Electronic-grade hydrogen fluoride, a critical chemical in semiconductor manufacturing, is seeing sharp price increases as global chip production expands. Suppliers have raised prices by 20% to 30%, while Taiwanese and South Korean chipmakers are accelerating purchases to lock in supply.
The chemical, essential for wafer cleaning and etching, is facing rising production costs due to higher sulfur prices linked to logistics disruptions near the Strait of Hormuz. Some South Korean manufacturers are already paying premiums of around 40% to secure material from mainland suppliers, signaling tight availability.
Prices surge as chipmakers secure supply

Supply chain constraints push costs higher
Hydrogen fluoride production depends on fluorspar and sulfuric acid, both of which are under pressure. The supply chain runs from raw fluorspar to anhydrous hydrogen fluoride and finally to high-purity electronic-grade products.
Only the highest grade, G5, meets the requirements for advanced chips at 14nm and below. Spot prices for G5 material have climbed to between 180,000 and 200,000 yuan per ton, with top producers reporting margins of 50% to 60% amid an estimated global shortage of about 70%.
China expands role in high-end supply
Japan has traditionally dominated high-end hydrogen fluoride, with Stella Chemifa, Morita Chemical, and Central Glass accounting for nearly 40% of global output. South Korean firms such as Soulbrain and ENF Technology still rely heavily on imports, sourcing roughly 90% of their anhydrous hydrogen fluoride from China.
Chinese producers have rapidly scaled up G5 capacity and now exceed Japan’s total output, positioning the country as the primary global supplier. Companies such as Do-Fluoride and Juhua lead in certified production capacity.
Stock rally raises questions over fundamentals
Fluoride chemical stocks in China have surged since mid-May, with many trading near 52-week highs. However, the rally has highlighted a divide between companies benefiting from real demand and those driven by market speculation.
Do-Fluoride reported a 480% year-on-year jump in first-quarter profit to 376 million yuan, but most of its earnings came from lithium-battery chemicals rather than semiconductor materials. Its lithium hexafluorophosphate business alone is expected to generate more than 2 billion yuan in profit.
In contrast, Zhongjuxin’s share price has quadrupled despite weak financial performance, including a first-quarter profit of just 6.37 million yuan following a loss in 2025. The company has stated that hydrogen fluoride contributes only a small portion of its revenue and confirmed it has no direct pricing agreements with major South Korean clients.
Diverging business progress across companies
Some firms are making measurable progress in semiconductor chemicals. Jianghuai Chemical has posted more than 200% growth in wet-process chemical sales, focusing on G4-grade products, while its G5 output is still pending certification.
Jingrui Materials has already secured mass orders for G5 sulfuric acid from Semiconductor Manufacturing International Corp., increasing that segment’s share of revenue from 5% to 20%. Meanwhile, upstream supplier Jinshi Resources has gained from higher prices, supported by its large fluorspar reserves and hydrofluoric acid capacity.
Trading patterns signal shifting sentiment
Recent trading data point to a divergence in market participation:
- Institutional desks were net sellers of leading chemical stocks in June
- Retail traders increased buying during the same period
- High turnover rates suggest active short-term positioning
This pattern indicates that more experienced market participants may have been locking in gains while retail momentum pushed prices higher.
AI-driven chip demand underpins outlook
The demand surge is closely tied to rapid growth in the semiconductor sector, particularly driven by artificial intelligence. The global semiconductor market is projected to expand from $90.26 billion in 2026 to $142.43 billion by 2035, increasing the need for high-purity materials like G5 hydrogen fluoride.
Taiwanese and South Korean manufacturers’ willingness to pay premiums reflects the critical role of these chemicals in producing advanced logic and memory chips used in AI systems.
Key catalysts will test elevated valuations
Several near-term events are expected to shape the sector’s trajectory. Further price adjustments by South Korean chipmakers in July will indicate how tight supply remains. Interim financial results due by mid-August will show whether companies can translate demand into earnings. The planned IPO of Changxin Technology is also likely to draw significant market attention and liquidity.
Outlook remains strong but risks are rising
Hydrogen fluoride prices continue to face upward pressure from supply shortages, strong chip demand, and regional import dependence. However, many related stocks have already risen three- to five-fold and are trading at multi-year highs.
With institutional selling emerging and valuations stretched, upcoming earnings reports are likely to determine which companies can justify their gains and which may face renewed volatility.
