The Bureau of Industry and Security (BIS) has proposed a BIS 50% rule which represents one of the most significant updates to U.S. export control enforcement in recent years.

Under the new rule, any organization that is 50% or more owned (directly or indirectly) by one or more parties on the BIS Entity List may soon be treated as restricted, even if the entity is not named explicitly. This change would dramatically expand the scope of export controls and affect thousands of companies across global supply chains.

By closing the long-standing ownership loophole, the BIS aims to prevent sanctioned parties from using front companies, subsidiaries, shadow entities, and complex corporate structures to evade trade controls. The implications are far-reaching as this rule could introduce new risks overnight, adding layers of complexity to trade compliance.

While the rule is still in draft form, enforcement is not a question of if, but when. For exporters, suppliers, manufacturers, freight forwarders, and export compliance professionals, this means one thing: prepare now. Waiting until the rule goes into effect invites regulatory penalties, export violations, and costly shipment delays.

To stay compliant and competitive, businesses need to implement robust denied party screening tools with deep sanctioned party ownership intelligence that can detect indirect links to Entity List designees.

Key Takeaways

  • The BIS 50% rule, similar to one from the Office of Foreign Assets Control (OFAC), would restrict entities owned 50% or more by one or more parties on the BIS Entity List.
  • It closes a critical loophole that allows restricted parties to operate through unnamed affiliates.
  • Companies must expand their denied party screening to account for ownership structures and indirect control.
  • Delayed action increases the risk of export violations, operational delays, and reputational harm.
  • Now is the time to update systems, training, and due diligence processes to meet evolving export compliance requirements.

What is the BIS 50% Rule? Ownership-Based Export Controls Explained

The proposed BIS 50% rule would expand the definition of a restricted party under U.S. export control laws. Once finalized, it would restrict any entity that is 50% or more owned, directly or indirectly, by one or more parties on the BIS Entity List, even if that entity is not named.

Currently, restrictions apply only to named parties. This has allowed some listed entities to continue procuring sensitive goods through affiliates or subsidiaries. BIS refers to this as the “whack-a-mole” problem.

Key Elements of the Proposed BIS 50 Rule

Modeled after the Department of Treasury’s OFAC 50% rule—which has long treated majority-owned subsidiaries of sanctioned entities as sanctioned, even when not named individually—the BIS version introduces several critical enhancements:

  • Indirect ownership: Apply restrictions to entities with layered, multi-tiered, or shell ownership structures.
  • Ownership aggregation: Combine partial ownership by multiple listed entities to meet the 50% threshold. For example, if two Entity List parties each hold a 25% stake in a company, that company would be treated as restricted.
  • Automatic designation: Entities meeting the ownership criteria would be immediately restricted without needing to be named on the BIS Entity List.

So why is BIS closing the loophole now? The goal is to align trade compliance with sanctions enforcement and prevent diversion, particularly involving entities linked to military modernization efforts in China and Russia.

Additionally, strengthening enforcement by eliminating the need for time-consuming case-by-case designations. A 2023 report by the U.S. House Foreign Affairs Committee called the current BIS list ineffective without ownership tracing. This rule is BIS’s answer, and a signal of more aggressive enforcement to come.

The Export Compliance Impact of the BIS 50% Rule

The proposed BIS 50% rule will fundamentally reshape how companies—especially in global trade, tech, and advanced manufacturing—manage export compliance. Once in force, this rule will demand deeper ownership due diligence, broader screening, and faster response to regulatory changes. Key areas of impact include:

1. Expanded Scope of Denied Party Screening

The rule will require screening for ownership links, not just name matches. Companies must trace corporate connections across parent companies, affiliates, and secondary investors. Export compliance programs without ownership-aware screening systems to detect these indirect relationships increase the chance of missing restricted entities. At the same time, the expanded scope may lead to a surge in false positives—especially for organizations relying on legacy screening tools. Without precise sanctioned ownership data and contextual filters, systems may flag entities with similar names or partial matches, overwhelming compliance teams and slowing down legitimate transactions.

