Container Type Guide
Which shipping container type is right for you?
There is more to choosing a container than 20ft versus 40ft. The type (standard, high cube, refrigerated, open-top and more) decides what you can store, how you load it, and what you pay. Answer four quick questions below and we will point you at the right one, then connect you with verified suppliers near you.
The short version
Most buyers need a standard "dry" container in a 20ft or 40ft size. It is the cheapest, the easiest to find, and it handles storage, shipping and most conversions.
You only need a specialty type for a specific reason: cold or frozen goods point to a refrigerated unit, tall interiors to a high cube, top-loaded or oversized cargo to an open-top or flat rack, and easy loading to a double-door. Below, we match each one to what you are actually trying to do.

Short guide, part one
Container types in sixty seconds
Every container type is the same steel box with one thing changed. Learn the five things that change and you can read any supplier listing without guessing.
1. Height
Standard boxes are 8ft 6in tall. Add a foot and it becomes a high cube at 9ft 6in. Length and width never change with type.
Changes: headroom, delivery clearance, price
2. Doors
One end is standard. Doors on both ends make a tunnel or double-door. Doors down a full side make an open-side.
Changes: how you load, usable wall space
3. Roof
A fixed steel roof is standard. Swap it for a tarpaulin and you get an open-top. Remove the roof and sides and you get a flat rack.
Changes: crane loading, weatherproofing
4. Temperature
Bare steel is standard. Insulated walls slow temperature swings. Add a powered cooling unit and it is a reefer.
Changes: power needs, running cost
5. Condition
Not a type, but it moves the price as much as one. The same 20ft box ranges from one-trip to sold as-is.
Changes: price, looks, shipping certification
Type and size are separate decisions. Once you know your type, pick a length on the container size guide, or go straight to 20ft and 40ft.
The main types
Every common container, and who it is for
Each card covers what it is, what it is best for, and the trade-off people miss. Price tier runs from $ (most affordable) to $$$ (premium). Availability is how easily verified suppliers tend to stock it.
Standard (dry) container
The default steel box: corrugated walls, cargo doors at one end, 8 ft 6 in tall. If nothing below describes a special need, this is the one.
- Sizes: 10, 20 and 40 ft
- Best for: storage, freight and most conversions
- Heads-up: doors at one end only, and a 10 ft is often cut down, so it can cost more per foot than a 20 ft
High cube container
Same length and width as a standard, but a full foot taller at 9 ft 6 in. That extra headroom is the whole point.
- Sizes: mostly 40 and 45 ft, with 20 ft high cubes rarer
- Best for: conversions, tall pallets and equipment, room to insulate and add flooring
- Heads-up: needs more vertical clearance for delivery and will not fit under low structures
Refrigerated container (reefer)
Insulated walls plus a powered cooling unit that actively holds a set temperature, anywhere from deep-frozen to chilled.
- Sizes: 20 and 40 ft, and the 40 is usually a high cube
- Best for: food, pharma, florals and cold storage
- Heads-up: needs continuous power, and on used units you should confirm the cooling unit actually runs cold
Open-top container
A removable tarpaulin or hard top instead of a fixed roof, so cargo can be craned in from above.
- Sizes: 20 and 40 ft
- Best for: cargo taller than the doors, machinery and top-loaded bulk
- Heads-up: the top is not as secure or weatherproof as a solid roof, so it is a poor pick for long-term outdoor storage
Flat rack container
Just a strong base with two end walls, no roof and no sides. Built for loads a normal box cannot hold.
- Sizes: 20 and 40 ft base
- Best for: oversized, heavy or wide loads such as vehicles, machinery, pipes and boats
- Heads-up: no weather protection, so treat it as a transport type rather than a storage box
Double-door (tunnel) container
Cargo doors on both ends. Walk or drive straight through, or split the box into two lockable halves.
- Sizes: 10, 20 and 40 ft, often as a modification
- Best for: loading from either end, drive-through access and easy full-length reach
- Heads-up: two door ends means more seals to maintain and a little less solid wall for shelving
Do not see an exact match? Suppliers can also modify standard boxes with side doors, roll-up doors, extra vents, windows or partitions. Describe what you need on the quote form and we will route it to suppliers who build it.
Less common, still useful
A few specialty configurations
You will meet these less often, but they solve very specific problems.
Open-side container
Doors run the full length of one side, so the entire box opens at once instead of just one end.
Best for: workshops, pop-up retail, and loading pallets side by side.
Insulated container
Insulated walls but no powered unit. It buffers temperature swings rather than actively cooling, so it is far cheaper to run than a reefer.
Best for: moderate climate control for dry goods, gear and workshops.
Tank container
A cylindrical tank held inside a standard container frame, for liquids, food-grade fluids, chemicals or gases.
Best for: bulk liquid transport and storage, and heavily regulated.
Short guide, part two
Choose your container type in four steps
If you would rather work it out yourself than use the selector, this is the same logic written out. Answer each step in order and you will land on one type.
-
Start with the job, not the box
Storage, shipping and conversions all point at a plain standard container. Only move off it when a real constraint forces you to.
Ask: would a plain steel box actually fail at this job? -
Check the temperature need
Holding a setpoint means a reefer and a permanent power supply. Only smoothing out heat and cold means an insulated box at a fraction of the running cost.
Ask: do I need a set temperature, or just less swing? -
Measure the load and the headroom
Cargo taller than the door opening needs an open-top. Loads wider than the box need a flat rack. A finished interior you will stand up in wants a high cube.
Ask: what are the tallest and widest things going in? -
Decide how you will load it
Loading from one end is standard. From both ends is a double-door. Along the whole length is an open-side. Ordering it that way beats retrofitting later.
Ask: where will a forklift or pallet actually go in?
Just as important as type
Then choose a condition grade
Two identical 20ft boxes can differ by hundreds of dollars purely on condition. Here is what the grades actually mean.
| Grade | What it means | Price | Best for |
|---|---|---|---|
| New / One-trip | Shipped only once from the factory. Near-pristine paint, clean interior, doors seal well. | $$$ Highest | Conversions, anything customer-facing, long-term ownership. |
| Cargo-worthy (CW) | Certified structurally sound and seaworthy. Used, with some dents and surface marks. | $$ Mid-high | Shipping goods, or storage you want to rely on. |
| Wind and watertight | Keeps wind and water out but shows more cosmetic wear. May not be certified for shipping. | $ Mid | On-site storage where looks do not matter. |
| Used / As-is | Sold as seen, so it may have dents, surface rust or patched repairs. | $ Lowest | Budget storage, but inspect it or ask for photos first. |

