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 multiple harbours at maximum capacity. Inversely, harbours and other infrastructure that are "Chinamax-compatible" can receive such ships economically, i.e. all harbours accept the same maximum measurements: Maximum 24 m (79 ft) draft, 65 m (213 ft) beam and 360 m (1,180 ft) length overall.

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.

The name is derived from the massive dry-bulk (ore) shipments to China from multiple locations around the world.

In contrast to Suezmax and Panamax, Chinamax is not determined by locks or channels. It is aimed at port provisions.
