The number 16,341 yuan per ton is not surprising to anyone in the cotton trade at the end of September, yet it is enough to force yarn mill owners to recalculate their cotton blending budgets. China Reserve Cotton Management Co. set the sales floor price for week 11 of 2026 at 16,341 yuan per ton, equivalent to standard grade 3128B, effective only for September 28-29. The reserve release has been running since late July, but the new crop has yet to arrive in volume, leaving the market in a pricing-sensitive transition period.
How the Floor Price Is Calculated
The reserve cotton floor price is not a flat rate. It is anchored to the standard grade 3128B price and then adjusted batch by batch according to cotton notarization inspection results and the domestic cotton quality differential table published by the China Cotton Association. This means that within the same week, actual floor prices for different batches can vary by several hundred yuan.
For spinning mills, the core variable in this pricing mechanism is the quality premium or discount. Once indicators such as staple length, breaking strength, and micronaire deviate from the standard grade, the premium or discount directly changes the delivered cost. If procurement staff budget only against the 16,341 yuan figure, they may be forced to bid higher during the auction.
The Transitional Logic Before New Crop Arrival
The pace of reserve cotton release is closely tied to the Xinjiang harvest schedule. Late September marks the window when hand-picked and machine-picked cotton overlap, ginning mills have not yet fully opened their buying stations, and available spot supply is limited. Reserve cotton serves as transitional supply during this gap, smoothing price volatility.
But transitional supply does not mean cheap supply. A floor price of 16,341 yuan sits at a relatively high level within the current yarn pricing system. The immediate profit margin for 32-count pure cotton yarn is further compressed, and some small and medium-sized mills may shift to blended yarn or reduce operating rates.
Transmission Through the Supply Chain
From cotton to grey fabric to apparel, cost transmission involves a clear time lag. A high reserve floor price first affects yarn quotations, then fabric and garment prices. If export-oriented companies lock in forward quotes based on current cotton prices, they need to guard against customer pressure for price cuts should cotton prices fall after the new crop arrives.
Another signal worth watching is the domestic-international cotton price spread. If the domestic reserve floor price remains above international cotton prices, imported yarn becomes more competitive, and domestic yarn may lose market share in the low-count segment. For export-oriented mills, this is a variable that requires advance planning.
For Buyers - Verify quality indicators of target batches before auction and calculate the actual delivered price using the differential table, rather than budgeting solely on the floor price - Keep inventory low before the new crop arrives, purchase reserve cotton in batches to avoid concentrated price-locking risk - Monitor the domestic-international price spread and adjust the procurement mix between domestic and imported yarn accordingly
For Mills - Incorporate quality premiums and discounts into cotton blending cost calculations, and reassess blending ratios to balance raw material expenses - Communicate with new crop suppliers in advance on expected opening prices and lock in a portion of forward raw materials - If yarn margins remain under pressure, consider adjusting operating schedules and prioritizing high-value-added orders
The reserve cotton floor price is only a starting point. The real pricing power game begins after the new crop buying stations open. For all players in the supply chain, this two-day window at the end of September is more like a preview of the cost baseline for the new year.
