Recently, the Department of Ecology and Environment of Ningxia Hui Autonomous Region officially issued a public notice, accepting the environmental impact assessment report for the 100,000 tons/year HDI and 180,000 tons/year phosgene expansion and renovation project (Phase I) of Ningxia Ruitai Technology Co., Ltd. This marks a critical milestone in the preliminary approval process for this high-end chemical new materials project. According to the disclosed environmental assessment documents, the overall planned scale of the project is substantial. Upon completion, it will achieve an annual production capacity of 100,000 tons of HDI, 100,000 tons of HDI trimer, and 180,000 tons of phosgene, with a by-product of 290,000 tons/year of 30% hydrochloric acid. The project will be implemented in phases, with the current environmental assessment acceptance stage focusing on Phase I. The core objective of this phase is to expand the existing phosgene production capacity from 30,000 tons/year to 50,000 tons/year, laying the raw material foundation for the subsequent construction of the main facilities.

Key Project Information Overview

• Project Owner: Ningxia Ruitai Technology Co., Ltd.
• Project Nature: Expansion, to be carried out within the existing plant site with no additional land acquisition.
• Location: Fine Chemical Zone, Zhongwei Industrial Park, Ningxia.
• Investment: Total estimated investment is 9.743 million yuan, with environmental protection investment accounting for 610,000 yuan, representing 6.26% of the total.
• Compliance Approvals: The project has obtained the enterprise investment project filing certificate and received approval from the National Office for the Prohibition of Chemical Weapons, agreeing to expand the phosgene production facility capacity from 30,000 tons/year to 180,000 tons/year, in compliance with national monitoring chemical management requirements.

HDI (hexamethylene diisocyanate) is a core raw material in the high-end polyurethane sector, widely used in automotive coatings, industrial corrosion protection, aerospace, and other high-end applications. It is a specialty chemical with high technical barriers. The large-scale expansion by Ruitai Technology will further enhance the domestic high-end isocyanate industry layout and strengthen the self-reliance and controllability of the local supply chain.
