Dioctyl Phthalate (DOP) Price Trend and Forecast

Dioctyl Phthalate Price Trend Q1 2025

DOP prices continued their downward trajectory in Q1 2025, falling by 8.65% to USD 1066/MT. The drop was largely a result of subdued industrial activity following the Spring Festival, which led to a temporary lull in demand from major end-use sectors like flexible PVC, artificial leather, and adhesives. Additionally, ongoing cost pressure from weak upstream markets and limited export interest added to the bearish tone.

Many buyers remained hesitant, adopting a wait-and-see approach amid uncertainty in both domestic policy and global trade. Despite some signs of recovery in the broader chemical sector, the DOP market remained oversupplied and under pressure. 

Dioctyl Phthalate Price Trend Q2 2025

In Q2 2025, Dioctyl Phthalate prices recorded a slight decline of 1.69%, falling to USD 1048 per metric ton. This softening was primarily driven by weak demand from downstream industries such as flexible PVC, synthetic leather, and cable manufacturing, which continued to operate at limited capacities. Although feedstock prices for phthalic anhydride and 2-ethylhexanol remained largely stable, they provided little upward pressure on finished product values.

Export interest remained flat, with most regional buyers adopting a cautious procurement strategy in light of oversupplied inventories and subdued consumption. Additionally, increased competition among domestic producers led to aggressive pricing to maintain market share, further weighing down the market.

Overall, the Chinese DOP market in Q2 was shaped by soft demand fundamentals, steady raw material costs, and a generally bearish outlook from both domestic and overseas buyers. 

Dioctyl Phthalate Price Trend Q3 2025

In the third quarter of 2025, the global Dioctyl Phthalate (DOP) market experienced a slight decrease in prices, down approximately 2-5% from the previous quarter. A decline in the costs of feedstock 2-ethylhexanol and phthalic anhydride, paired with weaker demand from key downstream sectors including PVC films, cables, and synthetic leather, led to prices moving softer.

Despite steady rates of production from key Asian and European facilities, continued high inventories and slow restocking by converters keep the general price sentiment softer. Looking to the upcoming quarter, steady prices for raw materials, alongside some gradual recovery in construction and packaging demand, will provide some moderate support to the Dioctyl Phthalate market in terms of prices.

The import market in Thailand was relatively stable, but downstream demand from PVC compounding and flexible plastic markets was weaker.

Dioctyl Phthalate Price Trend Q4 2025

Q4 2025 Dioctyl Phthalate prices in global market showed a declining trend, reflecting a relatively soft market environment across key regions. The downturn was mainly driven by easing feedstock costs, particularly phthalic anhydride and n-octanol, which reduced overall production expenses. In addition, improved logistics conditions and ample supply availability across major exporting countries ensured smooth material flow in the market.

Despite steady demand from downstream sectors, buyers remained cautious, opting for need-based procurement and engaging in extended negotiations amid expectations of further price corrections. The Dioctyl Phthalate price trend in global market highlighted these dynamics, where sufficient inventories and reduced upstream cost pressure outweighed intermittent supply chain disruptions, keeping the overall sentiment slightly bearish yet stable.

In December 2025 Dioctyl Phthalate prices in global market increased due to temporary supply tightness and firmer feedstock costs, particularly phthalic anhydride. Short-term logistics disruptions and restocking activity ahead of year-end further supported the upward movement in prices.

China: Dioctyl Phthalate Export prices FOB Shanghai, China, Grade- Industrial grade (99.0% min purity)

Dioctyl Phthalate prices in China follow a downward trajectory during the final quarter of 2025, signalling a soft market environment. This decline stems from softening feedstock expenses, specifically for 2-ethylhexanol and phthalic anhydride, which effectively lower production costs. Furthermore, the Dioctyl Phthalate price in China stays under pressure as high domestic production and efficient logistics ensure a consistent flow of materials.

Although downstream sectors maintain steady requirements, procurement remains strictly need-based as buyers anticipate further market corrections. The Dioctyl Phthalate price trend in China reflects a scenario where high inventory levels and diminished upstream costs offset minor supply chain hitches, sustaining a bearish yet stable sentiment.

In China, Dioctyl Phthalate prices in December 2025 increase by 3% because of localized supply tightness and a sudden rise in phthalic anhydride costs. Brief logistical bottlenecks and active year-end restocking efforts provide the necessary support for this short-term price appreciation.

South Korea: Dioctyl Phthalate Imported prices FOB Busan, South Korea, Grade- Industrial grade (99.5% min purity)

In Q4 2025, the Dioctyl Phthalate price in South Korea moves downward as the market carries a softer tone through the quarter. This decline mainly follows easing costs of key feedstocks such as phthalic anhydride and naphtha, which reduces pressure on producers.
