Di-N-Octyl Phthalate Market share- How big is the Di-N-Octyl Phthalate market?

China and Germany are the leading exporters of Di-N-Octyl Phthalate (CAS 117-84-0), collectively accounting for over half of global export value in 2023–2024, while the United States, India, and South Korea represent the largest importers. Di-N-Octyl Phthalate prices have remained relatively stable amid steady demand from plasticizer applications in PVC production. Export volumes from China increased modestly year-on-year through 2024, while EU-based exports—led by Germany—showed slight contraction, reflecting ongoing regulatory scrutiny and substitution trends in certain end uses.

Di-N-Octyl Phthalate Market Analysis

Recent Market Dynamics Intelligence

1. Price Trends
- Over the past week, the market price of Di(2-ethylhexyl) phthalate (DOP) has shown a slight upward fluctuation. The mainstream transaction price in the East China region rose from 8,200-8,300 yuan/ton to 8,350-8,450 yuan/ton; in the South China region, it increased from 8,250-8,350 yuan/ton to 8,400-8,500 yuan/ton; and in the North China region, it climbed from 8,150-8,250 yuan/ton to 8,300-8,400 yuan/ton.

2. Supply Situation
- Recently, the operational status of some DOP production facilities has remained stable, with operating rates maintained at approximately 75%-80%. However, a few enterprises have seen a decrease in output due to equipment maintenance or raw material supply issues, leading to a slight reduction in overall market supply.
- Regarding new production capacity, there are no reports of new DOP facilities coming online, so the market supply structure is expected to remain largely unchanged in the short term.

3. Demand Situation
- Demand in the downstream plastic products industry has shown signs of recovery, particularly in the PVC soft products sector, where procurement volumes of DOP have increased. With the warming weather, an increase in outdoor construction projects has boosted demand for PVC pipes and profiles, thereby driving up DOP demand.
- Demand in the rubber products industry remains stable, with no significant changes in DOP procurement volumes.

4. Raw Material Market
- The price of the main raw material, n-octanol, has recently shown an upward trend. In the East China region, the price of n-octanol rose from 8,000-8,100 yuan/ton to 8,200-8,300 yuan/ton, strengthening cost support.
- The price of the other raw material, phthalic anhydride, has remained relatively stable, fluctuating between 7,000-7,100 yuan/ton, with a minimal impact on DOP costs.

5. Market Sentiment
- Traders and producers hold a relatively optimistic outlook for the future, believing that with increased demand and rising costs, DOP prices have room for further increases. Consequently, their willingness to maintain high prices is strong.
- Downstream users have some resistance to price increases but continue to purchase according to their production needs.

Analysis and Judgment

1. Cost-Driven Factors: The rise in n-octanol prices has increased DOP production costs. To maintain profit margins, enterprises have a willingness to raise prices, which is one of the main factors behind the recent increase in DOP prices.
2. Demand-Driven Factors: The recovery in demand in the downstream plastic products industry, particularly the increased procurement of DOP in the PVC soft products sector, has provided strong support for market prices.
3. Supply Impact: The reduction in output by some enterprises has led to a slight decrease in market supply, intensifying the tight supply-demand situation to some extent and pushing prices higher.

Forecast

1. Short-Term Forecast: It is expected that DOP market prices will continue to show a slight upward trend over the next week. The mainstream transaction prices in the East China, South China, and North China regions are expected to rise to 8,500-8,600 yuan/ton, 8,550-8,650 yuan/ton, and 8,450-8,550 yuan/ton, respectively.
2. Medium-Term Forecast: If demand in the downstream plastic products industry continues to improve and n-octanol prices remain at high levels, DOP market prices are expected to remain at a high level over the next month, although the rate of increase may gradually narrow.
3. Long-Term Forecast: In the long term, the trend of DOP market prices will depend on raw material prices, changes in downstream demand, and the introduction of new production capacity. If raw material prices drop significantly or downstream demand falls short of expectations, DOP prices may experience a correction. Conversely, if supply remains tight, prices are expected to continue rising.

About Di-N-Octyl Phthalate

Di-N-Octyl phthalate (DNOP) is a colorless to pale yellow, oily liquid with low volatility and a faint, characteristic odor. It is an aromatic ester, specifically a dialkyl phthalate, synthesized from phthalic anhydride and n-octanol. DNOP is primarily used as a plasticizer for polyvinyl chloride (PVC) and other polymers, imparting flexibility, durability, and low-temperature performance. Its main application areas include wire and cable insulation, flooring, automotive interiors, and industrial hoses—particularly where enhanced migration resistance and processing stability are required. It is also employed as a solvent and processing aid in coatings, adhesives, and sealants.

Dioctyl phthalate is used as a plasticizer in various plastic materials.
