When you start pricing up a 20ft container, you will quickly see two very different options: one-trip containers that look almost brand new, and used containers that cost less but show a few more signs of life. Both can be the right choice. This guide explains what each term actually means, how they compare and which one suits your plans.
What Is a One-Trip Container?
A one-trip container is a new-build shipping container that has been used to carry cargo once, usually on its first voyage from the factory in Asia to Europe. After unloading, it is sold on rather than sent back empty. Because it has only made a single loaded journey, it is built and treated as new: the steel, floor, seals and doors are all in first-use condition. You may see a few light scuffs or marks from loading, but nothing structural.
That is why one-trip containers are so popular. You get near-new quality without paying the full price of a container that has never left the factory.
What Is a Used Container?
A used container has spent several years or more in shipping service. Expect surface rust, small dents, patched paint and a floor that has seen some wear. Used containers are graded by condition, and the most important grade for buyers is wind and watertight (WWT). A WWT container is structurally sound and keeps the weather out, even if it is not cosmetically perfect. Unless stated otherwise, every used container we sell is graded WWT.
One-Trip vs Used at a Glance
| One-trip 20ft | Used 20ft (WWT) | |
|---|---|---|
| Age | Typically under a year | Usually 8 to 15 years |
| Appearance | Near-new, minor marks | Visible wear, dents and rust spots |
| Paint | Original factory finish | Often faded or patched |
| Floor | Clean, like new | Marked and worn but sound |
| Weatherproof | Yes | Yes (WWT graded) |
| Expected lifespan | 25 years or more with basic care | 10 to 15 years or more, depending on condition |
| Price | Higher | Lower |
When a One-Trip Container Makes Sense
- It will be on show. In a garden, at a shop front or on a customer-facing site, a clean container looks far better.
- You are converting it. Offices, workshops and garden studios are much easier to fit out in a straight, clean box. See our guide to 20ft office containers.
- You want it to last. A one-trip unit gives you the full working life of the container.
- You are storing valuable or delicate items. Fresh seals and a clean floor reduce the risk of damp and dirt.
Examples from our range include the 20ft one-trip container in Window Grey and the 20ft wind and watertight one-trip container in white.
When a Used Container Makes Sense
- Budget matters most. A used unit gives you secure, dry space for the lowest price.
- Appearance does not. On farms, building sites and industrial yards, a few dents make no difference.
- It is for straightforward storage. Tools, machinery, feed and materials are all well suited to a used container.
- It is a temporary need. If you only need it for a project or a couple of years, there is little reason to pay for new.
Our used 20ft standard container (IICL5 grade) is a good example of a sound, economical storage unit.
What to Check Before You Buy
Whichever you choose, it pays to check the following, either in person at our Essex yard or with photos before delivery:
- The doors open and close smoothly and the rubber seals are intact.
- There are no holes in the roof or walls. Stand inside with the doors shut; you should see no daylight.
- The floor is firm with no soft or rotten patches.
- The corner castings and frame are straight and undamaged.
- The locking bars and handles work properly.
Our Verdict
If the container will be seen, converted or kept for many years, a one-trip 20ft container is usually worth the extra outlay. If you need secure, dry storage at the lowest cost, a used wind and watertight container is hard to beat. For the bigger picture on sizes and types, read our complete 20ft shipping container guide.
