A Swiss trading house has agreed terms on a shipment of industrial equipment to a buyer in a third market. Payment will route through a Zurich correspondent. The goods have dual-use potential. Before a single invoice is raised, the compliance team needs to know: does this transaction clear under Swiss sanctions law? And if SECO's rules pass it, will OFAC's extraterritorial reach still create a problem?
Trade-transaction screening under SECO means systematically checking each element of a proposed cross-border trade – the parties, the goods, the payment route, and the end use – against the ordinances administered by the State Secretariat for Economic Affairs (SECO, Switzerland's principal sanctions and export-control authority). The check must be done before commitment, not after. As of January 2026, Switzerland has adopted measures that track, though do not always replicate, the principal EU and UN regimes, giving SECO a broader reach than many cross-border businesses assume.
This guide walks through the screening process step by step, identifies the points at which SECO's approach diverges from OFAC, OFSI, and the EU, and explains when a matter calls for qualified sanctions counsel.
Step 1: Understand who administers Swiss sanctions and what legal authority they hold
SECO administers Swiss sanctions under the Federal Act on the Implementation of International Sanctions (the Embargo Act), supported by implementing ordinances issued for each targeted programme. The ordinances carry the operative prohibitions – asset freezes, financial restrictions, import and export bans, and services embargoes – and are updated by Federal Council decision, sometimes at short notice.
Switzerland is not a member of the European Union, so it does not automatically apply EU Council regulations. It adopts measures as a sovereign decision, ordinance by ordinance. In practice, Switzerland tracks most UN Security Council measures and a significant share of EU programmes, but the scope, timing, and precise wording can differ. A transaction that is prohibited under an EU regulation may fall within a narrower or differently structured Swiss ordinance – and vice versa. That divergence is material for any business operating across both jurisdictions.
SECO also administers export controls under the Federal Act on the Control of Dual-Use Goods, Specific Military Goods and Strategic Goods (the Goods Control Act). For trade transactions involving technology, chemicals, electronics, or items with both civil and military potential, the goods-control dimension runs in parallel with the sanctions screen. Both legs of the check are mandatory.
In our cross-border practice, businesses frequently run the sanctions screen and overlook the export-control overlay entirely – or treat them as a single, interchangeable exercise. They are not. Each has its own trigger, its own licensing authority, and its own penalty regime.
Step 2: Map every party and every role in the transaction
Before querying any list, identify every principal who touches the transaction. A complete party map for a trade transaction typically includes the buyer, the seller, the end user (if different from the buyer), the agent or broker, the freight forwarder, the insurer, the correspondent or intermediary bank, and any intermediate consignee named in the shipping documents.
Each of these roles creates a potential point of sanctions exposure. SECO's asset-freeze provisions apply to any person or entity included in the relevant ordinance's list or captured through a designated person's ownership or control. The ownership and control test under Swiss ordinances broadly follows the approach used in EU regulations: a non-listed entity that is owned or controlled by a designated person may itself be caught, even if the ordinance does not list it by name. The threshold and analytical method mirror EU guidance more closely than OFAC's mechanical 50 percent aggregation rule, meaning the Swiss analysis requires a judgement about effective control, not merely a percentage count.
Practically, this means mapping the beneficial ownership chain to the ultimate natural-person level for each corporate party. Where a counterparty has a complex holding structure – a frequent feature of trading companies operating through multiple jurisdictions – the mapping exercise can be the most time-consuming part of the screen. It is also the part most likely to be short-cut under deadline pressure.
Do not limit the map to named parties in the contract. If the shipping instructions name a transhipment port in a jurisdiction subject to a services or transport embargo under any ordinance, the shipping agent using that port is part of the transaction's exposure profile.
Step 3: Query the SECO lists and the UN Consolidated List against every mapped party
SECO maintains published lists of designated persons and entities under each active ordinance. These are available on the SECO website and are updated when the Federal Council amends an ordinance. The UN Consolidated List (maintained by the UN Security Council's 1267/1989/2253 Committee and related committees) is separately incorporated into Swiss law and should be queried in parallel, because the Swiss ordinance implementing a UN resolution may not always carry across every listed entry in the same format or with the same identifiers.
The practical query process involves three layers:
- Name matching against the SECO ordinance annexes for the relevant programme, using all known aliases, former names, and transliterations for each party.
- Identifier matching using any registration numbers, passport numbers, vessel IMO numbers, or other unique identifiers provided in the counterparty documentation.
