What verification tells you.

Participation status and sample findings answer separate questions.

Membership

Active means a vendor meets current participation requirements and accepts independent scrutiny. It does not mean every product passed or the vendor has already been independently tested.

Testing history

When no independent report is available, the profile says No test results published. Completed events awaiting public disclosure are identified as pending publication. Actual events identify products, lots, dates, laboratories, methods, identity and purity findings, and public reports.

Later manufacturer programs

Manufacturer Greenlisting is a future program, not a current enrollment prerequisite. Current membership and actual sample findings remain separate.

An active member may not have published test results.
