Quick Answer: Per IICL Survey Guidelines, Canadian shipping containers come in four grades, from most expensive to cheapest: One-Trip (essentially new), Cargo Worthy (re-inspected for shipping), Wind and Watertight (used and weather-tight), and As-Is (older, lower grade, at the bottom of the range). The right grade depends on use, not budget alone. Honest delivered pricing, confirmed before payment: get a real quote from Paul or Christian.

“New” and “used” are not enough to describe the shipping container market. The honest market in Canada runs four distinct grades, each with a different price point, a different age and condition profile, and a different fit for different uses. Every supplier worth dealing with stocks at least three of the four and will explain them all on the phone without pressure. Suppliers who pretend there are only “new” and “used” options, or who blur the line between cargo worthy and wind and watertight, are usually trying to push a higher-priced unit on a buyer who would do better with a lower grade.
This article walks through all four grades in order, with the real Ontario 2026 pricing, the structural meaning of each grade, and the use cases that fit each one. By the end, you should be able to call any Canadian container yard and order with confidence using the right vocabulary.
What Are the Four Shipping Container Grades?
Here is the honest market map. Note: every grade requires honest disclosure of cosmetic condition, and every reputable supplier will let you walk and inspect the actual unit before delivery.
| Grade | What it is | Relative price (vs one-trip) | Expected service life |
|---|---|---|---|
| One-Trip (New) | Container made a single journey from manufacturer, essentially new condition | Highest tier (the benchmark, 100 percent) | 30 years or more |
| Cargo Worthy (CW) | Used container re-inspected to international shipping standard, structurally certified | Roughly 60 to 70 percent of one-trip | 25 years or more |
| Wind and Watertight (WWT) | Used container, weather-resistant, doors close and seal, NOT re-certified for shipping | Roughly 40 to 60 percent of one-trip | 20 to 25 years |
| As-Is | Older container with structural questions (floor damage, frame issues, door problems) | Lowest tier (clearance, below WWT) | Varies with condition, repairs likely |
How the Grades Are Decided
Container grading in Canada is informally based on the inspection criteria published by the Institute of International Container Lessors (IICL) and the global standards in the International Convention for Safe Containers (CSC). When a container leaves the global shipping fleet (typically after 10 to 15 years of ocean service), it is inspected and assigned a grade based on its structural condition, weathering, and door/floor integrity. That grade determines what it can be sold for and what uses it is suitable for.
Grade 1: One-Trip (Essentially New)
The premium tier. A one-trip container is built at a factory in China, Vietnam, or another Asian manufacturer, then loaded with cargo for a single ocean crossing to North America. The cargo offsets the shipping cost (otherwise the container would have to deadhead empty across the Pacific, which would push the new-container price much higher). When the container arrives at a North American port and the cargo is unloaded, it has made exactly one journey. The factory paint is still on it, the doors operate cleanly, the floor is unmarked, and there is no rust.
When One-Trip Wins
- Container office, retail pop-up, or commercial conversion where appearance matters
- Residential backyard studio, cabin, or container home build
- Anything visible from the curb, a road, or a customer-facing setting
- Long-horizon investment where you want a 30-year service life
- Buyers who simply prefer to own new, like any other asset purchase
The 50 to 75 percent price premium over a used cargo worthy unit reflects three things: the factory-new paint and condition, the structural certainty (zero wear-and-tear history), and the extended expected service life (30+ years vs 20 to 25 for used). One-trip is the right grade for any use where the container is part of a customer-facing experience or where you want the asset to outlast the buying decision.
Christian LeBlanc, second-generation operator: “Most of our container office and pop-up retail orders are one-trip. Customers see them every day, and a fresh paint job is part of the product. For backyard storage where nobody sees it but you, the math usually favours used. We tell people which is which when they call.”
Grade 2: Cargo Worthy (CW)
The most common used grade. A cargo worthy container has been used in international shipping for several years, then re-inspected against the global Container Safety Convention standard, repaired as needed, and certified to be re-loaded onto an ocean vessel. The structural frame and floor have been confirmed sound for heavy international cargo. The CSC plate is current and valid for re-shipment.
Cosmetically, CW containers carry the marks of their ocean service: surface rust spots on the steel panels, occasional small dents from cargo handling, paint variance from touch-ups and exposure to salt air, and gasket wear at the door seals (often replaced as part of the re-certification). The structural integrity is excellent. The appearance is honestly described as “industrial used.”
