Buying guide
Container condition grades explained
Grade drives price more than any other factor. Here is what each of the four grades we sell actually means on the ground, and which one suits your use.
One-Trip (new)
Built for a single loaded voyage from the factory, then sold. Paint is factory-applied and consistent, floors are clean, doors seal on original gaskets and the unit is shipping-certified. Expect minor transit scuffs and possibly one or two small dents — that is normal and does not affect performance.
- Best for: retail and office conversions, client-facing sites, long-term assets.
- Watertight: yes.
- Shippable internationally: yes, with a valid CSC plate.
- Holds resale value best of all grades.
Cargo Worthy (CW)
A used unit that passes a structural survey against ISO criteria and may still carry international cargo. Surface rust, patch repairs and mismatched paint are expected; structural members, floors and door gear are sound.
- Best for: buyers who need certification but not new appearance, including export packing.
- Watertight: yes.
- Shippable internationally: yes, subject to a current survey and CSC plate.
- Typically 25–40% below a One-Trip unit of the same size.
Wind & Water Tight (WWT)
Sound for storage — no light through the walls or roof, doors close and lock — but not surveyed for sea carriage. This is the workhorse grade for site stores, farm storage and workshop conversions.
- Best for: on-site storage, workshops, secure stores, conversions where you will paint anyway.
- Watertight: yes.
- Shippable internationally: no.
- Cosmetic condition varies more widely than CW; ask for photographs of the actual unit.
As-Is
Sold with known defects, listed individually on the quotation and invoice — a soft floor section, a corroded panel, a door that needs gear work, or roof ponding. Priced for buyers who will repair, cut up or use the shell as material.
- Best for: fabrication feedstock, static shells, low-value storage where leaks are tolerable.
- Watertight: not guaranteed.
- Shippable internationally: no.
- Inspect before purchase — this is the one grade where photographs are not enough.
How to choose
- Will anyone stand inside it or see it from a customer area? Choose One-Trip.
- Does it need to travel by sea or satisfy a shipping line? Choose Cargo Worthy with a current CSC plate.
- Is it a dry store on your own site? Wind & Water Tight is usually the best value.
- Are you cutting it up or repairing it yourself? As-Is is the cheapest steel per square metre.
What to check on any used unit
- Stand inside with the doors shut and look for daylight at the seams and roof.
- Probe the plywood floor at the door threshold and the centre — soft spots are costly to replace.
- Open and close both doors fully; check hinges, cams and gaskets.
- Check the roof for ponding and previous patch welds.
- Confirm the serial (BIC code) matches the plate and the paperwork.
