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.
