Why does Xinjiang dominate China's lint cotton output and what does that mean for buyers?
Xinjiang now accounts for roughly 92.8% of China's lint cotton output, and its yields are the reason. National lint yield reached 134.3 kg/mu in 2023, but Xinjiang alone hit 143.9 kg/mu while Jiangxi managed only 75.6 kg/mu on the same varieties. The shift is technological, not just geographic. Mulch film raises early-season soil temperatures so cotton matures before autumn frost, and the mulch enabled the world's most water-efficient drip irrigation, cutting water use another 30% versus standard drip. Xinjiang is also China's only long-staple base, the premium fiber for high-end fabric. Buyers should treat Xinjiang weather, acreage guidance and water policy as the core supply signals for Chinese lint cotton.
