September 2025 data from SunSirs : domestic device output reached 89,000 metric tons, down 2.2% month-over-month, with capacity utilization at 77%. This follows August's 91,000 tons, reflecting seasonal softening in downstream textile demand amid ample inventories.

Zhejiang's 20D spandex at 28,500 RMB/ton and 40D at 24,000 RMB/ton—flat from early September but down 5-7% year-over-year. Cost-side support from raw materials like MDI remains mixed, with BDO up 3% on supply constraints. 

Total domestic capacity at 135+ million tons annually—up 9% YoY—led by expansions from Huafeng Chemical (32.5 million tons, plus 20 million under construction for 2026). Yet, profitability lags: gross margins hover at 0.5-1%, with smaller producers facing 800-1,200 RMB/ton losses. Downstream apparel retail grew 8.5% YoY, but athleisure demand (10-20% spandex blends) plateaus amid economic caution.

SunSirs forecast Q4 recovery: utilization to 82% on holiday peaks and "Belt and Road" exports.

As an integrated internet platform providing benchmark prices, on September 29, the benchmark price of spandex on SunSirs was 24,250.00 RMB/ton, the same as at the beginning of this month.
