Analytical criteria
State the chemical parameters and limits applicable to your intended category and market.
QUALITY / DOCUMENTATION
Quality you can discuss in measurable terms.
A grade name alone is not a complete buying specification. Share the limits, market constraints and documents that matter to your process.
Build the quality brief
COA / reference file
A reference certificate or specification sheet can make the target unambiguous.
Lot identification
Quality documents should relate to the lot being evaluated, with consistent references.
Traceability discussion
Ask which origin and process records can accompany the proposed supply.
EVIDENCE FIRST
A document is useful when it answers the buyer’s actual risk.
COA, certification, sampling and traceability are not decorative badges. Their relevance depends on the product, lot, destination and contract.
Before commitment
Align the required evidence, method, validity and applicable lot.
No unsupported promises
Availability and documentation are confirmed during the commercial review.
