The disperse dye supply chain is undergoing a structural cost reconstruction driven by intermediate price surges. Starting July 21, 2026, Zhejiang Longsheng and Runtu jointly raised disperse dye prices, with disperse black 300% series up 3,000 yuan per ton and all other colors up 1,000 yuan per ton. This round of price hikes is not an isolated event but a delayed reflection of sustained intermediate cost inflation since late 2025.
The Logic of Cost Transmission
The fundamental driver is two irreplaceable intermediates. Reducing agent, essential for disperse black and blue dyes, jumped from 25,000 yuan/ton in late 2025 to 70,000-100,000 yuan/ton by March 2026, reaching 120,000 yuan/ton in July—a nearly 300% increase. Another key intermediate, p-nitrochlorobenzene, surged from 3,500-3,700 yuan/ton a year ago to 14,000 yuan/ton currently, also up nearly 300%.
Supply-side tightening is the root cause. Intermediate production is high-risk and heavily regulated; only 7-8 plants nationwide produce stably. Environmental inspections have forced multiple plants to shut for maintenance, tightening supply. New capacity approvals and construction take time, leaving a gap that cannot be quickly filled. China Dyeing & Printing Industry Association data shows Q1 2026 profits of 2,036 large-scale dyeing firms fell 16.1% year-on-year, with 43.96% operating at a loss.
Keqiao's Squeeze
Keqiao, as China's largest chemical fiber fabric base, relies heavily on disperse dyes for polyester and polyester-spandex fabrics. Black and blue colors account for over half of local mill capacity, making the 3,000 yuan/ton rise in disperse black the most direct blow. A medium-sized mill sees monthly dye procurement costs increase by hundreds of thousands of yuan.
Compounding this, steam prices have risen twice this year, and new peak-valley electricity tariffs in Zhejiang took effect in July, raising costs for energy-intensive processes like setting and dyeing. Dye, energy, auxiliaries, and labor costs are all rising simultaneously, compressing margins. Meanwhile, Keqiao Textile City is in its traditional off-season: long orders of 10,000 meters have shrunk, replaced by small lots of hundreds of meters and color-matching reorders. Frequent machine cleaning and idle runs have increased dyeing losses by 10%-20% year-on-year.
Market pricing is transparent, giving traders and large buyers strong bargaining power. Mills that raise dyeing fees risk losing orders to cheaper competitors or even to Southeast Asian capacity. Many Keqiao mill owners say they have to absorb cost increases to retain orders, operating at thin or negative margins, while shutting down means bearing equipment depreciation and fixed labor costs.
Demand-Side Support and Structural Divergence
Textile exports show resilience: from January to May 2026, China's textile and apparel exports reached $116.7 billion, up 0.1% year-on-year, providing basic support for dye demand. However, incremental orders are mostly low-cost standard fabrics, unable to support higher dyeing fees. Fabric traders report that downstream apparel brands are aggressively pushing for lower prices, and fabric price adjustments lag behind dye cost increases, squeezing trading margins.
From intermediate spikes to coordinated dye price hikes, this cost-up cycle is likely to persist. As a bellwether for China's textile industry, Keqiao's entire chain—weaving, dyeing, and trading—faces a deep reshuffle. Whether Q3 peak season demand can ease the cost burden remains uncertain, and the industry must keep watching upstream intermediate supply.
