Phosphoric Acid (H₃PO₄) – Used for Etching Silicon Nitride Price Trend in Past Five Years and Factors Impacting Price Movements
Over the past five years, the Phosphoric Acid (H₃PO₄) – Used for etching silicon nitride price trend has reflected substantial volatility. Between 2020 and 2021, prices hovered around $870–$900 per metric ton (MT), driven by stable semiconductor sector demand and a relatively balanced production environment in Asia-Pacific.
In 2022, however, global disruptions caused by shipping container shortages and raw material inflation escalated the Phosphoric Acid (H₃PO₄) – Used for etching silicon nitride price news considerably. Average prices rose sharply to $950–$980/MT. Countries heavily reliant on imports, such as South Korea and Japan, reported spikes exceeding $1,000/MT during periods of acute shortage.
The year 2023 introduced a cooling period, with prices retracting slightly to the $890–$910/MT range, largely due to improved logistics and expanded production capacities in Vietnam and India. However, rising energy costs sustained overall price levels above pre-pandemic norms.
In 2024, prices began climbing again as stricter environmental policies in China, a major producer, reduced available supplies. Average spot prices in major Asian markets escalated to $1,020/MT by Q3 2024. The demand for advanced semiconductors requiring high-purity Phosphoric Acid (H₃PO₄) – Used for etching silicon nitride further exacerbated the pressure on supply chains.
Entering 2025, the Phosphoric Acid (H₃PO₄) – Used for etching silicon nitride price trend shows a mixed pattern. While new capacities have come online in Southeast Asia, disruptions from European plants due to energy rationing are supporting a firm floor for prices.
Key factors influencing price movements in these years include:
- Volatility in phosphate rock costs and availability
- Regulatory curbs on chemical plant emissions, particularly in China and the European Union
- Shifts in semiconductor technology towards advanced nodes requiring higher purity acids
- Logistics challenges including shipping bottlenecks and higher freight rates
- Trade barriers and tariffs between major economies
The trajectory over the past five years highlights that price cycles for Phosphoric Acid (H₃PO₄) – Used for etching silicon nitride are increasingly tied to semiconductor industry cycles, more so than to traditional agricultural demand for industrial-grade phosphoric acid.

Phosphoric Acid (H₃PO₄) – Used for Etching Silicon Nitride Production Trends by Geography
In 2025, the global production of Phosphoric Acid (H₃PO₄) – Used for etching silicon nitride is characterized by significant regional diversification, technological upgrades, and evolving government regulations. A shift towards producing ultra-high-purity grades required by the semiconductor industry has reshaped the production landscape.
China
China remains the largest producer of Phosphoric Acid (H₃PO₄) – Used for etching silicon nitride globally. Despite stringent environmental norms, the country maintains a stronghold through its vertically integrated phosphate mining and chemical manufacturing sectors. Chinese manufacturers are increasingly focusing on producing electronics-grade phosphoric acid to cater to growing domestic semiconductor demand. However, in 2025, capacity expansions are slowing down due to carbon neutrality targets and stricter water usage policies impacting chemical plants in provinces like Hubei and Sichuan.
United States
The United States continues to produce limited quantities of high-purity Phosphoric Acid (H₃PO₄) – Used for etching silicon nitride. Most production is focused around specialized chemical companies supporting domestic semiconductor fabrication facilities in states such as Arizona, Texas, and Oregon. New investments in upgrading purification systems were announced in late 2024, aimed at increasing domestic self-reliance amidst ongoing supply chain vulnerabilities. However, the US still remains a net importer for certain high-volume needs.
India
India is emerging as a fast-growing producer of electronics-grade Phosphoric Acid (H₃PO₄) – Used for etching silicon nitride. Domestic chemical companies are ramping up capabilities to support India’s semiconductor manufacturing ambitions under the Production Linked Incentive (PLI) scheme. Plants in Gujarat and Andhra Pradesh are upgrading their purification facilities, and pilot plants operational since 2023 have started commercial production by mid-2025. However, challenges around raw material purity and power availability persist.
Japan and South Korea
Both Japan and South Korea have traditionally imported a large share of their phosphoric acid requirements. However, in 2025, both countries have seen marginal increases in domestic production, primarily through specialty chemical divisions of major conglomerates. These facilities are tightly integrated with their semiconductor customers, ensuring supply chain reliability. Japanese production emphasizes extremely stringent purity standards, while South Korea focuses on volume flexibility.
Vietnam and Thailand
Vietnam and Thailand are gaining prominence as alternative production hubs. Supported by favorable investment policies and lower operational costs, several multinational chemical companies have established manufacturing plants focusing exclusively on high-purity grades.
