Citric acid: Cycles
Maize, coal and Chinese capacity drive the swings
What this tab covers How its prices and margins move: past booms and busts with price levels, the spread or margin that the industry watches, the drivers of the cycle and the metrics to track.Citric acid behaves like a commodity. Prices follow Chinese maize and energy costs and Chinese capacity additions, with export prices swinging by half or more over a few years (indicative). Demand grows steadily with beverages and detergents, so most cycles come from supply. The floor is the cash cost of the largest Chinese plants; the ceiling is set by substitution with other acids and by restarts of idle Chinese lines. Western prices sit above Chinese levels because of anti-dumping duties. Public price series are thin, so input prices and Chinese producers' margins are the practical gauge.
The spread to watch Citric acid price minus sugar costPrice minus about 1.2 x glucose or sugar cost per tonne is the gross margin. Glucose in China tracks maize at roughly RMB 2,100-2,500/t (2024-2026, Faxian Gongchang amino acid report); citric prices are not public in sources reached.
Booms and busts
- 2008-2009
EU and US imposed anti-dumping duties on Chinese citric acid after a surge of low-priced exports, splitting the market into a duty-protected West and a Chinese-priced rest of world.
price numbers not public in sources reached
- 2021-2022
Maize, coal and freight costs rose and Chinese power rationing in late 2021 cut output; export prices rose sharply before easing in 2022-2023 (indicative).
World Bank maize rose from $144/t (May 2020) to $348/t (Apr 2022) (maize tile); citric export prices roughly doubled (indicative)
- 2023-2025
New Chinese capacity and weaker demand pushed export prices back down towards cash cost (indicative).
maize fell to $175/t in 2025 in 2010 dollars (World Bank via maize tile); citric export prices of about $700-900/t (indicative)
What drives the cycle
- Chinese maize and coal prices. Set the cost of glucose and steam for most of the world's capacity.
- Chinese capacity and export policy. New lines and changes in export VAT rebates move world supply.
- Trade defence. EU and US anti-dumping duties keep Western prices above Asian levels.
- Beverage and detergent demand. Steady growth of about 4-6% a year in value (TBRC; Fortune).
