SunSirs: Paraxylene (PX): Middle East Tensions Impact Costs; Plant Maintenance Tightens Supply

Geopolitical conflicts in the Middle East have recently caused repeated fluctuations in the international crude oil market. Coupled with concentrated maintenance shutdowns of multiple domestic PX plants—leading to a decline in the industry's overall operating rate—the market is characterized by cost volatility, tightening supply, and a recovery in demand. Amidst news of gradually resuming international shipping and production adjustments by oil-producing nations, there is currently no widespread shortage of global PX supplies, though the pace of regional circulation has slowed. This report analyzes current market dynamics and forecasts future trends by examining spot prices, production and inventory levels, import/export data, and supply chain interdependencies.

I. Domestic Regional Spot Prices (as of June 9)

As of June 9, the benchmark price for PX of SunSirs stood at 8,960 RMB/ton; in the short term, prices have tracked crude oil fluctuations, remaining within a specific range. Regionally, East China—a core hub for PX production, sales, and distribution—saw mainstream spot transactions ranging from 8,920 to 9,010 RMB/ton; market supply was tight, and traders showed a strong inclination to hold firm on prices. South China, leveraging local refining capacity, saw quotes slightly lower than in East China, ranging from 8,890 to 8,980 RMB/ton. Markets in North China and the interior relied largely on inter-regional shipments, resulting in higher landed costs and slightly elevated transaction prices; regional price differentials remained within the 30–60 RMB/ton range. Current market activity is driven primarily by essential demand, with little speculative stockpiling; prices are constrained by both raw material costs and supply-demand dynamics, limiting the magnitude of fluctuations.

II. Domestic Production, Port Inventories, and Supply Status

On the supply side, domestic PX plants have entered a period of concentrated maintenance, causing the industry's aggregate operating load to drop by 4 percentage points month-on-month. Large-scale refining units across various regions have shut down for maintenance, temporarily removing some capacity from the market and causing a short-term contraction in total industry output. The maintenance cycle spans from early June to early July, and this periodic reduction in volume is exerting significant downward pressure on spot supplies. Regarding inventory, PX stocks at major domestic ports remain at moderate levels. Previously stocked supplies are circulating steadily; however, due to plant maintenance, there is insufficient growth in subsequent arrivals and local production, resulting in no significant signs of inventory accumulation at ports. Overall, tradable supplies remain tight, further supporting spot price quotes. In summary, domestic PX supply in the short term shows a trend of stability with a slight downward bias.

III. Analysis of Domestic Demand and International Supply Shortage Risks

Demand within the domestic downstream polyester industry chain is gradually recovering month-on-month. Operating rates for PTA, downstream textile manufacturers, and the chemical fiber industry are steadily improving, leading to continued increases in PX feedstock procurement and a steady release of essential demand. Downstream enterprises largely adopt a "purchase-as-needed" strategy; long-term contracts are being executed smoothly, and spot purchases are proceeding in an orderly manner without any panic buying. Internationally, port operations in the Middle East were briefly disrupted by unexpected events but have since fully resumed for crude oil and chemical shipments, with shipping schedules returning to normal. Coupled with plans by major oil-producing nations to slightly increase crude output, upstream feedstock supply is expected to loosen. Global PX supplies remain generally ample with no widespread shortages; only short-term fluctuations in shipping schedules on specific routes have caused slight delays in regional supply circulation.

IV. PX Customs Import and Export Data for April 2026

In April 2026, domestic PX imports and exports followed the established pattern of "stable imports and low exports." Domestic PX self-sufficiency continues to improve, while reliance on foreign sources steadily declines; import volumes for the month saw a slight year-on-year drop, with overseas supplies serving primarily to fill regional supply gaps. The average import price rose slightly month-on-month, influenced by fluctuations in international crude oil prices. Regarding exports, domestic PX is primarily consumed by the local downstream market, keeping export volumes low, with only small quantities flowing to neighboring countries and regions. Cumulative data for January–April shows a slight year-on-year contraction in total PX imports, reflecting the industry trend of expanding domestic refining capacity and rising self-sufficiency, while the impact of foreign trade on the overall market gradually diminishes. V. Analysis of Price Linkage Across the Upstream and Downstream

Naphtha and international crude oil serve as the core feedstocks for PX. Geopolitical instability in the Middle East frequently disrupts crude oil prices, causing significant volatility in naphtha prices; this volatility is subsequently transmitted to PX production costs, acting as the primary driver of current price fluctuations. PX prices find strong cost support when feedstock prices rise and face downward pressure when they fall, demonstrating highly sensitive cost transmission throughout the industry chain. Downstream, prices for polyester feedstocks—such as PTA and ethylene glycol—fluctuate in tandem with PX prices, whereas prices for end-market chemical fibers and textile products remain relatively stable due to constraints imposed by final consumer demand. The industry chain as a whole exhibits a transmission pattern characterized by "upstream volatility, midstream tracking, and downstream stability," with midstream PX processing margins fluctuating dynamically based on the price spread between feedstocks and finished products.

VI. Outlook and Forecast

Domestic PX plant maintenance continues, and the industry's tight supply situation is unlikely to ease rapidly. Coupled with ongoing uncertainty regarding the situation in the Middle East—which keeps crude oil prices prone to fluctuation—PX spot prices are expected to trade within a range, with limited room for movement in either direction. As maintenance units gradually restart, market supply will recover, alleviating the current period of tight supply-demand balance. Major oil-producing nations have raised production targets, leading to expectations of looser global crude oil supplies and a gradual weakening of cost-side support. Meanwhile, the orderly release of new and restarted domestic capacity is gradually restoring PX supply to ample levels; conversely, downstream polyester demand is entering a seasonally stable phase. With the supply-demand balance weakening at the margin, there is a possibility that the price center of gravity will shift downward amidst fluctuations.
