Reserve Cotton Floor Price Falls for Half a Month, How Textile Mills Should Time Stockpiling

At 16,480 yuan per ton, the floor price for grade 3128B reserve cotton in the fourth week (Aug 10-14) of 2026 sales is not an isolated number. Since sales started on July 20, the weekly floor price has declined for consecutive weeks, with a cumulative drop exceeding 200 yuan. For textile mills, this is more than a price signal—it is a decision signal.

Price Decline Reflects Loose Supply-Demand

The adjustment mechanism is straightforward: the benchmark is grade 3128B, updated weekly, and converted to specific lots using quality differential tables from the China Cotton Association. The fourth-week floor price of 16,480 yuan/ton is about 1.3% lower than the first week (around 16,700 yuan). The consecutive declines reflect a repricing of the annual supply-demand balance, with new crop expectations, import arrivals, and downstream order visibility all converging.

For buyers, a lower floor price means lower actual auction costs. But the floor is just a starting point; final prices are set by bidding. Recent auctions show clear premiums for high-grade cotton and occasional failures for low grades, indicating structural divergence rather than a one-way bearish view.

Transmission: A Window for Mill Profit Repair

Reserve cotton pricing anchors with the spot market. When the reserve floor is lower than spot, mills tend to increase bidding, lowering procurement costs. With spot for 3128B around 16,900 yuan, the reserve floor is about 420 yuan lower, translating to 500-600 yuan lower cost per ton of yarn (with a 1.1-1.2 cotton usage factor). For mills with thin margins, this represents a 2-3 percentage point gross margin improvement.

But the window won't stay open forever. Historically, reserve sales end by late September, and new crop arrives in October. If mills delay restocking, they risk two things: high-quality lots being snapped up, and new crop prices opening higher. Therefore, mid-August to early September is the critical restocking period.

Regional and Structural Strategies

Regionally, Xinjiang mills, benefiting from transport subsidies, show limited interest in inland reserve cotton; while mills in Shandong, Henan, and Hubei, with convenient pickup, are more active. Structurally, high-count yarn mills should lock high-grade reserve cotton to maintain quality consistency; low-count or blended yarn producers can consider mid-to-low grades, but must verify downstream tolerance for strength, micronaire, etc.

Also, the weekly price adjustment means price risk is borne by the enterprise. Mills should link reserve bidding with forward procurement plans, avoiding one-shot heavy positions, and instead build in batches to smooth cost fluctuations.

Practical Recommendations

For Procurement Managers - Participate in early-week auctions, selecting lots whose certified grade matches your needs; avoid blindly chasing high grades. - Calculate actual landed cost (including delivery and transport fees) using quality differential tables; be cautious if the gap with spot is less than 200 yuan/ton. - Monitor daily lot quality indicators to filter best value via differential tables.

For Foreign Trade Firms - For orders with locked export yarn prices, use the current floor price decline to lock raw material costs and enhance pricing competitiveness. - Watch RMB exchange rate and imported cotton prices; if imported cotton is cheaper than reserve equivalent, adjust procurement mix. - When signing long-term contracts with mills, reference the reserve floor as a price adjustment benchmark to reduce default risk from cotton price volatility.
