Asia
In China, the average price of DOP (Dioctyl Phthalate) was ~USD 1,426/MT in May and fell to ~USD 1,338/MT in June, a ~6% decrease. Earlier in the year, the market received strong cost support as the Strait of Hormuz disruption sharply reduced Middle Eastern naphtha availability. Middle Eastern naphtha exports fell to 692,000 tonnes in March from 4.06 million tonnes in February, while pre-conflict flows had supplied roughly 60–70% of Asia’s import requirements. Cracker disruptions in Singapore and South Korea further tightened propylene availability for the 2-ethylhexanol chain. However, the subsequent reopening of Hormuz and lower crude costs weakened feedstock support. In India, DOP prices were ~5% lower in June, moving from ~USD 1,493/MT in May to ~USD 1,426/MT.
Europe
Germany recorded an average DOP (Dioctyl Phthalate) price of ~USD 1,519/MT in May, declining to ~USD 1,460/MT in June, a ~4% decrease. European DOP followed the broader crude, naphtha and aromatics cost cycle during H1. The March supply disruption tightened feedstock availability as European naphtha-fed crackers competed for alternative supply amid the disruption to Middle Eastern flows. As crude-related cost pressure eased later in the period, support for DOP weakened. At the same time, established regulatory restrictions on DEHP in Europe continued to limit its use in plasticiser applications, keeping underlying demand structurally constrained.
North America
North American DOP remained a structurally smaller market, with regulatory developments weighing on its commercial outlook. The US EPA’s final TSCA risk evaluation identified DEHP as presenting unreasonable risk under specified conditions of use, increasing pressure on applications using the substance. Demand has increasingly shifted toward alternatives such as DINP and DOTP, limiting the addressable market for DOP. Consequently, regional price direction remained more closely linked to global feedstock costs than to strong downstream consumption.
Analyst Insight
According to Procurement Resource, DOP is likely to remain sensitive to crude, naphtha and aromatics movements, while subdued downstream consumption may limit sustained upward momentum.

Asia
During the second half of 2025, the Asian DOP market experienced a continuous decline. Oversupply and weak demand from PVC users kept pressure on prices. Production at several plants remained high, while raw materials like isooctanol and phthalic anhydride saw falling costs, reducing cost support. Construction activity slowed in many countries, making buyers cautious and limiting large purchases. India, China, and South Korea all followed this downtrend, as domestic demand remained soft and exports did not pick up significantly. Overall, Asian markets faced a bearish tone throughout the period.
Europe
In Europe, DOP prices were mostly stable to slightly soft. The market faced similar challenges as Asia, including weak demand from construction and automotive sectors. European producers dealt with competition from low cost imports from Turkey and Asia, which limited opportunities to raise prices. Some specialty plasticizers maintained stable demand, but overall buying was cautious. Many buyers focused on short-term procurement rather than stocking, keeping trading activity light.
North America
North American DOP prices were steadier compared to Asia and Europe. While construction demand was subdued, domestic production was balanced with consumption, helping prevent large price drops. Imports were affected by tariffs, giving local producers some support. Certain specialty grades used in wiring, data centres, and green energy projects saw consistent demand, helping stabilize overall prices despite soft conditions.
In appearance, DOP or Dioctyl phthalate is a clear liquid with a mild odour. It is slightly less dense than water and immiscible in it. Its flash point is around 430°F. It is basically utilised in the production of a variety of plastics and coating products. It helps to keep plastics soft and flexible, for instance, it is utilised to produce plastics which are further used as medical tubing and blood storage bags, cables and wire, carpetback coating, etc.

DOP (Dioctyl phthalate) is prepared at atmospheric pressure or in a vacuum by heating an excess of n-octanol with phthalic anhydride using an esterification catalyst like sulphuric acid or p-toluenesulphonic acid. Thus, esterification of n-octanol with phthalic anhydride in the presence of a catalyst gives DOP.
