Guide contents

Define product and material scope

PFAS questions should identify the supplied part, formulation, material or product family rather than relying on a broad company-level statement.

Ask for evidence context

Supplier responses may need declarations, test reports, specifications or upstream information depending on the use case and jurisdiction.

Track unknowns explicitly

Unknown composition, incomplete upstream data and supplier non-response should remain visible as gaps rather than being converted into false certainty.

Version responses over time

Regulatory expectations and supplier formulations change, so the system should preserve prior responses and the current reviewed state.
