Battery EPR costs are rarely “just a compliance fee”. In most EU countries, Battery Extended Producer Responsibility fees are designed to finance the full end-of-life system – collection, safe handling, transport, treatment, recycling, and scheme administration. What you pay is therefore a function of what you place on the market and how the national scheme prices that end-of-life chain.
This blog breaks down the real cost drivers behind Battery EPR fees and the practical levers that reduce cost without creating compliance risk. It also shows how requirements differ across countries, with concrete examples from Belgium, the Netherlands, and France and published tariff examples for 2025 to illustrate the mechanics.
Why Battery EPR fees vary so much across countries?
Battery EPR is shaped by EU-level principles, but implementation is national. Each country or scheme decides:
- How batteries are categorised and which streams are in scope
- Whether fees are charged per kg, per battery, or using a hybrid model
- How granular chemistry reporting must be
- What “battery weight” means for packs and assemblies
- Which special categories exist (for example, energy storage systems or e-bike batteries)
- Whether minimum annual contributions apply
The result: the same battery placed on the market in three countries can produce three very different invoices – even when the total kilograms are identical.
What Battery EPR fees typically finance?
Most producer fees fund a combination of:
- Collection infrastructure (drop-off points, retailer take-back, municipal systems)
- Sorting and safe handling, especially for lithium batteries
- Transport to approved facilities
- Treatment and recycling operations
- Reporting, auditing, compliance checks, and scheme administration
- In some systems, awareness and consumer communication costs
Key takeaway: your EPR fee is a proxy for the end-of-life cost the country needs to recover, not a flat compliance tax.
The real cost drivers that decide your invoice
1) Weight – the most direct driver in many countries
Where fees are charged per kg, your costs scale directly with weight placed on the market. Even in “per unit” systems, the unit fee is often tied to a weight band, which means weight still determines what you pay.
The practical risk is that companies overpay because battery weights in BOMs, SKU masters, or declarations are wrong or not aligned to the scheme definition:
- Pack weight vs cell weight confusion
- Outdated weights after design changes
- Supplier substitutions not reflected in master data
- “Average weights” used across product families that hide outliers
If you overstate weight by 10 percent, you often overpay by roughly 10 percent every year. This is one of the most common, preventable Battery EPR cost leaks.
2) Chemistry – because treatment complexity and safety risk differ
Chemistry can drive cost because:
- Safety and fire risk changes collection and logistics controls
- Sorting and processing routes differ
- Recovery yields and residues differ
- Schemes may explicitly differentiate tariffs by chemistry
Some countries price chemistry very explicitly. France’s tariff table, for example, uses different €/kg rates for different battery chemistries and subcategories. Belgium and the Netherlands commonly require chemistry mapping alongside weight bands for many portable batteries.
If your chemistry mapping is weak, organisations often default to a “safe” conservative category. That may feel low-risk, but it can cause persistent overpayment and can still create audit exposure if the classification is incorrect.
3) Collection and handling obligations – the hidden driver behind tariff levels
Even if the producer never touches physical returns, the producer finances collection and treatment through the scheme. Costs tend to rise when:
- The stream is hard to collect (small consumer batteries are dispersed and expensive)
- The country is enforcing higher collection targets or expanding take-back infrastructure
- Additional safety requirements apply (lithium risk drives higher handling and transport controls)
- Special streams exist (ESS or large industrial batteries with distinct risk profiles)
In other words, the fee is not only about what you sell – it reflects what the national system must fund.
Where companies silently overpay?
Recurring overpayment patterns seen across battery portfolios:
- Wrong battery category mapping (portable vs industrial vs other national substreams)
- Wrong battery weight per unit in ERP or BOM
- No consistent method to handle embedded batteries across countries
- Double counting due to multiple legal entities or channels reporting the same volumes
- No control over supplier chemistry substitutions that change tariff mapping
- Weak audit trail on how declared quantities were derived
Fixing these issues often reduces fees and reduces enforcement risk at the same time.
Country examples: how data requirements and fee logic differ
Belgium – Bebat
Belgium’s Bebat contribution tables use detailed pricing structures. For many portable batteries, fees are per battery and depend on weight band and chemistry. Some categories are priced per kg, especially in heavier ranges and specific lithium categories. Bebat also publishes distinct tariffs for energy storage systems, priced per kg for defined installation limits.
What this means for your Belgium data model:
- Chemistry mapped to Bebat tariff families
- Accurate unit weights to land in the correct weight band
- Units placed on the market (not only kilograms)
- If you sell ESS, the ESS classification and reporting logic must match Bebat categories
Published tariff examples (as per public 2025 tables):
- Lithium rechargeable 0–50 g: 0.080 € per battery
- Lithium rechargeable 51–150 g: 0.180 € per battery
- Lithium rechargeable 151–500 g: 0.550 € per battery
- Lithium primary over 2 kg to 25 kg: 3.200 € per kg
- Lithium rechargeable ESS installation up to 16 MWh: 2.890 € per kg
Netherlands – Stichting OPEN
The Netherlands uses a similar “per battery by weight band and chemistry” approach for many batteries. However, Stichting OPEN highlights an operational difference that catches organisations in practice:
- If a battery pack does not have a shock-resistant casing (for example, visible cells in a shrink tube), declaration may need to be based on number of cells, chemistry system, and weight per cell rather than only pack-level information
This changes the reporting dataset requirement: some organisations need pack construction attributes or a rule-based decision on whether reporting can be “pack weight” or must be “cell level”.
