A freight forwarder arranges a container shipment through three transit ports. The ultimate consignee looks clean. The vessel itself, however, has recently changed flag and ownership. One intermediate broker sits on a watchlist. The export licence was filed for the origin country – but the re-export through a second jurisdiction was never assessed. Under the Export Administration Regulations (the EAR – the US Bureau of Industry and Security's controls on commercial and dual-use goods), that oversight can constitute a violation regardless of where the forwarder is incorporated.
Managing maritime and shipping sanctions under BIS / EAR requires exporters and intermediaries to classify every item under the Commerce Control List, confirm whether a licence or licence exception applies, screen every party in the transaction chain – vessel, owner, operator, broker, consignee – and trace the cargo through every re-export leg. As of January 2026, BIS imposes extraterritorial controls through the de minimis and foreign direct product rules, meaning a non-US carrier moving US-origin or US-technology goods can trigger EAR jurisdiction. Failure to address this correctly exposes the exporter, the freight forwarder, and potentially the vessel operator to denial orders, civil penalties, and criminal referral.
This guide walks through the procedure step by step, compares the BIS / EAR position with the OFAC and OFSI approaches where they diverge, and flags the points at which early legal review changes the outcome.
Step 1 – Establish whether the EAR applies to the shipment
The EAR governs all items "subject to the EAR" – broadly, goods, software, and technology that are either of US origin, contain more than a de minimis proportion of controlled US content, or are the direct product of certain US technology or software. For a maritime cargo, the jurisdictional question must be answered before anything else.
Two doctrines extend EAR jurisdiction beyond US-origin goods. The de minimis rule (a threshold test based on the percentage of controlled US content in a foreign-made item) means that even a non-US product can be subject to the EAR if US-controlled components or software exceed the applicable percentage. The foreign direct product rule goes further: it can subject foreign-made items to the EAR when they are produced using certain US technology, equipment, or software. In our cross-border practice, these two doctrines are the most common sources of surprise jurisdiction – particularly for European and Asian manufacturers who believe they are dealing with purely local products.
For maritime shipments, the practical consequence is significant. A vessel carrying foreign-manufactured goods may be carrying EAR-subject cargo without the shipper having recognised it. The determination must be made cargo-by-cargo, not vessel-by-vessel. The analysis begins before the booking is confirmed.
Step 2 – Classify the cargo and identify licence requirements
Every item subject to the EAR has a classification. An ECCN (Export Control Classification Number, the BIS code on the Commerce Control List that determines the controls applicable to an item) is either assigned by BIS or self-classified by the exporter. Items without an ECCN are classified EAR99 – the lowest-control designation – but EAR99 items can still require a licence to certain destinations, end-users, or for certain end-uses.
Classification determines which licence requirements apply. Some ECCNs carry licence requirements to all destinations except certain close allies. Others are destination-neutral but trigger review when the end-use is military, nuclear, chemical, biological, or missile-related. For maritime cargo, the classification exercise has three layers: the goods themselves, any software embedded in them, and any technical data transferred as part of the transaction (such as installation manuals or calibration data transmitted electronically).
Once the ECCN is established, the exporter should check whether a licence exception (a standing authorisation to export, re-export, or transfer an item without a separate licence application, provided specific conditions are met) is available. Common maritime-relevant exceptions cover low-value shipments, technology already in the public domain, and temporary exports for repair. Exceptions are not automatic; they carry eligibility conditions that must be verified for every shipment. Documenting that assessment – and retaining that documentation – is part of the compliance obligation.
Step 3 – Screen every party in the maritime transaction chain
Licensing and classification address the goods. Party screening addresses who handles, owns, or benefits from them. Under the EAR, no export, re-export, or transfer may proceed where a party to the transaction is on BIS's Entity List, the Denied Persons List, or the Unverified List; and OFAC's SDN List (Specially Designated Nationals and blocked persons list – OFAC's primary sanctions list) applies in parallel.
In maritime transactions, the party chain is longer than in a standard commercial sale. It includes, at minimum: the shipper, the freight forwarder, the customs broker, the vessel owner, the vessel operator, the vessel manager, the charterer, the flag-state registry, the port agent, the consignee, and any known beneficial consignee behind the named party. We regularly advise clients that a clean ECCN and a valid exception mean nothing if one of those parties is subject to a denial order or an OFAC block.
