# Iran's Hormuz Blacklist Doubles: Supplier Checks > Iran's PGSA list of non-compliant ships has almost doubled to 240, with all Sinokor vessels targeted. What chandlers, bunker suppliers and agents must check. URL: https://vesselreach.si/blog/irans-hormuz-blacklist-doubles-supplier-checks | Published: 2026-11-03 | Industry news | Topic: Carrier service and surcharge changes ## In short Iran's Persian Gulf Strait Authority almost doubled its non-compliance list to 240 ships and confirmed that all Sinokor vessels will be treated as blacklisted tonnage, according to Seatrade Maritime News (2 November 2026). For chandlers, bunker suppliers and port agents in Gulf ports, that means screening every enquiry against both the US measures and the PGSA list before quoting. ## Key takeaways - The PGSA non-compliance list grew from roughly 120 to 240 ships, with Kuwait Oil Tanker Company and Sinokor fleets named in the same report. - A vessel can now be flagged by Washington and by Tehran for different reasons, so suppliers must screen against both lists on the day they quote. - Chandlers should default to cash-and-carry terms or a bank guarantee for first stems from unfamiliar managers of listed tonnage. - Port agents should add a war-risk and screening line to the PDA instead of absorbing that cost silently on every Hormuz call. - Screen by IMO number, confirm whether the buyer is owner, manager or trader, and price screening and attendance as visible lines. ## At a glance - **What: What did Iran change in the Strait of Hormuz?** Iran's Persian Gulf Strait Authority almost doubled its non-compliance list to 240 ships and confirmed all Sinokor vessels will be treated like those already blacklisted. ([Seatrade Maritime News](https://www.seatrade-maritime.com/security/iran-doubles-hormuz-blacklist-with-sinokor-kotc-fleets-targeted)) - **Who: Which fleets are named in the widened list?** Sinokor and Kuwait Oil Tanker Company fleets are targeted, according to Seatrade Maritime News, alongside the wider set of ships already on the PGSA non-compliance list. ([Seatrade Maritime News](https://www.seatrade-maritime.com/security/iran-doubles-hormuz-blacklist-with-sinokor-kotc-fleets-targeted)) - **Where: Where does the blockade apply?** The US naval blockade targets Iranian ships and ports, while Iran's own list governs transits through the Strait of Hormuz, so the two regimes overlap in Gulf waters. ([The Maritime Executive](https://maritime-executive.com/article/the-blockade-on-iran-is-deepening-but-also-widening)) - **When: When was the widened list reported?** Seatrade Maritime News reported the doubling of the PGSA non-compliance list to 240 ships on 2 November 2026. ([Seatrade Maritime News](https://www.seatrade-maritime.com/security/iran-doubles-hormuz-blacklist-with-sinokor-kotc-fleets-targeted)) - **Why: Why does Iran still move some cargo?** gCaptain reported in October 2026 that Iran has managed to export some LPG and jet fuel since July despite the US naval blockade, according to shipping intelligence and security sources. ([gCaptain](https://gcaptain.com/iran-ships-some-lpg-jet-fuel-despite-us-blockade-data-shows/)) - **How: How do shadow fleet practices undermine enforcement?** A 2026 paper in Humanities and Social Sciences Communications found shadow fleets carry out AIS manipulation, illicit ship-to-ship transfers and operate aging, poorly maintained vessels, while the IMO response stays reactive. ([Humanities and Social Sciences Communications (Palgrave Macmillan)](https://doi.org/10.1057/s41599-026-08775-8)) Iran's Persian Gulf Strait Authority has almost doubled its non-compliance list to 240 ships and confirmed that all Sinokor vessels will be treated like blacklisted tonnage, according to [Seatrade Maritime News](https://www.seatrade-maritime.com/security/iran-doubles-hormuz-blacklist-with-sinokor-kotc-fleets-targeted) (2 November 2026). For a chandler, bunker supplier or port agent working Gulf ports, that turns a sanctions question into a quoting question. ## What changed in the Strait of Hormuz The PGSA (Persian Gulf Strait Authority, the Iranian body that administers its own rules for Hormuz transits) widened its non-compliance list from roughly 120 to 240 ships. Kuwait Oil Tanker Company fleets and the Sinokor fleet are named in the same report. This sits inside a wider squeeze. The White House says its blockade of Iran's energy shipping has been 100 percent effective, and [The Maritime Executive](https://maritime-executive.com/article/uani-iran-s-lpg-carriers-can-get-through-u-s-navy-blockade-but-rarely) (3 November 2026) reports that the numbers largely support the claim. An