The acidity index reached a new high in the first half of the year, and expectations for high volatility in the second half of the year have increased.

In the first half of 2026, driven by the increase in costs and the contraction of supply in the domestic sulfuric acid market, prices have significantly increased, breaking through historical highs. Looking ahead to the second half of the year, the bottom support on the cost side still exists, but it is expected that the supply-demand game will further intensify, and the sulfuric acid price is likely to show a high-level fluctuation pattern.
