New Reserve Cotton Sales Rules: Spinning Mills Get Self-Use Purchase Window, Market Floor Price Mechanism Introduces Domestic-Foreign Linkage

A new variable is emerging in the raw material supply landscape for the cotton textile industry. Starting July 20, 2026, China Reserve Cotton Management Co., Ltd. will launch a new round of central reserve cotton auction sales, strictly limited to textile mills and explicitly prohibiting resale. This policy adjustment means that in the coming weeks, domestic cotton spinning mills will gain a relatively closed procurement window, while the floor price calculation mechanism introduces a 50/50 weighting linkage between domestic and international spot indices for the first time.

Background: From Reserve to Precision Release

This reserve cotton sale is not an isolated event. According to the announcement, sales will be conducted on each national working day, with daily auction volumes dynamically arranged based on market conditions. The floor price will be adjusted weekly, calculated as: current week floor price = 50% × arithmetic average of domestic cotton spot price index over the previous week + 50% × arithmetic average of international cotton spot price index over the previous week. The domestic index is the average of the China Cotton Price Index (3128B grade) and the National Cotton Price Index (3128B grade), while the international index uses the Cotlook A index, converted to RMB including tariff and VAT.

Notably, participation is restricted to textile mills, and purchased reserve cotton must be used by the bidding enterprise itself, with resale strictly prohibited. Violators will be barred from future reserve cotton transactions. This restriction, rarely seen in previous reserve releases, signals a precision-targeting approach to prevent speculative hoarding and ensure reserve cotton flows directly to production.

Industry Impact: Narrowing Spread and Reshaping Procurement Rhythm

The new floor price mechanism will profoundly affect mill procurement decisions. Previously, reserve sale floor prices relied more on domestic references, with limited international linkage. The new formula gives equal weight to domestic and international prices, meaning when international prices are lower, the floor price will be dragged down, reducing overall procurement costs; conversely, if international prices rise, the floor price will follow. For mills, this creates a semi-marketized pricing anchor, partially hedging price volatility during the procurement window.

From an industry transmission perspective, this mechanism will directly benefit large mills, especially those with import quotas and the flexibility to switch between domestic and international cotton. They can compare reserve auction prices with imported cotton costs using the transparent formula. For smaller mills, while they gain bidding access, they must closely monitor weekly adjustments to avoid concentrated purchases at high prices.

Moreover, the strict self-use restriction and resale ban will effectively curb past practices of "quota flipping" during reserve releases. This helps stabilize real supply-demand signals in the spot market, reducing price distortions from speculative inventories. In the initial release phase, spot market trading activity is expected to decline as some demand shifts to the reserve auction channel.

Practical Recommendations

For Procurement Teams - Pre-calculate monthly mill consumption and plan bidding batches to avoid concentrated capital pressure from consecutive auctions. - Monitor weekly floor price adjustments, typically announced on Thursdays or Fridays, and assess cost advantages by comparing domestic-international price spreads. - Ensure the enterprise's unified social credit code matches its textile mill qualification to avoid invalid bids.

For Foreign Trade Enterprises - This reserve sale is limited to domestic mills; foreign trade firms needing raw materials should focus on the import cotton market and use spread fluctuations for hedging. - Note that the floor price formula uses the exchange rate from the third Wednesday of the previous month; foreign trade firms can anticipate its impact and lock in settlement costs early. - If the foreign trade company operates its own spinning segment, verify whether it qualifies as a "textile mill" to participate in bidding and reduce raw material procurement costs.
