Dual-Use Technology and Export Control Complete Guide [2026-June]: China's 40-Entity Measures, U.S. BIS Affiliate Rule (50%), and METI Security Trade Control Guidance v3.0

Hello, this is Ryuta Hamamoto from TIMEWELL.

For most companies, "dual-use" has long been a textbook concept. It shows up in export-control training, sits in a corner of the compliance manual, and almost never surfaces in day-to-day deals. That changed in 2026.

On January 6, China's Ministry of Commerce placed 20 Japanese companies on its Unreliable Entity List and another 20 on a dual-use export-control watchlist (see CISTEC briefing). On February 24, MOFCOM followed up with additional measures that effectively halt dual-use exports from China to those entities (see AMT China Legal Update). Tokyo asked Beijing to withdraw the measures, but the situation remains fluid (see Bloomberg).

Then on April 21, METI amended the operational guidelines for the Three Principles on Defense Equipment Transfer, significantly easing the rules around third-country transfers of jointly developed equipment and the treatment of components embedded in defense systems (see METI 2026-04-21). At the same time, the Wassenaar Arrangement, NSG, AG, and MTCR are progressively expanding their control lists for semiconductor manufacturing equipment, quantum, and AI-related items.

This article walks through the definition of dual-use, the regulatory shifts unfolding in parallel in 2026, the structure of the international regimes, and the operational workflow companies should be running. The final section covers how TRAFEED automates classification work that has become impractical to do by hand.

[Self-Check] Are any of your products classified as dual-use?

Semiconductors, electronic components, optical equipment, precision machinery, telecommunications equipment, rare earths for batteries, and PCs are explicitly named in MOFCOM Announcement No. 1 of 2026 (January 6), which tightened China's dual-use export controls toward Japan[^china0106]. On February 24, 2026, 40 Japanese entities were added to China's export control list and watchlist[^cistec0225].

What Is Dual-Use Technology?

Definition

Dual-use refers to technologies, products, or software that can be used for both civilian and military purposes. Under Japan's Foreign Exchange and Foreign Trade Act and the Export Trade Control Order, dual-use items appear in Items 2 through 15 of Appendix 1, separately from weapons themselves (Item 1).

A related but distinct concept is "military-civilian fusion," which describes a national policy of integrating military and civilian R&D, talent, and capital. China formalized this as a state strategy in 2017. Dual-use is a property of an item; military-civilian fusion is a national framework for exploiting that property. Treating them as the same thing tends to muddle the analysis.

Historical Context

During the Cold War, COCOM (Coordinating Committee for Multilateral Export Controls) governed Western exports to the Eastern bloc. The 1987 Toshiba Machine COCOM violation, in which high-precision machine tools allegedly improved the quieting performance of Soviet submarines, did long-term damage to the U.S.-Japan relationship.

After the Cold War, COCOM was replaced by the Wassenaar Arrangement (WA), which began operating in 1996 as a multilateral framework for transparency in the export of conventional weapons and dual-use items. Japan has been a member from the start (see Wassenaar Arrangement).

From Spin-Off to Spin-On

Historically, technology flowed from military R&D into civilian use (the internet, GPS, microwave ovens). Since the 2010s, the direction has reversed in many domains.

Domain	Status	Examples
Semiconductors	Commercial leads the frontier	TSMC, Samsung advanced logic
AI / ML	Private sector leads research	Large language models, vision models
Drones	Consumer-grade reaches military utility	DJI, Skydio, Autel
Communications	Private-sector-led standards	5G, Starlink

In this "spin-on" era, an unremarkable civilian product can become a core component of a military system once recombined. That, more than anything, is where the difficulty of export control now lives.

What Happened in 2026: China's 40-Entity Measures and the Three Principles Amendment

China's MOFCOM Measures Against 40 Japanese Entities (January 6 and February 24)

On January 6, 2026, China's Ministry of Commerce placed 40 Japanese entities across two lists.

List	Nature	Number of entities
Unreliable Entity List	Trade, investment, and personnel restrictions	20
Dual-use export control watchlist	Heightened review for dual-use exports	20

The listings center on Japanese manufacturers and trading houses with defense-related business, and include companies handling semiconductor manufacturing equipment, specialty chemicals, and precision machinery. The CISTEC briefing (2026-01-06) lays out the entity list and background.

On February 24, MOFCOM issued follow-up measures. According to AMT's China Legal Update (2026-03-02), the new measures effectively halt dual-use exports to the listed entities, with gallium, germanium, and rare earths among the affected critical materials. JETRO also published a corporate-facing summary (2026-02).

