Even niche trades feel the shipping shock

The cargo getting stranded by the Iran war is not just oil. Frankincense, the tree resin burned in churches and used in perfumes and creams, is also getting stuck after shipping routes around Oman and the Gulf were disrupted in early April 2026. (upr.org) That surprised importers because frankincense moves in much smaller volumes than crude, but it still depends on the same sea lanes, the same insurers, and the same container schedules. One break in that network can freeze a niche product just as fast as a major commodity. (kuow.org) Most of the world’s frankincense comes from Boswellia trees in Oman, Yemen, and the Horn of Africa. Much of Oman’s harvest is tied to Dhofar in the south, the same region whose ancient frankincense sites are listed by the United Nations Educational, Scientific and Cultural Organization as World Heritage. (unesco.org) Those sites exist because frankincense was once valuable enough to build ports and caravan towns around it. The United Nations Educational, Scientific and Cultural Organization says the remains at Wadi Dawkah, Shisr, Khor Rori, and Al Baleed show a trade that shaped the ancient and medieval world for centuries. (unesco.org) Today the old trade runs through modern infrastructure, especially the Port of Salalah in Oman. Salalah sits beside the main east-west shipping lane and links Oman to the wider Middle East, the Indian subcontinent, and East Africa through regular container services. (asyad.om) That modern network is exactly what the war hit. International Business Times Australia reported on April 9 that traffic through the Strait of Hormuz remained restricted even after a fragile two-week United States-Iran ceasefire announced on April 8, with shippers looking for pipelines, land corridors, and long detours instead. (ibtimes.com.au) The Strait of Hormuz is a narrow passage between Iran and Oman, and even ships that do not carry oil feel the shock when that corridor becomes risky. International Business Times Australia reported that the waterway normally handles about 20 to 21 percent of the world’s oil, which means any disruption there immediately scrambles vessel availability and freight pricing across the region. (ibtimes.com.au) For a product like frankincense, rerouting is harder than it sounds. A low-volume export cannot easily charter its own ship, so it has to wait for space on larger routes that carriers may cut, delay, or reprice when insurers and crews judge the region too dangerous. (upr.org) That leaves buyers hunting for substitutes from Yemen, Somalia, or Ethiopia, even though resin quality, scent profile, and certification can vary by origin. The same NPR report said thousands of tons are exported each year from Oman, Yemen, and the nearby Horn of Africa, so shifting supply is possible in theory but messy in practice. (wuwf.org) Salalah’s own numbers show how dependent the system is on regular container flow. The port handled more than 3.19 million twenty-foot equivalent units in 2025, including 2.86 million transshipment units, which means much of its business depends on cargo being transferred smoothly from one vessel to another on tight schedules. (salalahport.com.om) When a port like that loses route reliability, the damage spreads beyond headline cargoes. A resin tapped from wild trees in Dhofar can end up delayed for the same reason as gasoline in Asia or factory parts in Europe: the ship, the slot, or the insurance vanished first.
