"Process of Shipment" vs "Process of Shipping"

Which one of the two expressions "Process of shipment" and "Process of shipping" seem correct? The NyTimes seems to be using both of them:

Solution 1:

Shipment, in the Oxford English Dictionary’s definition, can mean ‘the act of shipping (goods or commodities) for transportation’ and shipping can mean ‘the action of putting persons or things on board ship or transporting them by ship’. So not much difference, but since both imply the act or action of moving stuff around on the sea, the question should perhaps be whether the word process is required as well.

Solution 2:

Shipping -> business or act of sending something

Shipment -> cargo or freight

shipping is the process, shipment is the result.

You are shipping the package to someone, when you finish, the shipment will be ready to transport
