From early to mid-June 2026, the domestic fine chemical and upstream chlor-alkali industry chains entered a phase of consolidation, characterized by increasing seasonal maintenance and shifting regional supply-demand dynamics. With summer temperatures rising nationwide, production loads, logistics paces, and the sentiment of market participants are undergoing subtle adjustments.

By comparing the market conditions from June 5 and June 10, the operational characteristics of core raw materials and the underlying market logic are outlined below:

I. Market Performance and Ten-Day Analysis of Core Raw Materials

1. Liquid Caustic Soda: Transitioning from Regional Divergence to Stability in the North

• Early June Review (June 5): The market exhibited notable regional divergence. In Shandong, procurement prices rose by 15 RMB/ton due to solid demand from major alumina enterprises, prompting independent traders to adjust their prices upward. Conversely, the market in Zhejiang and the Lianghu region (Hunan and Hubei) saw a minor decline due to abundant local supply and strict rigid-demand procurement.

• Mid-June Status (June 10): The market gradually shifted toward steady consolidation. In northern regions like Shandong and Hebei, several chlor-alkali producers initiated scheduled equipment maintenance. Combined with suppressed overall margins for chlor-alkali products, production loads ran below full capacity, keeping liquid caustic soda supplies in the north balanced. Downstream alumina purchasing remained steady, with certain producers attempting to push for higher prices. In contrast, southern markets in East China, Lianghu, and Guangdong remained subdued, leaning toward low-level consolidation with standard factory shipments.

2. Flake Caustic Soda: Anticipated Maintenance in Inner Mongolia Maintains Cautious Sentiment

• Early June Review (June 5): Logistics constraints continued to impact market flows. Although end-users showed minor intent to restock, actual circulation remained weak. Driven by expectations of upcoming new capacities, downstream sentiment leaned bearish regarding long-term prices.

• Mid-June Status (June 10): Supply-demand fundamentals showed no immediate major shifts. However, expectations surrounding scheduled equipment rotations in Inner Mongolia for mid-June injected a degree of cost-side support. On June 9, specific producers raised their new orders by 30 RMB/ton, temporarily improving local transaction sentiment. Nevertheless, given the overall soft tone of the market, traders and downstream buyers remain highly cautious, noting that whether spot prices can be continuously sustained upwards depends on the actual extent of the upcoming maintenance.

3. Liquid Chlorine: Prices Edged Lower from Low Levels Amid Subdued Trading

• Early June Review (June 5): High summer temperatures and constrained profit margins among downstream consumers slowed transactions down. Production units in areas like Jining, Shandong, cut operating loads to avoid storage constraints, pushing liquid chlorine prices down by 100–150 RMB/ton.

• Mid-June Status (June 10): Localized downward adjustments continued in parts of the domestic market. Chlor-alkali enterprises in Liaocheng, Shandong, maintained steady production, but because local liquid chlorine prices were relatively higher than in neighboring regions, quotes were lowered by 50 RMB/ton to stimulate outbound shipments. Meanwhile, facilities in Hubei saw minor supply drops due to maintenance, while downstream inquiries improved. In Anhui, production units ran below full capacity or remained offline, keeping the broader liquid chlorine market stable and observant.

4. Hydrochloric Acid: Firm Transaction Baseline with Minor Supply Fluctuations

• Early June Review (June 5): Prices crept upward within a narrow band. Below-capacity operations in parts of Shandong limited regional supply and activated trading in southwestern Shandong, while Southern and Northern Jiangsu held a firm transaction baseline due to external factors.

• Mid-June Status (June 10): The market entered a phase of range-bound consolidation. Supply lines in Shandong remained steady alongside mild downstream demand and stable shipment paces. In Hubei, tight circulation of byproduct acid supported local transactions, while byproduct acid supply in Ningxia gradually recovered to match local downstream consumption. Mainstream prices for 31% synthetic hydrochloric acid centered consistently within the 150–300 RMB/ton range.

II. Industrial Energy and Downstream Derivatives Analysis

1. Raw Salt and Calcium Carbide: Stable Raw Salt vs. Continued Decline in Calcium Carbide

• Industrial Salt Market: Throughout early-to-mid June, the market maintained a steady rhythm, with domestic ex-factory prices (tax-inclusive) hovering around 241 RMB/ton. For well salt, several facilities resumed operations post-maintenance, ensuring abundant spot supply. For sea salt, collection processes entered their final phases, leaving inventories plentiful and supporting steady purchasing from downstream chlor-alkali plants.

• Calcium Carbide Market: The market faced persistent downward momentum heading into mid-June. Ex-factory prices in the Wuhai region of Ningxia remained low at around 2,150 RMB/ton. Delivered prices to downstream factories in Shandong, Hebei, Shaanxi, and Henan registered downward adjustments. Due to impending maintenance at Inner Mongolian PVC and BDO plants that utilize captive calcium carbide, external sales of calcium carbide increased, compounding inventory clearance pressures for producers.

2. PVC Market: Softening Cost Support Dampens Spot Sentiment

• Calcium Carbide-Based PVC: Impacted by notable declines in primary futures contracts and dropping calcium carbide costs, spot market participants adopted a bearish outlook. Mainstream transaction baselines in East and South China eased lower. Current prices for calcium carbide-based PVC fluctuate between 4,500 and 4,700 RMB/ton (tax-inclusive self-pickup), with low downstream inquiry levels resulting in a quiet trading atmosphere.

• Ethylene-Based PVC: The spot market moved through a period of weak consolidation. Although cost-side support strengthened marginally, downstream resistance to high prices remained apparent. Delivered prices in East and South China hovered within a range of 5,030–5,430 RMB/ton.

III. Market Summary and Future Outlook

Cumulatively, the performance of the upstream chlor-alkali industry chain in early-to-mid June highlights a distinct "seasonal maintenance period":

1. Supply-Side Balance: Scheduled seasonal turnarounds at northern chlor-alkali units and Inner Mongolian flake caustic soda lines have partially offset the soft demand environment, providing liquid and flake caustic soda with short-term support under low-margin conditions.

2. Cost Transmission Pressures: While price corrections for calcium carbide and liquid chlorine have alleviated the initial material cost baseline for downstream fine chemicals (such as chloroacetic acid and sodium chloroacetate), the fact that downstream plastics (PVC) and agrochemical end-markets are in seasonal slow periods means overall industry margins remain under structural adjustments.

Outlook: Moving into mid-to-late June, the domestic chlor-alkali market will continue to fluctuate based on the actual execution of regional maintenance and adjustments in production loads during hot weather. Backed by low inventories and localized turnarounds, foundational raw materials are unlikely to experience deep declines; however, capped by quiet downstream demand, substantial upward momentum remains restricted. The broader market is expected to maintain a narrow, range-bound consolidation pattern. Companies across the industrial chain are advised to monitor regional production schedules closely and align their procurement structures accordingly.
