BUYER'S GUIDE

How to choose the right shipping container.

Everything to check before you buy — size, condition grading, common uses, and what your delivery site needs to be ready for drop-off.

Choosing the right size

Container sizes are described by length; height and width follow standard ISO dimensions unless you're looking at a High Cube unit.

Understanding condition grades

Every listing states a condition grade so you know what to expect before it arrives.

NEW / ONE-TRIP

New

Shipped once from the factory. Minimal cosmetic wear, no structural repairs.

GRADE A

Cargo Worthy

Certified watertight and structurally sound. Visible wear consistent with active service.

GRADE B–C

Wind & Water Tight (WWT)

Sealed against the elements but with more cosmetic wear — dents, surface rust, or patched repairs.

Common uses

Storage

On-site secure storage for equipment, inventory, or seasonal items.

Shipping

Standard freight and export use, ISO-certified for ocean and rail transport.

Conversion

Foundation for site offices, workshops, or container-home builds.

Site office

Insulated and modified units used as job-site or event offices.

Before you buy: site checklist

Flat, stable ground

The delivery surface should be level and able to bear the container's weight without shifting.

Truck & tilt-bed clearance

Confirm access for a tractor-trailer, plus rear clearance if delivering by tilt-bed — see our Shipping Policy for specifics.

Permits & zoning

Some municipalities and HOAs require a permit for container placement, especially for long-term or converted use.

Ventilation, if converting

Conversions for offices or living space typically need added ventilation and insulation — plan this before delivery.

Common questions

Do I need a permit to place a container on my property?

It depends on your city or county and how long the container will stay. Check with your local zoning office before ordering, especially for permanent placement or conversions.

How much clearance does tilt-bed delivery need?

Typically [XX ft] of straight, clear space behind the drop point, plus overhead clearance — see our Shipping Policy for details.

What's the difference between Cargo Worthy and Wind & Water Tight?

Cargo Worthy units are certified for active freight use and have less cosmetic wear. WWT units are sealed and usable but show more visible wear — a good fit for storage rather than shipping.

Can I see photos of the exact unit I'm buying?

Listings show photos representative of the stated grade. If you'd like photos of the specific unit reserved for your order, contact us before checkout.
