Dyes: Cycles

How pollution crackdowns, not demand, drive dye price spikes

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.

Dye prices are set by Chinese producers and swing with environmental enforcement and intermediate shortages more than with demand. When China closes plants or chemical parks, intermediates such as H acid or reduction products spike and dye prices follow. When enforcement eases and textile demand softens, prices drift down for years. Indian producers gain export share when Chinese supply is disrupted and lose margin when Chinese prices fall. The floor is the cash cost of integrated Chinese plants; the ceiling is set by mills switching dye classes or suppliers.

The spread to watch Dye price minus key intermediate cost (e.g. reactive dye vs H acid)

Not published as a spread. With H acid at RMB 70,000-90,000/t (2025) and reactive dyes at about RMB 21,000/t standardised, margins depend on dye strength and the H acid fraction per tonne of commercial dye (indicative).

Booms and busts

2017-2019
China's central environmental inspections and the March 2019 Xiangshui (Jiangsu) chemical park explosion closed many intermediate and dye plants, causing intermediate and dye shortages (indicative).

2021
Post-COVID textile restocking and tight intermediates lifted disperse dye prices to a peak.
disperse dyes about RMB 35,000/t (peak) (Faxian Gongchang 2026)
2024-2025
Weak textile exports and new capacity pushed prices down; Longsheng's average dye price fell 5.6%.
disperse about RMB 28,000/t (Jan 2024) to about 20,000 (end-2024) and 18,000 (Dec 2025); reactive about 22,000 (2024) and 21,000 (2025)
Early 2026
Intermediate prices jumped (reduction product from about RMB 25,000 to nearly 100,000/t in three months) and leaders raised prices.
disperse RMB 21,000/t (Feb 2026, +16.7%); Runtu disperse black RMB 26,000 to 40,000/t (Feb-Mar 2026); reactive about RMB 22,800/t (H1 2026)

What drives the cycle

Chinese environmental enforcement. Closures of intermediate plants create sudden shortages and price spikes; capacity replacement rules (2 for 1 for H acid) limit new supply.
Textile demand and exports. China's textile exports ($307 billion in 2025) and South Asian garment output set dye volumes.
Fibre mix. Polyester growth favours disperse dyes; cotton favours reactive and vat dyes.
Brand chemical rules. ZDHC MRSL 3.1 and REACH restrictions shift demand to compliant suppliers.
Trade remedies. Indian anti-dumping reviews on Chinese dyes and dyeing chemicals change import parity.
