Enhanced Due Diligence (EDD): A Compliance Checklist

Enhanced due diligence (EDD) is the deeper level of investigation you apply to high-risk customers, vendors, and counterparties — beyond the standard checks you run on everyone else. Where basic customer due diligence verifies who someone is, EDD asks where their money comes from, who really owns and controls them, and whether dealing with them exposes your business to money laundering, sanctions, fraud, or reputational risk. It is a core expectation under U.S. anti-money-laundering (AML) rules and a practical safeguard for any company — including importers and exporters — that takes on counterparties it does not fully know. This checklist sets out what EDD covers and when to use it.
When Enhanced Due Diligence Is Required
EDD is risk-based: you apply it when a relationship presents elevated risk, not to every customer. Under the federal AML framework — built on the Bank Secrecy Act, the USA PATRIOT Act, and FinCEN’s Customer Due Diligence (CDD) rule — financial institutions must calibrate due diligence to the risk a customer presents. The same logic is good practice for trade-facing businesses screening overseas buyers, suppliers, and intermediaries.
Common EDD triggers include:
A customer or counterparty that is a politically exposed person (PEP) or closely associated with one. Relationships connected to high-risk jurisdictions — countries with weak AML controls, active sanctions exposure, or high corruption risk. Complex or opaque ownership structures, such as shell companies or layered entities that obscure the real owner. Unusual transaction patterns or activity inconsistent with the customer’s stated business. Correspondent banking and other intermediary relationships that carry another institution’s risk. And any counterparty that surfaces a sanctions, watchlist, or adverse-media hit during initial screening.
The Enhanced Due Diligence Checklist
A defensible EDD file is built from the same components every time, documented and dated so an examiner or auditor can follow your reasoning.
| EDD component | What to collect or verify |
|---|---|
| Identity verification | Government IDs, formation documents, registration and licensing for entities |
| Beneficial ownership | Identify and verify each natural person owning 25%+ of a legal entity, plus a control person |
| Source of funds and wealth | Evidence of how the customer earned and accumulated the money involved |
| PEP screening | Check the individual and close associates against PEP databases; assess corruption risk |
| Sanctions and watchlist screening | Screen against OFAC and other restricted-party lists before and during the relationship |
| Adverse media | Search news and public records for fraud, enforcement, or integrity concerns |
| Purpose and nature of the relationship | Document the expected activity, volumes, and rationale for the relationship |
| Risk rating | Assign a documented risk score that drives the depth of review and monitoring |
| Senior management approval | Obtain and record sign-off before onboarding the highest-risk relationships |
| Enhanced ongoing monitoring | Set tighter review cycles and transaction thresholds for the life of the relationship |
The beneficial-ownership element deserves emphasis. FinCEN’s CDD rule requires covered institutions to identify the natural persons who own 25% or more of a legal-entity customer and at least one individual who controls it — precisely because criminals hide behind layered entities. EDD goes a step further, verifying that those owners are who they claim to be and that their funds are legitimate.
Sanctions Screening Is Non-Negotiable
For any business with international counterparties, sanctions screening sits at the center of EDD. U.S. sanctions administered by OFAC apply on a strict-liability basis — a violation can occur regardless of intent — so screening counterparties against the Specially Designated Nationals list and other restricted-party lists is essential, not optional. Build it into onboarding and re-screen periodically, because list designations change. For the mechanics, see how to conduct sanctions risk assessments, denied-party screening in export, and OFAC licenses and exemptions.
Documenting and Maintaining EDD
EDD is not a one-time file. Risk ratings should drive the frequency of review, and information should be refreshed when something changes — a new owner, a change in ownership country, a sanctions designation, or a shift in transaction behavior. Keep the analysis, the supporting documents, and the approvals together, dated and retrievable. If a regulator or counterparty ever asks why you did business with a high-risk party, the EDD file is your answer.
Frequently Asked Questions
What is the difference between CDD and EDD?
Customer due diligence (CDD) is the baseline review applied to all customers — verifying identity and understanding the relationship. Enhanced due diligence (EDD) is the deeper review reserved for higher-risk customers, adding source-of-funds analysis, beneficial-ownership verification, PEP and adverse-media checks, and closer ongoing monitoring.
Who is required to perform enhanced due diligence?
Banks, money services businesses, and other financial institutions covered by the Bank Secrecy Act must apply risk-based EDD. Many non-financial businesses — including importers, exporters, and dealers in high-value goods — adopt the same approach to manage sanctions, fraud, and reputational risk.
What is a politically exposed person (PEP)?
A PEP is someone who holds or has held a prominent public position, along with their close family and associates. PEP status raises corruption and bribery risk, so relationships involving PEPs typically trigger enhanced due diligence and senior-management approval.
How often should EDD be refreshed?
On a risk-based schedule. Higher-risk relationships warrant more frequent review, and EDD should always be refreshed when a triggering event occurs, such as a change in ownership, jurisdiction, or sanctions status.
Enhanced due diligence is where compliance and international trade overlap — the same screening that satisfies AML expectations also protects you from costly sanctions exposure.