2. Increased Export Violation Risk from Hidden Ownership Links

Without tools for sanctioned ownership mapping, businesses risk unknowingly violating export laws. Opaque structures and offshore holdings make it difficult to identify indirect control, especially across borders. The consequences of missing an ownership link? Costly fines and enforcement actions, blocked shipments or revoked export privileges, and long-term reputational harm.

3. Operational Disruptions for Sensitive Goods

Industries dealing with dual-use technologies, semiconductors, telecom, or aerospace components may face delays as they work to verify ownership compliance. Even one missed link can impact revenue and customer trust. Without fast, accurate restricted party screening capabilities, businesses risk interruptions in export licensing or supply chain approvals, late shipments to critical customers, disruptions in sourcing or procurement.

4. Heavier Due Diligence Burden

The BIS 50% rule raises the bar for what’s considered “reasonable” due diligence. Companies will need to:

  • Map and monitor ownership and control chains.
  • Track mergers, acquisitions, divestments, and investments in real time.
  • Maintain audit-ready records across jurisdictions to prove compliance during inspections.

What was once a quarterly task now becomes an ongoing obligation, especially in high-risk markets.

5. Geopolitical and Retaliatory Risks

Countries affected by expanded U.S. restrictions, targeted countries—especially China and Russia—may respond with countermeasures or blacklist U.S. companies in retaliation. This may complicate cross-border supply chain stability, market access for U.S.-based exporters and strategic partnerships and foreign investments. Global companies must prepare for risk on multiple fronts: regulatory, operational, and geopolitical.

How to Prepare: Your 5-Point BIS 50% Rule Readiness Plan

With the BIS 50% Rule expected to become law soon, businesses must act now—not later. This five-step readiness plan will help strengthen your export compliance program and keep your organization ahead of the curve.

Review Your Denied Party Screening Tools for Ownership Tracing

Many existing denied party screening software only flag exact name matches. That’s not enough under the BIS 50% rule. You’ll need solutions that can:

  • Detect ownership and control links—both direct and indirect.
  • Recognize aggregated ownership stakes across multiple restricted parties.
  • Flag unnamed entities that still fall within the rule’s scope.

Look for solutions that incorporate specialized secondary data sources and can model nested ownership relationships. These capabilities are essential for complying with narrative-based rules, such as BIS 50 and OFAC’s 50% rule.

Deepen your Due Diligence Coverage

The rule requires a broader lens when evaluating customers, vendors, and partners. Traditional entity-level screening is not sufficient. Businesses must map out:

  • Corporate structures and control hierarchies.
  • Shareholders, beneficial owners, and indirect investors.
  • Any affiliated or subsidiary entities with exposure to the BIS Entity List.

In today’s environment of shell companies and offshore entities, due diligence must evolve from static snapshots to continuous monitoring.

Integrate Compliance with ERP, CRM, Procurement, and Other Business Systems

Manual checks slow down business and create inconsistency. By integrating trade compliance into your existing ERP, customer resource management (CRM), sales, procurement, and sourcing workflows, you ensure that denied party list checks happen at every critical point:

  • Onboarding new customers or suppliers.
  • Booking orders.
  • Processing payments.
  • Shipping or exporting goods.
  • Managing recurring business relationships.

Automation reduces delays and ensures scalable compliance, especially when you follow best practices for integrated denied party screening.

Update Export Compliance Policies and Train Internal Teams

Your internal compliance policies should explicitly reflect the broader scope of the BIS 50% rule and clearly define roles and responsibilities for screening, ownership tracing, and escalation. Training should go beyond awareness. Equip the compliance team, as well as the procurement, sales, legal, and logistics teams with practical knowledge on:

  • Identifying red flags in ownership structures.
  • Escalating suspicious parties or affiliations.
  • Using denied party screening tools correctly and consistently.
  • Maintaining documentation standards for audit readiness.
