On June 17, 2026, the domestic fine chemical and upstream chlor-alkali industrial chains generally exhibited a low-level bottoming-out pattern characterized by "localized strength, regional divergence, and rational supply-demand maneuvering." Influenced by facility maintenance schedules in certain regions, shifting paces in downstream rigid procurement, and varying inventory levels across major production hubs, transaction baselines across different sectors performed distinctively.

Based on the latest data for bulk raw materials, a comprehensive breakdown of the actual operational status and underlying market logic across the key segments of the chlor-alkali industrial chain is outlined below:

I. Operational Status of Core Raw Materials

1. Liquid Caustic Soda: Localized Price Hikes paired with Flexible Regional Adjustments

The domestic liquid caustic soda market displayed localized upward adjustments today. In the Shandong region, purchasing prices by large-scale alumina enterprises rose by another 15 RMB/ton due to relatively firm demand. While prices were adjusted upward accordingly, purchasing enthusiasm from other non-alumina downstream sectors in the province remained soft, leading to highly flexible adjustments in local spot quotes. In Northeast China (Liaoning), some chlor-alkali installations remain under maintenance; with moderate downstream demand, chemical plants face minimal inventory pressures, maintaining steady market operations. In Central China (Henan), a few previously offline facilities are gradually resuming production, raising expectations for an increase in supply while terminal demand runs sluggishly stable. In Southwest China, market supply remains abundant, prompting chemical plants in Sichuan to actively clear inventories amid flat downstream purchasing, while the Chongqing region is consolidating ahead of scheduled turnarounds by certain manufacturers.

2. Flake Caustic Soda: Major Plants Intensify Price Support Amid Steady Shipments

The domestic flake caustic soda market is expected to run steadily today. In Inner Mongolia, a leading mainstream factory raised its new order quotes by 30 RMB/ton, primarily because its flake caustic soda units are undergoing maintenance. This allows the enterprise to focus on digesting its own inventory, resulting in negligible sales pressure and a smooth upward price adjustment. Other chemical plants are focused on active shipping. As downstream demand continues to run weak and overall operation rates among flake caustic soda consumers remain average, terminal buyers are maintaining a cautious, wait-and-see approach. New transactions in the spot market are driven strictly by rigid immediate needs, ensuring stable and balanced factory shipments overall.

3. Liquid Chlorine: Localized Compensatory Rises with Balanced Supply and Demand

The domestic liquid chlorine market registered localized price gains today. In the Dongying area of Shandong, chlor-alkali enterprises maintained stable operating rates alongside moderate downstream demand. Supported by price gains in surrounding regions, factory shipments progressed smoothly, prompting a compensatory rise of 50 RMB/ton in liquid chlorine quotes today, while transaction dynamics in other parts of the province remained stable. In Central China (Henan), equipment maintenance at certain chlor-alkali plants has concluded, but this has yet to show a noticeable impact on the supply side; downstream buyers are picking up cargo steadily, keeping factories focused on active shipping with quotes expected to remain stable. In East China (Anhui), chlor-alkali units are generally running below full capacity, and with flat downstream buying interest, trading sentiment remains mild, pointing to stable liquid chlorine prices.

4. Hydrochloric Acid: Consolidation and Flat Balancing Amid Rising Local Supply Expectations

The hydrochloric acid market is anticipated to undergo flat consolidation today. In Shandong, the supply side maintains standard capacities, but with average downstream demand follow-up, manufacturers are actively pushing shipments, indicating a potentially softer market trajectory ahead. In Henan, previously offline enterprises are on the verge of resuming production, which expands future supply expectations; concurrently, support from the cost side is weakening, prompting a clear intent among factories to accelerate shipments, which may put downward pressure on mainstream quotes. In Yunnan, available commercial cargo is limited, and backed by increasing procurement demand from surrounding regions, local prices were lifted moderately. The Chongqing market is well-supported by adjacent regions, showing improved supply-demand dynamics and active trading. Currently, mainstream prices for 31% synthetic acid remain concentrated between 150 and 300 RMB/ton.

