Mitsubishi Gas Chemical Co., Inc. has announced that its affiliate, MGC Specialty Chemicals Netherlands BV (Botlek Rotterdam, Netherlands), will temporarily suspend construction of its meta-xylenediamine (MXDA) production facility at Rotterdam, as per Chemweek.
This decision comes in response to significant construction delays, rising costs and shifts in the market environment. The facility was supposed to support growing demand in the epoxy, polyamide and isocyanate sectors, with a targeted production capacity of 25,000 metric tons per year.
The MXDA production facility was intended to establish a new production site in Europe, the largest market for MXDA, with plans to commence operations by July 2024. However, the project faced several hurdles, including a change in one of the contractors mid-construction, which contributed to delays. Additionally, the ongoing Russia-Ukraine conflict led to substantial increases in construction and labor costs, said the company.
Given these challenges, Mitsubishi Gas Chemical expressed concerns that the commercial feasibility of the project may deteriorate from its initial projections. As a result, the company decided to halt construction work temporarily to conduct a thorough review of the business plan and assess the future of the project.
The company is evaluating the impact of this suspension on its consolidated financial results for the fiscal year ending March 31, 2026. It has committed to providing timely updates if any significant developments arise that require disclosure.

Hydrazine and its derivatives are also used in the manufacture of agricultural, pharmaceutical, water treatment and industrial products.

Gottwald, NewMarket’s chairman and CEO.
NewMarket acquired American Pacific Corp. (Ampac; Cedar City, Utah), a producer of the rocket fuel ammonium perchlorate, for approximately USD700 million in 2024. In April 2025, Ampac announced plans for a USD100 million ammonium perchlorate expansion.
AE Industrial Partners acquired Calca from Arxada, a spin-off from Lonza, in 2024.
