Asia

HDI prices in the Asia-Pacific region showed a mixed trend throughout the first half of 2025. In Q1, prices rose in January due to steady production and better feedstock supply. However, weak demand in automotive and construction, especially in China, led to a price drop in February.

After the Lunar New Year, stockpiles increased, keeping prices under pressure. In Q2, demand remained moderate in Southeast Asia, but China’s sluggish recovery and subdued property sector kept overall consumption low. Supply remained stable, but market sentiment stayed cautious due to inconsistent end-use sector performance.

Europe

In Europe, HDI prices were highly volatile in H1’25. Q1 began with a price surge due to limited raw material availability, geopolitical risks, and weather-related energy strain. But mid-quarter saw sharp declines as labor strikes, port congestion, and external trade tensions disrupted logistics.

In March, recovery began as production stabilized and demand from the automotive sector, especially EVs, picked up. In Q2, strong downstream demand from polyurethane applications in construction and automotive helped prices rebound further. However, supply chain issues, including port delays and rerouted shipments, kept supply tight and contributed to firm pricing.

North America

North American HDI prices showed a generally bullish trend in H1’25. Q1 faced weather-related production issues and shipping delays, but strong demand from automotive and construction industries supported pricing. In Q2, consistent offtakes and growing interest in electric vehicles continued to push demand. Although feedstock costs were relatively stable, freight and operational challenges added to the pricing pressure, keeping the market firm.

Hexamethylene Diisocyanate Production Processes

  • Hexamethylene Diisocyanate Production from HMDA & Chlorine

Hexamethylenediamine (HMDA) and chlorine are used to make hexamethylene diisocyanate. Chlorine and carbon monoxide react to produce phosphogene. The acquired phosgene is reacted with HMDA, and HDI is generated as a by-product with hydrogen chloride.

Frequently Asked Questions

The current HDI outlook points to broadly stable prices in the near term, with recovery contingent on stronger demand from construction, automotive, and coatings sectors across those key regions. Subdued downstream activity, cautious buyer behaviour, and oversupply in related chemical chains have kept sentiment soft in Asia, Europe, and North America. Improved feedstock availability has helped producers manage costs, but weak buying interest has prevented any meaningful price gains. A sustained upturn would require firmer end-market consumption and tighter supply management from producers.

HDI prices are shaped by weak downstream demand across coatings, construction, and automotive sectors in key regions, which suppresses buying interest and limits price gains. Oversupply can persist when producers continue operating plants despite modest demand, creating competitive pressure. Improved upstream raw material availability helps control production costs, but this relief does not always translate into price support. In Europe, seasonal summer slowdowns and trade challenges can further restrict movement, while in North America, lean buyer inventories and delayed purchase decisions compound the soft trend.

The major HDI producers are Covestro AG, Wanhua Chemical Group, Vencorex S.A.S., Asahi Kasei Corporation, and BASF SE, with Tosoh Corporation, Lanxess AG, and Mitsui Chemicals among other suppliers. Production is concentrated among a small number of manufacturers, creating meaningful supply concentration risk. Consumption spans North America, Europe, and Asia Pacific, where coatings, construction, and automotive sectors drive demand. Strict phosgene regulations further constrain supply flexibility.

HDI is produced by reacting hexamethylenediamine (HMDA) with phosgene, made from chlorine and carbon monoxide. HMDA derives from petroleum-based feedstocks including benzene, formaldehyde, cyclohexane, and adipic acid, while phosgene pricing is sensitive to chlorine and carbon monoxide costs. An alternative route uses HMDA with urea, alcohol, or carbonate. Finished HDI is consumed as a polyurethane polymerizing agent in marine and aerospace coatings, a hardener in automotive and aircraft enamels, and in dental materials, medical devices, plastics, synthetic rubber, adhesives, wire insulation, and rocket fuel binders.

HDI demand is driven primarily by the paints and coatings, automotive, aerospace, construction, and adhesives industries, where it acts as a polymerizing agent and hardener in polyurethane and enamel coatings. Soft activity in construction and automotive tends to suppress buying interest across Asia, Europe, and North America, keeping prices muted even when feedstock costs are well controlled. Recovery in any of these sectors would tighten spot availability and support firmer pricing.

Procurement Resource assesses hexamethylene diisocyanate prices through a structured, data-driven methodology that combines primary engagement with producers, suppliers and traders, secondary market data, continuous monitoring of feedstock and input costs, trade-flow and inventory tracking, and exchange or spot benchmarks. These inputs are validated and translated into a transparent price assessment and outlook. The detailed methodology is available on the Procurement Resource website.
