What is a Used 20 Foot Shipping Containers?
The used 20 Foot Shipping Containers are steel intermodal boxes, originally built to ISO standards for ocean freight, that have been retired from active cargo rotation and resold for storage or modification. After their shipping life — typically 10 to 15 years at sea — these containers remain structurally robust and are repurposed for on-site storage, mobile offices, workshops, and conversions.
The defining material is Corten steel, a weathering alloy that develops a stable rust-like surface layer. That layer slows further corrosion, which is why a properly graded used container stays wind- and watertight long after retirement from freight duty.

Benefits of Buying a Used 20ft Shipping Container
Buying a used 20ft shipping container offers numerous advantages, making it a wise choice for many. Here are some key benefits:
Cost-Effective
Used shipping containers are a budget-friendly option. New containers can be pricey, but opting for a used one can save you a significant amount of money. Many customers find that the cost is much lower than expected when they request a quote.
Eco-Friendly
Repurposing a used 20ft shipping container is an environmentally friendly choice. By giving a second life to these containers, you reduce the demand for new materials and minimize waste. This practice aligns with sustainable living and helps conserve natural resources.
Versatile
The versatility of a used 20ft shipping container is best. You can transform it into a storage unit, office, or even a home. Its adaptability makes it a popular choice for various applications:
- Storage: Ideal for storing tools, equipment, or personal belongings.
- Workspaces: Perfect for creating a mobile office or workshop.
- Living Spaces: Can be converted into a cozy home or guest house.
Durable
Made from Corten steel, these containers are built to withstand harsh environments. They are wind and water-tight, ensuring the contents remain safe and dry. The durability of these containers means they can last for many years, even with minimal maintenance.
In conclusion, purchasing a used 20ft shipping container is a smart investment. It’s economical, eco-friendly, versatile, and durable, making it a practical solution for various needs. Whether you’re looking for storage or a creative living space, these containers offer endless possibilities.
How Much Does an Empty 20 Foot Shipping Container Weigh?
An empty (tare) 20ft shipping container weighs approximately 4,800–5,050 lbs (2,180–2,290 kg). The exact figure is stamped on the container’s door (the “TARE” marking) and varies slightly by manufacturer and steel gauge.
Two related numbers matter for planning:
- Max payload: ≈ 47,900 lbs (21,700 kg) — the most weight the container is rated to hold.
- Max gross weight: ≈ 52,900 lbs (24,000 kg) — payload plus the container itself.
The tare weight is the figure that affects delivery: a tilt-bed truck needs firm, level ground and adequate clearance to set down a 5,000-lb steel box safely.
The Four Used-Container Condition Grades, Explained
Grade is the single most useful word in a used-container listing. It tells you the wear level and whether the unit is sealed against weather. Always confirm the grade in writing and request dated photos.
| Grade | Meaning | Best for |
| IICL | Inspected to the Institute of International Container Lessors standards, the cleanest tier | Resale, certified shipping, premium conversions |
| Cargo Worthy (CW) | Certified structurally sound and sea-ready | Export, long-term outdoor storage, modifications |
| Wind & Water Tight (WWT) | Sealed and dry, but with cosmetic dents and surface rust | On-site storage where appearance is secondary |
| As-Is | Sold without a watertight guarantee | Salvage, parts, low-cost non-critical use |
Factors to Consider When Buying Used 20 Foot Shipping Containers
When purchasing a used 20ft shipping container, several factors can influence your decision. Understanding these aspects can help ensure you make a wise investment.
Condition
The condition of a used container is crucial. Containers are categorized by their state, such as IICL, CW, or WWT. Each has different levels of wear and tear. New IICL and Used IICL containers have few dents and minimal rust, making them ideal for shipping. On the other hand, Used WWT containers may have more dents and surface rust but are still wind and water-tight, perfect for storage. Always inspect or request detailed photos to assess the container’s condition before purchase.
Price
The price of a used 20ft shipping container can vary based on its condition, type, and location. While new containers can start around $3,000, used ones are more affordable, with prices beginning at approximately $2,475. It’s essential to compare prices from different sellers to ensure you’re getting a fair deal. Some sellers, like Aztec Container, offer transparent pricing, allowing you to budget effectively.
Modifications
One of the exciting aspects of buying a used 20ft shipping container is the potential for customization. You can modify these containers to suit your needs, whether you want to add windows, doors, or insulation. While some suppliers do not offer customization, you can hire professionals to make these changes post-purchase. Modifications can add to the overall cost, so factor this into your budget.
Considering these factors will help you choose the right used 20ft shipping container for your needs. Once you’ve assessed these elements, you can confidently move on to explore the popular uses for these versatile containers.
What are the 20 Foot Shipping Containers Used For?
A used 20ft container suits any application needing secure, weatherproof, movable steel space. Common uses, each viable straight from the yard or after light modification:
- On-site storage: tools, equipment, inventory, and seasonal stock at homes, farms, and job sites. The most common use by volume.
- Mobile offices: insulated and fitted with power and a walk-in door, a 20ft unit becomes a portable office.
- Workshops: a lockable, dry base for trades and hobbyists.
- Refrigerated storage: an insulated or refrigerated unit handles temperature-sensitive goods.
- Pop-up retail and concessions: durable, brandable, and quick to relocate; see container concession stands.
- Container conversions: the structural shell for tiny homes, studios, and modular builds.
How Do You Inspect Used 20 Foot Shipping Containers Before Buying?
Use this five-point checklist whether inspecting in person or reviewing seller photos. Each point can be verified independently.
- Roof and panels: Look for holes, deep dents, or rust perforations. Standing water marks on the roof can signal pooling and future leaks.
- Doors and gaskets: Doors should swing and lock without forcing. Closed, no daylight should show through the seals. Damaged gaskets are the most common leak point.
- Floor: The marine plywood floor should be solid underfoot, not soft, spongy, or delaminating. Check for prior water damage.
- Frame and corner castings: The corner posts and rails carry the structural load and the lifting points. Reject visible bending, warping, or cracked welds.
- Rust depth: Surface rust is normal on used units and is cosmetic. Flaking, scaling, or rust that has eaten through steel is structural and disqualifying.
Field test for watertightness: step inside, close the doors, and look for any pinpoints of daylight. Light in means water in.
Cost of Used 20 Foot Shipping Containers
When you’re in the market for a used 20ft shipping container, understanding the cost is key. Prices can vary, but let’s break it down simply.
Price Range
Typically, a used 20ft shipping container starts at around $1,500 and can go up to $2,900. The price depends on factors like the container’s condition and the local market. For instance, a container labeled “Cargo Worthy” might be pricier due to its better condition.
Market Trends
Global events can impact prices. For example, disruptions like shipping route changes have temporarily increased costs. Recently, market analysts have noted a rise in demand for containers, which has driven up prices. However, as supply chains stabilize, prices are expected to level out.
Regional Differences
Prices also vary by location. In areas with high demand but low supply, like certain parts of Texas, you might see higher prices. Conversely, regions with more supply might offer more competitive pricing. It’s always a good idea to compare prices across different regions to find the best deal.
Understanding these factors will help you make an informed decision when purchasing a used 20ft shipping container. Next, we’ll discuss where you can buy these containers and the best places to look.
New vs. Used 20 Foot Shipping Containers: Which Should You Buy?
| Factor | New (one-trip) | Used (WWT / CW) |
| Price | Higher | Lower — often the deciding factor |
| Appearance | Near-pristine | Cosmetic dents, surface rust |
| Structural integrity | Excellent | Excellent when CW/WWT graded |
| Sustainability | New steel produced | Repurposes existing steel |
| Best for | Branded retail, premium conversions | Storage, workshops, budget projects |
For the majority of storage and workshop buyers, a Cargo Worthy Shipping Container or Wind & Water Tight used unit delivers new-container function at a materially lower price, while reusing existing steel rather than commissioning new.
Where to Buy Used 20ft Shipping Containers?
So, you’re ready to buy a used 20ft shipping container. But where should you start looking? Let’s explore some options.
Local Dealers
Local dealers are a popular choice for many buyers. They often have a range of containers available for immediate inspection.

