China Shipping Container Lines Co., the nation’s second-biggest cargo-box carrier, plans to impose an “emergency equipment surcharge” of $400 per forty-foot box on transpacific shipments next month because of a global shortage of containers.

AP Moller-Maersk A/S, the world’s largest container line, has forecast an “unprecedented” shortage of cargo boxes because of a surge in shipping demand amid the global economic revival. Supplies of new containers plunged worldwide last year as shipping lines pared orders amid a trade slump.
