What to Look for When Buying a Shipping Container

What to look for when buying a shipping container including condition, size, and quality

When considering purchasing a shipping container for storage, relocation, or conversion into a living space, understanding what to look for when buying a shipping container is crucial for making an informed decision. 

Shipping containers vary widely, from units crafted with durable Corten steel designed for international shipping and heavy cargo loads, to specialty containers with features like double doors or open tops. 

Several important factors can influence your choice, including size, condition, intended use, and an understanding of shipping container strength, which plays a major role in durability and long-term performance. 

This guide breaks down the essentials in a clear, easy-to-follow way to help you confidently choose the right shipping container for your needs.

When deciding what to look for when buying a shipping container, it’s important to evaluate a few key factors to ensure you get the best value and performance for your project. From size and type to condition and grading, each detail plays a role in long-term usability.

Selecting the right container type and size depends entirely on how you plan to use it, either for storage, transportation, or conversion.

Condition and grades to check when deciding what to look for when buying a shipping container

Another critical part of knowing what to look for when buying a shipping container is understanding container condition and grading. Containers are available in new, used, and refurbished options, each with its own advantages.

Container Conditions: What to Look for When Buying a Shipping Container

New One-Trip Containers

New one-trip containers are manufactured overseas and used only once to transport cargo. Minor dents or scratches may appear due to transit, but these containers are structurally sound and nearly new, making them a popular choice for long-term use.

Used Containers

Used containers typically served in shipping fleets for 5–15 years. Because they have already been depreciated, many buyers choose them as low cost shipping containers for storage or modification projects. 

While they may show visible wear such as rust spots, dents, or faded paint, they remain highly durable and functional for storage and transport.

Refurbished Containers

Refurbished containers start as used units that are wind- and water-tight. Each container is cleaned, repaired, primed, and repainted for a longer life and better look. This option offers a balance between cost and aesthetics.

Shipping Container Grades

IICL (IICL-6)

These containers meet strict inspection standards set by the Institute of International Container Lessors. They are approved for overseas shipping and are typically in excellent condition, commanding a higher price.

Wind and Water Tight (WWT)

WWT containers are sealed against leaks and ideal for storage. Cosmetic wear is common, but structural integrity remains intact.

Cargo Worthy (CW)

Cargo-worthy containers are certified for transport and feature a valid CSC plate. They may show signs of age but are safe for shipping goods.

As-Is Containers

As-is containers are heavily worn and may have structural issues such as holes or damaged flooring. These are best suited for non-critical projects where appearance and longevity are not priorities.
