ADNOC IDD: what it is and how to pass it

Many ADNOC supplier registrations don't stall on technical questions. They stall on the Integrity Due Diligence. Here is what it looks at, and how to prepare it so it goes through without weeks of back-and-forth.

What the IDD is

Integrity Due Diligence (IDD) is ADNOC's check of who you are and how you do business, before you become a supplier. It is part of the supplier registration, alongside your company profile, licence and financials.

What it looks at

  • Ownership: your shareholders and the people who ultimately own or control the company.
  • Management: directors, managers and authorized signatories.
  • Relationships: connections with government officials or ADNOC employees that must be declared.
  • Compliance: sanctions exposure, past investigations or disputes, and your anti-bribery and compliance policies.
  • Agents and partners: anyone who acts on your behalf with ADNOC.

Why IDDs get stuck

  • Answers that don't match the documents. The shareholder named in the questionnaire must match the trade licence and the memorandum of association, spelling included.
  • Incomplete ownership chains. If a shareholder is another company, reviewers expect to see who stands behind it.
  • Undeclared relationships. A connection declared upfront is usually manageable. One discovered later is a serious problem.
  • Missing policies. A short, real code of conduct and anti-bribery policy is better than none.
  • Slow answers. Every unanswered clarification adds days.

How to prepare it properly

  1. Line up your corporate documents first: licence, memorandum, shareholder register and signatory authorizations. Fix any inconsistency before you answer a single question.
  2. Map the full ownership down to the individuals who own or control the company.
  3. Decide what must be declared and declare it clearly. Transparency is what reviewers look for.
  4. Have your compliance documents ready: code of conduct and anti-bribery policy, signed and dated.
  5. Name one person responsible for answering ADNOC's questions quickly.

We prepare the IDD with you, check every answer against your documents before submission, and handle the follow-up. The decision is always ADNOC's; our job is a file that is consistent, complete and honest the first time.

Questions we are asked

What does IDD mean at ADNOC?

Integrity Due Diligence: ADNOC's review of a supplier's ownership, management, relationships and compliance before registration.

Why is my ADNOC registration stuck at IDD?

Most often because answers don't match corporate documents, the ownership chain is incomplete, relationships were not declared, or clarification requests were not answered quickly.

Do I need a compliance policy for the IDD?

Having a real code of conduct and anti-bribery policy helps. Reviewers look for evidence that the company manages integrity risks.
