On June 5, 2026, the domestic fine chemical and upstream chlor-alkali industry chains exhibited a pattern characterized by localized fluctuations and regional divergence. Impacted by seasonal factors, downstream operational rates, and changes in local supply-demand dynamics, various bulk raw materials displayed distinct price trends. 

I. Market Performance of Core Raw Materials

1. Liquid Chlorine: Notable Price Correction Amid Supply Pressures Influenced by the anticipation of high summer temperatures and restricted profit margins among downstream chlorine-consuming enterprises, the domestic liquid chlorine market experienced a downward trend in trading volume and sentiment today. Chlor-alkali enterprises in major producing areas such as Jining, Shandong, implemented load-reduction strategies. However, to mitigate safety and production risks associated with potential storage capacity pressures, liquid chlorine prices in relevant regions were adjusted downward by 100–150 RMB/ton to stimulate shipments. Resources in East China, Henan, and Northern Jiangsu remain relatively abundant, while downstream procurement remains cautious and primarily based on immediate demand.

2. Liquid Caustic Soda: Regional Divergence with Localized Increases The liquid caustic soda market demonstrated uneven performance across different regions today. In Shandong, supported by increased procurement from major alumina enterprises, purchase prices rose by 15 RMB/ton, prompting flexible upward adjustments in spot prices for independent traders and reflecting resilient local demand. Conversely, in regions such as固定, Zhejiang, Hunan, and Hubei, ample overall market supply and a procurement focus on essential restocking led to a softer trading atmosphere and a slight decline in recent prices. South China and the Guangxi region remained stable, fluctuating within a narrow, consolidated range.

3. Hydrochloric Acid: Slight Upward Adjustments Amid Variable Operational Rates The domestic hydrochloric acid market edged slightly higher today within a narrow range. Certain enterprises in Shandong operated below full capacity, leading to constrained regional output. Consequently, trading activity in southwestern Shandong was relatively active, accompanied by marginal price increases. While chlor-alkali production rates in Henan remained elevated, shipping momentum slowed down, keeping prices stable. Supported by specific external factors, markets in Northern and Southern Jiangsu experienced steady trading, with the overall transaction baseline remaining firm.

II. Industrial Energy and Downstream Derivatives Analysis

1. Raw Salt and Calcium Carbide: Stable Raw Salt vs. Weakening Calcium Carbide The industrial salt market remained broadly stable today, with the average domestic ex-factory price (inclusive of tax) hovering around 240 RMB/ton, and well salt and sea salt enterprises maintaining active shipping schedules. In contrast, the calcium carbide market continued to face downward pressure. Ex-factory prices in the Wuhai region declined further by 50 RMB/ton today (mainstream prices dropping to approximately 2,250 RMB/ton), which triggered corresponding reductions in downstream delivered prices in Henan, Shandong, and Hebei. Reduced procurement volumes of calcium carbide this week intensified supply-demand imbalances, leading manufacturers to adopt discount strategies to facilitate inventory clearance.

2. PVC Market: Futures-Spot Alignment Lowering Market Sentiment Driven by declining production costs from calcium carbide and downward fluctuations in related futures contracts, the domestic spot PVC market remained subdued today. In mainstream markets across East and South China, traders maintained a highly cautious approach, and transaction baselines edged lower. Currently, mainstream prices for calcium carbide-based PVC fluctuate within a range of 4,650–4,780 RMB/ton (tax-inclusive self-pickup). Although ethylene-based PVC received modest cost-side support, downstream inquiry levels remained low, leaving delivered prices ranging between 5,070 and 5,550 RMB/ton, with overall market activity awaiting improvement.

III. Market Summary and Outlook

In summary, the interconnectedness and mutual constraints within the upstream chlor-alkali industry chain remain prominent. The temporary price correction of liquid chlorine has partially alleviated initial cost pressures for downstream fine chemical materials, such as chloroacetic acid and sodium chloroacetate. However, because co-products like hydrochloric acid and caustic soda show varying trends by region, comprehensive production costs are undergoing dynamic adjustments.
