Sulphuric Acid Prices Stabilised in February 2023

According to the National Bureau of Statistics, national sulfuric acid (100% basis) output in June 2026 reached approximately 7.923 million tons (vs. 8.365 million in May, 8.948 million in April, and 9.637 million in March, showing a month‑on‑month decline). The year‑on‑year change for the month was about ‑10%. For the first half of the year (January–June), cumulative production totaled roughly 52.223 million tons, a year‑on‑year decrease of about ‑0.1% (down from +1.9% in the January–May period, mainly due to the sharp 10% drop in June). Production remains heavily concentrated in smelting and phosphate‑fertilizer provinces such as Yunnan, Inner Mongolia, Guangxi, Anhui, Henan, and Shandong—with Yunnan ranking first at about 1.24 million tons per month. Smelter acid (by‑product from copper/zinc processing) forms the supply backbone, while acid for phosphate fertilizer drives the bulk of demand.
