Unexpected production failure at BASF India's Dahej MDI plant; capacity constrained

On June 1, 2026, according to industry media sources, global chemical giant BASF's MDI (diphenylmethane diisocyanate) separator production unit in Dahej, Gujarat, India, experienced an unplanned production issue. The operation of the facility was directly impacted, and this supporting unit with an annual capacity of 50,000 tons temporarily entered a state of production disruption. Currently, BASF has not disclosed the specific cause of the failure, the duration of the shutdown, or a timeline for resuming production.

Public records show that the unit experiencing this production problem is BASF's core MDI separator production facility in the Indian market. Located in the Dahej chemical industrial park in Gujarat, a major industrial hub in India, the region is an important cluster for fine chemicals and polyurethane raw materials, featuring a complete industrial chain that supplies markets in South Asia, the Middle East, and Southeast Asia.

The unit's MDI separation capacity of 50,000 tons/year is a key component of BASF's South Asian MDI supply system. It primarily handles the purification, packaging, and supply assurance of MDI products in the region, supporting the raw material supply for downstream industries such as polyurethanes, construction materials, home appliances, and coatings.

As a core basic raw material for the polyurethane industry, MDI is often known as "chemical gold." It is widely used in thermal insulation materials, smart home furnishings, automotive interiors, synthetic leather, adhesives, and other fields. It is a key intermediate in the chemical industry chain connecting upstream basic chemicals with downstream manufacturing. The global supply and demand pattern is highly concentrated, with companies like BASF, Covestro, and Huntsman being the core global suppliers. Therefore, fluctuations in production capacity significantly impact regional and even global supply chains.

This failure is an unplanned sudden production issue, distinct from planned shutdowns such as routine annual maintenance or regular equipment servicing, and is characterized by its suddenness and uncertainty. Compared to controllable planned maintenance, sudden equipment and production failures are often difficult to predict in terms of resumption time, and can easily disrupt production schedules, spot supply rhythms, and regional market supply and demand balance. As of now, BASF has not announced the progress of the failure investigation, whether a force majeure declaration has been initiated, or released any relevant notices regarding supply adjustments.

Viewed against the backdrop of the current global MDI market, the overall market has recently been in a state of tight supply and rising prices.

Since late May, several leading international MDI companies, including BASF, Covestro, and Huntsman, have collectively issued price increase notices. Among them, BASF raised prices for its entire Lupranate® series of MDI products on May 29, with a single increase of $0.35 per pound, the highest increase in the industry during that period. At the same time, overlapping with maintenance and capacity adjustment plans for multiple overseas MDI units, BASF will also commence a 45-day shutdown for maintenance of overseas facilities in July, further exacerbating market expectations of tightening global MDI supply.

Industry analysts indicate that the sudden production disruption at BASF's Dahej facility in India will further tighten spot MDI supplies in the South Asian region. With stable demand from downstream manufacturing industries in India and the surrounding Southeast Asia and Middle East regions, this regional capacity restriction, on top of an already tight global supply, will likely exacerbate tensions in the short-term spot market and support regional MDI spot prices. If the troubleshooting cycle for the unit is prolonged and the resumption of production is delayed, it is not ruled out that this could drive fluctuations in local Asian MDI market prices.

Currently, industry organizations are continuously tracking the progress of the failure handling and production resumption. The market is largely awaiting official follow-up announcements from BASF. The subsequent progress of the unit's resumption and BASF's supply allocation plans will become key factors affecting the recent supply, demand, and price trends in the Asian MDI market. Overall, with frequent fluctuations in global MDI industry capacity and the normalization of sudden issues at regional facilities, the global MDI supply chain is expected to remain tight in the second half of the year, and market volatility risks persist.
