Sanctions Screening vs AML: What Ship Suppliers Check

Sanctions screening vs AML: the short answer

Sanctions screening checks whether a vessel, its owner, manager or flag appears on a restricted-party list. AML and KYC checks whether the counterparty you are about to invoice is who they claim to be, and where the money comes from. For a ship chandler, agent or yard, sanctions screening is vessel-facing and daily; AML/KYC is counterparty-facing and triggered when credit, cash or a new account is involved.

The two are often bundled under one label, which is why searches for sanctions screening vs aml and for what compliance means in practice keep returning the same vague answer. They are different checks, against different lists, producing different evidence. This article separates them for the people who actually deliver stores, bunkers, agency services and repairs to a vessel on a port call.

What sanctions screening actually covers

Sanctions screening is the process of checking a vessel and the companies behind it against restricted-party designations. It runs before you quote, before you load the truck and before you send the PDA, because a match can stop the port call entirely. The unit of screening is the vessel and its ownership chain, not the purchase order.

The EU's latest expansion shows how quickly the target list moves. On 12 October 2026 the European Union imposed sanctions on some of Russia's most important shipyards, including major submarine builders, naval ship-repair facilities and yards involved in commercial vessel construction, as part of a sweeping expansion (gCaptain). For a repair yard or a chandler serving a yard, that is not abstract policy. A named entity can sit one or two layers up the ownership chain from the vessel that just requested a quotation.

Vessel-level designations travel with the ship, not the port. The Russian-flagged Ro-Ro cargo ship Lady Mariia (IMO 9220641) passed through the Strait of Gibraltar on 29 August and was reported loitering off Port Said, having previously been sanctioned (The Maritime Executive). A sanctioned vessel does not stop being sanctioned because it is waiting off a new port. That is why the IMO number, not the vessel name, is the primary key for any screening record; names change, IMO numbers do not.

The lists that matter to a supplier

• Designated parties: entities and individuals named by the EU, UK, US and other authorities, including shipyards and naval repair facilities.
• Vessel designations: specific IMO numbers flagged as sanctioned, restricted or subject to port and service bans.
• Flag and ownership risk: flags, registered owners, technical managers and DOC holders linked to designated parties.
• Trade and cargo restrictions: cargoes and trades that cannot be served even when the vessel itself is not listed.

What AML and KYC actually cover

AML and KYC are counterparty checks. Anti-money-laundering rules ask whether the payment you are about to receive could be the proceeds of crime or a sanctions evasion channel. Know-your-customer rules ask whether the company and the person signing the order are real, authorised and traceable. The unit of screening is the customer account or the transaction, not the hull.

In maritime services, AML/KYC is usually triggered by one of four events: a new account or credit line, a request for extended terms, a cash or third-party payment, or a change of controlling party. A chandler opening a credit account for a ship manager will run KYC on the manager, the registered owner and the beneficial owner behind them. A bunker supplier extending 30-day terms after a PDA will do the same. The evidence produced is different from sanctions screening: it is identity, ownership and source-of-funds documentation, not a list hit or no-hit record.

Why the two get confused

Both checks use the same raw material: company names, IMO numbers, addresses, flags and directors. Both are performed before the service is delivered. Both produce a file that an auditor or a bank may later ask for. The difference is the question being asked. Sanctions screening asks whether you are allowed to serve this vessel at all. AML/KYC asks whether you should be doing business with this customer, on these terms, with this money.

The five-step screening routine suppliers can run

A repeatable routine beats a one-off check, because lists change and ownership chains are re-cut. The sequence below works for a chandler, bunker supplier, agent or yard, and it produces a file you can show a bank or an auditor.

1. Capture the IMO number first. Screen the hull, not the name. Record the vessel name, IMO number, flag and current registered owner at the moment of the enquiry.
2. Map the ownership chain. Identify the registered owner, technical manager, commercial operator and DOC holder. Any of these can be the designated party.
3. Run the sanctions check. Check each entity and the vessel against the applicable lists, and record the date and list version used.
4. Run AML/KYC only if a credit or payment exposure exists. Verify the contracting entity, its directors and beneficial owners, and document the source of funds.
5. Re-screen on change. Re-run the check when the vessel changes manager, when a new account is opened, or when a new designation is announced.

Why the list is never static

Sanctions designations arrive in waves, and each wave reshapes the risk profile of vessels already in your pipeline. The EU's October 2026 expansion captured submarine builders, naval ship-repair facilities and commercial yards in one move (gCaptain). Yards that were clean last quarter can be designated this quarter, and the vessels they manage or repair inherit the exposure.

