Electronic‑Grade High‑Purity Ammonia – The “Invisible Blood” of Semiconductor Manufacturing – Grows at Over 10% Annually

In tHe vast semiconductor supply chain,high‑purity ammonia (NH₃) may not be the most visible name, but its importance is being re‑evaluated.

According to a recent Global Info Research study, the global electronic‑grade ammonia (≥99.999%) market was worth USD 147 million in 2025 and is expected to reach USD 207 million by 2032, at a CAGR of 5.1%. Other research houses are more optimistic: one projects USD 152.4 million in 2025 rising to USD 280.6 million by 2034 (CAGR 6.9%). HTF Market Intelligence offers an even more aggressive figure – USD 48 billion for 2025 (note: this is a market research forecast and should be treated as indicative) – but the upward trend is unanimous.

The drivers are multiple. First, semiconductor expansion: high‑purity ammonia is a critical precursor for chemical vapour deposition (CVD) and metal‑organic CVD (MOCVD), used in LED chips, semiconductor wafers and thin‑film transistors. As nodes shrink to 3 nm and below, purity requirements reach parts‑per‑trillion (ppt) levels – any trace impurity can ruin an entire batch of high‑value wafers.

Second, the rise of third‑generation semiconductors: GaN and SiC devices are booming, and ammonia is the core raw material for GaN MOCVD epitaxy. Electric vehicles, 5G and fast‑charging technologies are continuously raising demand.

Third, geopolitically driven supply‑chain restructuring: the global semiconductor gas industry has long been oligopolistic, dominated by Linde, Air Liquide, Taiyo Nippon Sanso and others with decades of technical and certification barriers. But 2026 is different. The announced permanent shutdown of two Japanese tungsten hexafluoride producers from 1 July has sent a shockwave through the entire specialty gas sector. This “supply anxiety” is forcing wafer fabs worldwide to diversify their sourcing, opening an unprecedented window for domestic alternatives.

China plays a key role in this transformation. According to Kaiyuan Securities, although the localisation rate for electronic specialty gases has been steadily rising, the industry still faces structural challenges – technical gaps, lengthy certification processes, capital intensity and supply‑chain risks. However, policy is pushing forward: in January 2026, China’s Ministry of Commerce initiated an anti‑dumping investigation into dichlorosilane imports from Japan, further incentivising fabs to adopt local suppliers.

For Chengdu Hongjin Chemical, the strategic importance of the high‑purity ammonia product line is clear. The company’s 7N (99.99999%) ammonia has already passed certification tests at several domestic semiconductor material firms. In this golden window for import substitution, the ability to consistently improve purity, scale capacity and shorten certification cycles will determine how large a share of this semiconductor feast the supplier can claim.
