Polymeric MDI Price Trend Q1 2026

During the first quarter of 2026, the downward trend in prices for the global market for the polymeric MDI has continued as a result of lower feedstock prices for both benzene and aniline, along with sufficient levels to meet global demand. There has been improved production rates and normal operating conditions to provide adequate quantities of material available to the market; this allowed for minimal disruption to the overall balance of the market due to periodic logistical and supply chain issues.

As a result, end-user purchasing has been cautious, with the majority of buyers remaining engaged in negotiating price and avoiding large quantity purchases based upon expectations of further price reductions. Although Polymeric MDI pricing on a quarter-over-quarter basis has increased in the first quarter of 2026 versus the fourth quarter of 2025, supply issues and global supply disruptions have created temporary tightness in the market.

As of March 2026, due to disruptions in supply chain logistics caused by the Iran-USA war; this has significantly limited trade flow, creating logistical issues and tighter availability resulting in cost increases and general market uncertainty.

According to PriceWatch, In Q2 2025, MDI price trend in the Chinese market registered a sharp decline of 12.91%, falling to USD 2030 per metric ton. The significant drop was driven by persistent weakness in downstream sectors such as construction, insulation, and automotive manufacturing, where demand remained sluggish despite the onset of peak seasonal activity.

Additionally, oversupply in the domestic market due to high operating rates and reduced export volumes created competitive pressure among suppliers, pushing prices downward. Although feedstock prices for aniline and nitrobenzene remained relatively steady, they did not provide sufficient cost support to stabilize MDI prices.

Exporters also lowered offers to clear inventories amid weak international demand, particularly from South Asia and Southeast Asia. The overall sentiment in the Chinese MDI market remained bearish throughout Q2, with ample availability, muted downstream recovery, and limited cost push leading to steep price corrections. 

According to PriceWatch in Q2 2025, MDI prices in the Indian market saw a notable decline, with CIF prices for South Korean-origin material falling by 9.66% to USD 1935 per metric ton, while Ex domestic prices dropped more sharply by 12.39%, reaching USD 2060 per metric ton. The decline was primarily attributed to weak demand from key downstream sectors such as construction, adhesives, and refrigeration, which continued to operate at subdued levels.

The correction in global prices, especially from China and South Korea, directly impacted import costs, prompting local distributors to reduce their prices in tandem. Buyers remained highly cautious, procuring only on a need-based basis due to expectations of further price reductions and sufficient availability in the market. Freight rates remained largely stable, offering little resistance to the downward momentum.

Overall, the Indian MDI market in Q2 reflected a bearish tone driven by soft regional demand, competitive import offers, and a globally declining price environment. 

MDI prices corrected slightly in Q1 2025, falling by 1.69% to USD 2331/MT. This modest decline was attributed to typical post-holiday lulls in industrial activity following the Chinese New Year. Downstream demand from insulation and elastomer sectors softened temporarily, while some buyers delayed restocking in anticipation of further price corrections.

On the supply front, improved plant utilization and lower feedstock costs especially for benzene reduced production expenses, allowing suppliers to ease prices slightly. Despite the dip, the overall sentiment remained stable, with expectations of a rebound in Q2 as construction and manufacturing sectors regain momentum. 

MDI prices saw a modest decline in Q1 2025, with India Ex prices falling by 0.85% to USD 2351.23/MT, and CIF South Korea prices easing by 1.57% to USD 2142/MT. The downward shift was a result of typical post-holiday demand slowdown and financial year-end hesitancy across industrial buyers. Sectors like construction and foam insulation reduced offtake due to regional election-related activity, Holi-related shutdowns, and fiscal caution.

Meanwhile, improved availability from South Korea and softening feedstock prices helped lower the cost of imports. As a result, both domestic and import market participants adjusted prices to reflect subdued buying sentiment, leading to a marginal dip in overall market levels. 

Methylene Diphenyl Diisocyanate (MDI) Price Trend Analysis: Q4 2024

Prices continued to climb in Q4 2024, rising by 3.36% to USD 2371/MT, supported by sustained demand from infrastructure and appliance manufacturing sectors. While some seasonal softness typically occurs in this quarter, government-backed construction and green building initiatives helped sustain procurement from the rigid foam segment.

