    Ube to close ammonia production

    Ube Corporation has accelerated closure plans for its nitrogen products in Asia as part of its Vision 2030 plan. The company says that it aims to halt ammonia and related product production at its Ube City plant in Japan by March 2028, two years ahead of its previous schedule. Production of caprolactam and polyamide materials at the same plant will end by March 2027. Post-restructuring, the facility will prioritize specialty chemicals such as polyimides, separation membranes, ceramics, pharmaceuticals, and high-purity chemicals.

    In Thailand, Ube will stop producing cyclohexanone, caprolactam, and ammonium sulphate, shutting down one of its two polyamide production lines. The site will shift focus to composite materials, polycarbonate diols, and elastomers, while Ube Fine Chemicals Asia will cease producing 1,6-hexanediol and 1,5-pentanediol.

    Price Trends

    Ammonia values have continued to ease across most regions at the end of June, as the first ammonia vessels begin to exit the Gulf since the Iranian conflict began. Iranian ammonia had also begun to flow to India following the US Treasury’s issuance of a 60-day sanctions waiver on 22 June, allowing dollar-denominated trade in Iranian petrochemical products through 21 August. As a result, Indian bids have been heard as low as $750/t c.fr, as buyers benefit from a widening pool of available supply - Iranian, Chinese and renewed Southeast Asian material are all competing for the same business.
