Onion is one of the most price-volatile crops in export trade. Understanding China's growing calendar and how stored stock meets year-round demand lets buyers lock in better average costs instead of chasing spot spikes.

The Chinese onion calendar and its price rhythms

Main open-field onions are harvested between June and September, with the heaviest volumes from Shandong, Gansu and Heilongjiang. Prices typically soften at peak harvest, then firm through winter as fresh supply thins and cold-store stock takes over. Greenhouses extend supply but carry a cost premium.

Why cold storage flattens the curve

Large export suppliers operate controlled-atmosphere stores that hold onions for many months with low sprout and weight loss. Buying during the post-harvest glut and storing lets both buyers and suppliers ride out winter price rises — the classic arbitrage window for institutional buyers.

Reading the signals before you commit

Planting acreage, weather during maturation, export demand from your own region and freight rates all move the price. Forward or seasonal contracts let you fix a volume and grade in advance. Hua Sheng shares monthly market notes and offers flexible spot, contract and storage-supported programs.
