An electronics distributor based in the Netherlands receives a purchase order from a long-standing customer in South-East Asia. The goods are unclassified commercial items – standard catalogue products, no obvious military application. The compliance team screens the buyer, finds no list hits, and prepares to ship. Then a colleague notices a line in the customer's latest annual report: a newly announced contract to supply components to that country's national defence procurement agency.
Under the BIS / EAR (the Export Administration Regulations administered by the US Bureau of Industry and Security), a military end-use or military end-user prohibition can apply to items that carry no export-control classification number and appear on no restricted list. As of May 2026, the rule targets exports, re-exports, and in-country transfers of items subject to the EAR when the exporter knows, or has reason to know, that those items will be used in the design, development, production, operation, installation, maintenance, repair, overhaul, or refurbishing of military items for certain destinations. The rule is triggered by end-use, not by the technical specification of the goods.
This guide sets out the legal basis for the military end-use controls, the step-by-step compliance procedure, the common points of failure, how the US regime compares with parallel obligations under UK and EU export-control rules, and when a business should involve export-control counsel.
What is the legal basis for military end-use controls under the EAR?
The military end-use and military end-user rules derive from the Export Control Reform Act and are implemented through the EAR by BIS. They sit alongside – but are distinct from – the item-specific controls applied through Export Control Classification Numbers (ECCNs, the alphanumeric codes on the Commerce Control List that determine whether a licence is required for a given item and destination).
The practical effect is that an item classified as EAR99 – meaning it falls outside any positive ECCN and would ordinarily require no licence for most destinations – can still require a licence if the military end-use or military end-user conditions are met. BIS administers the controls and has authority to add foreign military end-users to a published list, which creates a per-se licensing requirement for any item subject to the EAR, regardless of classification.
The prohibition operates on two tracks. The first track is the broad "reason to know" standard: if facts available to the exporter support a conclusion that military end-use is probable, a licence is required before the transaction proceeds, whether or not the destination country is on a designated list. The second track is the listed military end-user standard: certain entities in specified countries are published by BIS, and for those entities the requirement is triggered without a knowledge analysis. Understanding which track applies – and which country groups are in scope – is the starting point for any compliance assessment.
Step 1 – Classify the item and determine whether the EAR applies
The first step in any military end-use analysis is to confirm that the item is subject to the EAR at all. Items subject to the EAR include US-origin goods, software, and technology; foreign-made items that incorporate more than a de minimis proportion of US-controlled content; and foreign-made items that are the direct product of certain US technology or software. Items under the exclusive jurisdiction of the US State Department (the International Traffic in Arms Regulations – ITAR) are outside the EAR.
Once EAR jurisdiction is confirmed, the exporter must classify the item. An item with a positive ECCN already carries specific licensing requirements determined by the control reason and the destination. An EAR99 item carries no positive ECCN. In both cases, however, the military end-use rule layer still applies. Classification does not end the analysis.
In our practice, one of the most frequent errors at this stage is the assumption that an EAR99 classification functions as a clean bill of health for all transactions. It does not. The classification addresses the technical control; the military end-use rule addresses the use. The two questions are independent.
Step 2 – Apply the "reason to know" test to the transaction
The "reason to know" standard requires the exporter to assess all the facts it knows or reasonably should know at the time of the proposed transaction. BIS guidance identifies a series of red flags – indicators that the proposed end-use or end-user may not be as represented. These include unusual payment terms, a buyer that is reluctant to confirm end-use in writing, a shipping route that does not match the stated destination, a buyer with no apparent commercial rationale for the goods, and a stated end-use that is inconsistent with the buyer's known business.
The red-flag analysis is not a checklist that, once completed, shields the exporter from liability. It is a continuing obligation. New information received after an order is placed – a news report, a change in the buyer's corporate structure, a request to re-route the shipment – triggers a fresh assessment. Exporters should document each stage of the analysis: what information was available, what enquiries were made, what conclusions were reached, and on what basis the transaction proceeded or was declined.
