ISO Dimensions of Shipping Containers and the Code ...
ISO containers are the perfect solution for shipping as their dimensions are governed by the International Standards Organization (ISO). These regulations enable ISO containers to utilize space optimally, regardless of the mode of transport chosen.

Height
Standard ISO containers measure 8 ft. 6 in., but various discrete heights ranging from 4 ft. to 9 ft. 6 in. are also available. Containers that possess a height of 9 ft. 6 in. are known as extended height or high cube containers, while those measuring 4 ft. or 4 ft. 6 in. may be referred to as half height containers.
Width
Most ISO containers are 8 ft. or 2,438 mm wide. Containers that exceed this width are classified into two additional categories. The letters C, D, E, and F denote containers that are wider than 2,438 mm but less than 2,500 mm. Meanwhile, those exceeding 2,500 mm are referred to with the letters L, M, N, and P.
Length
The most prevalent lengths for containers are 20 and 40 ft. Other available lengths encompass 24, 28, 44, 45, 46, 53, and 56 ft.
Coding, Identifying, and Marking
The identification standard for intermodal (shipping) containers is ISO:. This standardized system provides each container with a unique identifier, which can further be segmented into three components: an ISO (BIC) code, a size and type code, and additional optional markings.

ISO (BIC) Codes
The ISO (BIC) code specifies the container's owner, product group, and includes a unique serial number along with a check digit for identification purposes. The first three alpha characters represent the company or owner code, which is registered with the Bureau International des Containers et du Transport Intermodal (BIC) to ensure uniqueness. The product group U applies to all intermodal containers while J is designated for equipment attachments, and Z is used for the chassis or frames designed for intermodal containers. The serial number references an individual container and is cross-checked with the check digit.

Size and Type Codes
The size and type code consists of a four-character representation of the container's dimensions and type. The first character denotes the length, the second relates to height and width, and the last two characters specify the container's type.

What Are the Different Sizes and Types of Ocean Shipping ...
The information you need to choose the right size container for your international freight is outlined in this post. You'll understand what sorts of shipping containers are available, what their capacities are, and what size containers you ought to request for your freight after reading this post. You will find the details listed below. For example, you will learn about the standard dimensions of shipping containers (length, breadth, and height) and various dimensions for different types of shipments.
Main Types of Freight Container for International Shipping
There are no better dry freight containers than standards. They are suitable for handling loads that are either placed on pallets or skids or that are loose. In many cases, this is the only kind of container that a company shipping internationally will ever need, but you might consider using one of the following types of container if your cargo is particularly demanding:
Flat Rack Freight Container

Flat rack freight containers are large, horizontal metal frames secured to the decks of cargo ships with removable steel locks. They are used to transport oversized or overstuffed products. The typical height is around ten feet, and the container might stretch up to 60 feet or more.
High Cube Container
The height of a high cube container is approximately 6 inches higher than a standard dry container, making it a little more spacious. A full load in a high cube container may contain up to 76 cubic metres of freight, compared to 67 cubic metres in a standard box. It is nearly identical to a standard dry container. A 20-foot (6.25m) long high cube container has dimensions of 8'0" (2.44m) by 8'6" (2.59m) by 9'3" (2.82m), while a 21-foot (6.50m) long high cube container has dimensions of 8'0" (2.44m) by 10'0" (3.05m) by 11'5" (3.48m). A high cube container's height is set 6" higher than a standard ISO shipping container to allow for more volume inside, so if you get an extra 6" of height, you get 19% more cubic space.
Open Top Freight Container
For situations where you have a shipment that is too big for a standard dry container, but not big enough to warrant a high cube unit, you might be able to use an open top shipping container. Of course, the top of this kind of container is not really open, but is covered with a tarpaulin to keep out the elements. It may also be loaded and unloaded by crane. Although bulk containers or lift vans are popular, many customers demand additional features that are not always available.
Tunnel Container
A tunnel container is a dry freight container, used to transfer FCL and LCL cargo, in which the doors are at either end, making loading and unloading much simpler than a standard single-door unit. To expedite the loading and unloading of cargo, tunnel containers are ideal. The specialized locks and additional metal layer on an ISO shipping container make this a feasible option. Because certain products require higher-risk delivery methods, tunnel containers were designed to handle them.
Side Open (or Open Side) Shipping Container
Forklifts can load or unload items packed on pallets using open side units like tunnel containers. Instead of having doors at the ends, one entire side of the container is hinged in four places, providing access along the entire length of the unit. This type of container is perfect for when forklifts will load or unload goods.
Tank Containers
Tank containers are used to transport both non-hazardous and hazardous liquids and gases. They are made of steel or another durable material and are cylindrical in shape. So that they may stack with other container types on a cargo vessel's or container terminal's deck, they are identical in size and shape to standard containers. A lot of ocean container traffic is handled now by Oceanus' fleet of patented clamshell tank containers, one of every six tons of which is handled by Oceanus. The Oceanus tank container has 44 stanchion locations on three curved corrugated corner posts, each with stake pockets. The corrugated steel roof supports a corrugated steel sheet on which a corrugated corner post supports it from above by corrugated corner posts. The corrugated corner posts, which are spaced at regular intervals and connect the corrugated steel sheet, support the corrugated steel sheet from above by corrugated corner posts.
Refrigerated Containers (or Reefers)
These are identical to ordinary dry shipping containers, but have insulation and refrigerator units to keep the contents within a certain temperature range during transport and storage. As intermodal delivery systems became feasible, railways were able to transport food across the globe without losing nutritional value. New technology also made these containers more efficient and less hazardous than ever before. They are able to maintain food fresh for extended periods of time by maintaining a specific temperature (most frequently around -10 degrees Celsius) with cold-produced systems or cryogenic systems. To allow for easy loading and unloading, these containers usually have a large door on one end.
