Kaneka Corporation (Headquarters: Minato-ku, Tokyo; President: Kazuhiko Fujii) will revise the sales price of modified silicone polymer (product names: Kaneka MS PolymerTM and SilylTM). For shipments from April 1, 2026, the current price will be raised by at least 120 JPY/ kilogram.

Due to the deterioration of the situation in the Middle East, the maritime transportation environment around the Strait of Hormuz has become increasingly unstable, resulting in serious disruptions to the supply of crude oil and petroleum products. In addition, energy-related costs have continued to rise.

While we have made substantial efforts to improve profitability through cost reductions, these measures alone are no longer sufficient. As a result, we have determined that a price adjustment is necessary to ensure a stable supply going forward.

Depending on changes in global affairs, military conditions in the Middle East, and raw material or energy markets, we may need to request further price adjustments.
