Ise Chemical has signed an iodine extraction agreement in the US with Select Water Solutions and its wholly owned Oklahoma subsidiary, Woodward Iodine Corporation, giving the group the right to extract and commercialise iodine from Select's oilfield brine. The initial term is 10 years, extendable to as much as 20 years at Ise's option, and the company says the project is targeting about 3,000 metric tonnes of annual output by 2030.
The stated aim is to create a new US iodine supply source by using brine resources available through Select's network, in anticipation of future demand growth. Ise said that, after the contract was signed on June 25 local time, it would begin construction of a first satellite plant in Texas and then expand production bases across the US.
| Feature | What the disclosure says |
|---|---|
| Rights acquired | Ise acquires the right to extract and commercialise iodine from Select's oilfield brine in the US. |
| Initial term | 10 years |
| Extension option | Up to 20 years total, at Ise's option |
| Equipment investment | Ise bears all equipment investment costs |
| 2030 target | About 3,000 MT a year |
| Rollout plan | First satellite plant in Texas, with phased expansion centred on Texas and New Mexico |
| Current impact on results | Company says the effect is minor at this stage |
A key condition is capital. Ise said it will bear all equipment investment costs itself. Its assumptions for the rollout centre on phased satellite-plant deployment mainly in Texas and New Mexico.
The 3,000-tonne figure is not presented as a fixed schedule. Ise describes its production outlook as an estimate based on plant start-up timing, brine supply volumes, iodine concentration, recovery rates and operating rates. It also warns that permits, construction, operating conditions, market conditions and other factors could change both timing and output.
For readers outside Japan, the filing shows Ise tying part of its future production plan to US oilfield brine resources, with Texas as the first build location and New Mexico built into its assumptions. Select, which the disclosure describes as a US provider of water management and chemical solutions to the energy industry, reported $1,407mn of sales and $28mn of operating profit in 2025. Ise said the agreement's impact on its results is currently expected to be minor.