Meanwhile, reduced production output due to selective plant turnarounds and tighter environmental regulations in key regions added to supply-side constraints. Continued strength in overseas orders also absorbed a portion of local production, maintaining firm pricing levels despite year-end slowdowns in some domestic markets. 

Prices corrected downward in Q4 2024, with India Ex prices falling by 6.62% to USD 2371.38/MT and CIF South Korea prices dipping marginally by 0.28% to USD 2176.23/MT. The decline followed an aggressive price rally in the previous quarter and coincided with seasonal demand softening, especially as construction activity began to slow heading into winter.

Additionally, inventories had built up during the previous high-demand phase, leading to a more cautious procurement approach by downstream buyers. Imports remained steady, but competitive overseas pricing pressured domestic producers to adjust offers downward, contributing to the correction in Ex-Works values. 

In Q3 2024, MDI prices saw another rise of 3.15%, reaching USD 2294/MT. The upward trend was supported by ongoing construction and manufacturing demand, particularly in urban development projects and appliance insulation. Fluctuations in feedstock prices, particularly in the benzene market, led to an increase in overall production costs.

At the same time, limited new supply and low stock levels across many downstream converters allowed suppliers to maintain pricing discipline. Export activity remained healthy, especially to South Asia and the Middle East, further tightening domestic availability and keeping the market on a positive trajectory. 

In Q3 2024, MDI prices saw their most significant quarterly rise, with India Ex prices jumping 10.54% to USD 2539.54/MT, while CIF prices rose by 4.94% to USD 2182.31/MT. The sharp increase in domestic prices was primarily driven by peak-season construction activity, particularly in commercial insulation and infrastructure expansion projects.

Delays in cargo arrivals from South Korea due to port congestion and weather disruptions also limited import availability, pushing more buyers to rely on domestic sources. Additionally, a brief supply squeeze from a key Indian producer undergoing unplanned maintenance added to the price hike. Despite the rise in CIF values, the local market continued to command a premium due to tight supply and high demand. 

MDI prices rose further by 4.02% in Q2 2024, settling at USD 2224/MT. The increase was supported by improved construction activity as warmer weather spurred demand for rigid foam applications in insulation and paneling. Rising feedstock costs and tightening logistics in select regions added to upward pricing pressure.

Several manufacturers also announced scheduled maintenance, slightly limiting domestic output and adding to the bullish tone. In addition, sustained export interest and moderate inventory levels encouraged producers to hold firm on pricing, leading to a gradually strengthening market throughout the quarter. 

Prices continued their upward trajectory in Q2 2024, with India Ex rising by 5.01% to USD 2297.46/MT and CIF values increasing by 6.47% to USD 2079.54/MT. The rise was supported by strong demand from the construction and appliance manufacturing sectors, fueled by summer-driven installation of insulation and refrigeration units.

Tightened vessel availability and extended lead times on South Korean shipments contributed to firmer CIF values. Domestically, producers faced elevated raw material costs, particularly for benzene derivatives, while robust consumption kept inventories low. This favorable demand-supply dynamic allowed both local suppliers and importers to maintain pricing strength. 

Prices increased by 4.19%, reaching USD 2138/MT in Q1 2024. The uptick was driven by a combination of rising feedstock costs—particularly aniline and benzene—and moderate post-Lunar New Year restocking activity. Downstream manufacturers resumed production across sectors such as insulation, adhesives, and polyurethane elastomers, contributing to increased demand.

Although domestic consumption was slightly staggered due to the extended holiday period, robust export orders helped absorb supply. Producers leveraged tighter supply in the early part of the quarter, supporting firmer pricing as inventories remained manageable. 

MDI prices rose in Q1 2024, with India Ex prices increasing by 4.02% to USD 2187.8/MT and CIF prices from South Korea rising by 9.09% to USD 1953.08/MT. The surge was driven by strong post-winter restocking demand and heightened activity in insulation and cold storage sectors. Supply disruptions in parts of Northeast Asia, due to planned maintenance and tighter regulations, limited availability of imports, pushing CIF prices higher.