Vessel-level screening adds a layer that general trade compliance programmes rarely address well. Vessels can change name, flag, and registered owner rapidly. A vessel that screened clean at booking may have changed ownership by the time it loads. Checking the IMO number (a permanent identifier that does not change with the vessel's name or flag) against current sanctions lists at each stage – booking, loading, sailing – is the standard that BIS and OFAC have signalled they expect from sophisticated shippers.
What does your screening programme do when a vessel changes its AIS transponder status mid-voyage? That question is not rhetorical. Transponder manipulation – going dark – is a recognised red flag under US, UK, and EU maritime sanctions guidance. The detection of it should trigger a hold and a compliance review, not a commercial decision.
Step 4 – Assess re-export and in-transit obligations
The EAR's re-export controls are among the most operationally demanding aspects of maritime trade compliance. A party outside the United States who re-exports an EAR-subject item must assess whether that re-export requires a licence just as the original US exporter would have done. Crucially, the re-export assessment must be made by the re-exporter – not merely relied upon from the original US export licence.
For containerised maritime cargo moving through multiple ports, each transshipment point can constitute a re-export if the goods are moving from one foreign country to another. The container may physically remain sealed. The change in destination nonetheless triggers a fresh EAR analysis. In practice, this means that a freight forwarder routing cargo through Singapore, the UAE, or another regional hub must assess EAR applicability for the leg from the hub to the ultimate destination – not just from the United States to the hub.
The in-transit rule is distinct from re-export but equally relevant for vessels passing through ports in controlled or sensitive jurisdictions. Cargo that enters a jurisdiction only in transit – never clearing customs – can still trigger local sanctions and export-control obligations of the transit jurisdiction, in addition to any continuing EAR obligations. Cross-regime awareness here is essential: the EAR, OFAC's sanctions programmes, the EU dual-use regime, and the OFSI export licensing rules can all bite at different points of the same voyage.
The position above covers the standard case. Your facts – the vessel flag, the intermediate ports, the end-user's jurisdiction, the precise goods classification – will change the analysis. For an early-stage assessment of your maritime transaction, contact Calder & Vance at info@caldervance.com.
Step 5 – Identify and manage maritime-specific red flags
Red flags are the point at which BIS and OFAC most commonly find fault with compliance programmes. Both regulators have articulated lists of indicators that should cause a shipper, forwarder, or financial intermediary to pause and investigate before proceeding.
In maritime operations, the most significant red flags include the following:
- Vessel name, flag, or ownership changes shortly before or after booking.
- A vessel's AIS transponder is disabled, manipulated, or shows irregular position data.
- The ultimate destination is inconsistent with the declared end-use or the consignee's known business.
- Payment is routed through a jurisdiction that has no obvious connection to the transaction.
- The consignee requests unusual shipping routes or mid-voyage destination changes.
- Cargo is described in generic terms inconsistent with the goods actually shipped.
- The freight forwarder or intermediate broker is newly incorporated or unfamiliar to the exporter.
Each of these indicators, taken alone, does not establish a violation. Taken together – or in combination with a destination that is sensitive under the EAR – they create what BIS calls "reason to know" that the item may be destined for a prohibited end-use or end-user. Acting on a red flag requires investigation, documentation, and often a hold on the shipment. Proceeding despite a known red flag can convert an inadvertent violation into a wilful one, which carries substantially higher penalties under the applicable regime.
We have advised clients in the shipping, commodities, and logistics sectors where a single uninvestigated red flag at the freight forwarder level became the basis for a BIS compliance review. The cost of the review, the remediation programme, and the reputational disruption far exceeded what a pre-shipment legal assessment would have cost.
How does BIS / EAR differ from OFAC and OFSI in the maritime context?
The BIS / EAR and OFAC regimes address different legal questions, but they overlap in the maritime space in ways that create material risk for exporters who treat them as alternatives rather than as parallel obligations.
OFAC administers US economic sanctions – asset freezes, prohibitions on dealing with listed persons and blocked entities, and country-programme restrictions. The BIS / EAR administers export controls – item-specific and destination-specific controls on the movement of goods, software, and technology. A shipment may need both an OFAC analysis (are any parties blocked? does the destination fall under a country programme?) and an EAR analysis (does the item require a licence?). The answer to one does not relieve the obligation to answer the other.
