Handuck Chemical broke ground on a new tetramethylammonium hydroxide (TMAH) plant in Pyeongtaek, Korea, investing 130 billion won. The expansion creates dual production bases to improve supply stability and logistics for surging semiconductor demand, which is likely to stabilize TMAH prices.
ACME Green Molecules finalises a $1 billion long-term deal to export 100,000 tonnes per year of green methanol to Japan's Mitsubishi Gas Chemical, marking India's debut as a global supplier of RFNBO-compliant marine fuel. The agreement underscores strong demand for renewable methanol in shipping and supports India's investment in new production capacity, likely keeping green methanol prices elevated as contracted supply tightens availability.
Tetramethylammonium Hydroxide (TMAH) is a quaternary ammonium compound used as a high purity reagent in semiconductor photoresist development, silicon wafer cleaning, and photoresist stripping. Its price path stays closely linked to ammonium chloride and ammonia feedstocks alongside the health of global electronics and chip manufacturing, its dominant end use base.
Through H1 2026, TMAH sentiment reflected a gradual transition from the demand caution that weighed on the market through much of 2025. In Asia, which holds the bulk of capacity across China, Japan, South Korea, and Taiwan, the year began softly before recovering as foundry activity accelerated on renewed investment in advanced logic and memory nodes. Chinese supply was broadly adequate but tempered by environmental compliance measures that constrained output at certain facilities, quietly underpinning offers. Europe firmed modestly as recovering electronics, specialty cleaning, and organic synthesis demand drew down comfortable inventories, with Asian imports the primary replenishment source and shipping delays translating quickly into tighter availability. North America mirrored this constructive tone, supported by domestic fabrication aligned with reshoring linked capacity investment and incremental photovoltaic and precision cleaning demand.
Analyst Insight
According to Procurement Resource, TMAH prices should stay supported through H2 2026, contingent on continued recovery in semiconductor capital expenditure and stable feedstock availability. Renewed softness in chip demand or a correction in upstream ammonia markets would reintroduce downward pressure, making fab utilisation rates and ammonia costs the two variables procurement teams should track most closely.

Asia
In Asia, Tetramethylammonium Hydroxide prices trended lower during Q2’25, mainly due to weak demand from the semiconductor and electronics sectors. Key markets like South Korea and Taiwan saw slower chip production, which reduced the need for high-purity chemicals like TMAH.
At the same time, regional supply remained steady, with consistent output from local manufacturers and imports from Japan and China. Even though freight costs across intra-Asia routes rose steadily, their impact on overall pricing was limited due to existing stockpiles and cautious buying behaviour. Toward the end of the quarter, prices showed slight signs of firming as logistical delays at key ports like Singapore began to affect timely deliveries.
Europe
In Europe, TMAH prices fell sharply through the quarter. The primary reason was subdued demand from electronics and industrial cleaning segments, as well as improved domestic production. Large-scale plants resumed operations after earlier slowdowns, and healthy import volumes kept the market well-supplied.
With little seasonal pressure and steady supply chains, buyers avoided large spot purchases and preferred long-term contracts, further pushing down prices. Despite some concerns around supply disruptions from North Africa and Asia, inventories across Western Europe stayed comfortable, helping to prevent any major price spikes.
North America
North America also saw a downward trend in TMAH pricing during Q2’25. After a strong first quarter, demand softened from the semiconductor and precision manufacturing industries, particularly as some production lines paused for scheduled maintenance. Supply remained stable, supported by steady operations at major production hubs and imports from Asia.
While a heatwave in June caused localized power issues in parts of the U.S., it didn’t lead to widespread disruptions. Inventory buildup earlier in the year helped cushion short-term tightness, keeping prices relatively stable through most of the quarter.
Tetramethylammonium hydroxide is a quaternary ammonium salt that forms a strong alkaline solution on dissolution in water. Naturally, it is a colorless liquid or solid with high deprotonating properties. It can dissolve organic materials and thus is a valuable component in processes like photoresist development and cleaning of silicon wafers in the semiconductor industries.

A bipolar membrane is used to convert tetramethyl ammonium chloride to tetramethyl ammonium hydroxide via the process of electrolysis. The conversion efficiency of this bipolar membrane is dependent on the concentration of feedstock material and decreases with the increase in the flow of current.