Tokyo requested withdrawal, but as of Bloomberg's reporting (2026-02-24), progress has been limited. The market commentary from Sumitomo Mitsui DS Asset Management (2026-01-08) makes the same point I would: this is not a one-off sanction, it is the U.S.-China export-control exchange spilling onto Japan, and it has to be read in that frame.

Supply-Chain Ripples

Companies not on the 40-entity list are not in the clear. Three reasons.

1. Pass-through exposure: suppliers and subcontractors of listed entities may find ongoing transactions difficult to maintain.
2. Critical material sourcing: restricted exports of gallium, germanium, and rare earths from China affect the broader Japanese semiconductor, battery, and motor industries.
3. Heightened scrutiny of third-country routing: China is monitoring transshipment through Hong Kong, Singapore, and Malaysia, so re-routed transactions are themselves under review.

Three Principles on Defense Equipment Transfer: April 21 Amendment

On April 21, 2026, METI and MOFA amended the operational guidelines for the Three Principles on Defense Equipment Transfer (see METI 2026-04-21). For civilian companies handling dual-use items, the practical implications are:

Amendment item	Implication for civilian businesses
Eased third-country transfer of jointly developed defense equipment	More opportunities for civilian suppliers of components
Clearer scope for components and services	Clearer criteria when your product is exported as part of a defense system
Expanded list of recipient countries for finished equipment	More civilian-derived technology flowing beyond the U.S., U.K., and Australia

Read alongside JETRO's report on China's economic-security regime (2026-04), the picture is one of simultaneous easing on the Japanese side and tightening on the Chinese side. Companies handling dual-use items now have to manage different regulatory combinations for each export destination, which is a fundamentally harder problem than it was a year ago.

U.S. BIS Affiliate Rule (50%) and METI Security Trade Control Guidance v3.0

2026 has not only been a year of Chinese action. U.S. export control rules and Japanese operational guidance were updated almost in parallel. For Japanese export control officers, three points need to be on the dashboard.

U.S. BIS Affiliate Rule (50% Rule) — scheduled for November 10, 2026

On September 29, 2025, the U.S. Department of Commerce Bureau of Industry and Security (BIS) issued the final rule commonly referred to as the "Affiliate Rule." Under the rule, any affiliate or subsidiary in which an Entity List–listed company holds, directly or indirectly, 50% or more equity is automatically subject to the same EAR restrictions that apply to the parent listing (see Federal Register 2025-09-30).

On November 10, 2025, the U.S. government issued an interim rule staying the main provisions for one year (see Federal Register 2025-11-12)[^bisaff2511]. The stay is intended as a grace period for companies to build compliance, and the main rule is now expected to take effect on November 10, 2026.

The practical exposure points are roughly:

Scenario	Risk
A 50%+ subsidiary of an Entity List company is a key component supplier to you	Exports and re-exports of products incorporating U.S.-origin technology or parts effectively halt
Your distributor or reseller sells into China via an affiliate of an Entity List company	Potential re-export control violation and U.S. sanctions exposure
Somewhere in a third-country transaction chain there is an affiliate of an Entity List company	Even without a direct contractual relationship, you can still be caught by EAR via the affiliate link

CISTEC has noted that even after the November 2025 stay, "Japanese companies should assume the main rule will take effect one year later and build out a 50% ownership chain check across the entire supply chain in advance."

---

[Effective Nov 10] U.S. Affiliate Rule (50%) Impact Assessment Checklist

The U.S. Affiliate Rule (under which any affiliate 50%+ owned by an Entity List company is automatically in scope), issued on September 30, 2025, was stayed for one year on November 10, 2025, and is now scheduled to take effect on November 10, 2026[^bisaff2511].

• Are any of your key component suppliers 50%+ owned by an Entity List company?
• Could your distributors or resellers indirectly deliver to an Entity List company?
• Are EAR-controlled items used anywhere in your China- or third-country-routed transaction schemes?
• Is your map of parent, subsidiary, and group company relationships up to date?
• Has your internal Compliance Program (CP) been updated to cover the Affiliate Rule?

If any of these are unresolved, a 30-minute TRAFEED consultation will get them organized.

METI "Security Trade Control Guidance — Introductory Edition v3.0" (March, Reiwa 8)

In March 2026 (Reiwa 8), METI released version 3.0 of its introductory Security Trade Control Guidance[^metiguide]. Key changes from version 2 (Reiwa 3):

Update	How v3.0 handles it
Catch-all controls	Reflects the October 9, 2025 catch-all amendment; the end-use flowchart is fully redrawn
Foreign End User List	Notes the recent expansion to 835 entities and illustrates how to screen against listed parties and their affiliates
Deemed exports (resident criteria)	Explains FEFTA's deemed-export rules (technology transfer to residents in specified categories) with worked examples
Export control for SMEs	Introduces a "minimum CP" model for companies running export control with one or two people
Relationship with the Economic Security Promotion Act	Maps the overlap with Specified Critical Materials and Specified Critical Technologies

The defining feature of v3.0 is that it organizes the relationships between security trade control (FEFTA), the Economic Security Promotion Act, deemed-export rules, and catch-all controls in a single document. It is useful both as training material for new export control staff and as a baseline for revising the internal CP.

