The Yiwu International Trade City is busy ahead of the new school term. Orders are concentrating on shops handling stationery, schoolbags, art supplies and uniform trim, in what Chinese merchants call the 'back-to-school economy' — one of the year's peak stretches.

Yiwu's market runs on very thin per-item margins offset by volume. The school season suits that structure, since the same items are reordered in bulk.

Domestic and export demand overlap

Chinese term-start demand coincides with new-school-year orders elsewhere in the northern hemisphere. September openings in Europe and North America and second-term buying in Korea and Japan arrive at once, creating competition for container space.

A recent change is the growth of small, varied orders placed through livestream commerce. Wholesalers running their own broadcasts and taking single-unit orders has created logistics demand quite different from container-lot trade.

A shifting product mix

The mix is changing too. Paper notebooks and writing instruments are edging down as tablet stands, stylus accessories and study lighting grow — shifts in how students work, reflected directly on wholesale shelves.

Safety standards are another variable. The European Union and Korea have tightened limits on hazardous substances in children's products, and shipments without certification stall at customs.

For Chinese-heritage distributors in Korea

Shops handling stationery and sundries in Seoul's Daerim-dong and Incheon's Chinatown should confirm lead times on Yiwu shipments now. Dispatch queues lengthen and freight rates rise in peak season.

Checking KC certification requirements item by item matters as well; missing paperwork at customs means missing the season.
