Cargo and Container Shipping Basics

Successful international shipping requires a good understanding of cargo and container shipping basics.

When large cargo pieces have to be transported by sea, the best and most cost-effective way to transport them is through cargo and container shipping companies.

No matter if you are shipping for residential or commercial reasons, if you are interested in shipping large or high-volume loads internationally, the ideal fit is cargo or vessel shipping.  In most cases, these load are hauled via a diverse assortment of containers, each designed to carry specific types of items.

As a whole, cargo and container shipping companies deliver fast and cost-effective service for getting exactly what you need shipped overseas. For easy transportation they’re located along all 3 U.S. coasts, based on their target destinations.  These transport fleets also serve export companies, government agencies and private individuals.

Cargo and Container Shipping Basics

Cargo and container shipping companies are found at 3 ports locations throughout the United States – Pacific coast, Atlantic coast and the Mexican gulf.

Companies that have a more targeted destination will be located within a coastal area that is most proximal to where the ships end-up. For example, companies that ship cargo direct to the Caribbean, are usually found in coastal cities in Florida.

Transport companies have a variety of ship sizes and container styles that can carry virtually anything – including another ship. There are 3 specific kinds of cargo shipping that these firms engage in: vehicle shipping, vessel charters and general cargo shipping.

Vehicle Shipping

Vehicle shipping is how car manufacturers deliver their cars across the ocean. Many transportation companies specialize in fleet transport, and have specific protocols for safety when carrying vehicles. This service also includes individuals who are interested in relocating their vehicle(s) by transporting them overseas.

Vessel Charters

Vessel chartering is designed for those that require private, or large scale shipping services. The chartering of a vessel is basically a rental agreement. With this agreement the charterer agrees to employ a vessel from its owner. In these cases, it is usually the charterer that is the owner of the cargo, so to ship it, he or she will depend on others to move the cargo. In this situation, the hire money for this deal is known as the “freight” and is the final pay-out to the owner of the ship for the use of the vessel.

From an economic sense, this is an ideal move for a company shipping regularly, that is not interested in going to the expense of purchasing its own ship. A preferred route for start-up cargo shipping companies. Make sure to research which shipping company works best for your needs, price-point, and destination. For instance, for those looking to find a vessel chartering service that ships to the Caribbean, should look at shipping companies based in the Jacksonville, FL area.

General Cargo Shipping

Since general cargo shipping handles most of the typical shipping for most circumstances, it tends to be the service companies’ hang their hat on. A general cargo shipping service is employed when cargo shipping companies are hired by government agencies, other companies, or private individuals ship the agreed upon cargo internationally.  Most shipping agencies have easy to access pick-up/drop-off areas, as well as tracking and logistics devices as well as other advanced technology that helps to monitor every shipment while it is en-route.

Container Shipping Basics – Sizes

Typically, most shipping containers are around 8 feet wide. The main difference comes in the length and height of the unit. The most common and most popular diameters usually consist of a unit that is 8-ft. wide, 8-ft. 6-in. inches high, and between 48-ft. and 53-ft. lengths in most units. However, recent trends show that units known as “high-cube” containers are on the rise for cargo shipping. These containers usually hover around 9-ft. 6-in high, and come in variety of container length combinations.
