Ocean containers are standardized, but not identical. The size and type decide which chassis we use, how much the empty container weighs, and sometimes whether special handling is needed.
Common sizes
| Size | What it is | Notes |
|---|---|---|
| 20’ | Short standard container | Often used for heavy, dense cargo. Heavy 20s can be hard to balance on axles; see weight and overweight. |
| 40’ | Standard long container | The most common size. |
| 40’ high cube (40HC) | 40’ container about a foot taller | Same chassis as a 40’, more cubic space. |
| 45’ | Long high cube | Needs a chassis that fits 45’. |
Common types
- Dry (standard). Most general cargo.
- Refrigerated (reefer). Has a refrigeration unit. It may need a generator set (genset) for the road and temperature instructions. We review these.
- Open top and flat rack. For oversized or top-loaded cargo. They often involve over-dimension or securement questions and are reviewed individually.
- Tank. For liquids, often regulated. Reviewed individually.
Where to find it
The container size and type are on the arrival notice (imports), the booking confirmation (exports), or the bill of lading, often as an ISO code such as 22G1 (20’ dry) or 45G1 (40’ high cube dry). If you’re not sure, choose “Not sure” in the quote form and we’ll confirm it.
