The U.S. Magnesium Chloride market was stable in November 2025, with prices remaining at October levels, supported by moderate de-icing demand and average activity from downstream users in the building and paints industries despite opposing movements in feedstock prices.
U.S. Magnesium Chloride prices remained stable in November 2025, the same as in the previous month. Such balance was observed in spite of the opposite trends observed in the raw materials markets where Magnesium Hydroxide was pressured upwards by 2.3% and Hydrochloric Acid was pressured downwards by 2%. The stability of the Magnesium Chloride market was interpreted as a sign of well-balanced supply and demand as producers faced early winter weather and relatively moderate consumption from downstream.
Magnesium Chloride market fundamentals were generally stable through November, with prices remaining flat after having fallen about 1% in October. This stability came against the background of increasing prices for Magnesium Hydroxide during the month. An increase in this raw material costs also offset the continued decline in prices for Hydrochloric Acid. As a result, the production economics on a whole relatively stable, and Magnesium Chloride producers could take consistent pricing approaches without any immediate need for shifting their strategies.
Downstream demand trends provided a mixed signal for Magnesium Chloride usage in the month of November. The residential construction was still weak as new housing starts was down over 8.5% in August and holding steady into the fall. This deceleration has had a direct impact on architectural coatings demand as both new construction and renovation activities have fallen short of seasonal expectations. The paints and coatings, a known large user of Magnesium Chloride, saw cautious buying as builders continued to struggle with high mortgage rates and construction costs that kept pipelines of residential projects tightly capped through November.
De-icing applications started to pick up gradually in November, but Magnesium Chloride orders were still behind from what could be expected in a full winter. Municipal agencies and transportation departments began seasonal preparations, stockpiling strategically for expected winter weather. But unseasonably warm weather in most of the key regions in early November reduced demand pressure for urgent buying of Magnesium Chloride. This average seasonal pickup was in contrast to previous years when November is normally when demand starts to increase as the winter weather picks up across the northern states.
Industrial usage of Magnesium Chloride held steady but unimpressive in November. Industrial consumers using the compound in numerous chemical treatment and dust control applications held their orders at baseline levels. The flow of goods was steady as producers were holding just sufficient stock to cover the demand. This trimming was in line with the currently cautious sentiment from the market as the industrial buyers were generally reserved in their Magnesium Chloride purchasing on the back of the uncertain macro-economic environment which was weighing on manufacturing output and capex decisions.
Looking to December, market participants expect downward pressure of about 1.7% on the price of Magnesium Chloride, despite growth in seasonal de-icing demand. An increase in de-icing demand usually boosts usage in the coldest winter months leading to higher prices. But seasonal trends may be offset by weakening trends in the construction-related segments. Feedstock signals will continue to be important, especially if Magnesium Hydroxide costs rise further and Hydrochloric Acid prices stabilize, which could cause further narrowing of production margins and result in the need to adjust Magnesium Chloride pricing as producers strive to balance cost pressures with the competitive market environment as the year ends.
