Dioctyl Phthalate prices in Germany, the highest-cost reporting region, rose 2.0% in Q2 2026 to USD 2,030.00/MT from USD 1,990.00/MT in Q1, extending a steady climb that stands apart from the weakness seen elsewhere in this market since early 2025. South Korea posted the sharpest regional gain, up 3.3% to USD 1,260.00/MT, as the market continued its tentative recovery from a punishing 2025 decline. Globally, the average rose from USD 1,453.00/MT in Q1 to USD 1,491.50/MT in Q2, a 2.6% gain. For H2 2026, a global average of USD 1,430.00-1,600.00/MT is expected, described as a sideways-to-mild recovery rather than a sharp rebound.
Dioctyl Phthalate, commonly abbreviated DOP, is a plasticizer produced from 2-ethylhexanol and phthalic anhydride, used almost exclusively to impart flexibility to polyvinyl chloride, or PVC, in applications ranging from flooring and wire and cable insulation to automotive interior components and flexible films. As one of the most widely used general-purpose plasticizers, DOP demand tracks flexible PVC consumption closely, making construction and automotive sector activity the dominant demand driver. Phthalic anhydride and 2-ethylhexanol feedstock costs, PVC sector demand and inventory levels, and regional export discipline among major producers are what drive prices in this market.
The outlook for Dioctyl Phthalate through H2 2026 points to a sideways-to-mild recovery rather than a sharp rebound, contingent on phthalic anhydride and 2-ethylhexanol feedstock movements. Europe should continue its comparatively steady, resilient path, while Asian markets, still working through elevated inventories built up during 2025's oversupply, look likely to see only a gradual firming as PVC demand slowly improves.
The main upside risk is a faster-than-expected recovery in construction-linked PVC demand, particularly in Asia, which could accelerate the drawdown of elevated inventories built up through 2025. The main downside risk is continued high plant utilization among major Asian producers outpacing demand recovery, which would extend the current period of low, rangebound prices.
| Region | 2026 Price Range (USD/MT) | Outlook |
| Global Average | 1,430.00 - 1,600.00 | Sideways-to-mild recovery contingent on feedstock trends |
| Germany | 2,010.00 - 2,150.00 | Steady European PVC demand sustains the highest cost |
| United States | 1,630.00 - 1,760.00 | Import competition and stable supply limit further gains |
| South Korea | 1,240.00 - 1,360.00 | Export discipline supports a gradual recovery |
| China | 1,160.00 - 1,270.00 | Elevated inventories keep this the most affordable market |
German Dioctyl Phthalate prices averaged USD 2,030.00/MT in Q2 2026, the highest of any region tracked here, up 2.0% from USD 1,990.00/MT in Q1, extending a steady climb that has held since early 2025 even as other regions struggled.
Why did the price of Dioctyl Phthalate change in Q2 2026 in Germany?
Steady, if unspectacular, PVC consumption across German and broader European construction and automotive sectors, combined with stable regional supply conditions, kept this market on the same resilient upward path it has followed for over a year.
US prices averaged USD 1,660.00/MT in Q2 2026, up 2.5% from USD 1,620.00/MT in Q1, as easing import parity pressure allowed for modest gains.
Why did the price of Dioctyl Phthalate change in Q2 2026 in the United States?
Competitive Asian offers had pressured domestic cargoes earlier in the year, but as that import parity pressure eased somewhat, US producers found modest room to firm prices even amid still-cautious PVC demand.
South Korean prices averaged USD 1,260.00/MT in Q2 2026, up 3.3% from USD 1,220.00/MT in Q1, the sharpest regional gain as export discipline continued supporting a gradual recovery.
Why did the price of Dioctyl Phthalate change in Q2 2026 in South Korea?
Disciplined production among major South Korean suppliers helped mitigate the oversupply that had weighed on this market through 2025, and strong export inquiries, particularly to the United States, supported continued price stability and gradual gains.
Chinese prices averaged USD 1,185.00/MT in Q2 2026, the lowest of the four regions, up 3.0% from USD 1,150.00/MT in Q1, as elevated inventories built up during 2025 continued only slowly working their way down.
Why did the price of Dioctyl Phthalate change in Q2 2026 in China?
High plant running rates through 2025 had left the market with a substantial supply surplus, and while downstream demand from PVC producers improved modestly, elevated inventories continued to limit the pace of any recovery.
German prices rose 1.5% in Q1 2026 to USD 1,990.00/MT from USD 1,960.00/MT in Q4 2025, continuing the steady, resilient climb that has defined this market since early 2025.
Why did the price of Dioctyl Phthalate change in Q1 2026 in Germany?
Improving PVC consumption, stable regional supply, and somewhat higher input costs continued supporting the steady price gains that have set Europe apart from the rest of the global market since early 2025.
US prices rose 1.2% in Q1 2026 to USD 1,620.00/MT from USD 1,600.00/MT in Q4 2025, a modest early sign of stabilization after several quarters of decline.
Why did the price of Dioctyl Phthalate change in Q1 2026 in the United States?
Easing feedstock costs for phthalic anhydride and 2-ethylhexanol reduced cost pressure for domestic manufacturers, even as competitive Asian offers continued to weigh on the pace of any recovery.
South Korean prices rose 1.7% in Q1 2026 to USD 1,220.00/MT from USD 1,200.00/MT in Q4 2025, an early sign of recovery after a steep 2025 decline.
Why did the price of Dioctyl Phthalate change in Q1 2026 in South Korea?
Despite maintenance turnarounds at key regional facilities, disciplined production and strong export inquiries from the United States provided enough support to nudge prices higher after an extended period of oversupply-driven weakness.
Chinese prices rose 1.8% in Q1 2026 to USD 1,150.00/MT from USD 1,130.00/MT in Q4 2025, a modest rebound after a punishing period of oversupply-driven declines.
Why did the price of Dioctyl Phthalate change in Q1 2026 in China?
Seasonal downstream slowdown had reduced PVC-related procurement through much of 2025, but increasing Chinese availability combined with early signs of demand recovery began to stabilize the market heading into the new year.
Global Dioctyl Phthalate prices declined through most of 2025 on weak PVC demand, high inventories, and aggressive Asian export pricing, before finding a floor and posting modest gains in both Q1 and Q2 2026, with Germany standing apart throughout as the one consistently resilient market.
| Quarter | Price (USD/MT) | QoQ Change | Direction |
| Q2 2026 | 1,491.50 | +2.6% | ↑ Rising |

Dioctyl Phthalate had a genuinely difficult 2025 across most of the markets covered in this report, with weak PVC demand, high inventories, and aggressive export pricing from major Asian producers driving steep declines, while Germany stood out as the one region to post a positive annual gain.
German prices firmed from about USD 1,900.00/MT in Q1 2025 to USD 1,960.00/MT by Q4, a gain of roughly 3.2%, the only region among the four to post a positive annual figure, supported by steadier European PVC demand and input costs.
US prices fell from about USD 1,750.00/MT in Q1 2025 to USD 1,600.00/MT by Q4, down roughly 8.6%, as weak PVC demand and competitive Asian offers pressured the market throughout the year.
South Korean prices fell from about USD 1,450.00/MT in Q1 2025 to USD 1,200.00/MT by Q4, down roughly 17.2%, the steepest annual decline of the four regions as oversupply and weak seasonal demand weighed heavily on this market.
Chinese prices fell from about USD 1,300.00/MT in Q1 2025 to USD 1,130.00/MT by Q4, down roughly 13.1%, as high plant running rates and soft PVC demand kept this market under sustained pressure through the year.
