All material suppliers and sub-suppliers assessed according to this standard within the Due Diligence System are included. Suppliers and sub-suppliers aren't required to follow this standard, but it's the organization's responsibility to ensure conformity.

The Due Diligence System should be reviewed and, if needed, updated at least once a year and before the annual certification body surveillance, or when changes affect the relevance, effectiveness, or adequacy of the Due Diligence System. Verification methods may include stakeholder consultation, field verification, and document checks, conducted through internal audits.