Vessel behaviour adds a second layer. Satellite navigation can no longer be taken for granted in some of the world's busiest shipping regions, and the UK Maritime and Coastguard Agency's Marine Guidance Note MGN 719 urges crews to practise navigating without GPS as jamming and spoofing become more widespread (Splash247). When position reporting is unreliable, a supplier cannot lean on AIS alone to confirm where a vessel has been or what it has called at. The compliance file has to carry the documentary evidence, not just the live track.

Security incidents reinforce the same point. Bulgaria sent a frigate to search for evidence after two cargo ships were struck in the Black Sea area in October 2026 (The Maritime Executive). In a disrupted region, the vessels that keep trading are exactly the ones whose ownership, insurance and sanction status get examined hardest by banks, ports and suppliers.

What this means for chandlers, agents and yards

The commercial effect is procedural, not philosophical. A port call that fails screening costs you the order and, if the vessel is already alongside, the delivery cost as well. A KYC file that is missing when your bank asks for it can freeze a receivable. Both are avoidable with a routine, and both are more likely to be triggered when trade is busy.

Trade is busy. Global shipping earnings reached another milestone in October 2026, with Clarksons Research's cross-sector ClarkSea Index surging 12% in a week to an unprecedented $84,951 a day, its fifth consecutive all-time high (Splash247). More port calls mean more quotations, more new accounts and more screening decisions per week. Suppliers who treat screening as a one-time onboarding step will find the volume outruns the process.

Fleet renewal adds new counterparties at the same time. MISC is preparing five more LNG carrier newbuildings in China after a fresh long-term charter award from Petronas, with the ships expected to enter service from 2030 (Splash247). Newbuildings mean new registered owners, new technical managers and new DOC holders, all of which need to be screened before the first port call, not after the first invoice.

How VesselReach helps

VesselReach is the maritime sales intelligence platform that turns vessel movements at your chosen ports into screened, targeted conversations. It fits the compliance routine above because the vessel data and the outreach data sit in one workflow.

Vessel intelligence and IMO-level targeting. VesselReach detects vessels currently near your selected ports, plus scheduled and expected arrivals, so you can screen and qualify a vessel before it arrives rather than after it docks. Because each record is tied to the hull, your team works from the IMO number as the primary key, which means the screening file and the sales file refer to the same vessel.

AI company targeting and decision-maker discovery. The platform's AI identifies the relevant company behind each vessel, whether that is the ship manager, owner, operator, technical manager or charterer, and then finds the decision-makers in operations, port operations, commercial, chartering, fleet, procurement and the C-suite. That matters for compliance because the entity you screen is the entity you approach.

Multichannel outreach with human control. Outreach runs across email, WhatsApp and phone calls, personalised and staged rather than blasted, with automated follow-ups that stop when a prospect opts out. AI enquiry handling answers incoming questions from approved, verified information and escalates to a human representative when it cannot answer reliably, and the Android and iOS apps let that representative take the call. Humans stay in control of who is contacted and when.

If your team is screening vessels by hand while chasing port calls from a spreadsheet, book a VesselReach demo and see the workflow end to end. A 10-day free trial is offered after the demo meeting.

FAQ

Is sanctions screening the same as AML/KYC?

No. Sanctions screening checks the vessel, its IMO number, owner, manager and flag against restricted-party lists, and it runs on every enquiry. AML/KYC checks the customer entity, its directors and beneficial owners, and it is triggered by credit, cash or a new account. Different lists, different evidence, different owners inside your business.

What is sanctions screening in KYC and AML terms?

In KYC and AML frameworks, sanctions screening is the control that confirms the customer and the underlying transaction are not linked to a designated party. For a ship supplier it is vessel-facing: you screen the hull and the ownership chain before you quote, then record the result, date and list version in the customer file.

Which lists should a ship chandler screen against?

Designated-party lists from the EU, UK, US and other relevant authorities, vessel-specific designations identified by IMO number, and flag or ownership links to designated entities. The EU's October 2026 expansion, which targeted Russian shipyards including naval repair facilities, shows how quickly the entity list moves.

How often should a supplier re-screen a vessel?

Re-screen when the vessel changes manager or owner, when a new account is opened, when a payment method changes, and whenever a new designation is announced. Treat screening as a live control tied to the port call, not as an onboarding step completed once.

What evidence should a chandler keep for a compliance file?

For sanctions: the screening result, the date, the list version and the IMO number used. For AML/KYC: identity documents, an ownership chart, source-of-funds evidence and a risk rating. Keep both sets together, because banks and auditors increasingly ask for the vessel and the counterparty in one file.

Can a supplier rely on AIS to verify a vessel's history?

Not on its own. Jamming and spoofing are widespread enough that the UK Maritime and Coastguard Agency's MGN 719 urges crews to practise navigating without GPS. Documentary evidence such as screening records, port call history and ownership documents should carry the compliance file, with AIS as a supporting signal.
