How to conduct customer due diligence (CDD) for sanctions

The FinCEN CDD Rule (31 CFR 1010.230) requires financial institutions to identify and verify beneficial owners, understand customer relationships, and monitor for suspicious activity.

The four pillars of CDD

Pillar	Requirement	Sanctions connection
Customer identification (CIP)	Verify customer identity	Screen against OFAC SDN at onboarding
Beneficial ownership	Identify 25%+ owners	Screen each beneficial owner against SDN
Understand relationship	Profile expected activity	Identify sanctions risk factors
Ongoing monitoring	Monitor transactions	Rescreen against updated SDN list

Step-by-step process

Step 1: Collect customer identity documents.

Step 2: Screen customer name and all beneficial owners against OFAC SDN, EU, UN lists.

Step 3: Assign a risk rating based on customer type, geography, and business model.

Step 4: Set up ongoing monitoring: transaction screening, periodic rescreening, alert investigation.
