The 50% Rule Is Changing How You Screen: What Exporters Need to Know Now

Imagine winning an international bid, building the entire solution, then discovering at the eleventh hour that your buyer is 50% owned by a blocked party. The deal dies, and tens of millions vanish. We have seen it happen. The 50% rule is not a footnote in export compliance, it is a project killer if you get it wrong.

What Is the 50% Rule and Why It Matters

As exporters, we know the government publishes who we cannot do business with on lists like the OFAC SDN List and other restricted party lists. The 50% rule goes further. If a sanctioned individual or entity owns 50% or more of another company, that downstream company is also restricted. Ownership can be direct or aggregated through multiple sanctioned owners, which multiplies your screening risk across hidden networks.

• OFAC 50% Rule: Active for years, and enforcement is ramping up for exporters.
• BIS 50% Rule: Announced, with implementation delayed for a year, which gives you time to prepare.

The takeaway is simple. It is not enough to screen names. You must understand ownership, control, and networks behind every counterparty.

The Real Challenge: Hidden Ownership and Limited Public Data

Federal lists do not publish all the beneficial owners of every restricted party. You cannot manually trace global ownership chains across shell companies and intermediaries, especially under tight deal timelines. Without the right data and tools, you will miss links that trigger the 50% rule and expose your company to penalties, shipment holds, reputational damage, or last-minute cancellations.

A Technology-First Approach to Sanctions Screening

The only practical way to operationalize the 50% rule is through technology that maps ownership networks and syncs with your screening program. Third-party data and analytics providers can surface relationships that are not obvious in public filings.

We partner with leading network-mapping providers like Sayari, Altana and Kharon to enrich restricted party screening with beneficial ownership intelligence. When these datasets are connected to our compliance software, your team can:

• Screen customers, vendors, and end users against SDN and other restricted lists with ownership context
• See upstream and lateral relationships that implicate the 50% rule
• Automate alerts, reviews, and documentation for audits
• Reduce false positives and speed up adjudication

Actionable Steps You Can Take Now

• Inventory your counterparties: Customers, distributors, resellers, freight forwarders, and end users.
• Implement a risk-based screening cadence: Pre-engagement, pre-shipment, and ongoing rescreening for long projects.
• Add ownership intelligence: Use third-party mapping to identify aggregated 50% control and indirect ownership.
• Define escalation rules: Set thresholds for review, evidence requirements, and decision authorities.
• Keep records: Preserve screening results, ownership findings, and adjudication notes for at least five years.
• Prepare for the BIS 50 timeline: Use the current delay to pilot, test, and train so you are ready before enforcement tightens.

The Cost of Waiting Is Real

Years ago we worked with a company that built a large international project before discovering a prohibited 50% ownership link. The issue was found late, the project was canceled, and both the company and its customers absorbed losses in the tens of millions. Early screening with ownership analysis would have prevented it.
