The short version: nothing changes for your accreditation, and nothing is required from you right now. When the new combined mark becomes available, expected in March 2027, NAC will send you instructions. Until then, keep using your current marks as you do today.
Your checklist
Keep your current mark. The existing IAF MLA and ILAC MRA marks stay valid and are treated as equivalent to the new one.
Do not start using the new mark early. Wait for NAC’s written notice. Using it before it is available in your economy may count as a misleading claim.
Review where your marks appear. Reports, certificates, websites, letterheads and quotations. This makes the switch easier later.
Check your claims. A statement about your accreditation must name only the activities and standards in your scope.

What is Global ACI?
Until the end of 2025, two organizations ran the international arrangements that let accreditation results be accepted across borders: IAF for certification and inspection, ILAC for laboratories. On 1 January 2026 their work was combined under one organization, Global Accreditation Cooperation Incorporated (Global ACI).
Global ACI has also published a new combined mark and a rulebook for it, MRA-006. It covers who may use the mark, within what limits, and how accredited status may be described.
What the new mark tells your customers
NAC is a signatory to the multilateral recognition arrangement.
Your organization is accredited to an internationally recognized standard.
The mark applies only to your accredited scope. It is not a general statement about the whole organization.
Planned sequence
Now to March 2027: current marks in use, no changes to requirements.
From March 2027: the combined mark becomes available. NAC will give you the procedure and a transition date.
After that: legacy marks are phased out over a period set by Global ACI, which may be extended where regulators or markets need it.
Questions we expect
Will my accreditation be affected? No. The transition changes the mark and the rules for using it, not your scope or status.
Can my customers still rely on our current certificates and reports? Yes. Current marks are recognized during the whole transition.
Who decides when I switch? NAC will tell you. You do not need to act on your own.
