport requirement start to apply?
Under the EU Batteries Regulation, the passport requirement applies from 18 February 2027 to covered batteries placed on the market or put into service. Technical details are being developed through implementing acts and standards. Because supplier data systems take time to build, Bangladeshi exporters should begin preparing now rather than waiting for the final technical specifications. We help clients plan these steps in a realistic order, so that buyer requests can be answered confidently and the battery passport is ready when the first covered products ship.
What is a light means of transport battery under the EU rules?
It is a sealed battery used to power wheeled vehicles that can be driven by an electric motor alone or by a combination of motor and human power, such as electric bicycles and scooters, within weight limits set by the Regulation. Electric three-wheelers common in Bangladesh may fall into different categories depending on their specifications, so classification should be checked carefully. The category determines whether a battery passport is needed and which other obligations apply. We review technical specifications with engineers and give a clear view on classification for exporters considering European markets.
Does the Regulation require minimum recycled content in batteries?
Yes, in stages. Certain industrial, vehicle and light means of transport batteries will need documentation of recycled content for cobalt, lithium, nickel and lead, followed later by minimum recycled content levels. The detailed calculation and verification rules are set through implementing measures. Bangladeshi manufacturers should begin tracking recycled material inputs and obtaining supporting documents from suppliers now. Recycled content information will feed into declarations and the battery passport, so supplier contracts should require accurate documentation of the origin and proportion of recycled materials.
How does the battery passport relate to carbon footprint rules?
For electric vehicle batteries and certain other categories, the Regulation requires a carbon footprint declaration, followed by performance classes and maximum limits, on a timeline that depends on implementing acts. Carbon footprint information will form part of the battery passport. Calculating it requires data on energy use and materials from across the supply chain, including Bangladeshi manufacturing sites. We help suppliers understand what data buyers will request, how it should be documented and how contract terms should deal with errors, updates and the cost of calculation and verification.
Can a Bangladeshi company host its own battery passport data for buyers?
The economic operator is responsible for the passport, and many will use specialised platform providers. A Bangladeshi supplier may host its own data and share it with buyers or a platform, subject to the technical standards and the operator's requirements. We advise on the contracts, data security and Personal Data Protection Act 2026 issues raised by each approach, including access controls, backups, audit rights and what happens to battery passport data if the relationship with a buyer or platform ends.
Do used or second-life batteries imported into Bangladesh face restrictions?
Imports of used batteries and battery waste are restricted under import rules and hazardous waste controls, and may be subject to the Basel Convention when shipped across borders. Importers of second-life batteries for energy storage should confirm whether the batteries are products or waste under applicable rules before contracting, because classification determines the permits and documents required. Second-life projects also raise questions about warranties, safety testing and responsibility for eventual disposal, which should be addressed in the supply contract from the outset.
How long must battery passport records be kept?
The Regulation requires the passport to remain available for a long period, including after the battery has been repurposed or remanufactured, with responsibility passing to the operator that places the repurposed battery on the market. Contracts with platform providers and suppliers should therefore address long-term data retention, transfer and continuity if a business stops trading. We draft retention and transfer provisions so that battery passport obligations can be met for the full required period, whatever happens to the original provider or supplier.