When Cargo Worthy Wins
- Export shipping (CSC plate matters)
- High-density industrial storage where weight is a factor
- Container yard or contractor compound use
- Long-term storage where structural certainty matters but cosmetic perfection does not
- Backup or buffer storage in a working operation
Pricing puts CW at roughly 60 to 70 percent of one-trip pricing for the same size. The structural performance is essentially equivalent for non-shipping uses (storage, modification, conversion). The visible difference is cosmetic.
Grade 3: Wind and Watertight (WWT)
The most common grade we deliver to Ontario farms, contractor yards, and residential storage buyers. A wind and watertight container has been retired from international shipping service, inspected for the simpler standard of weather and pest resistance, and certified to be wind-tight (the doors close and seal against wind) and watertight (no leaks under rain or snow load). The CSC plate may have expired and the container is no longer eligible for re-loading onto an ocean vessel.
Visible cosmetic wear is greater than on a CW unit. Surface rust on panels is more extensive. Small dents are more common. Paint variance is significant. Doors close and seal but may require more effort than on a new unit. The interior floor is intact and pest-resistant. The unit is fully usable for any stationary land-based purpose.
When WWT Wins
- Farm storage (equipment, feed, hay, supplies)
- Backyard residential storage (the shed alternative)
- Tool storage on a permanent contractor yard
- Hunting camp or remote cabin storage
- Outdoor shelter for stationary equipment
- Any use where you do not need CSC certification or showroom appearance
WWT is the value sweet spot in the Canadian market. Pricing is roughly 40 to 60 percent of one-trip pricing for the same size. The functional difference for non-shipping use is minimal. The visible difference is real but does not affect storage, security, or weather performance.
The CW vs WWT Decision
The price gap between cargo worthy and wind and watertight on the same 20 foot container is meaningful but modest, since CW typically lands at roughly 60 to 70 percent of one-trip pricing and WWT at roughly 40 to 60 percent. If you are exporting (need a current CSC plate) or running an operation where the container will be inspected by an authority, pay the CW premium. If you are storing on private land in Ontario indefinitely with no plan to ship the unit anywhere else, WWT is the right call and the savings are real.
Grade 4: As-Is
The honest lowest tier. An as-is container is an older unit with one or more structural concerns: floor damage from heavy cargo or rust-through, frame deformation, door problems, hole patches that may or may not be sound, paint failure exposing bare steel. The price reflects these issues. The container is not suitable for storage of valuable items without first being repaired.
We stock as-is units, and we rarely recommend them to buyers unless the buyer specifically knows what they need them for. The honest application for as-is is one of these three uses.
When As-Is Wins
- Cladding stock for an exterior siding project where the container itself will not be the structure
- Scrap-metal value for buyers who plan to disassemble the unit
- Modification donor unit where the buyer plans heavy custom work (cutting in windows and doors, full re-fabrication) and just needs steel to start with
- Container-stacking structural reuse in cases where engineering review confirms the unit can carry the loads
As-is is NOT the right grade for outdoor storage of anything you would mind losing. Floors may leak. Doors may not seal. Roof may have patches. A buyer who orders as-is to save over WWT and then discovers the floor has rusted through has not saved money, they have transferred the cost to repair work.
Why We Disclose As-Is Even Though We Rarely Recommend It
The honest reason every reputable supplier carries as-is in inventory is that the market needs a clearance tier for older units. Pretending it does not exist would push buyers into Wind and Watertight units that should themselves be downgraded, or worse, push old units into the CW category where buyers would be misled about the structural certainty. Listing as-is openly is the honesty signal. We will tell you if the box you are looking at is properly graded as-is and what its real use case is. That conversation is part of the brand, not a sales loss.
