From ILAC to Global ACI: What the 2026 Change Means for Your Calibration Certificates

Since 1 January 2026, the two bodies that ran international accreditation recognition, ILAC (laboratories and inspection) and IAF (certification), have operated as a single organisation: Global Accreditation Cooperation Incorporated, known as Global ACI.

What changed

• The ILAC MRA and the IAF MLA have been replaced by a single Global ACI MRA.
• Recognition continues for valid accredited results within the applicable recognised scope. The organisational transition does not extend a certificate's expiry or accreditation coverage.
• The mark transition depends on legal availability in each economy, Secretariat notification and the approvals required by Global ACI MRA-006. There is no single worldwide transition date.

What it means for you

• Existing certificates: the organisational change alone does not invalidate them. Check their normal validity, accredited scope and accreditation status.
• New certificates: use of an ILAC MRA or Global ACI MRA mark depends on the applicable transition rules and accreditation-body authorisation. Do not assume either mark is permitted on every new certificate.
• Supplier approval procedures: if your procedures say “accredited by an ILAC MRA signatory”, update the wording to “a signatory to the Global ACI MRA (formerly ILAC MRA)” to avoid confusion during audits.