The key operational divergence in the maritime context is the standard of liability. OFAC operates a strict liability regime for civil violations: an exporter who unknowingly transacts with a blocked person can face civil penalties even without knowledge or intent. BIS applies a knowledge-and-reason-to-know standard for many violations, but wilful violations carry criminal liability. OFSI in the United Kingdom, since the amendments to SAMLA that introduced a civil monetary penalty regime, operates a similarly strict approach for civil penalties. The EU regime is applied through member-state authorities and the standard varies, though intent is typically relevant to criminal liability.
Ownership and control is another divergence point. OFAC's 50 percent rule (the rule that an entity owned 50 percent or more in aggregate by one or more blocked persons is itself treated as blocked) is mechanical and does not incorporate a control test. OFSI and the EU apply an ownership and control test (a broader test that treats a non-listed entity as caught where a listed person holds it, owns it, or controls it) – meaning a vessel or shipping company with minority ownership by a listed person could still be caught under UK or EU rules if control is established, even if OFAC's 50 percent threshold is not met.
For a business operating transatlantic or cross-border shipping routes, the stricter prohibition governs at each point. A cargo that is permitted under the EAR may be prohibited under an OFAC country programme. A vessel cleared under OFAC's 50 percent rule may be caught under OFSI's control test. Running the analysis on only one regime is not a defence.
If a transaction has already been flagged, or a filing has been refused, an early review can preserve options that narrow with time. Contact Calder & Vance at info@caldervance.com to discuss the position.
Step 6 – Documentation, record-keeping, and voluntary self-disclosure
EAR compliance is only as strong as its documentation. BIS expects exporters and re-exporters to retain records of every export transaction – including the classification determination, the licence or exception relied upon, the party-screening results, the red-flag assessment, and the shipping documents themselves. The applicable record-keeping period under the EAR is five years from the date of the export, re-export, or transfer. That five-year window is not aspirational; it is the standard against which BIS will assess a compliance programme in the event of an inquiry.
For maritime operations, documentation should also extend to: the vessel IMO number at the time of booking and at loading; any AIS checks conducted; the date and result of any sanctions-list screening; and any red-flag assessment that was conducted and resolved. Where a flag changes or a vessel ownership appears to have altered, that fact and the response to it should be recorded.
If a potential violation is identified – a shipment that proceeded without a required licence, a party that was missed in screening, a re-export leg that was not assessed – the question of VSD (voluntary self-disclosure to BIS or OFAC, through which a business proactively reports a potential violation in exchange for a presumption of a reduced penalty) arises. BIS has a formal VSD process. Making a timely, complete, and accurate VSD, before BIS independently discovers the issue, is generally treated as a significant mitigating factor. However, the decision to disclose requires a careful analysis of the facts, the likely regulatory response, and any parallel criminal-exposure questions. That analysis should involve counsel before a disclosure is made.
What common errors should compliance teams avoid?
In our practice advising shipping companies, exporters, and freight intermediaries, the same failure modes recur across different sectors and shipping routes. Recognising them early is the most efficient form of risk management.
The most persistent error is treating EAR compliance as a one-time check at the point of export licence application. The EAR requires ongoing compliance through the full transaction lifecycle: at booking, at loading, at each re-export leg, and at the point of ultimate delivery. A licence or exception that was valid at filing may no longer be valid if circumstances change – the consignee is designated, the destination regime tightens, or the end-use shifts. Compliance is not a pre-shipment exercise; it is a lifecycle obligation.
A second recurring error is siloing OFAC screening from EAR screening. The party-screening obligation under the EAR (Entity List, Denied Persons List, Unverified List) is operationally distinct from OFAC SDN screening, but both apply to every maritime transaction with a US nexus. Programmes that run only one of the two list checks create a gap that BIS and OFAC have both exploited in enforcement actions.
A third error – one that is perhaps least visible until it is too late – is failing to assess the re-export obligations of foreign intermediaries in the supply chain. The EAR imposes obligations on the re-exporter. An exporter who sells to a foreign freight forwarder without informing that forwarder of applicable EAR controls, or without building appropriate contractual representations into the transaction, has not eliminated the risk; they have displaced it to a party who may not be in a position to manage it. That displacement can still expose the original exporter to liability if BIS finds that the exporter had reason to know of the intended re-export.
One myth worth correcting directly: the belief that re-routing a shipment through a third country that is not subject to EAR controls eliminates EAR jurisdiction. It does not. EAR jurisdiction follows the item, not the routing. A shipment of EAR-subject goods that transits a third country en route to a controlled destination is still subject to EAR re-export controls. Structural routing changes do not affect the jurisdictional analysis.