Should a transaction proceed where one or more red flags have been identified but not resolved? In our experience the answer is almost invariably no. A single unresolved red flag is sufficient to require either a licence application or a decision not to ship. The EAR's "reason to know" standard is objective: what would a reasonable exporter have concluded on the available facts?
Step 3 – Check the listed military end-user register and the destination country scope
In addition to the knowledge-based prohibition, BIS maintains a list of foreign military end-users to which a licensing requirement applies for all EAR-subject items. An exporter must screen every proposed buyer, freight forwarder, financial institution, and intermediate consignee against this register before each transaction. The register is updated without advance notice.
The country scope of the military end-use and military end-user rules is not universal. The rules currently focus on a defined group of destinations identified in the EAR. For those destinations, the "reason to know" prohibition and the listed end-user prohibition both apply. For other destinations, the analysis reverts to the standard ECCN-based control. Identifying whether the destination is within the rule's country scope is therefore the second screen in the step-by-step procedure.
Exporters working through distributors or intermediaries cannot outsource this obligation. Where goods are sold to a distributor for onward sale, and the exporter has reason to know that the ultimate purchaser may be a military end-user in a covered destination, the licence requirement attaches to the original export. The interposition of a commercial intermediary does not dissolve the exporter's knowledge-based duty.
Step 4 – Determine whether a licence exception applies or a licence application is required
Where the military end-use or military end-user prohibition is triggered, the exporter must determine whether a licence exception is available. The EAR contains a range of licence exceptions, but several of the broadest exceptions are expressly unavailable for military end-use transactions. The practical result is that the pool of available exceptions for military end-use cases is narrower than for standard dual-use transactions.
Where no exception is available, the exporter must apply to BIS for a specific licence before the transaction proceeds. BIS's review of military end-use licence applications involves inter-agency consultation, including with the US Department of Defense and the US Department of State. Processing times vary and can be substantial. Applying for a licence does not authorise the transaction to proceed in the interim.

How does the US military end-use rule compare with UK and EU export-control obligations?
The US military end-use rule is the most explicitly codified of the major regimes, but the UK and EU impose parallel obligations that can apply to the same transaction simultaneously – and the standards diverge in ways that matter in practice.
Under UK export-control rules administered by ECJU (the Export Control Joint Unit), a military end-use catch-all applies to items not listed on the UK strategic-export-control lists. If an exporter knows or suspects that unlisted goods will be used for a military purpose in a destination that is under a UK arms embargo, the exporter must notify ECJU before proceeding. The UK rule is therefore narrower in its destination trigger than the US rule: it is linked to embargo status rather than to a stand-alone country designation. That said, the definition of "military purpose" is broad and does not require that the item be incorporated into a weapon system.
The EU dual-use regulation contains a catch-all that operates on a similar basis: where an exporter knows that items not on the EU control list will be used in connection with military activities in a country subject to an EU arms embargo, a licence is required. EU member states may also impose national-level military end-use controls that go beyond the harmonised regime.
Three practical differences stand out. First, the US rule applies to a broader set of destination countries than the UK and EU catch-alls, which are tied to formal embargo status. Second, the US listed military end-user register creates per-se requirements without a knowledge element; the UK and EU rely more heavily on the exporter's knowledge-based assessment. Third, the extraterritorial reach of the EAR means that a non-US re-exporter of US-origin goods can be subject to the US military end-use rule even where the UK or EU catch-all would not apply.
For a business operating across all three jurisdictions, the practical result is a layered set of obligations. The analysis must be run under each applicable regime, and where the regimes diverge, the stricter prohibition governs the exporter's conduct. We regularly advise businesses that have designed their compliance procedures around one regime and need to expand the scope to account for the others.
What are the common risk flags and mistakes?
The most significant compliance failure we observe is the assumption that item classification is the whole of the analysis. An exporter that confirms a product is EAR99 and stops there has completed less than half the required work. The military end-use layer is a separate, parallel check.
