Chinamax

The standard was originally developed to carry very large loads of iron ore to China from Brazilian port facilities operated by mineral firm Vale.

[1][2] Correspondingly, harbours and other infrastructure that are "Chinamax-compatible" are those at which such ships can readily dock.

[1][2] 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.