Catch-All Amendment (October 9, 2025) and the 835-Entity Foreign End User List

The October 9, 2025 catch-all amendment expanded the scope under which a license application is required when the intended use is of concern, regardless of the destination country. In parallel, on September 29, 2025, METI amended the Foreign End User List, expanding the number of listed entities to 835[^userlist].

The operational implication is simple: more cross-referencing of listed parties, affiliates, and group companies. According to METI's December 2025 "Analysis of FEFTA Violations (FY2024)," 52% of violations stemmed from classification errors and 36% from deficiencies in management systems[^meti2024]. From the field, the companies whose process leans heavily on manual work are exactly the ones who accumulate violation risk with every regulatory update.

International Export Control Regimes and Japan's Position

The Four Major Regimes

Dual-use controls are not set unilaterally by each country. They are agreed at the international level and then implemented through national law.

Regime	Scope	Members (2026)
Wassenaar Arrangement (WA)	Conventional weapons and dual-use items	42
NSG (Nuclear Suppliers Group)	Nuclear-related items and technology	48
AG (Australia Group)	Chemical and biological weapons-related	43
MTCR (Missile Technology Control Regime)	Missile-related technology	35

Japan is a member of all four. Items agreed at these regimes are reflected in Appendix 1 (List Controls) of Japan's Export Trade Control Order.

Relationship with Catch-All Controls

Goods or technology that fall outside list controls can still require an export license if there is objective awareness of military diversion, or if end-user or end-use criteria apply. This is "catch-all" control.

Category	Basis	Trigger
List controls	Appendix 1 (Items 1–15)	Specifications and performance thresholds
Catch-all (end-use)	METI notification	End use linked to weapons of mass destruction or conventional weapons
Catch-all (end-user)	Foreign End User List	Buyer is on the list of concern
Catch-all (inform)	Direct notice from METI	Case-specific government notification

Recent Regime Updates

At its end-2025 plenary, WA added certain EUV lithography accessory equipment, cryogenic systems for quantum computing, and specific accelerators used for AI inference. These additions are now being implemented in national law across member countries.

NSG is discussing high-performance carbon fiber for uranium enrichment, AG is examining synthetic biology equipment, and MTCR is reviewing solid propellants for small-satellite launch vehicles. The METI Security Trade Control page (METI 安保貸管) tracks the implementation timeline.

Operational Workflow for Handling Dual-Use Items

A practical five-step workflow for running export deals.

Step 1: Initial Screening Using HS Codes

Start from the HS code (tariff classification) to identify which item of Appendix 1 your product might fall under. HS codes are designed for tariffs and do not map one-to-one with export-control categories, but they are a useful entry point.

For full classification, cross-reference the item-by-item matrix tables published by METI and CISTEC against your product's specifications. The judgment criteria are mostly numerical (precision, temperature range, resolution, and so on).

Step 2: List Control Classification

Prepare a parameter sheet and check it against the criteria for each item of Appendix 1.

Item	Scope	Representative criteria
5	Advanced materials	Tensile strength, fiber alignment, purity
6	Materials processing	Positioning accuracy, axes, temperature range
7	Electronics	Operating temperature, radiation hardness, computing speed
8	Computers	Compute performance (TOPS/FLOPS)
9	Telecommunications	Frequency range, encryption strength
10	Sensors	Sensitivity, detection wavelength, resolution

If the item falls within a list control, an export license from METI is required. Even when the conclusion is "non-applicable," the rationale is documented in a classification record.

Step 3: End-User Screening

Cross-reference the buyer, end user, and final end user against METI's Foreign End User List. Listed parties are treated as end users of concern, requiring an individual export license for dual-use items.

Given the China 40-company measures, there is now an additional check: whether your business partner is itself on a Chinese-side restriction list.

Step 4: End-Use Review

Verify the following about the end user and intended use:

• The use is not connected to development, production, use, or stockpiling of weapons of mass destruction (nuclear, chemical, biological, missile).
• It is not connected to conventional weapons.
• The stated use is plausible (no large orders for what should be a low-volume application, no refusal of technical support, no insistence on cash terms).

The end-use criterion triggers when there is "objective awareness" or when METI has issued an inform notice. When in doubt, advance consultation with METI or CISTEC is the realistic move.

