Recent auction activity and growing substitution options are constraining corn pricing and forcing Chinese feed mills into just-in-time buying. Shandong’s June 9 import corn auction offered 203,000 tonnes at starting bids of RMB 2,100–2,330/ton and sold 190,000 tonnes (94% rate) with an average premium of RMB 56/ton. Import auctions have continued on a weekly ~200,000-tonne rhythm (June 5: 155,000 t, 92% sold; June 9: 203,000 t, 94% sold; June 16: 201,000 t including 22,000 t Ukrainian non-GM), signalling a steady supply window that mills factor into procurement decisions.

On the demand side, feed formulators are substituting heavily: sprouted wheat (2220–2400 RMB/ton landed) is being used at 25–30% inclusion because it is often ~RMB 100/ton cheaper than nearby North China corn purchase prices (around 2388–2410 RMB/ton) and offers higher protein. A May 29 paddy rice auction (1 million t offered) cleared only 63.4% with minimal premium, bringing brown-rice adjusted port costs close enough to corn to act as an alternative when the price gap widens. Regional dynamics split further: northern ports have policy support and purchases (Jinzhou/Bayuquan procurement ~2320–2340 RMB/ton), while southern mills face abundant imported sorghum/barley and corn that cap upside.

Operationally, arrival flows drive short-term moves — vehicle arrivals in Shandong swung from lows near 37 trucks to about 670 on June 16, briefly easing bids — and mills report corn inventories around 27–28 days of safety. Deep-processing run rates are near 58% entering maintenance. Futures (DCE corn C2607) are trading in the RMB 2,324–2,332/ton band with resistance near 2,350–2,370 and support at 2,290–2,300, reflecting a market trapped between trade-held cost floors and substitution-driven ceilings.
