Supplier evaluation should cover more than price and a single COA image. A structured procurement review looks at business transparency, batch traceability, analytical evidence, communication and order documentation.

Business transparency

• Is the seller identity clearly stated?
• Are contact and policy pages accessible?
• Are shipping, returns and research-use restrictions visible before checkout?

Product record quality

• Material name and declared content are clear.
• Format and intended research use are stated.
• Availability is separated from analytical claims.

Documentation quality

• Batch or lot identifiers are present where applicable.
• Supplier documents and independent testing are labelled separately.
• Methods and actual test scope are stated.
• Missing parameters are not implied from unrelated results.

Traceability

• Reports can be linked to the physical inventory lot.
• Changes between batches are documented.
• Historical reports are labelled as historical or representative.

Communication

• Batch-specific documentation can be requested.
• Questions about report source and lot linkage receive clear answers.
• Corrections are documented when public information changes.