earlier assessment in the same publication described the blockade as deepening and widening ([The Maritime Executive](https://maritime-executive.com/article/the-blockade-on-iran-is-deepening-but-also-widening), 23 October 2026). Iran still moves some cargo. [gCaptain](https://gcaptain.com/iran-ships-some-lpg-jet-fuel-despite-us-blockade-data-shows/) (16 October 2026) reported that Iran has managed to export some LPG and jet fuel since July despite the blockade. ## Why two lists matter more than one A vessel can now be exposed to two separate authorities with different criteria. The US blockade targets Iranian ships and ports; the Iranian list targets ships it deems non-compliant with its own transit rules. That produces a middle group: tonnage that is legal for one side and flagged by the other. Peer-reviewed work on the same problem describes the mechanism. A 2026 paper in *Humanities and Social Sciences Communications* found that shadow fleets engage in systematic violations including AIS manipulation, illicit ship-to-ship transfers and the operation of aging, poorly maintained vessels, and that the IMO's response remains reactive and fragmented ([Palgrave Macmillan](https://doi.org/10.1057/s41599-026-08775-8)). A second 2026 paper in *Lex Portus* argues that flag-state enforcement of administrative penalties against dark fleet vessels is structurally weak under UNCLOS monitoring obligations ([Lex Portus](https://doi.org/10.62821/lp12103)). In practice, the supplier carries more of the screening burden than the flag registry does. ## What it means commercially for maritime service providers The commercial effect is not a shortage of enquiries. It is a change in which enquiries a supplier can accept, and at what price. - **Ship chandlers:** a 240-ship list means more owners asking for stores at short notice with unusual payment routes. Cash-and-carry terms, or a bank guarantee, become the default for first stems from unfamiliar managers. - **Bunker suppliers:** a stem for a listed vessel ties up barge time and credit. A stem (a confirmed order for a specific quantity and grade of bunkers on a given date) fixed against a vessel that cannot safely complete the port call is a loss on both counts. - **Port agents:** the PDA (pro forma disbursement account, the estimate of port costs sent to the owner before the call) needs a war-risk and screening line. Agents who absorb that cost silently lose margin on every Hormuz call. - **Repair yards and marine service companies:** attendance on a listed vessel may need permits, and a superintendent may not travel. Mobilisation cost rises before any work is quoted. The pricing side of this is covered in more detail in [pricing Gulf port call work under Hormuz risk](https://vesselreach.si/blog/hormuz-shipping-risk-pricing-gulf-port-call-work), and the freight side in [where Hormuz tanker freight work lands](https://vesselreach.si/blog/hormuz-tanker-freight-where-the-work-lands). ## A screening routine before you quote Run the same five checks on every Gulf enquiry, in this order, and record the result in the file. 1. **Identify the vessel properly.** Use the IMO number (the permanent seven-digit hull identifier that does not change with the ship's name or flag) rather than the name alone. 2. **Check the current lists.** Screen against both the US measures and the PGSA non-compliance list, and note the date you checked. 3. **Confirm who is buying.** Establish whether the counterparty is the owner, the technical manager or a trader. A commercial trader with no DOC holder (the company holding the Document of Compliance under which the ship is operated) relationship is a different credit decision. 4. **Price the risk explicitly.** Quote the screening and attendance cost as a line, not inside a lump sum. 5. **Set the payment condition.** For unfamiliar counterparties, ask for payment before delivery or a guarantee, and say so in the quotation. None of this is new legal work. It is the same discipline that [vessel vetting](https://vesselreach.si/blog/vessel-vetting-what-it-means-for-suppliers) already asks of suppliers, applied to a list that now changes faster. ## Where the next wave of enquiries comes from Two other stories this week point the same way. [Hellenic Shipping News](https://www.hellenicshippingnews.com/slowing-intra-asia-chemical-palms-spot-freight-fixtures-deter-trades/) (2 November 2026) reports that tanker freight in Asia has stayed buoyant into November, with a tanker pile-up at ports curtailing tonnage supply in South East Asia and India. Congestion plus rerouting means more vessels waiting, and waiting ships buy water, provisions and