Decoded for Operations

How aggregated ownership screening protects high-security facilities from inadvertent violations, and how to implement it without slowing operations.

Rule Postponed

Update

November 10, 2025

BIS Affiliates Rule Postponed: The 50% rule enforcement is paused for one year after the Trump–Xi summit. The pause is active now, but the rule is expected to snap back on November 10, 2026.

By default, SecurePoint USA calculates OFAC 50% ownership in shadow mode: the result is recorded but does not change the screening decision. BIS 50% affiliate rule enforcement is paused until November 2026. Until then, ownership screening continues with escalation workflows.

Affiliates Rule Paused

BIS stayed the Affiliates Rule for one year starting November 10, 2025 after the U.S.–China trade summit.

Return Expected 2026

Expect the Affiliates Rule to resume on November 10, 2026; use the pause to harden ownership workflows.

Ownership Screening Still Critical

Even during the pause, teams must resolve Red Flag 29 scenarios and keep Entity/MEU ownership look-through.

Previous Alert

Original BIS 50% Rule (Effective Sept 30)

BIS aligned with OFAC’s long-standing 50% rule, applying Entity List and MEU List restrictions to majority-owned foreign affiliates. A temporary general license (TGL) through November 28, 2025 provides time to map ownership, shore up controls, and seek required licenses before the rule restarts.

50% Aggregate Ownership

Any entity 50%+ owned (directly or indirectly) by Entity List or MEU List parties inherits their restrictions.

Temporary General License

A 60-day TGL (through Nov 28, 2025) lets exporters assess affiliates, gather attestations, and file licenses.

Red Flag 29

Exporters now have explicit duty to resolve ownership uncertainty; unresolved cases need a BIS license.

What is the 50% Rule?

OFAC's 50 Percent Rule treats any entity owned 50% or more by one or more Specially Designated Nationals as blocked, even if the entity isn't listed. BIS extends the same logic to Entity List and MEU List ownership (currently postponed until November 2026).

"If Person A (blocked) owns 30% and Person B (blocked) owns 25%, the entity is 55% blocked and must be treated as sanctioned."

What Screening Must Capture

Three non-negotiable requirements for compliance

Aggregate Ownership Detection

Spot when multiple listed parties collectively cross 50%, even if no single owner holds a majority.

Deep Ownership Chains

Trace two-hop subsidiaries and shell structures that inherit Entity List or MEU status.

Append-Only Audit Trail

Document every ownership lookup, escalation, and license decision for a BIS review.

Intelligent Screening Architecture

Built for high-security environments where speed and accuracy must coexist.

Ownership Look-Through

Where ownership records exist, calculate whether blocked persons own 50% or more of a vendor. Results run in shadow mode by default.

Intelligent Adjudication

Decision-makers see applied thresholds, diagrams, and evidence without leaving the queue.

List coverage

Screen against the BIS Entity List. Denied Persons List screening is available when enabled. There is no buyer-facing Entity List versus MEU toggle.

Scheduled re-screening

Workforce and vendor re-screens run on a daily schedule against the lists you run. Ownership-change monitoring is not a live scheduled control.

Operational Playbook

Four steps to put the 50% Rule into practice

01

Entity Capture

Implement at check-in

Capture visitor and company legal names at check-in or vendor onboarding.

02

Ownership Verification

Policy-based triggers

Request attestations or registry docs for high-risk affiliates; map at least two ownership layers.

03

Compliance Escalation

Automated workflow

Escalate unresolved Red Flag 29 cases for license evaluation or hold decisions.

04

Audit Documentation

One-click export

Generate evidence packs from visit, screening, and decision records.

Why This Matters for Your Facility

Regulatory violations carry severe penalties: civil penalties under IEEPA (50 U.S.C. 1705) are inflation-adjusted and can also be twice the transaction amount. Criminal exposure and loss of facility access can follow.

Reputational damage compounds: failed audits can trigger contract reviews, clearance investigations, and stakeholder scrutiny.

Operational efficiency matters: SecurePoint USA automates complex ownership analysis so throughput stays high even under BIS scrutiny.

Screen visitors, review matches, and keep the record.

Readiness checklist while the BIS Affiliates Rule is paused

A short checklist to keep visitor and vendor screening evidence in order while the Affiliates Rule stay remains in effect.

  • Extend screening beyond CSL hits to include ownership graphs and parent lookups.
  • Increase re-screen cadence; even 1% changes can push a subsidiary past the 50% threshold.
  • Update SOPs and LMS modules to reflect the paused-but-returning Affiliates Rule.
  • Refresh contract clauses with licensing/termination language ahead of 2026.
  • Document escalation paths for Entity/MEU overlaps and Red Flag 29 resolutions.

Key Takeaways

  • The OFAC 50% Rule treats entities 50%+ owned by Specially Designated Nationals as blocked, even if not directly listed.
  • BIS Affiliates Rule remains stayed through November 9, 2026, with reimposition scheduled for November 10, 2026. Treat that date as scheduled, not guaranteed.
  • Aggregate ownership detection must identify when multiple listed parties collectively cross 50%, even if no single owner holds a majority.
  • Append-only audit trails are essential for documenting ownership lookups, escalations, and license decisions to survive BIS audits.
  • SecurePoint USA can traverse ownership chains where ownership records exist. OFAC 50% results run in shadow mode by default: they are stored in screening metadata and do not change the access decision unless an organization turns enforcement on. BIS affiliate hits are held for review.
