China, South Korea, and the United States are the leading exporters of phthalic anhydride, collectively accounting for over 60% of global exports in 2023–2024, while India, Germany, and Mexico represent the largest importers. Phthalic anhydride prices have remained sensitive to feedstock (naphthalene/o-xylene) volatility and regional supply-demand imbalances. Exports from China have expanded steadily amid growing downstream polyester resin demand, while European imports have declined modestly amid capacity rationalization and shifting polymer formulation preferences.
Recent Market Dynamics Intelligence
1. **Price Trends**
- The domestic market price of phthalic anhydride (PA) has generally shown narrow fluctuations. As of [Specific Date], the mainstream quotation for naphthenic-route PA in the East China region was [X1] RMB/ton, an increase of [X2] RMB/ton (a rise of [X3]%) compared to the previous week; in the North China region, the mainstream quotation was [X4] RMB/ton, a decrease of [X5] RMB/ton (a drop of [X6]%) compared to the previous week.
- The price of naphthalene-route PA remained relatively stable, with the mainstream price in the East China region at [X7] RMB/ton, essentially unchanged from the previous week.
2. **Supply Situation**
- Recently, the operations of some PA production plants have been stable, with operating rates maintained at around [X8]%. However, [Specific Quantity] enterprises have short-term maintenance plans, which are expected to reduce market supply by approximately [X9] tons.
- Regarding imports, the volume of PA imports has remained stable recently, posing minimal impact on domestic market supply.
3. **Demand Situation**
- The operating rate of the downstream unsaturated polyester resin (UPR) industry is around [X10]%, with demand for PA showing average performance. Some UPR enterprises, due to unsatisfactory order conditions, have adopted cautious procurement strategies, purchasing on an as-needed basis.
- Demand for PA from the plasticizer industry has also not seen significant improvement; enterprises have mostly maintained normal production, with no substantial changes in procurement volumes.
4. **Cost Aspects**
- The market price of orthoxylene (OX) has fluctuated slightly. As of [Specific Date], the mainstream price of orthoxylene in the East China region was [X11] RMB/ton, an increase of [X12] RMB/ton compared to the previous week. The slight rise in orthoxylene prices has provided certain support to PA costs.
- The market price of industrial naphthalene has remained stable, resulting in little change in the cost of naphthalene-route PA.
Analysis and Judgment
1. **Reasons for Price Fluctuations**
- The narrow fluctuation in naphthenic-route PA prices is mainly influenced by costs and supply expectations. The slight increase in orthoxylene prices has raised the cost of naphthenic-route PA, prompting some enterprises to raise prices; meanwhile, expectations of reduced supply due to maintenance plans of certain enterprises have also provided support to prices. However, the flat demand from downstream industries has limited the upward price potential.
- The stability of naphthalene-route PA prices is due to stable industrial naphthalene prices (no changes in the cost side) and the absence of significant fluctuations in downstream demand.
2. **Market Supply-Demand Relationship**
- The current market supply and demand are in a relatively balanced state. Although some enterprises have maintenance plans, the overall reduction in supply is limited, and stable import volumes ensure that market supply can basically meet downstream demand. Meanwhile, the average operating rates of downstream industries and sluggish demand growth have exerted little upward pressure on prices.
Forecast
1. **Price Trend Forecast**
- In the short term, naphthenic-route PA prices are expected to maintain a narrow upward trend under the support of costs and supply reduction expectations, but the increase will be limited. The mainstream price of naphthenic-route PA in the East China region is forecasted to fluctuate within the range of [X13 - X14] RMB/ton.
- Naphthalene-route PA prices will continue to remain stable, with the mainstream price in the East China region maintained around [X7] RMB/ton.
2. **Supply-Demand Trend Forecast**
- On the supply side, as maintenance periods for some enterprises conclude, market supply will gradually recover, potentially increasing supply pressure.
- On the demand side, unless there are significant positive stimuli, downstream demand is unlikely to see substantial growth and is expected to maintain its current flat state. Consequently, the overall market supply-demand relationship may gradually shift towards a surplus (supply exceeding demand).
Phthalic anhydride is a white, crystalline solid with a slight, pungent odor and moderate volatility; it melts at approximately 131 °C and sublimes readily at elevated temperatures. It is an aromatic cyclic organic compound and a key chemical intermediate in industrial organic synthesis. Its primary use is in the production of orthophthalate plasticizers—especially di(2-ethylhexyl) phthalate (DEHP) and diisononyl phthalate (DINP)—for polyvinyl chloride (PVC) applications. It is also a critical precursor for unsaturated polyester resins (UPRs), alkyd resins, and certain dyes and pigments. Major application areas include construction materials, automotive coatings, marine composites, and industrial surface finishes.
The compound is a high-tonnage chemical and is widely used in a variety of industrial organic syntheses.
Phthalic Anhydride is moderately flammable, white solid (flake) or a clear, colorless, mobile liquid (molten) Characteristic, acrid, choking odor.
This chemical is included in Basic Chemicals - Polyurethanes. See more about what is Phthalic anhydride and Phthalic anhydride SDS information.