Plus, buying locally can reduce delivery costs.
Online Marketplaces
The internet offers a wealth of options. Websites like Shipped.com list containers from various sellers. You can compare prices and features easily. However, be cautious. Always verify the seller’s reputation and ask for detailed photos of the container. While you might find good deals, shipping costs can add up, especially if the seller is far away.

How much does an empty 20ft shipping container weigh?

Are used shipping container prices going up or down?
Used container prices track steel costs and ocean-freight supply. They rise when shipping disruptions tighten supply and ease when supply chains normalize. Prices also vary by region: inland markets far from ports typically cost more per unit than coastal hubs because of added trucking. Comparing landed quotes (container plus delivery) is the reliable way to gauge the current market.
What does “Cargo Worthy” mean?
Cargo Worthy (CW) means a container has been inspected and certified as structurally sound and sea-ready, with only light wear. It is the standard grade for export, long-term outdoor storage, and modifications.
How long does a used 20ft container last?
A well-graded used container can remain serviceable for decades with minimal maintenance, because Corten steel forms a protective surface layer that slows corrosion. Keeping it on a level, drained base and treating any deep rust early extends its life further.
Can a used 20ft container be modified?
Yes. Common modifications include adding personnel (walk-in) doors, windows, roll-up doors, vents, electrical, and insulation. Specifying these at purchase is usually cheaper than retrofitting later.
