A supplier pack is most useful when the buyer can tie every important statement to a physical lot, source record and review status. The aim is to ask better questions, not to demand a larger pile of PDFs.
Start with the material and consignment
Ask for the material description, grade, lot identifiers, quantities and units, dispatch reference and the receiving location. Check whether identifiers on certificates and delivery documents resolve to the same physical lot.
Request evidence by claim
For composition or specification, ask for the assay, method and sampled lot. For origin or transformation, ask for the relevant upstream statement and chain of recorded events. For responsible-sourcing diligence, use an appropriate risk-based process such as the OECD minerals guidance; a lot trail alone does not answer human-rights or environmental questions.
- Claim and exact lot scope
- Source document and issuer
- Measurement or declaration basis
- Review date, version and open exceptions
Check what is missing
A missing upstream transformation, uncertain sample link or quantity discrepancy should be visible in the pack. Ask the supplier to state whether the link is confirmed, reported or unknown. Keep the gap open until new evidence supports resolution.
What this looks like in practice
A cathode-material buyer receives an assay and a shipping note. Both name lot P-22, but the process certificate names P-21. Rather than assuming a typo, the buyer asks for the lot mapping or a corrected, versioned certificate.
This checklist does not establish regulatory compliance, responsible sourcing or material conformity. Those require separate assessment against applicable requirements.
