The duty sits with whoever places the battery on the EU market.
Not the cell maker in Asia. Not the distributor. The brand or importer whose name is on the declaration of conformity. CellHash is built for the three groups that carry that duty with the fewest people to discharge it.
E-bike and light-transport brands
About 1,200 companies sold 5.1 million e-bikes in the EU and UK in 2023. Most are brands and importers with packs sourced from Asia, low margin per unit and no compliance function. From 18 February 2027 each of those packs needs a passport before it can be placed on the market.
What is usually missing
- !Expected lifetime in cycles and test evidence per model.
- !Material composition, which sits with the cell supplier.
- !Dismantling information for packs bought as sealed units.
- !An item-level identifier scheme and QR artwork with lead time for pack tooling.
What CellHash does
- ✓Maps your bill of materials and supplier attestations to the 71 data points and names the gaps per model.
- ✓Issues item-level identifiers and QR codes in bulk for a production run, with label templates.
- ✓Registers and hosts every passport as authorised operator, so eIDAS onboarding is not your problem.
- ✓Starter plan priced for a brand, not an OEM. Under €500 a month.
Home and commercial storage makers
The EU installed 27.1 GWh of battery storage in 2025, up 45 percent: 9.8 GWh residential, 2.3 GWh commercial and industrial, about 15 GWh utility. A home battery is typically above 2 kWh, so residential and C&I systems are both in scope as industrial batteries.
What is usually missing
- !A clear view of which entity places each system on the market when integrators and installers are in the chain.
- !Performance and durability data in the conditional form the guidance expects for industrial batteries.
- !A route for state of health from the BMS into the item-level tier over the life of the system.
- !Hosting that survives the installer and the brand.
What CellHash does
- ✓Multiple models and facilities on one account, with the gap list per model and per tier.
- ✓BMS export ingestion with column mapping, so state of health lands in the passport without an integration project.
- ✓Legitimate-interest access management for installers, repairers and recyclers.
- ✓EU-resident hosting as authorised operator for the life of the system.
EU importers of non-EU cells and packs
Chinese makers held over half of the EU EV battery market in 2025, and nearly all LFP demand is imported. A non-EU maker cannot sell into the Union without an EU-hosted passport, and the liability for it sits with the importer or EU subsidiary whose name is on the paperwork.
What is usually missing
- !Recognition that the duty is the importer's, discovered late.
- !Supplier data in a form that maps to the Commission's data points rather than a spreadsheet per shipment.
- !An eIDAS-verified operator identity for the registry.
- !A hosting arrangement inside the Union that does not depend on the seller.
What CellHash does
- ✓Multi-entity accounts: one importer, many suppliers and brands, strict isolation between them.
- ✓Supplier intake by CSV and API with column mapping, so the data arrives once per model, not once per shipment.
- ✓Registration on your behalf as authorised operator, with proof of registration retained for customs questions.
- ✓AAS and Catena-X exchange for the OEM customers who ask for it.
UK exporters, recyclers, repairers and fleets
UK companies selling into the EU or Northern Ireland face the EU rules now and a Great Britain regime later. Recyclers, repairers, remanufacturers and fleet operators become legitimate-interest users of the same records once the access-rights act lands. Both groups use the record CellHash already hosts.
