The final phase is complete
BASF inaugurated the MDI expansion at its Geismar, Louisiana, site on November 11. The company puts the three-phase project’s investment at approximately $1 billion and annual site capacity at about 600,000 metric tonnes, almost twice the previous level. Its project page confirms startup of the third and final phase.
Who the additional capacity serves
MDI is used to make polyurethanes for industries including construction, appliances, transport, footwear and furniture. BASF says the project also expands aniline production, supporting its integrated manufacturing chain and additional North American supply.
Capacity is not an earnings result
The project began in 2018, with earlier units commissioned or expanded in 2020 and 2021. The November 11 event marks final-phase completion, rather than a newly announced future build. The stated capacity is not measured annual output, utilization, customer deliveries or booked revenue. No product-price reduction or investment return follows automatically from the expansion.
