Improving feedstock availability, Chinese production restarts, and easing Middle Eastern supply concerns have combined to pull Butanediol prices lower in the third week of May 2026, though values remain elevated against prior months amid lingering Strait of Hormuz uncertainty.
After steep rises in April 2026, global Butanediol prices stayed largely steady and then declined during the third week of May. Better availability in China and Taiwan mainly explained the slide, as larger crude inflows from Middle Eastern nations kept refineries running smoothly and improved access to feedstocks.
Higher operating output at Chinese manufacturing plants and a loosening of earlier shortages across Asian markets added further downward pressure on pricing. Even so, values remained high versus prior months, reflecting earlier disruptions and resilient conditions around the Strait of Hormuz.
China: Production Restarts Drive FOB Price Decline
China’s FOB Butanediol prices recorded a significant decline during the third week of May 2026, following the sharp upward momentum witnessed in April 2026, primarily due to improving market supply fundamentals.
After completing maintenance overhauls, multiple local producers brought units back online, while output also recovered through catalyst changeouts and plant restarts.
Although some sites remained offline for maintenance, higher operating rates at other facilities largely offset those outages, leading to a modest month-to-month increase in total utilization.
As a result, import pricing across most destination markets also declined, tracking the softer FOB China market direction. However, India’s import costs increased due to higher freight charges and stable downstream demand from the THF and spandex industries.
Taiwan: Easing Middle East Supply Concerns Pull Prices Off Peak
Taiwan’s Butanediol prices recorded a significant decline during the third week of May 2026 after reaching peak levels earlier in the month, mainly due to improved supply availability from the Middle East and easing regional supply concerns.
Increased arrivals of imported material pressured FOB trends lower, consequently weighing on prices across major importing countries. However, India’s import prices remained at peak levels amid elevated freight costs and firm downstream demand.
What Comes Next
If crude oil prices continue to decline and the geopolitical situation remains stable, cost pressure in the Butanediol market is expected to ease over the coming months.
Lower prices for key feedstocks such as acetylene, butane, methanol, and formaldehyde may help manufacturers reduce overall production costs.
Alongside improving supply conditions and stable plant operating rates, the weaker raw material trend is expected to support further downward movement in global Butanediol prices.
