China Dye Stocks Surge as H-Acid Prices Double; Shanshui Tech Notches Third Limit-Up

The rally is being framed by the companies themselves as cost-push, not demand-pull, which matters: H-acid doubling feeds straight into reactive-dye input costs, and the limit-up moves in Shanshui and Yabang are pricing that pass-through before any evidence of volume recovery. The distinction separates a margin story from a genuine textile-cycle upturn, and the peak-season stocking wave is seasonal by nature. Whether H-acid holds near Yadong Longxing's September quote, and whether downstream buyers absorb higher dye prices rather than balking, is the open question.