II. Basic Energy and Downstream Derivatives Analysis

1. Industrial Salt and Calcium Carbide: Industrial Salt Runs Steady, Calcium Carbide Consolidates at Low Levels

• Industrial Salt Market: The industrial salt sector is tracking a stable course, with the domestic average factory price (including tax) hovering at 242 RMB/ton. For well salt, facility operating rates remain fundamentally stable; although a few well salt enterprises in Henan are offline for maintenance, inventory levels are low, and downstream consumers are purchasing strictly based on immediate needs, leaving factories free from shipping pressures. For sea salt, harvesting has concluded at several farms, ensuring abundant inventory levels; downstream chlor-alkali demand is stable, and factory offers remain firm, indicating zero immediate fluctuations in the sea salt sector.

• Calcium Carbide Market: The domestic calcium carbide market is maintaining a cautious, observant stance today. The factory ex-works price in the Wuhai region of Ningxia sits around 2,200 RMB/ton, with no new adjustments reported for downstream delivered quotes. At present, available calcium carbide supply remains at a relative low, allowing manufacturers to maintain decent shipment levels and ensuring firm ex-works pricing in Ningxia. On the consumption side, overall arriving volumes at downstream facilities are respectable; however, because several downstream PVC and BDO enterprises are undergoing maintenance, purchasing plants also possess the leverage to resist higher quotes. Consequently, the calcium carbide market is seeing flat consolidation, with close attention directed toward future operating rates of both upstream and downstream producers.

2. PVC Market: Carbide-Based PVC Inches Lower, Ethylene-Based PVC Sluggish in Off-Season

• Carbide-Based PVC: The carbide-based PVC market may continue to experience downward pressure today. Lacking upward drivers in the PVC futures main contract, domestic spot prices are expected to edge lower within a narrow range, with transactions concluded primarily through individual negotiations. Given that raw calcium carbide costs are holding steady, carbide-based PVC manufacturers face manageable cost pressures, maintaining an industry operating rate of 79.39%. However, because overall inventory levels are high and the supply side remains robust, downstream absorption is limited. Buying remains confined to small-volume, hand-to-mouth purchasing, prompting PVC enterprises to offer discounts and concessions to stimulate sales. Mainstream transaction ranges in East and South China are expected to settle around 4,450–4,650 RMB/ton (self-pickup, tax included).

• Ethylene-Based PVC: The ethylene-based PVC market is expected to see quiet consolidation, with transactions in East and South China dominated by spot negotiations amid a persistently thin trading atmosphere. Ethylene-based PVC producers are currently facing shipment pressures; manufacturing costs remain high while facility operating rates hover around 40%. Transactions are being handled case-by-case, with selling prices dipping below production costs, leading to sustained margin losses. Downstream acceptance of new orders is highly limited, and further dampened by off-season effects, buyers show zero intention to stockpile raw materials, keeping aggregate demand depressed. Delivered price ranges in East and South China are expected to fluctuate within 4,950–5,220 RMB/ton (including tax and freight).

III. Market Outlook and Technical Summary

Taking today's comprehensive performance into account, the upstream chlor-alkali industrial chain is navigating a classic horizontal consolidation phase at lower price boundaries, directly caught between "anticipated facility maintenance rotations and restrictive off-season terminal demand":

1. Cost Buffering from Liquid Chlorine and Caustic Soda: Firm pricing in northern liquid caustic soda driven by alumina demand, combined with localized compensatory price gains in liquid chlorine, has significantly restricted the room for downstream fine chemical derivatives (such as Chloroacetic Acid and texturing auxiliaries) to make further blind downward concessions. This rising cost floor provides a natural line of defense for spot pricing.

2. Weak Structural Demand Ceilings: With the seasonal off-peak effect fully manifest, operating loads across downstream PVC and精细化工 sectors remain ordinary. The clear absence of large-volume stockpiling or speculative contract purchasing means the momentum to pass upstream cost increases down to end consumers remains insufficient.

Outlook: In the short term, prices for most foundational raw materials across the domestic chlor-alkali value chain are highly likely to fluctuate within a low-level, range-bound corridor. Because factory profit margins have already been heavily compressed, prices are structurally resistant to further drops and lean toward steady stabilization. Any definitive breakout or shift in market direction will require close monitoring of actual production load adjustments by major upstream plants and the shifting logistical distribution of raw glacial acetic acid, liquid chlorine, and calcium carbide.