A second common failure is inadequate documentation of the red-flag assessment. Where BIS conducts an export-compliance audit or opens an enforcement investigation, it will examine the contemporaneous record of the exporter's due-diligence process. A conclusion that reached the right answer for the wrong reasons – or that cannot be reconstructed from the records – creates enforcement exposure even where the transaction itself was lawful.
Third, businesses frequently underestimate the re-export dimension. A shipment from the United States to a European distributor may be fully authorised. That distributor's onward sale to a customer in a covered destination triggers the US military end-use analysis afresh. The original US exporter's authorisation does not transfer to the re-exporter. Re-export controls under the EAR are in our experience the least well-understood part of the military end-use regime.
Fourth, the military end-user list is not static. BIS adds and removes entries without a fixed schedule. A screening process that is not integrated with a live update feed will miss new designations. The question to ask is not whether you screened at the start of the relationship, but whether you are screening at each transaction.
A common myth in this space is that the military end-use rules only apply to defence companies or to businesses that knowingly sell into the defence sector. The rules apply to any exporter of any item subject to the EAR, regardless of the exporter's industry. A software firm, a chemical supplier, a logistics company – if their goods are subject to the EAR and the end-use conditions are met, the licence requirement attaches. Sector-neutral compliance coverage is not optional.
If a transaction has already been flagged internally, or if goods have moved before the military end-use analysis was completed, an early review can preserve options that narrow with time. A VSD (voluntary self-disclosure to BIS) is one mechanism available to exporters who identify a potential violation; the decision whether to file requires careful legal assessment of the facts.

Step 5 – Build and maintain a military end-use compliance programme
A transaction-by-transaction analysis is necessary but not sufficient. BIS expects exporters whose product lines or customer base create military end-use exposure to maintain a standing programme element that addresses the rules specifically.
A well-structured programme covers five areas. First, classification: a documented ECCN determination for each product line, reviewed when product specifications change. Second, customer and transaction screening: a defined process for screening buyers, intermediaries, and end-users against the BIS military end-user list and for conducting the red-flag analysis at each transaction. Third, contractual protections: end-use and re-export undertakings in supply agreements, with provisions requiring the buyer to notify the exporter of any change in intended use. Fourth, training: export-control training tailored to the military end-use rules for sales, logistics, and compliance staff who interact with the export process. Fifth, record-keeping: contemporaneous documentation of each classification determination, each red-flag analysis, each licence application, and each licence exception relied upon.
The record-keeping obligation under the EAR runs for a defined period following the transaction. Maintaining adequate records is both a legal obligation and a practical defence in any enforcement proceeding. In our practice, we test the screening logic, map ownership and control in the supply chain, and redesign the programme to address the specific risks of the exporter's product lines and markets.
A micro-scenario illustrates the point. In a recent matter, a precision-instruments manufacturer had operated a standard dual-use export-control programme for several years. A review ahead of entering a new Asian market revealed that several existing distributor relationships involved customers who fell within the BIS military end-use country scope and whose end-use documentation was incomplete. We assessed the classification of each product line, identified the transactions requiring retrospective documentation, advised on the VSD question, and restructured the distributor agreements to include mandatory end-use certification. The manufacturer was able to proceed in the new market with a programme that addressed both the existing exposure and the new risk.
When should you involve export-control counsel?
Counsel should be involved at the outset of any export programme that covers products subject to the EAR and destinations within the military end-use country scope. Waiting until a transaction is flagged or a BIS enquiry arrives increases the difficulty and the cost of the response.
Specific triggers for early counsel involvement include: a buyer or intermediary that cannot provide a credible end-use statement; a request to re-route or re-consign a shipment after the order is placed; an acquisition of or merger with a business that exports EAR-controlled items; a change in a product's specification that may affect its classification or the military end-use exposure; and receipt of any communication from BIS.
We have acted for exporters, distributors, and manufacturers across a range of sectors where the military end-use rules intersected with the business's commercial strategy. The outcome of any individual matter depends on the facts, the applicable rules, and the quality of the compliance record – and we do not promise outcomes. What we can offer is a clear analysis of the position under the EAR, a comparison with parallel UK and EU obligations, and a practical plan for managing the exposure.