Published tariff examples (as per public 2025 fee list):
- Lithium or lithium-ion batteries up to 50 g: 0.036 € per battery
- E-bike industrial lithium-ion batteries: 1.172 € per kg
France – ecosystem
France’s ecosystem tariff table is structurally simpler in many cases because it applies €/kg rates by chemistry category. You still need robust chemistry mapping and mass allocation, but you typically do not need the same per-unit weight band logic as Belgium or the Netherlands.
Published tariff examples (as per public 2025 tariff table):
- Alkaline batteries: 0.350 € per kg
- Saline batteries: 0.700 € per kg
- Lithium batteries sticks and button: 2.350 € per kg
- Lithium-ion with cobalt (for example LCO or NMC): 0.470 € per kg
- Lithium polymer without cobalt (for example LMO, LFP, LTO): 0.500 € per kg
- Minimum annual contribution: 200 € excluding VAT
Worked example: the same battery, three different country outcomes
Assume a common scenario:
- Lithium-ion rechargeable battery used in consumer electronics
- Battery weight per unit: 40 g (0.04 kg)
- Annual volume placed on the market: 100,000 units
France – ecosystem model (€/kg by chemistry)
- Total mass: 100,000 × 0.04 kg = 4,000 kg
- If classified as lithium-ion with cobalt at 0.470 € per kg
- Estimated contribution: 4,000 × 0.470 = 1,880 €
- Plus check minimum annual contribution rules
Belgium – Bebat model (per battery by weight band)
- 40 g falls into the 0–50 g lithium rechargeable band at 0.080 € per battery
- Estimated contribution: 100,000 × 0.080 = 8,000 €
Netherlands – Stichting OPEN model (per battery by weight band)
- Up to 50 g lithium or lithium-ion at 0.036 € per battery
- Estimated contribution: 100,000 × 0.036 = 3,600 €
What this illustrates:
- Fee basis matters as much as weight
- Per kg systems can look cheaper for small batteries compared to per unit band systems
- You need a reporting dataset that supports both kg-based and unit-band logic across countries
How to reduce Battery EPR fees safely: levers that work in the real world?
Build a scheme-ready battery master dataset
A practical minimum dataset that supports most EU reporting models includes:
- Country of placing on the market
- Obligated entity and channel logic to avoid double reporting
- Battery category per SKU (portable, industrial, EV, SLI, plus national substreams)
- Chemistry mapping aligned to each scheme’s tariff groups
- Unit weight and, where required, weight band assignment rules
- Pack construction rule flags where relevant (for example NL pack vs composed battery logic)
- Evidence flags for deductions where the country allows them (exports, returns, specific exemptions)
Fix the top SKU contributors first
Battery portfolios are typically Pareto-distributed. Cleaning chemistry and weight for the highest-volume SKUs produces immediate impact, then you scale the method across the long tail.
Stop conservative misclassification
“Conservative” often means “expensive and still incorrect”. The safe route is documented classification with evidence and decision rules – not defaulting to higher-fee categories.
Implement reconciliation controls
Simple operational controls prevent recurring overpayment:
- Reconcile sold units vs reported units by country and period
- Reconcile BOM weight vs declared weight and flag outliers
- Monitor chemistry drift caused by supplier substitutions
- Lock EPR master fields so weights and chemistry are controlled changes, not casual edits
Align design changes to reporting immediately
You only realise cost reduction from lighter packs or chemistry changes if:
- BOM and master data are updated
- Tariff mapping tables are updated
- Reporting extracts pull the new attributes for the correct reporting period
Many companies do the engineering change and keep paying the old reporting data for one to two years.

FAQs
What is the single biggest driver of Battery EPR cost?
In many countries it is weight, because fees are charged per kg or weight band. The biggest hidden driver is data quality – wrong weights and wrong classifications create persistent overpayment.
Do all countries require chemistry details?
Not all, but many schemes differentiate tariffs by chemistry or require chemistry category declarations. Even where tariffs do not differ, chemistry can affect handling requirements and scheme categorisation.
Why do Belgium and the Netherlands look more complex than France?
Belgium and the Netherlands commonly use per-unit fees by weight band with chemistry columns, which requires unit-level mapping. France commonly uses €/kg by chemistry, which is structurally simpler but still depends on correct chemistry allocation and mass data.
Can I reduce fees just by choosing a cheaper chemistry?
Only if the scheme tariff logic differentiates that chemistry and your product and safety requirements allow it. Chemistry changes also increase reporting complexity if you cannot track chemistry at SKU level.
What minimum data should I maintain for multi-country battery reporting?
At minimum: units by country, category, chemistry mapping, and weight per unit. For some countries, you also need pack construction rules or cell-level detail for certain pack types.
Are the rates in this blog the official EU rates?
