• Caustic soda prices rose in Week 24 as alumina producers raised their procurement prices, improving seller confidence and supporting higher spot market offers
• Steady demand from textile and water treatment users in Week 24 kept spot absorption consistent and prevented inventory accumulation at producer facilities
• Prices extended the gain in Week 25 as maintenance at chlor-alkali plants across Shandong reduced operating rates and tightened prompt supply availability
• East China maintenance schedules ran in parallel with Shandong outages in Week 25, compounding the supply constraint and giving producers additional pricing leverage
• Export orders from Southeast Asia reduced domestic inventory pressure in Week 25 while rising electricity tariffs provided a cost-side floor supporting firm producer offers

Caustic soda prices rose through Week 24 as conditions in the alumina sector provided the initial push to market sentiment. Alumina producers revised their caustic soda procurement prices upward during the week, a signal that downstream demand from one of the market's largest industrial consumers was strengthening. The upward revision in alumina buyer pricing lifted seller confidence across the spot market, with producers and traders adjusting their offers in response to the improved demand signal.

Demand from other downstream channels held at consistent levels through Week 24, with textile processors and water treatment operations maintaining their routine procurement pace and preventing inventory from building at chlor-alkali production facilities. The steadiness of off-take across these sectors reinforced the demand picture and gave sellers grounds to resist downward pressure on pricing, with the market closing Week 24 at firmer levels than it had entered.

Week 25 extended the upward move through a different mechanism, with the supply side replacing demand confidence as the primary price driver. Scheduled maintenance work across chlor-alkali plants in Shandong, one of China's principal caustic soda producing provinces, reduced operating rates from levels seen in the prior weeks, limiting the volume of prompt material available to buyers. East China facilities running parallel maintenance schedules compounded the supply constraint, with production across two significant regional hubs simultaneously below normal capacity.

The reduction in near-term availability gave producers additional pricing leverage in Week 25 that they had not held to the same degree a week earlier, allowing offers to move higher without buyer resistance forcing a pullback. Export orders from Southeast Asia drew down domestic inventories that might otherwise have buffered the impact of the maintenance period, tightening the supply picture further. Rising electricity tariff costs across chlor-alkali facilities provided a cost-side rationale for producers to maintain firm pricing throughout Week 25, reinforcing their ability to hold offers at elevated levels even when individual buyers attempted to negotiate lower.

For procurement teams in alumina, textile and water treatment sectors, the two-week sequence reflects a market where demand confidence and supply restriction arrived in sequence rather than simultaneously, producing a sustained rather than temporary price increase. Buyers who secured prompt volumes in Week 24 before the maintenance-driven tightening in Week 25 were better positioned on cost, while those relying on spot procurement in Week 25 faced the compounded effect of both improved demand confidence and reduced supply availability.
