Cost Decline and Supply Increase Lead to Fluctuating Price Drop in DOP in August

ECHEMI 2025-08-13

August 12th, news:

In August, the price of plasticizer DOP in China fluctuated and fell.

According to the commodity market analysis system, as of August 12, the DOP price was 7809.16 CNY/ton, a 1.84% decrease from the DOP price of 7955.83 CNY/ton on August 1. In August, DOP production increased to 66% of capacity, leading to an increase in plasticizer output and a decline in plasticizer prices. Downstream demand remains weak, with little interest in DOP procurement inquiries. The prices of raw materials, such as 2-ethylhexanol and phthalic anhydride, have also declined, reducing cost support for plasticizers. With reduced supply and lower costs, plasticizer prices continue to fall.

August raw material isooctanol prices fluctuated and declined in China

According to the commodity market analysis system, as of August 12, the price of 2-ethylhexanol was 7,383.33 CNY/ton, a fluctuating decline from the price of 7,533.33 CNY/ton on August 1, with a price decrease of 1.99%. In August, the price of 2-ethylhexanol has been fluctuating downward, leading to a reduction in plasticizer costs and increasing the pressure for DOP prices to fall.

August raw material phthalic anhydride prices fluctuated and declined in China

According to the commodity market analysis system, as of August 12, the price of ortho-phthalic anhydride in China was 6533.33 CNY/ton, a 1.75% decrease from the price of 6650 CNY/ton on August 1. On August 12, the price of ortho-xylene in China was 6500 CNY/ton, a 4.41% decrease from the beginning of the month. The cost of phthalic anhydride has decreased, and there has been an increase in maintenance of phthalic anhydride equipment in August, leading to a slight decline in the operating rate of phthalic anhydride enterprises. However, the supply of phthalic anhydride remains sufficient. The operating load of plasticizer enterprises downstream has increased, providing continued support for the demand for phthalic anhydride. With the reduction in costs, the price of phthalic anhydride in August has fluctuated and declined.

Future Market Expectations

The plasticizer product data analyst believes that, in terms of cost, prices of isooctanol and phthalic anhydride have fluctuated downward, leading to a decrease in the cost of plasticizer DOP. In terms of supply, plasticizer enterprises have resumed operations, increasing production and overall supply. However, demand remains weak due to factors such as the sluggish overall economy, intensified competition (anti-involution), and elimination of outdated production capacity. Overall, with increased supply and decreasing costs, coupled with persistently weak demand, it is expected that the price of plasticizer DOP will continue to fluctuate downward in the future.
