Sanctions Screening Checklist for Port Suppliers
Six-step sanctions screening checklist for port suppliers: IMO number, flag, owner, DOC holder, charterer, insurance and payment terms before you quote.
Screen the vessel before you price the job, not after the stores are on the quay. A workable pre-quote check covers six items: IMO number, flag and registry, registered owner, DOC holder and technical manager, charterer or operator, and insurance plus payment terms.
That routine matters more this month. Washington is weighing relief for some shadow fleet tankers while the UK and EU tighten, so the same vessel can move from restricted to quotable in weeks. gCaptain reported on 15 October 2026 that the Trump administration is considering easing sanctions on vessels that have carried oil and petroleum products.
Why the ground shifted in October 2026
Sanctions lists are no longer moving in one direction. On 15 October, MarineLink reported Brent little changed as investors weighed possible US steps to ease restrictions on the shadow fleet, with a Middle East risk premium still in the market.
The same week, gCaptain reported that Britain expanded its measures against Russia's oil industry, targeting two more energy companies and a dozen shadow fleet tankers. The EU released its largest sanctions package on Russian defence-industry companies, from top yards to small suppliers, according to The Maritime Executive.
For a chandler, bunker supplier, agent or yard, that means a list check done in September may already be out of date. Build the check into the quote, and date the result.
The six-step screening checklist
Run the steps in order. Each one either clears the vessel or sends the enquiry to a second pair of eyes before anyone prices stores, bunkers or a repair window.
1. Confirm the IMO number, not just the name
Vessel names change with owners, managers and flags. The IMO number stays with the hull for life, so it is the only reliable key for every later check.
- Match the IMO number on the enquiry to the vessel in AIS and in the port call record.
- Flag a mismatch between the name given and the name shown against that IMO number.
- Check the MMSI in AIS points to the same vessel, since spoofing near high-risk straits has been reported.
2. Check the flag and registry status
The flag tells you which administration issues the certificates and how quickly it responds to a query. A recent reflagging is a prompt to look closer.
gCaptain reported on 12 October 2026 that Swedish authorities cleared the sanctioned tanker Sea Owl 1 to leave after nearly seven months at anchor, following confirmation that the vessel was now legitimately registered under a new flag. Registration changes are exactly the moment to re-run the check.
3. Identify the registered owner
The registered owner is the legal party on the certificate of registry, and it is often not the company your contact works for. Ownership sits behind layers of managers, and a sanctioned owner can appear under a name you have not seen before.
- Record the registered owner exactly as written, including any single-ship company name.
- Check the owner and its known addresses against the applicable lists.
- Note the date of the check, because ownership moves.
4. Find the DOC holder and technical manager
The Document of Compliance holder is the company that runs the safety management system, and it usually controls purchasing decisions for technical stores and repairs. This is the party that will actually approve your quote.
Splash247 reported on 16 October 2026 that Greek tanker owner Chemnav Shipmanagement expanded its suezmax newbuilding programme with two more vessels in China, taking its orderbook in the segment to four ships. Newbuildings mean new management arrangements, so the DOC holder on a 2027 delivery may not be the name on the order today.
5. Establish the charterer or operator
On a time charter the charterer fixes the voyage and often appoints the agent, while the owner still carries the asset risk. Both parties belong in the file.
- Ask the agent or the vessel directly who is paying for this port call.
- Confirm whether the enquiry is time charter, voyage charter or owner's account.
- Check the charterer against the same lists as the owner.
6. Verify insurance and agree payment terms
Insurance and payment terms are the last gate before the quote goes out, and they are where most supplier losses actually start.
P&I cover sits with the vessel's club, and the club landscape is shifting. Splash247 reported on 14 October 2026 that China Shipowners Mutual Assurance Association has formally applied to join the International Group of P&I Clubs, which would bring a mainland Chinese insurer into the group for the first time.
- Confirm the P&I club and the certificate of entry before delivery.
- For high-risk ports, check war risk cover separately from hull and machinery.
- Agree the PDA or proforma amount, currency and payment date in writing.
- For a first-time counterparty, ask for part payment or a bank reference.

Six steps per enquiry is manageable. Six steps per enquiry across a dozen vessels a week is not, unless the data is in one place.
- Record the date and the list version used for every check.
- Keep one file per vessel with the IMO number, owner, DOC holder and charterer.
- Re-run the check when the flag, owner or charterer changes.
- Escalate anything unclear to a named person instead of guessing.
Sanctions screening is not only a compliance task. A vessel that clears the check is a vessel you can quote with confidence, and a clean file makes the follow-up call easier.
How VesselReach helps
VesselReach puts the vessel picture and the outreach in one workflow, so screening and quoting start from the same record.
- Vessel intelligence shows vessels near your ports and expected arrivals, which means you can start the six checks before the ETA rather than after the agent calls.
- AI company targeting identifies the right company behind each vessel, which means the owner, manager or charterer you screen is the one that actually buys.
- Decision-maker discovery finds operations, technical and procurement contacts by role, so a cleared vessel turns into a conversation with the person who approves the spend.

Frequently asked questions
What is sanctions screening for port suppliers?
Sanctions screening for port suppliers is the pre-quote check that confirms who you are really dealing with before you price stores, bunkers or repairs. It covers six items: IMO number, flag and registry, registered owner, DOC holder and technical manager, charterer or operator, and insurance plus payment terms.
Why does sanctions screening matter more in October 2026?
Lists are moving in both directions. The US is weighing relief for some shadow fleet tankers while the UK and EU have tightened measures, so a vessel's status can change within weeks of your last check. Source: gCaptain
Why should I screen by IMO number instead of vessel name?
Vessel names change with owners, managers and flags, while the IMO number stays with the hull for life. Match the IMO number on the enquiry to AIS and the port call record, and treat a name or MMSI mismatch as a red flag.
What does a recent reflagging tell me about a vessel?
It tells you to re-run the check. Swedish authorities cleared the sanctioned tanker Sea Owl 1 to leave after nearly seven months at anchor once it was confirmed to be legitimately registered under a new flag, so registry changes are a screening trigger. Source: gCaptain
Should I check the charterer as well as the registered owner?
Yes. On a time charter the charterer fixes the voyage and often appoints the agent, so it is the party paying for the port call. Screen the charterer and the registered owner against the same lists, and record both in the vessel file.
How can I run this screening before the vessel arrives?
VesselReach shows vessels near your ports and expected arrivals, identifies the company behind each vessel and finds the right operations, technical or procurement contact, so the six checks and the quote can start ahead of the ETA. Book a demo.