Not every type comes in every grade. One-trip dry containers are everywhere, but one-trip reefers and flat racks are much rarer. Availability drives price too, which is why it pays to compare a few verified suppliers. See how we check them on the supplier score page.

Price tiers are relative, not fixed quotes. A used standard box and a one-trip high cube can overlap. For real numbers in your area, run the cost estimator or compare quotes from verified suppliers.
Avoid these
Common mistakes buyers make
Most container regrets come down to the same handful of oversights. Check yourself against these before you commit.
-
Paying for a reefer when insulation would do
A refrigerated unit costs far more to buy and runs up power bills. If you only need to slow temperature swings rather than hold a setpoint, an insulated container is the cheaper, right-sized answer.
-
Forgetting delivery clearance for a high cube
That extra foot of height is easy to love and easy to overlook. A tilt-bed truck needs vertical and overhead room to place a high cube, so measure gates, eaves and low branches first.
-
Buying "as-is" sight unseen
As-is is the cheapest grade for a reason. Without photos or an inspection you can inherit dents, pin-holes or a floor that needs replacing. Always ask for current pictures, or step up to cargo-worthy or wind and watertight.
-
Picking the wrong door configuration
Standard boxes open at one end only. If you need to load from both ends or drive through, that is a double-door or open-side unit, and it is far cheaper to order it that way than to retrofit later.
-
Not checking a used reefer's cooling unit
A used refrigerated container can look perfect and still have a tired compressor. Ask for the unit's service history and a pull-down test to a target temperature before you buy.
