Strait of Hormuz Vessel Verification and Insoluble Sulfur Price Hikes

## Hormuz Vessel Verification Suggested by AIS Tracks According to gCaptain, AIS tracking data indicates that Iran may be verifying ships before allowing them to exit the Strait of Hormuz. The data shows multiple vessels passing between Iran's Larak and Qeshm islands before transiting the strait, suggesting they are undergoing some form of verification process. This comes amid ongoing tensions in the region and increased scrutiny of commercial shipping movements through the critical chokepoint. The Strait of Hormuz is a strategically important waterway, with around a fifth of the world's oil supply passing through it. Any disruptions to traffic could have significant impacts on global energy markets. ## Insoluble Sulfur Price Hikes Announced In separate news, chemical manufacturer Flexsys has announced regional price increases for its insoluble sulfur products, effective March 23, 2026. The increases are as follows: - Asia: $0.60/kg - Europe: €0.45/kg - North America: $0.40/kg - Latin America: $0.40/kg Insoluble sulfur is a key ingredient used in the production of rubber and other industrial materials. The price hikes reflect ongoing supply chain pressures and rising production costs in the chemicals sector. These developments underscore the complex operational and market dynamics impacting the global maritime industry. Shipowners, cargo owners, and other stakeholders will need to closely monitor these types of regulatory and commercial shifts to maintain efficient and cost-effective supply chains.
