A one trip 20ft double door container has cargo doors at both ends and has made just one loaded voyage since leaving the factory. You get easy access from either end, straight panels, fresh paint and near-new door seals, at a lower price than a factory-new tunnel container. Prime Cargo Box sells this one trip 20ft double door container wind and watertight and CSC plated.
For buyers who want the convenience of two door sets without paying for brand new, it is the grade we recommend most often. Below is what one trip means, the full specification and practical advice for using a tunnel container well.
What Is a One Trip 20ft Double Door Container?
Containers are built in a small number of big factories. To avoid shipping them empty, owners load them with export cargo for their first voyage. Once that cargo is delivered, many are sold locally instead of going back into the shipping system. A container sold after that single journey is called one trip.
Double door, or tunnel, means the container has a full set of cargo doors at each end instead of just one. Open both and you can see, walk or drive a pallet truck straight through. Combine the two and you have a one trip 20ft double door container: near-new condition with access from either end.

Condition You Can Expect
- Straight walls and roof with no repairs
- Original factory paint, maybe with light scuffs from handling
- Clean floor with at most a few forklift marks
- Both door sets opening easily and sealing fully
- The original owner’s logo and container number may still be visible
The owner code and container number are registered with the Bureau International des Containers. They don’t affect use, and we can paint over them if you prefer.
Why a Tunnel Container?
With doors at one end only, whatever goes in first is trapped at the back. In a one trip 20ft double door container, nothing is more than half the length away from a door. That makes it ideal for stock that moves in and out regularly, for keeping two types of goods separate, and for loading at one end and unloading at the other. With both ends open you also get a breeze through the container, which helps on hot days.
One Trip, New or Used?
| Grade | Condition | Price |
|---|---|---|
| New | Unmarked, never used | Highest |
| One trip | One voyage, near new | Middle |
| Used | Years in service, visible wear | Lowest |
On a double door container, condition matters at both ends: two sets of hinges, cams and gaskets. A one trip unit has both in near-new shape. If you want unmarked paint, see the new 20ft double door container. For the lowest price, the used 20ft double door container is the budget option.
Is Two Sets of Doors Worth It?
It depends on your site. If both ends of the container can be reached, a one trip 20ft double door container is almost always worth the small extra cost over a standard one trip 20ft. Every time you need something from the back, you simply walk round to the other door. Over months of daily use, that saves a lot of shuffling of stock.
If one end will sit tight against a wall or another container, the second door set adds little, and a standard one trip 20ft shipping container gives a few centimetres more length for less money. Think about the final position before you choose.
Popular Uses
Customers buy a one trip 20ft double door container for jobs like these:
- Retail and warehouse stock rotation, in one end and out the other
- Builders’ stores with tools at one end and materials at the other
- Farm storage reachable from a yard and a field
- Walk-through workshops, studios and pop-up shops
- Shipping cargo that has to be unloaded in a set order
Our container modification team can add shelving, lighting, vents and personnel doors before delivery.
Layout Ideas
The simplest layout is shelving down both walls with a clear aisle from door to door. If one end is for deliveries and the other for picking, keep heavy and bulky items near the delivery end. In a workshop, put the bench and power at one end and materials at the other, so offcuts and stock never block the way through.
Moving and Placing It
A 20ft container is the easiest size to deliver. It fits most container trucks, needs less room to turn than a 40ft, and many 20ft units have forklift pockets in the base so the empty container can be moved around a yard. When choosing a spot for a one trip 20ft double door container, think about traffic at both ends: a path, a loading bay or a vehicle approach on one side and a work area on the other often makes the best use of the layout.
Site and Delivery
You need space in front of both ends for the doors to open fully, roughly 2.5 m at each end, plus a firm, level base of about 6.5 m by 2.5 m. Concrete, compacted gravel or blocks under the corners all work. Two door frames are more sensitive to an uneven base than one, so check the level before loading. Our shipping and delivery policy covers how delivery is quoted.
What to Ask Before Buying
One trip is a trade description that isn’t always used strictly. Before buying a one trip 20ft double door container from anyone, ask for the manufacture date on the CSC plate, photos of both ends of the actual unit, and confirmation there are no repairs. We include all of this with every quote.
Using It for Export
It carries a valid CSC plate, so a one trip 20ft double door container can be loaded and shipped straight away. Loading from one end and unloading from the other is handy when cargo must come off in a particular order. The external dimensions follow ISO 668, so it fits standard trailers and port equipment.
Care and Security
Grease the hinges and cams at both ends once or twice a year, including the end you use less. Keep the roof clear of water and the bottom rails clear of soil. Each end has padlock lugs, and we can fit a welded lockbox at each end. If one end will rarely be used, face it toward a wall or fence to make it harder to tamper with.

Frequently Asked Questions
Is a one trip 20ft double door container the same as new?
Structurally yes. It has made one voyage, so it may show light handling marks and the original owner’s markings.
Does a one trip 20ft double door container hold less than a standard 20ft?
Very slightly. The second door frame takes about 6 cm off the internal length, which is roughly 0.4 m³ of volume. Most owners never notice the difference, but they do notice not having to dig to the back of the container.
Can I ship goods in a one trip 20ft double door container?
Yes. It carries a CSC plate and is accepted for shipping, and because it is so young the plate is normally well within its examination period.
Are both ends watertight?
Yes. Each door set has full gaskets. Keep the container level so both frames stay square.
Do you deliver worldwide?
Yes. Contact Prime Cargo Box for a delivered price on a one trip 20ft double door container.
