Breaking — May 9, 2026: Iran has been charging vessels over $1 million per ship to transit the Strait of Hormuz — and the US has now officially warned that any shipping company paying these tolls risks being hit with severe sanctions. The US Office of Foreign Assets Control (OFAC) issued a formal alert warning that payments to Iran for Hormuz passage — in any form including cash, digital assets, charitable donations, or informal swaps — constitute sanctions violations. For Dubai cargo shippers, this creates a dangerous legal minefield on top of an already complex logistics crisis.
What Is Iran’s Hormuz Toll System?
After closing the Strait of Hormuz to Western vessels in February 2026, Iran began offering some ships “safe passage” through a detour route closer to its shore — but at a price. Iran has been charging tolls of over $1 million per vessel for safe transit authorization. Payment options demanded have included fiat currency, digital assets, informal offsets and swaps, and even “charitable donations” to the Iranian Red Crescent Society, Bonyad Mostazafan, or Iranian embassy accounts. On May 5, 2026, Iran formally institutionalized this system by establishing the Persian Gulf Strait Authority — a new government body created specifically to authorize and regulate maritime transit through Hormuz.

OFAC Warning — What It Says Exactly
The US Office of Foreign Assets Control posted its formal alert on May 2, 2026. The alert states clearly that both US persons and non-US persons risk sanctions for making payments to Iran or the IRGC for Hormuz safe passage — regardless of the payment method used. OFAC specifically warned about payments disguised as charitable donations to Iranian Red Crescent Society, Bonyad Mostazafan, or Iranian embassy accounts. The alert also warned that vessels transiting through Iranian territorial waters — the IRGC’s “alternative route” past Larak Island — face enhanced scrutiny. Service providers including insurers, reinsurers, banks, and financial institutions that facilitate such payments also face sanctions exposure. OFAC urged all maritime service providers to conduct enhanced due diligence on vessels transiting Hormuz and to ask counterparties whether any safe passage fees were paid to Iran.

OFAC Sanctions Risk — Who Is Affected
| Party | Sanctions Risk | Specific Exposure |
|---|---|---|
| Shipping companies (US-based) | 🔴 Prohibited | Criminal and civil liability for any toll payment |
| Shipping companies (non-US) | 🔴 High risk | Civil/criminal if payment causes US person violation |
| Freight forwarders | 🟠 Significant | If facilitating toll-paying shipments |
| Insurance companies | 🔴 High risk | If insuring toll-transiting vessels |
| Banks and financial institutions | 🔴 High risk | If processing toll-related payments |
| Digital asset exchanges | 🔴 High risk | If processing crypto toll payments to Iran |
| Ship owners (non-Western) | 🟡 Elevated | Enhanced scrutiny — must document no toll paid |
The “Dual Blockade” — US Counter-Blockade of Iranian Ports
Following the failure of the Islamabad Talks on April 12, the US Navy launched its own counter-blockade of Iranian ports on April 13 — preventing Iranian tankers from leaving and cutting off Iran’s oil revenue. The Guardian described the situation as a “dual blockade” — Iran blockading the Gulf through Hormuz, and the US blockading Iran’s own ports simultaneously. US Central Command reported that 45 commercial ships had been told to turn around since the US blockade began. Iranian President Masoud Pezeshkian called the siege of Iranian ports “intolerable.” Trump subsequently warned that any Iranian infrastructure associated with nuclear or military programs would face strikes if Hormuz was not reopened.

