IRISL Loads Ships With Missile Materials at Chinese Chemical Port, Sails to Iran

Iran-bound chemical shipments

The vessels loaded sodium perchlorate, a chemical mainly used for rocket propellant and fireworks, and then sailed for Iran.

Washington says the movement could feed Iranian weapons programs.

Beijing denied direct assistance and argued that U.S. accusations overstate routine commercial or dual‑use trade.

Reporting notes that two vessels left the Gaolan terminal this week bound for Iran according to ship-tracking, satellite imagery and Treasury Department records.

IRISL vessel movements

Tracking and maritime data cited in the reporting indicate at least 12 IRISL vessels have visited the same Gaolan terminal this year.

Specific ships, including the Barzin and Shabdis, were identified as known perchlorate haulers.

Analysts flagged that some vessels made near‑daily calls in mid‑February as U.S. forces massed near Iran and nuclear talks stalled.

Links were drawn to a deadly blast at Shahid Rajaee last year that experts associated with a chemical fire showing signs consistent with perchlorates.

IRISL departures and concerns

Reporting points to evidence from ship-tracking, satellite imagery and Treasury Department records to substantiate departures and connections to Iranian ports.

Public reaction in comment threads expressed both skepticism about intelligence and alarm over China permitting such departures.

IRISL ship anomalies and fallout

Maritime observers flagged operational anomalies.

Three reportedly diverted away from Bandar Abbas and one stopped transmissions about 13 miles out.

At least two IRISL vessels were reported en route to Gaolan, raising warnings that Iran's need for propellant precursors has become "urgent to existential" and that Chinese allowances for such shipments could strain Beijing's relations with Gulf states.

Key Takeaways

  • Two Iranian-owned ships left a Chinese chemical-storage port for Iran this week.
  • The United States accuses the ships' owner of supplying material to Iran's ballistic missile program.
  • Washington Post analysis used ship-tracking data, satellite imagery, and Treasury Department information.
