Industrial and specialty chemicals manufacturer Thirumalai Chemicals Ltd (TCL) step-down subsidiary TCL Specialties LLC is on track to complete and stabilise its $255-million state-of-the-art facility in West Virginia during the first half of calendar year 2026.
The US facility houses two major plants with an annual capacity of 40,000 tonnes of Maleic Anhydride (MAn) and over 30,000 tonnes of Malic Acid (MAc) and Fumaric Acid (FAc).
The company commenced the first phase of commercial operations in December 2025, marked by the first sale of MAn. Stabilisation of the remaining units is expected to be completed progressively through H1 CY26.
While adverse weather conditions during January and February 2026 caused minor disruptions, TCL said these challenges were successfully navigated and the overall schedule remains intact.
Product Portfolio and End-Use Markets
MAn is a key industrial intermediate used across housing, automotive and transport, infrastructure, energy, water treatment materials, coatings, additives and lubricants, high-performance polymers, and a wide range of specialty and functional products.
The new plant is strategically positioned to cater to customers in the North-Eastern and Mid-West regions of the US—markets that are currently underserved.
The Food Ingredients plant will manufacture Malic Acid and Fumaric Acid, both widely used in snack foods, candies, beverages, preserves, and food processing applications.
These organic acids are naturally occurring compounds in human and animal metabolic processes and play a vital role in energy conversion. Initially, the facility will serve customers across North America, LATAM and EU markets.
Market Opportunity and Competitive Landscape
TCL said that the US currently has only one domestic manufacturer of Malic and Fumaric Acid, operating at a cost disadvantage. Imports account for more than 65% of Malic Acid consumption in the US and Mexico and over 70% of Fumaric Acid demand in the US. Additionally, recent acquisitions of two major MAn producers by end users have opened up opportunities in the merchant market.
Feedstock accounts for 50–70% of production costs, and prices in the region are at least 25% lower than in other global markets. Around 40% of North American MAn customers are located within a 1,000-mile radius of the project site, offering logistical advantages.
Cost Efficiency and Future Expansion
Despite global cost escalations, TCL said the project cost remains lower than comparable plants built by global peers, aided by modular construction undertaken in India. The project is expected to achieve payback within seven years of operations.
The facility benefits from assured long-term supplies of competitively priced n-Butane and full integration, enabling self-generated energy usage and downstream value addition.
The plant has been constructed in-house, with 100% of plant and machinery manufactured at TCL’s SEZ unit in Ranipet and shipped to the US for final assembly, ensuring quality control and cost arbitrage.
The site is AI-enabled and IoT-integrated, allowing predictive maintenance, operational optimisation, and continuous performance improvement. Its location within an established industrial complex also enables seamless future expansion and diversification into downstream derivatives.
