The Reality of Counterparty Screening: The Limits of Manual Work and the Path to AI
Hello, this is Hamamoto from TIMEWELL. Today I want to talk about "counterparty screening" — the task that consumes the most time for export control practitioners — covering its challenges and solutions.
"Please cross-reference this list against the sanctions lists." — For export control practitioners, this is the most familiar and the most burdensome task. Going through hundreds, sometimes thousands, of counterparty names one by one against multiple sanctions lists. Eyes grow tired, concentration breaks, and yet the pressure of not being allowed to miss anything continues.
This article analyzes the reality and challenges of counterparty screening operations and explains the path to AI-powered solutions.
Chapter 1: The Reality of Screening Operations
What Is a Background Check?
A background check (counterparty due diligence) is the process of confirming whether counterparties or end-users fall under entities of concern under export control regulations. Specifically, it involves cross-referencing against lists such as the following:
- Foreign User List: Companies and organizations of concern regarding involvement in the development of WMDs, published by METI
- U.S. SDN List: Individuals and entities with whom transactions are prohibited, managed by the U.S. Treasury's OFAC
- EU Sanctions List: Sanctions target list jointly managed by EU member states
- UN Security Council Sanctions List: International sanctions target list
Companies doing business globally must check all of these.
The Operational Burden in Numbers
Here are some concrete numbers from surveys we have conducted at client companies.
Reality at a manufacturing company with 500 employees:
| Item | Figure |
|---|---|
| Total counterparties | Approximately 3,000 |
| New counterparties per month | 20–30 |
| Lists to check | 5 or more |
| Average verification time per case | 5–10 minutes |
| Monthly screening man-hours | Approximately 80 hours |
Table 1: Operational reality of counterparty screening
Eighty hours per month means approximately half the time of one dedicated staff member is being spent on screening work alone. Moreover, this figure only covers the "checking work" — adding in detailed investigations of suspicious cases and confirmation of list updates makes it even larger.
Replace siloed classification work with AI.

Chapter 2: Three Limits of Manual Screening
Limit 1: Time and Labor
Traditional screening has been conducted by managing counterparty lists in Excel, downloading various sanctions lists, and comparing names one by one. Even using VLOOKUP or macros, this work requires enormous time.
Moreover, sanctions lists are frequently updated. The U.S. SDN List can be updated multiple times a week, with additions of new sanction targets, modifications to existing information, and removals of sanctions. Every time a list is updated, all counterparties theoretically need to be rechecked. In reality, many companies cannot keep up with these updates.
Limit 2: Accuracy
There are inherent limits to human cross-referencing.
Risk of missed cases: Fatigue and declining attention increase the possibility of missing cases that should have been detected. Maintaining concentration over extended work periods is particularly difficult.
Name variation problem: Even the same person or organization can appear in various forms depending on how the name is spelled. "Muhammad," "Mohammed," "Mohamed" — these may all refer to the same person, but a simple string search cannot detect all variations.
Organization name variation: "ABC Corporation," "ABC Corp.," "ABC Co., Ltd." — these also don't match in simple comparisons.
Limit 3: Knowledge Concentration
Screening work tends to depend on the experience and intuition of seasoned practitioners. When insights like "this name needs attention" or "companies from this country require careful checking" are concentrated in specific individuals, operations stall when those people are absent.
The loss of expertise through personnel transfers and resignations is also a significant problem. Until new staff members learn the work from scratch, there is an ongoing risk of reduced screening accuracy.
Chapter 3: The Transformation Brought by AI
Similar Name Detection Using Natural Language Processing
AI-based screening uses natural language processing technology rather than simple string matching. This makes it possible to detect name variations and similar names.
When Arabic or Asian names are transcribed into Roman letters, multiple variations arise. AI automatically generates these variations and cross-references across all patterns. Cases that "might have been missed" come to the surface.
Judgment That Considers Context
False positives — incorrectly flagging different people with the same name — is a common problem in screening work. AI can reduce false positives by comprehensively considering not just the name but also nationality, address, date of birth, related organizations, and other information.
Continuous List Updates
AI systems automatically obtain and incorporate sanctions list updates. When a list is updated, automatic re-screening of existing counterparties can be performed, and alerts can be triggered for any new matches. The risk of "having missed an update" can be fundamentally eliminated.
Chapter 4: TRAFEED's Counterparty Screening Functions
Multi-LLM Consensus Determination
TRAFEED, which we at TIMEWELL provide, adopts a unique mechanism called "multi-LLM consensus" that leverages multiple LLMs (large language models).
Rather than a single AI making a determination, multiple AIs make independent judgments and the results are synthesized. This reduces the risk of bias and errors stemming from a single AI, producing more reliable results.
Effect of multi-LLM consensus:
| Configuration | Detection accuracy | False positive rate |
|---|---|---|
| Single LLM | 78% | 18% |
| Multi-LLM consensus | 91% | 7% |

Concern-Level Scoring
TRAFEED calculates a "concern level score" for each counterparty. Ranked evaluation from S (highest concern) to C (low concern) lets practitioners see at a glance which cases should be addressed with priority.
Not every case needs to be reviewed at the same depth. By focusing on high-score cases, maximum risk reduction can be achieved within limited time.
Batch Processing and Continuous Monitoring
TRAFEED has the capability to screen large numbers of counterparties in batch. Uploading a CSV file allows cross-referencing of thousands of companies to be completed in a short time.
Additionally, by registering counterparty master data, continuous monitoring can be automated. When sanctions lists are updated, automatic re-screening is performed, and notifications are sent when there are new matches.
Chapter 5: Real-World Implementation Results
Case Study: Manufacturer A
Precision equipment manufacturer A (600 employees) was spending more than 80 hours per month on screening before implementation. Two dedicated staff members shared the work, but even so the situation was far from one where sufficient checking could be said to be happening.
Changes after TRAFEED implementation:
- Screening man-hours: 80 hours/month → 15 hours/month (approximately 80% reduction)
- Newly detected concern cases: 52 cases in the first year after implementation (all addressed through detailed investigation)
- Screening frequency: Quarterly → Weekly (near real-time monitoring)
Case Study: Trading Company B
Major trading company B (approximately 15,000 counterparties) previously required several months for its annual full screening. Unable to keep up with sanctions list updates, the company always carried the risk of "having unknowingly become a counterparty to a sanctions target."
After TRAFEED implementation, screening of 15,000 companies became completable in a few days. Continuous monitoring made it possible to be aware of sanctions list updates in near real time, and the improved framework was evaluated positively in audits.
Chapter 6: Key Points for AI Adoption
Ensuring Data Quality
The accuracy of AI cross-referencing depends on the quality of input data. Misspellings in company names, outdated address information, missing fields — problems in data reduce screening accuracy.
Cleansing data and improving its quality before implementation produces more accurate results.
Establishing Operating Rules
Establish rules in advance for how to handle AI results. Setting clear criteria such as "S-rank always requires detailed investigation" and "C-rank is recorded only" enables efficient operation.
The most important thing is to make explicit the principle that "AI is ultimately a support tool, and the final judgment is made by humans."
Conclusion: Liberation from "Never-Ending Work"
Counterparty screening was "never-ending work" in export control. However, with the use of AI technology, this situation is changing.
Screening at a scale and frequency impossible for humans to match. High-accuracy cross-referencing that handles name variations. Real-time risk awareness through continuous monitoring. These are now reality.
