Chinamax

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 draft, beam and length overall. An example of ships of this size is the "Valemax" bulk carriers.
The standard was originally developed to carry very large loads of iron ore to China from Brazilian port facilities operated by mineral firm Vale.
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.
In container shipping, recent classes intended for trade with China have all focused on a ~400 meter length, which deep water container terminals can cater for.
