Shipped per s.s意思
"Shipped per s.s." is a term commonly used in shipping and logistics to indicate that the goods have been shipped by sea on a steamship or steamer. The abbreviation "s.s." stands for "steamship" and is used to specify the mode of transport as being by sea, using a vessel powered by steam.
In the context of historical or formal documents, "s.s." might be used to refer to a specific steamship or to indicate that the shipment was made by a steam-powered vessel in general. However, in modern usage, the term "steamship" is less common, and the mode of transport would more likely be specified as "vessel" or "ship" without the need for the "s.s." abbreviation.
It's important to note that the term "s.s." can also be used in a more general sense to mean "ship" or "steamer," depending on the context. In some cases, it might be used to refer to any type of ship, not just steam-powered ones.
