PUBLIC

Understand the process

Review document categories and evidence boundaries before requesting a file.

INQUIRY

Request a document check

Identify the product and request the relevant product-name, grade or batch documents; availability is checked separately.

TESTING / AUDIT

Confirm the review scope

Check the certificate scope and any product-use-market requirements relevant to your trial or audit.

ORDER

Confirm order documents

Match the identified order and batch to the applicable inspection and shipping documents.

Evidence follows its true scope

TDS and SDS follow the product name; specifications follow the commercial grade; COA follows the grade and batch; certificates follow their stated holder, site, product or brand scope; regulatory and import documents follow the product, use and target market.

Traceability is checked for the identified order

Commercial review should connect the ordered specification and lot with the applicable batch and shipping documents.