- Indirect matching through the ownership chain: if a corporate party is owned or controlled by a listed person, screen that controlling person's entries across all active SECO ordinances and the UN Consolidated List.
Automated screening tools vary significantly in how they handle transliteration, partial-name matching, and structured-entity identifiers. In our experience, tools calibrated for OFAC SDN-list queries frequently underperform on the Swiss ordinance annexes, which use different identifier conventions. A hit rate that looks acceptable on OFAC screening may mask gaps on the SECO side. Validate tool coverage explicitly against SECO's published list format before relying on it.
Step 4: Screen the goods and their classification
Once the party check is complete, turn to the goods. Swiss sanctions ordinances can impose outright export or import bans on specific categories of goods destined for or originating from a targeted programme's scope. Those prohibitions operate independently of whether any individual counterparty is listed.
In parallel, the Goods Control Act requires an export licence for items on Switzerland's control lists – goods with dual-use characteristics, specific military goods, and certain strategic items. The control lists are defined by reference to international export-control arrangements (the Wassenaar Arrangement, the Nuclear Suppliers Group, the Australia Group, and the Missile Technology Control Regime), but the Swiss classification is domestically authoritative. An item classified under a US Export Control Classification Number (ECCN, the US Commerce Control List identifier) does not automatically map to the same Swiss control list entry: verify each classification independently.
The goods check therefore has two sub-steps: first, confirm whether the goods are subject to any sectoral prohibition in the relevant SECO ordinance; second, confirm whether they require an export authorisation under the Goods Control Act. Where both apply, both must be cleared before the transaction can proceed.
For trade transactions routed through intermediaries, apply the goods check to what is actually being shipped – not to the commercial description in the contract. Invoice descriptions that omit technical specifications, or that bundle multiple items under a single line, are a common source of misclassification and subsequent enforcement scrutiny.
Step 5: Assess the payment route and financial prohibitions
Switzerland's financial-services sector is deeply integrated into international trade finance. A transaction that would otherwise pass a Swiss goods-and-parties screen can still be blocked at the payment stage if the payment route touches a prohibited financial channel under a SECO ordinance or under OFAC's extraterritorial reach.
Under Swiss ordinances, financial prohibitions typically cover making funds or economic resources available to designated persons, processing payments through designated financial institutions, and in some programmes providing financing, insurance, or brokering services connected to prohibited activities. The precise scope varies by ordinance; check the operative text for the relevant programme.
The OFAC dimension is not hypothetical for Swiss businesses. Where a transaction is denominated in US dollars, clears through a US correspondent bank, involves a US-person counterparty, or has a nexus to the United States, OFAC's prohibitions apply regardless of where the Swiss party is located. Secondary-sanctions risk under OFAC programmes can arise even where the Swiss party has no US nexus, if the transaction involves a jurisdiction or a designated entity that triggers OFAC's secondary-sanctions authority. These are separate legal questions from the SECO ordinance analysis and must be assessed in parallel.
In a recent matter, a financial institution processing a trade-finance facility for a client cleared the transaction under the applicable Swiss ordinance without separately assessing the US-dollar clearing leg. The correspondent bank in New York applied its own OFAC screen and suspended the payment. The delay cost the client a material contractual penalty. A dual-track screen – SECO and OFAC simultaneously, not sequentially – would have identified the conflict before commitment.
The position above covers the standard case. Your facts – the currency, the correspondent bank, the counterparty's ownership chain, and the goods' specification – change the analysis.

Step 6: Evaluate the end-use and red flags
A clean party screen and a clear goods classification do not exhaust the compliance obligation. Swiss export-control law requires the exporter to assess end-use: will the goods be used for their stated commercial purpose, by the stated end user, in the stated destination? Where there is reason to doubt any of those elements, the transaction presents a red-flag issue that may require a specific licence application, additional contractual protections, or a decision not to proceed.
Red flags recognised across the major export-control regimes include:
- A buyer or end user unwilling to provide an end-user certificate or end-use statement.
- A proposed delivery route that involves unnecessary transhipment through a third country.
- Payment terms, currency, or banking arrangements inconsistent with the buyer's profile.
- A commercial quantity or specification of goods that does not match the stated end use.
- A buyer or intermediary with no apparent commercial presence in the delivery country.
- A request that the goods be delivered to a different address or person after the contract is signed.
The presence of one or more of these flags does not make a transaction prohibited. It triggers a due-diligence obligation to investigate further before proceeding. Under Swiss law, as under the EAR and EU dual-use rules, knowledge or a reasonable suspicion that the goods may reach a prohibited end use or end user is a condition for criminal liability. Documenting the investigation – and the conclusion – is therefore a substantive compliance requirement, not merely a record-keeping formality.
