Comparison of bounding box of Chinamax with some other ship sizes in isometric view.

Chinamax is a standard of ship measurements that allow conforming ships to use various harbours when fully laden, the maximum size of such a ship being 24 m (79 ft) draft, 65 m (213 ft) beam and 360 m (1,180 ft) length overall.

Correspondingly, harbours and other infrastructure that are "Chinamax-compatible" are those at which such ships can readily dock. Unlike Suezmax and Panamax, Chinamax is not determined by locks or channels, or bridges—the Chinamax standard is aimed at port provisions and the name is derived from the massive dry-bulk (ore) shipments that China receives from around the globe.


The deadweight tonnage of Chinamax vessels is 380,000–400,000 DWT. The Brazilian iron ore company Vale is currently buying a fleet of 35 very large ore carriers (VLOC) with a deadweight tonnage within this range, referred to as the Valemax vessels.[1] Berge Bulk has also ordered four ships of similar size.