lubricants. The same outlet's dry bulk analysis notes India's draft National Steel Policy targeting 531 million tonnes of crude steel production by 2047 ([Hellenic Shipping News](https://www.hellenicshippingnews.com/could-indias-steel-vision-2047-create-the-next-breakthrough-for-dry-bulk-demand/), 2 November 2026). Longer-term iron ore and coking coal flows through Indian ports widen the base of vessels a Gulf or Indian Ocean supplier can serve outside the sanctioned segment. The practical conclusion for a sales team is to work both ends. Keep a compliant book that grows with legitimate cargo, and treat the listed tonnage as a credit and compliance decision rather than a sales target. ## How VesselReach helps Screening decisions are only useful if your team reaches the right counterparty before the vessel sails. VesselReach turns vessel movements at your chosen ports into conversations with the people who decide. - **Vessel intelligence:** see vessels near your ports and expected arrivals, which means your team can qualify a Gulf enquiry days before the ETA rather than after the agent calls. - **AI company targeting and decision-maker discovery:** VesselReach identifies the company behind each vessel and finds operations, chartering, procurement and fleet contacts by role, which means you screen the buyer and the vessel in the same step. - **Email, WhatsApp and phone outreach with AI enquiry handling:** enquiries are answered from your approved information and escalated to a human when the answer is not verified, which means compliance-sensitive questions reach a person, not a guess. Book a VesselReach demo to run the workflow on your own ports, with a 10-day free trial offered after the meeting. ## Frequently asked questions ### How many ships are on Iran's Hormuz non-compliance list? The PGSA non-compliance list almost doubled to 240 ships, according to Seatrade Maritime News in November 2026. The same report states that all Sinokor vessels will be treated similarly to those already blacklisted. ([Seatrade Maritime News](https://www.seatrade-maritime.com/security/iran-doubles-hormuz-blacklist-with-sinokor-kotc-fleets-targeted)) ### Is the US blockade of Iran's energy shipping working? The White House maintains the blockade has been 100 percent effective, and The Maritime Executive reports that the numbers largely back the claim. gCaptain reported in October 2026 that Iran still shipped some LPG and jet fuel since July. ([The Maritime Executive](https://maritime-executive.com/article/uani-iran-s-lpg-carriers-can-get-through-u-s-navy-blockade-but-rarely)) ### Should a ship chandler refuse a listed vessel? Refusal is a commercial decision, not a legal one. Many suppliers instead quote with explicit screening costs and payment before delivery or a guarantee for unfamiliar counterparties, so the risk is priced rather than absorbed. ### What documents should a port agent check before a Hormuz port call? Confirm the vessel by IMO number, screen it against both US measures and the Iranian list on the day you quote, identify whether the buyer is owner, manager or trader, and record the DOC holder relationship before fixing a PDA. ### Why does tanker congestion in Asia matter to Gulf suppliers? Hellenic Shipping News reports in November 2026 that a tanker pile-up at ports is curtailing tonnage supply in South East Asia and India. Waiting vessels still need provisions, water and lubricants, so demand shifts to the congested ports. ([Hellenic Shipping News](https://www.hellenicshippingnews.com/slowing-intra-asia-chemical-palms-spot-freight-fixtures-deter-trades/)) ### How can a maritime supplier find the right contact before a vessel arrives? VesselReach detects vessels near your chosen ports and expected arrivals, identifies the company behind each vessel and finds decision-makers by role, so outreach reaches operations or procurement before the ETA rather than after the agent has already placed the order. ## Sources 1.

That matters to any chandler, bunker supplier or agent quoting Gulf port calls, because a vessel can now be flagged by Washington and by Tehran for different reasons. The workable response is a short screening routine: confirm the ship by IMO number, check both lists on the day you quote, identify whether the buyer is owner, manager or trader, then price screening and attendance as visible lines and ask for payment before delivery on unfamiliar counterparties. Treat listed tonnage as a credit decision, and keep growing the compliant book as Indian steel demand and Asian tanker congestion push more legitimate vessels through the region. --- VesselReach, built by CatalystIQ.
