Container Condition Grades in BC: New vs Used
One-trip, cargo-worthy, wind & water tight, or as-is? Here's what each grade actually means — and how to pick the right one for your project in British Columbia.
When you start shopping for a shipping container, the first surprise is that "used" isn't one thing. Two 20ft boxes sitting side by side in our yard can differ by years of life and hundreds of dollars, and the only way to tell them apart is the condition grade. Get the grade right and you pay for exactly the box your project needs; get it wrong and you either overspend on cosmetics you'll never see or end up with leaks over your equipment.
Here's the short answer: for clean, weather-tight on-site storage, a wind & water tight or cargo-worthy used container is the value sweet spot for most BC buyers. Choose one-trip ("new") when looks matter — a customer-facing site, a modification project, or a box you want to last decades with minimal rust. Reserve as-is for cheap material storage where a few dings don't matter. The rest of this guide explains why.
The four grades you'll actually be quoted
Container grading isn't governed by one universal standard, but the trade across Canada uses four consistent terms. Knowing them lets you compare quotes apples-to-apples instead of guessing what "good condition" means to a given seller.
- One-trip / New: Built overseas and used for a single loaded voyage to North America, so it arrives near-new — straight walls, intact paint, tight door seals, and a manufacturer's plate only a year or two old. The cleanest box you can buy short of a custom build.
- Cargo-Worthy (CW): Inspected and certified structurally sound enough to still ship cargo internationally. Expect surface rust and cosmetic dents, but no holes, no soft floor, and doors that seal. The go-to grade when you want a proven, certifiable box at a used price.
- Wind & Water Tight (WWT): Guaranteed to keep weather out — no daylight through the walls, no leaks at the roof or seams — but not certified for ocean shipping. More cosmetic wear than CW, and the best price for dry, secure storage that stays put.
- As-Is: Sold without a weather-tight guarantee. It may have a pinhole leak, a patched repair, or a sticky door. Cheapest of all, fine for non-sensitive storage — but inspect it in person and know what you're accepting.
Grades at a glance
| Grade | Weather-tight? | Ship cargo? | Cosmetics | Relative price |
|---|---|---|---|---|
| One-trip / New | Yes | Yes | Near-new | Highest |
| Cargo-Worthy | Yes | Yes (certified) | Light wear | Mid |
| Wind & Water Tight | Yes | No | Visible wear | Lower |
| As-Is | Not guaranteed | No | Variable | Lowest |
Why grade matters more in BC
British Columbia is hard on steel. Coastal damp and Interior winters mean condensation, freeze-thaw cycles, and persistent moisture work on every weak seal and scratch in the paint. A box graded wind & water tight or better will shrug that off for years; an as-is unit with an existing pinhole can let a slow drip ruin whatever sits beneath it through a wet Lower Mainland winter.
The flip side: you don't need a pristine one-trip box just to keep gravel-pad storage dry behind a shop in Prince George or Kamloops. Surface rust on a cargo-worthy container is cosmetic, not structural, and a touch-up of paint goes a long way. Match the grade to the job and the climate, not to the showroom.
How to choose by use case
The clearest way to land on a grade is to start from what the container is for:
- Customer-facing or branded: Choose one-trip. A clean, dent-free box paints well and photographs well — the right base for a retail pop-up or a wrapped, branded container.
- A modification project: Lean one-trip or strong cargo-worthy. When you're cutting in doors, windows, or insulation, you want straight walls and minimal rust to build on — see our container modifications options.
- Dry on-site storage: Wind & water tight is the value pick — guaranteed dry, at the lowest weather-tight price.
- You may resell or ship later: Cargo-worthy keeps the certification door open for international transport.
- Cheap, non-sensitive storage: As-is can work — just inspect it first.
The one rule that saves money
Buy the lowest grade that still keeps your contents dry. For most storage that's wind & water tight; pay up to one-trip only when looks or modifications truly demand it. You're buying weather-tightness, not paint.
What to check before you buy
Whatever grade you settle on, a five-minute inspection protects you. Stand inside with the doors shut and look for pinholes of daylight, especially along the roof and the door seals. Check the floor for soft spots, scan the bottom rails and corners for heavy rust, and make sure both doors swing and lock cleanly. A reputable BC dealer will let you inspect the exact unit — and grade it honestly — before delivery.
