What’s the Difference Between Shipping, Storage, Cargo and Conex Containers?
Shipping, Storage, Cargo and Conex Containers can all be used interchangeably and mean the same thing, however some subtle differences are worth noting.
Shipping containers are to be used for shipping and transportation over long distances including internationally.
Storage containers are to be used on site for storage. They can be slightly different with doors cut for easier access.
Cargo containers are to be used for freight and logistical purposes.

What’s the Difference Between New and Used Shipping Containers?
New shipping containers (also called “one-trip” containers) have only been used for one cargo shipment, and are in like-new, mint condition. If your project requires long term durability or a like-new, clean appearance, new containers are ideal.
Used shipping containers have been used for multiple cargo shipments and may have some cosmetic damage (dings, dents, rust, etc) but are still in very good, solid condition, and more budget friendly. Used containers are ideal for budget minded buyers, or projects with more short term needs.
