Supply chain & supplier data
Create clear data requests and keep evidence, ownership, and change history connected.
Make information requests specific
A broad request for “passport data” is difficult for a supplier to answer. Use a field register with definitions, units, source expectations, and a named contact for questions.
Useful starting points
- Agree on field definitions and evidence references.
- Track incomplete or inconsistent responses.
- Document how a supplier will communicate changes.

Chain of custody records
Chain of custody records show the unbroken sequence of holders, transfers, and transformations for a quantity of material, so the quantity in a battery can be traced to its origin.
Cobalt and lithium chain evidence
Cobalt and lithium chain evidence is the traceable record from extraction through refining to cell production, with origin, quantity, and chain of custody stated for each stage.
Due diligence duty explained
The due diligence duty in Regulation (EU) 2023/1542 requires a documented policy, a management system, risk work, verification, and public reporting for specified raw materials.
Due diligence for small operators
Small operators face the same evidence test in proportion to size and leverage, and the record should show a proportionate system, a clear scope decision, and honest gaps.
Due diligence vs passport data distinction
Due diligence data and passport data overlap but are not identical, and each record must state its own scope, period, and access level without merging the two.
Gaps and missing supplier data
A gap is a named piece of missing supplier data with a reason, an owner, and a next step, and the record must show gaps openly instead of filling them by assumption.
Nickel and graphite chain evidence
Nickel and graphite chain evidence follows each material from mine to refiner or processor to anode or cathode production, with grade, form, and quantity recorded at each transfer.
Risk identification in the chain
Risk identification is the evidence based process of finding red flags, gathering facts about them, and assessing severity, likelihood, and leverage before any response is chosen.
Risk mitigation evidence
Risk mitigation evidence is the dated record of the action chosen for an identified risk, the owner and deadline, and the follow up measure that shows whether the action worked.
Which Raw Material Suppliers Share Full Composition Statements?
No published comprehensive list identifies which raw material suppliers share full composition statements, and this guide describes what a full statement contains and how to request and record a supplier response.
Supplier data collection
Supplier data collection is the planned gathering, checking, and retention of evidence from each supplier, with a named request, a deadline, and a record of what arrived.
Supplier declarations vs verified evidence
A supplier declaration is a statement by a supplier, while verified evidence is a statement tested by an independent check, and the record must keep the two kinds separate.
Supply chain mapping
Supply chain mapping turns a supplier list into a traceable chain from extraction to pack assembly, with each tier, function, and gap recorded and dated.
