Importers cannot rely only on a supplier statement. Before placing a battery on the EU market, Article 41 requires importers to verify that the EU declaration of conformity and Annex VIII technical documentation have been drawn up, that the Article 17 conformity assessment has been carried out, that the battery bears CE marking, and that required marking, labelling, documents, instructions and safety information are present.

Distributors have a narrower but still concrete gate under Article 42. Before making a battery available on the market, they must verify producer registration, CE marking, required marking and labelling, required documents, instructions and safety information, and the manufacturer and importer identity details. If either actor has reason to believe the battery is non-conforming, it should not proceed until brought into conformity.

A useful Batteries Regulation conformity file should let a reviewer reconstruct the path from battery scope to CE marking. It should show the battery category, whether the product is series or non-series, which Article 17 module applies, which Articles 6 to 10 and 12 to 14 requirements are relevant, and whether Article 7 or Article 8 triggered notified body involvement.

The evidence file should also separate manufacturer evidence from importer and distributor checks. That prevents a downstream actor from treating CE marking as a substitute for verifying the declaration, technical documentation availability, labels, instructions, producer registration and identity details.

Start with the Member State where each battery category is made available on the market for the first time. Article 55 requires a producer register in each Member State, and producers may place batteries on that Member State market only if they, or their authorised representative where applicable, are registered there.

The registration file should identify the producer, battery categories and chemistries, and the measures used to meet extended producer responsibility and collection obligations. For portable and LMT batteries, the file should also explain the system used to keep reported data reliable.

The Batteries Regulation uses extended producer responsibility. Article 56 makes producers responsible for batteries they make available for the first time in a Member State, including batteries resulting from preparation for re-use, preparation for repurposing, repurposing, or remanufacturing.

Producer financial contributions cover separate collection, transport and treatment, compositional surveys where required, information on prevention and management of waste batteries, and data gathering and reporting to competent authorities. A producer responsibility organisation can carry out obligations on behalf of producers.

For portable batteries and LMT batteries, producers or their producer responsibility organisations must establish take-back and collection systems in the Member State where they make those batteries available for the first time. Those systems must cover the whole territory, taking account of population, expected waste battery volumes, accessibility, and proximity to end-users.

End-users must be able to discard waste portable batteries and waste LMT batteries at collection points without being charged, without having to buy a new battery, and without having to prove they bought the battery from the producer that set up the collection point.

For waste portable batteries, producers or producer responsibility organisations must attain and durably maintain collection targets of 45% by 31 December 2023, 63% by 31 December 2027, and 73% by 31 December 2030.

For waste LMT batteries, the targets are 51% by 31 December 2028 and 61% by 31 December 2031. The collection rate is calculated using the Annex XI methodology, which compares collected waste batteries with the average weight of relevant batteries made available on the market to end-users in the three preceding calendar years.

Collected waste batteries cannot be treated as disposal or energy-recovery material. Article 70 requires treatment in permitted facilities, with waste batteries removed from waste appliances, waste light means of transport, or end-of-life vehicles where applicable.

Article 71 requires permitted facilities to accept waste batteries made available to them and ensure preparation for re-use, preparation for repurposing, or recycling. Recyclers must meet Annex XII recycling efficiency and material recovery targets, calculated under the delegated methodology and documentation format for recycling efficiency and recovery rates.

Article 75 is the practical reporting checklist. Producers of portable and LMT batteries, or their producer responsibility organisations, must report annually by chemistry and battery category on placed-on-market amounts, collected waste batteries, collection rates, delivery to treatment, export for treatment or preparation, and delivery to preparation for re-use or repurposing.

Waste management operators, treatment operators, recyclers, and exporters also have reporting duties where they collect, treat, recycle, or export waste batteries. The evidence file should therefore connect sales data, collection data, treatment handovers, recycling calculations, and export records by Member State and battery category.

Article 7 covers electric vehicle batteries, rechargeable industrial batteries with a capacity greater than 2 kWh, and batteries for light means of transport (LMT). It distinguishes rechargeable industrial batteries with external storage from other rechargeable industrial batteries when setting application timing.

For those categories, the declaration and class are tied to each battery model per manufacturing plant. Teams should therefore map the battery category, model identifier, manufacturing plant, and whether the industrial battery has external storage before assigning an Article 7 workstream.

The sequence is cumulative. First, the covered battery model needs a carbon footprint declaration. Second, the battery bears a label declaring the carbon footprint performance class for that model and plant. Third, once the relevant delegated act sets maximum life-cycle carbon footprint thresholds, the technical documentation must show that the declared life-cycle carbon footprint value is below the applicable threshold.

That sequence matters because a class is not the same thing as a market-access threshold. Annex II says classes are based on the distribution of declared values for batteries placed on the market, with category A as the best class. Maximum thresholds are a later limit, set after information has been collected through declarations and class distribution and after a dedicated impact assessment.

Article 7 does not itself publish the calculation methodology, class boundaries, label formats, or maximum threshold values. It gives the Commission different tasks: delegated acts for the calculation and verification methodology, delegated acts for performance classes, implementing acts for the declaration and label formats, and delegated acts for maximum life-cycle carbon footprint thresholds.

The practical consequence is that teams should track four dependencies separately. A declaration format alone does not settle the calculation methodology, a calculation methodology alone does not set class boundaries, and a class delegated act does not necessarily mean the maximum-threshold requirement is already known.

Until the relevant class and threshold acts are available for the battery category, the useful evidence is the category and model analysis, calculation inputs, declaration fields, and change-control history. The regulation expects technical documentation to support the declared carbon footprint value and the class, including calculations and the evidence determining the input data.

Keep the evidence aligned to the model and plant. Annex II says the life-cycle carbon footprint calculation is based on the bill of materials, energy, and auxiliary materials used in a specific manufacturing plant for a specific battery model; sampling from different plants for the same model is not allowed, and a change in the bill of materials or energy mix requires recalculation.

Do not publish class boundaries, width of classes, or maximum threshold values unless the relevant delegated act for the battery category supports them. The regulation explains the factors the Commission must use, but it does not turn those factors into final numeric class boundaries in Article 7 itself.

Also avoid saying that carbon footprint classes alone determine market access. Under the Article 7 structure, the class label differentiates batteries by declared carbon footprint performance, while the later maximum life-cycle threshold is the requirement that the declared value must be below once the threshold delegated act applies.
