Container Condition Grades: A Virginia Buyer's Guide

Why Condition Grade Matters

The condition grade determines how long a container lasts. It also determines whether you can convert the unit, whether valuable equipment can be stored inside, and whether the visible cosmetics matter for your application.

Economy

Container One's most affordable grade remains functional for storage and shows visible wear. Expect:

• Surface rust on most external panels.
• Paint chipping, faded original branding, evidence of multiple repaints.
• Dents and dings on side walls and roof. None should be deep enough to compromise structural integrity.
• Floor wear: original plywood with industrial residue, possible burn marks, possible patches.
• Door hardware functional but stiff.

Best for: Rough storage on a working farm or jobsite, where appearance is not a factor. Not recommended for storage of valuable, rust-sensitive, or moisture-sensitive contents without ventilation upgrades.

What it looks like: Visible rust streaks, chipped paint, repaired patches.

Wind and Water Tight (WWT)

WWT means the container is structurally sound and guaranteed not to leak. Specifically: Container One provides the warranty. Written warranty terms.

• Door seals checked and confirmed weatherproof.
• Roof inspected for holes, dents, and rust through-spots.
• Floor inspected and confirmed structurally sound. May show wear but no rot, no holes, no soft spots.
• Walls inspected and confirmed solid. Surface rust and cosmetic dings are acceptable.
• Door hardware functional.

WWT is not the same as cargo worthy. WWT means the container keeps wind and rain out. Cargo worthy means the container can pass a marine survey to be re-certified for shipping by sea or rail.

Best for: General storage, contractor jobsite tools, farm equipment, household goods during a renovation, on-site materials during construction.

What it looks like: External panels show some surface rust and cosmetic wear, but doors close cleanly, seals look intact, and the interior is dry. The unit looks used but functional.

Cargo Worthy (CW)

The Cargo Worthy grade is based on the container's structural condition. That means:

• All structural members (corner castings, side and end frames, undercarriage) inspected and confirmed sound.
• Walls, roof, and floor confirmed weatherproof and load-rated.
• Door hardware tested.

For storage, CW works much like WWT; the difference is that a CW unit can pass a marine survey. Pricing sits between WWT and one-trip.

Best for: Buyers who plan to ship the container by sea or rail after a marine survey, and buyers who want better cosmetics than WWT without paying for one-trip.

What it looks like: Cleaner overall appearance than WWT, with visible age but a more uniform exterior.

One-Trip (Sometimes Sold as Like-New)

A one-trip container has made a single ocean voyage, typically loaded from a manufacturing facility in Asia to a North American port. After unloading, the unit goes into the resale market essentially brand new. Specifically:

• Original factory paint, with minor scuffs from the single shipping journey.
• Floor in excellent condition, no industrial wear.
• Doors and seals tight.
• Interior clean and dry, no residue.
• Minor cosmetic marks consistent with one ocean trip and one truck transfer.

Best for: Conversion projects (offices, workshops, tap rooms, tiny homes), food-adjacent or sensitive storage, customer-facing placement, and anyone who wants the cleanest grade.

What it looks like: Factory paint, sharp graphics, clean interior. Looks like a new container with light handling marks.

Warranty by Grade

Container One's warranty depends on the grade: Container One provides the warranty. Written warranty terms.

Working refrigerated containers carry a 1-year leak-free guarantee. Ask a Container One sales representative about coverage for the refrigeration unit itself before buying. Container One provides the warranty. Written warranty terms.

How to Choose for Your Use Case

The match between use case and grade:

Inspecting on Delivery

Whatever grade you select, the visual checklist is the same:

1. Floor. Walk it. Listen for soft spots. Look for water staining or rot. A damaged floor is costly to repair after delivery.
2. Door seals. Look for daylight around the closed doors from inside while a second person stays outside with the doors unlatched. Daylight means a gap in the seal.
3. Roof. If you can climb up safely, check for dents that pool water, rust through-spots, and obvious patches.
4. Corner castings. The eight corner blocks should be intact and free of major damage. They carry the entire load when the unit is lifted or stacked.
5. Side walls. Look for bulges, deep dents, and heavy rust patches. Surface rust is normal; structural rust is not.