Step 5: Issue the Non-Applicable Certificate and Retain Records

When a product is classified as non-applicable, you typically issue a non-applicable certificate (parameter sheet) at the buyer's request and keep the rationale on file. The legal retention period is seven years, but the supply-chain traceability case for keeping records longer is strong.

For details, see Non-Applicable Certificate Writing Guide. For broader context on Japan's discussions around an espionage-prevention law and security clearance, see Spy Prevention Law and Business.

Automating Classification with TRAFEED

Running the workflow above manually has become impractical for most teams, and I would say the practical tipping point arrived in 2026. Three reasons.

1. List-control items keep growing with each international regime update.
2. China, the U.S., and the EU are all tightening controls in different directions, so each export destination requires a different cross-reference.
3. Reference lists keep multiplying: Foreign End User List, China's 40-entity measures, OFAC SDN, EU and U.K. sanctions.

TRAFEED (formerly ZEROCK ExCHECK) is built as the world's first export-control AI agent, designed to automate exactly this workflow.

Capability	Description
HS-code-driven classification support	Enter product specifications and TRAFEED estimates the applicable Appendix 1 item
Multilingual screening	Cross-references Foreign End User List, OFAC SDN, China's 40-entity list, EU and U.K. sanctions across languages
Automatic regulatory updates	Automatically ingests WA, NSG, AG, MTCR updates and national sanctions list changes
Auto-generated classification records	Outputs in parameter-sheet format, ready for internal review
Audit log	Retains every classification decision, aligned with the seven-year retention requirement

The design intent is straightforward: a METI-aligned AI that cuts classification effort by roughly 90 percent. The companies that benefit most are mid-sized manufacturers running export control with one or two people, where doing the work manually is no longer feasible.

If your reaction to all of this is "we only ship civilian goods, this doesn't apply to us," that is the signal to run a classification check anyway. In the 2026 environment, the bigger risk is not knowing that your product is in fact a dual-use item.

2026: The Year Regulations Move in Parallel — Making Dual-Use Management a Rapid-Response Capability

China's 40-entity export restriction list against Japan, the U.S. BIS Affiliate Rule (50% Rule), METI Security Trade Control Guidance v3.0 (March, Reiwa 8)[^metiguide], the October 9, 2025 catch-all amendment, and the Foreign End User List of 835 entities[^userlist]. 2026 is the year in which the regulatory environment moved on multiple fronts at once, and the workload for export control officers handling dual-use technology has clearly increased. METI's December 2025 "Analysis of FY2024 FEFTA Violations" found that 52% of violations stemmed from classification errors and 36% from gaps in the management system[^meti2024].

TIMEWELL's TRAFEED (formerly ZEROCK ExCHECK) is built as the world's first export-control AI agent. It automates dual-use classification, catch-all controls, and cross-referencing against counterparty lists.

Issues TRAFEED solves

Issue	How TRAFEED solves it
Dual-use classification is locked in a few people's heads and falls apart when they leave	Classification rationale is stored as structured data, making handover automatic
Cross-checking against the 835-entity Foreign End User List and China's 40-entity measures takes too long	Upload a counterparty list and get a bulk cross-reference in five seconds
The 50% ownership chain check for November's Affiliate Rule is still manual	Parent, subsidiary, and group company structures are expanded automatically
Item-by-item comparison tables and CP updates lag every regulatory amendment	Legal updates are captured automatically and reflected in the classification logic

[Who this is for]

• Manufacturers handling dual-use items where one or two people own the export control function
• Companies whose suppliers or customers may fall under China's 40-entity list against Japan
• Trading houses and SI vendors that need to assess Affiliate Rule (50% Rule) exposure ahead of November 10
• Organizations rebuilding their internal CP in line with METI Security Trade Control Guidance v3.0

Summary

• In 2026, dual-use (civil-military) shifted from a textbook concept to a live regulatory risk.
• China's 40-entity measures (January 6 and February 24), Japan's amendment to the Three Principles on Defense Equipment Transfer (April 21), the U.S. Affiliate Rule taking effect on November 10, and METI Security Trade Control Guidance v3.0 (March, Reiwa 8) are all moving in parallel.
• The October 9, 2025 catch-all amendment and the expansion of the Foreign End User List to 835 entities have structurally increased the cross-referencing workload.
• The practical workflow is HS-code-driven classification, end-user screening against the Foreign End User List, end-use review, and retention of non-applicable certificates.
• With the volume of reference lists and regulatory updates still growing, AI-driven automation is now a realistic option rather than a luxury.
• TRAFEED, designed as a METI-aligned export-control AI agent, automates classification and screening end-to-end.