If a transaction has already been flagged internally or by a counterparty, or if a filing has been refused, an early review can preserve options that narrow with time. Write to our team at info@caldervance.com.
Step 7: Cross-check the other regimes that may bite
Switzerland's SECO screen is the primary compliance obligation for a Swiss-based transaction. It is rarely the only one. Depending on the parties, the goods, and the payment route, one or more of the following regimes will also apply and must be checked in parallel.
OFAC (United States): Any US-dollar transaction, US-person involvement, or goods of US origin or with US-origin content triggers OFAC jurisdiction. The de minimis threshold for US-origin content – the point at which US export-control rules follow the goods into a re-export – is a fact-specific determination that should be made before the transaction is committed, not when the correspondent bank returns the payment.
OFSI (United Kingdom): A UK-incorporated counterparty, a UK-based insurer, or a transaction involving sterling clearing creates UK jurisdiction under the Sanctions and Anti-Money Laundering Act ("SAMLA") and OFSI's financial-sanctions regime. UK ownership-and-control tests for determining whether a non-listed entity is caught closely track the EU approach and differ in practice from OFAC's mechanical rule.
EU sanctions: Swiss businesses with EU subsidiaries, EU-established counterparties, or goods passing through EU territory may be subject to EU Council regulations independently of the SECO ordinance. The EU has published extensive guidance on its ownership-and-control analysis, and the EU General Court has produced a body of case law on the standard of evidence required for designation challenges.
The UN Consolidated List: As noted above, this must be checked independently. UN measures form the floor beneath which no national regime may drop; in some programmes the UN list is narrower than the autonomous measures adopted by Switzerland, the EU, and others.
The governing principle across all these regimes is that the stricter prohibition governs. A transaction that Swiss law permits may still be blocked by OFAC. Run each check against its own applicable authority; do not assume that passing one screen clears the others.
Step 8: Document, escalate, and decide
A screening exercise that produces no actionable findings is only useful if it is documented. Regulators and enforcement authorities across all major regimes – SECO, OFAC, OFSI, and the EU – treat the quality of a compliance programme's records as evidence of whether the programme was genuine. Where a transaction later comes under scrutiny, the contemporaneous records of the screen are often the primary defence.
Documentation should capture: the date and the version of the lists queried; the query terms and identifiers used for each party; the result of each query; the goods classification applied and the basis for it; the red-flag assessment and any follow-up steps taken; and the name and role of the person who reviewed and approved the transaction.
Where the screen produces a hit or a flag, a documented escalation path is required. Most compliance programmes specify a tiered escalation: the first-line analyst escalates to the compliance officer; the compliance officer escalates to the General Counsel or external counsel where the hit involves a complex ownership chain, a potential licence requirement, or a possible voluntary self-disclosure. The escalation decision – and the reasoning – should be recorded in the same file as the screen itself.
Where a transaction is blocked or a decision is made not to proceed, record the basis. Where a transaction is approved after a red-flag review, record the investigation that satisfied the compliance officer. Where a licence is required, begin the application process before the commercial deadline for performance.
What happens when internal review reaches its limit? That is the moment for external counsel. In our experience, the matters that create the greatest enforcement exposure are not those where businesses identified a problem and documented their response – they are the ones where a flag was noted, the documentation stopped, and the transaction proceeded without a clear sign-off.

Common myths about Swiss sanctions compliance
One persistent myth is that Switzerland's neutrality provides a de facto commercial safe harbour. It does not. Swiss neutrality is a foreign-policy tradition; the Embargo Act and the implementing ordinances are hard domestic law. Breach of a SECO ordinance carries criminal sanctions under Swiss law, irrespective of the political character of the measures. A second misconception holds that because Switzerland is not an EU member, EU Council regulations do not apply to transactions executed in Switzerland. That is partially true for Swiss-only transactions, but it ignores the reality that most Swiss businesses operate through structures with EU nexus – EU subsidiaries, EU-based customers, or goods transiting EU territory – and those elements pull EU law back into scope.
A third myth, common among smaller trading firms, is that passing a bank's compliance screen is the same as completing the exporter's own legal obligation. Banks run screens for their own risk; those screens are not calibrated to the exporter's goods-classification obligations or to the end-use assessment required under the Goods Control Act. The bank's clearance is not a legal opinion addressed to the exporter. Both the exporter and the bank carry independent obligations, and each can be held liable independently.