What This Means for Dubai Shippers — Practical Impact
For Dubai cargo shippers using freight forwarders, the OFAC warning creates a compliance obligation. If your freight forwarder routes cargo through a vessel that paid Iran a Hormuz toll, your company could theoretically face sanctions exposure. You must now ask your freight forwarder and carrier explicitly: “Has this vessel paid any fees or tolls to Iran or the IRGC for Hormuz transit?” Carriers using the IRGC alternative route past Larak Island must be asked whether any payments were made. Documentation proving no toll was paid should be kept on file. The safest approach: avoid Gulf routing entirely and use Hormuz-independent alternatives. Full alternative routing options: Khor Fakkan Port 2026 Guide, MSC Saudi Land Bridge Route, and Fujairah Port 2026 Guide.
Shipping Costs — Toll Route vs Safe Alternatives
| Option | Cost | Sanctions Risk | Recommended? |
|---|---|---|---|
| Iran toll route (Hormuz direct) | $1M+ toll + war risk surcharge | 🔴 High — OFAC violation risk | ❌ No |
| Khor Fakkan sea route | $1,200–$1,800 FCL 20ft | ✅ Zero sanctions risk | ✅ Yes |
| Land freight to Saudi/Oman | AED 180–280 per 100kg | ✅ Zero sanctions risk | ✅ Yes |
| MSC Saudi land bridge (Europe) | $2,800–$4,000 FCL 20ft | ✅ Zero sanctions risk | ✅ Yes |
| Air cargo DXB | AED 18–28 per kg | ✅ Zero sanctions risk | ✅ For urgent only |
China’s Role — Walking a Tightrope
Chinese Ambassador to the UN Fu Cong stated that “maintaining the ceasefire is the most urgent issue” and confirmed China supports Pakistan’s mediation efforts. However, China also vetoed the UN Security Council resolution on Hormuz and Chinese vessels have been among the few permitted to transit via the IRGC alternative route. For Dubai shippers working with Chinese freight partners or using Chinese-flagged vessels, the question of whether those vessels paid Iranian tolls has now become a legal compliance issue under OFAC. Chinese companies transacting in US dollars or with US financial institutions face particular exposure. On May 7, the Chinese chemical tanker JV Innovation was attacked — the first Chinese vessel targeted during the crisis — signaling that even China’s permitted status may be unreliable.

Frequently Asked Questions — Iran Hormuz Toll and OFAC Sanctions 2026
What is Iran’s Hormuz toll and how much does it cost?
Iran has been charging over $1 million per vessel for authorized transit through the Strait of Hormuz via its alternative route past Larak Island. Payments can be in cash, digital assets, informal swaps, or donations to Iranian-linked organizations. On May 5, 2026, Iran formally institutionalized this through the Persian Gulf Strait Authority.
Can Dubai-based companies pay Iran’s Hormuz toll legally?
No — not without extreme legal risk. OFAC’s alert applies to non-US persons as well as US persons. Any payment that causes a US person — such as a US-based insurer, bank, or reinsurer — to violate sanctions creates criminal and civil liability. UAE companies using US dollar transactions or US financial institutions face particular exposure.
If my freight forwarder routes cargo through a toll-paying vessel, am I at risk?
Potentially yes — which is why you must now ask your freight forwarder explicitly whether vessels used have paid Iranian transit fees. Request written confirmation and keep it on file. If your forwarder cannot confirm no toll was paid, request alternative routing via Khor Fakkan or land corridors.
Are Chinese vessels paying Iran’s toll?
Some Chinese vessels may be paying tolls or using informal arrangements for Hormuz transit. The OFAC alert specifically mentions digital asset payments — which Chinese operators may use to avoid dollar-denominated transactions. However, on May 7, even a Chinese vessel was attacked — suggesting Iran’s tolerance for Chinese transit may be unreliable.
What is the Persian Gulf Strait Authority established by Iran on May 5?
It is a new Iranian government body created to formally authorize and regulate maritime transit through the Strait of Hormuz. Any vessel seeking to transit must now contact this authority. It formalizes what was previously an ad hoc toll collection system into an official regulatory framework — which the US considers illegal under international maritime law.
What should Dubai shippers do to avoid sanctions risk?
Use Hormuz-independent routes exclusively. Ask your freight forwarder and carrier in writing whether any Iranian transit fees have been paid on your cargo’s vessel. Keep documentation on file. Use Khor Fakkan, Fujairah, land routes, or MSC’s Saudi land bridge for all shipments. See complete current options: Dubai Cargo Update May 2026.
