H-Acid Price Surge Accelerates Dye Sourcing Cost Increases
Chinese ex-factory H-acid prices reached 200,000 yuan per ton, forcing dye producers to pass massive cost hikes to buyers.
Briefing
The ex-factory price of H-acid, the main intermediate in reactive and acid dyes, hit a record 200,000 yuan per metric ton following a price hike on September 19, 2026. This move is forcing global chemical and textile buyers to adjust procurement budgets as dye producers pass costs down the supply chain. Because H-acid makes up as much as 50 percent of reactive dye production costs and lacks viable chemical alternatives, downstream price increases are unavoidable.
Overall, intermediate prices have surged 400 percent since the start of 2026.
Context
Heading into the price spike, procurement teams were watching global chemical inventories fall while waiting for Chinese plants to resume full operations after seasonal shutdowns. The key question was whether regional intermediate supply would recover quickly enough to keep rising costs from spilling into downstream textile processing contracts ahead of the fourth-quarter peak.
Analysis
The price rally stems from constraints on both feedstock and production capacity. On the feedstock side, China placed export restrictions on sulfuric acid, while shipping routes through the Strait of Hormuz faced disruptions. On the manufacturing side, stricter domestic safety and environmental enforcement has shut non-compliant plants, capping effective annual capacity under 60,000 tons.
H-acid functions like flour in a bakery: with no substitute ingredient available, any spike in raw material costs immediately raises the cost of every finished dye product. Dye makers have little option but to pass the increase to textile mills. Zhejiang Longsheng, for example, raised its reactive brilliant blue ED-R price to 300,000 yuan per ton, shifting raw material surcharges straight to downstream finishers.
Suppliers are also shortening quote validity windows and insisting on immediate booking confirmations to lock in supply.
Parameters
- H-Acid Ex-Factory Price ~ 200,000 yuan per metric ton, the record price level established by Tianjin Yadong on September 19, 2026.
- H-Acid Annual Production Capacity ~ Under 60,000 metric tons, China’s compliant capacity ceiling due to stricter environmental enforcement.
- Raw Material Cost Share ~ 30 to 50 percent, the share of finished reactive dye production costs accounted for by H-acid.
- Reactive Dye Finished Price ~ 300,000 yuan per metric ton for reactive brilliant blue ED-R 150%, after a recent price increase of 50,000 yuan per metric ton.
- Year-to-Date Price Increase ~ 400 percent, rising from 40,000 yuan per metric ton at the beginning of 2026.
Outlook
Buyers should expect continued upward price pressure on finished reactive dyes in the coming weeks as higher feedstock costs filter into autumn contracts. Sourcing teams should monitor spot market prices for industrial sulfuric acid in East China, which serves as the key leading indicator for H-acid manufacturing costs and will signal if intermediate prices might ease before winter.
Verdict
Dye and textile buyers should lock in fourth-quarter volumes immediately to guard against further downstream price increases driven by the structural intermediate shortage.
