Are you looking for a cost-effective storage solution or a durable container for transportation? Many buyers opt for used shipping containers for sale to save money while still getting a reliable unit. However, purchasing a used container requires careful inspection to ensure quality, durability, and safety.

Buying a damaged or low-quality container could lead to leaks, structural issues, or security risks. To help you make the right choice, this guide will walk you through the essential factors to check before purchasing a used shipping container.

1. Inspect the Exterior for Structural Damage

The first step in assessing a used shipping container is to check its exterior. Look for the following issues:

Dents and Warping – Minor dents are common, but deep dents can weaken the structure.
Rust and Corrosion – Surface rust is fixable, but deep corrosion can cause long-term damage.
Roof Condition – Walk around the container and inspect the roof for excessive rust, holes, or soft spots.

2. Check the Doors and Seals

A shipping container’s doors and seals play a crucial role in protecting its contents. Before purchasing, test the following:

Door Alignment – Open and close the doors to see if they align properly. Misaligned doors could indicate frame distortion.
Rubber Seals (Gaskets) – Check for cracks or gaps that could allow water to enter.
Locking Mechanisms – Ensure the locking bars and handles function smoothly to secure your container.

3. Look for Water Damage and Leaks

Leaks are one of the biggest concerns when buying a used shipping container. To check for leaks:

Step inside the container, close the doors, and look for any light leaks. If light passes through, water can too!
Inspect the flooring for mold, stains, or soft spots, which indicate water damage.
Examine the ceiling and walls for rust patches or signs of condensation buildup.

4. Examine the Interior for Pests and Contaminants

Used shipping containers may have been exposed to pests, chemicals, or hazardous materials. Before buying:

Look for insect nests, rodent droppings, or foul smells.
Check if the container was used for transporting chemicals or toxic substances.
If unsure, request a decontamination certificate from the seller.

5. Verify the Container’s Certification and Grading

Shipping containers are categorized based on their condition and usability. Some key grading terms include:

Cargo-Worthy (CW): Suitable for transportation with minimal repairs.
Wind & Watertight (WWT): No leaks but may have cosmetic damage.
As-Is: Sold in its current condition, often requiring repairs.

6. Compare Prices and Buy from a Trusted Seller

Once you’ve inspected the container, it’s time to choose a seller. Follow these tips:

Compare prices from multiple sellers before making a decision.
Check online reviews and ratings to ensure the seller has a good reputation.
Avoid deals that seem too good to be true—extremely low prices often indicate poor-quality units.
