When the domestic cotton spot price index is weighted together with the international market index, the dynamically adjusted weekly floor price for reserve cotton sales is opening a self-use procurement window for textile mills. On July 14, 2026, China Reserve Cotton Management Co., Ltd. announced that starting July 20, part of the central reserve cotton will be sold through public bidding on the National Cotton Trading Market every working day. The core variable: the floor price is calculated by weighting the domestic cotton spot price index (average of China Cotton Index and National Cotton Price Index, grade 3128B) and the Cotlook A Index at 50% each, adjusted weekly. This means buyers cannot lock in long-term low prices nor bear unilateral upside risk—the pricing mechanism itself becomes a market sentiment stabilizer.
Pricing Mechanism and Market Signals
The formula behind the reserve cotton floor price reveals policy intent: to align with international prices while considering domestic industry affordability. Specifically, the international portion is converted into a landed cost: multiply the Cotlook A Index by the exchange rate, then add 1% tariff and 9% VAT. The domestic portion directly averages two authoritative indices. The 50/50 weighting, set against the backdrop of tight global supply-demand and volatile China-US price spreads in 2026, essentially provides mills with a 'middle ground' procurement benchmark. For buyers, the weekly update means they must closely track price movements in both markets or risk missing bidding windows.
Industry Impact: Self-Use Rules Reshape Procurement Behavior
The strictest constraint is on bidding eligibility and end use. Only textile mills can participate, and purchased cotton must be for self-use only—the unified social credit code or tax registration number must match, with resale prohibited. Violators face disqualification from future reserve cotton transactions. This clause directly blocks trader arbitrage, locking reserve cotton to real production demand. For small and medium-sized spinning mills, this means pre-calculating self-use volumes, capital turnover cycles, and inventory costs, because once cotton is won, it can neither be resold nor transferred between enterprises. From the industry transmission perspective, reserve cotton entering the market will increase supply, putting short-term downward pressure on spot prices. However, since the floor price follows the market, actual transaction prices are likely to stay close to the floor range, minimizing the risk of a price crash.
Regional and Category Focus: Grade 3128B as Pricing Anchor
The announcement appendix specifies that the floor price corresponds to standard grade 3128B (bright white, 28mm length, Micronaire B). This is one of the most commonly used raw material grades in domestic mills, covering mainstream needs from ring spinning to open-end spinning. Regionally, the Xinjiang cotton region, as a major high-quality domestic producer, will influence the reserve floor price indirectly through the China Cotton Index. Spinning mills in traditional textile clusters like Shandong, Henan, and Jiangsu may gain logistics advantages by participating in nearby bidding. Notably, quality grade differentials follow the China Cotton Association's published differential table, meaning actual transaction prices will float based on the cotton's specific grade—premiums for higher-grade cotton still exist.