The CSC Plate and What It Means
The CSC plate, short for Container Safety Convention plate, is a metal data plate riveted to the inside of every ISO-certified container. It carries the container’s manufacture date, owner, identification code, and the date of its last inspection. The CSC plate is required for any container being loaded onto an ocean-going vessel for international shipping. The certification is valid for 5 years initially, then on periodic inspection.
| Grade | CSC plate status | Re-shippable internationally? |
|---|---|---|
| One-Trip | Current, recent factory inspection | Yes |
| Cargo Worthy (CW) | Re-inspected, current and valid | Yes |
| Wind and Watertight (WWT) | Expired or not maintained | No |
| As-Is | Expired, structural issues may prevent re-certification | No |
For Canadian buyers using the container statically on land (storage, conversion, modification), the CSC plate status does not affect use. The container will not be loaded onto a ship again. For buyers using the container as part of an active international shipping operation (export businesses, freight forwarders), the CSC plate is a hard requirement and you must buy a CW or one-trip unit with current certification. The cost of getting an expired CSC plate re-certified is meaningful, sometimes more than the price gap between WWT and CW on the original purchase, which is why the right way to think about CSC status is “decide once at the time of purchase” rather than “upgrade later.”
Which Grade Fits Your Use
Here is the practical decision grid we walk through with buyers on the phone.
| Your use | Best grade | Why |
|---|---|---|
| Container office or pop-up retail | One-Trip | Customer-facing appearance, long service life |
| Backyard cabin, studio, or container home | One-Trip | Aesthetic and structural certainty for a long-build investment |
| Active export shipping | Cargo Worthy | Valid CSC plate, structurally inspected, lower cost than one-trip |
| Industrial yard storage, contractor compound | Cargo Worthy or WWT | Either works; CW if you anticipate moving the container, WWT if it is stationary |
| Farm equipment and feed storage | Wind and Watertight | Stationary on land, weather-tight, value sweet spot |
| Residential backyard storage | Wind and Watertight | Shed alternative at a similar or lower price point |
| Hunting camp or remote cabin storage | Wind and Watertight | Pest-resistant, weather-tight, no shipping requirement |
| Heavy custom modification (cutting windows, full rebuild) | As-Is | Lowest steel cost for buyers who plan extensive work |
| Cladding or scrap-metal use | As-Is | Steel by the foot, not the box |
| Container will be visible to neighbours or customers | One-Trip or fresh-painted CW | Appearance matters when others see it |
How Ontario Orders Actually Distribute
Across our Brantford yard’s 30 years of deliveries, the order mix runs roughly: 25 percent one-trip (offices, conversions, residential), 30 percent cargo worthy (industrial, export, contractor), 40 percent wind and watertight (farms, residential storage, general use), 5 percent as-is (modification donors, cladding, scrap). The WWT dominance reflects what most Ontario buyers actually need: weather-tight stationary storage. The one-trip premium is real but only worth paying when the use case calls for it.
Why Visiting the Yard Matters at Every Grade
Grading is informally standardised but never perfectly. A cargo worthy unit at one yard might be marginally better or worse than a CW unit at another yard, depending on how the supplier sources and inspects. A wind and watertight unit at one yard might be near-CW quality and another might be near-as-is. The only way to know what you are actually buying is to look at the specific container with your own eyes.
Van Blanc has been doing this for 30 years from our Brantford yard at 90 Morton Avenue East. Customers from Toronto, Hamilton, Cambridge, Kitchener-Waterloo, Brockville, and points further drive to walk the rows before they commit. We let them inspect, run their hand along the corner castings, check the door seals, look at the floor, ask hard questions about the CSC plate. That transparency is the only way the grading vocabulary becomes useful instead of marketing.
Christian LeBlanc: “A buyer who walks the yard sees the difference between a near-CW WWT unit and a near-as-is WWT unit in about 10 seconds. The photos do not capture it. The phone description does not capture it. Standing in the gravel beside two units of the same grade, the difference is obvious. That is why we encourage every buyer to visit before they pay.”
Frequently Asked Questions
What is the difference between a one-trip and a new shipping container?
In current Canadian usage, they mean the same thing. A “new” container is one that has made one journey from the manufacturer to a North American port, hence the more accurate term “one-trip.” There is essentially no such thing as a factory-fresh, never-shipped container in the Canadian retail market, because deadhead shipping would push the price into uneconomic territory.
How can I tell if a container is Cargo Worthy versus Wind and Watertight?
The CSC plate is the cleanest test. A CW container has a current, valid CSC plate inside the door, with an inspection date within the last 5 years. A WWT container has an expired CSC plate or none maintained. Visible cosmetic differences also help: CW units typically have lighter surface rust and tighter door seals than WWT.
Is a Wind and Watertight container safe for outdoor storage in an Ontario winter?
Yes. The “wind and watertight” certification specifically confirms that the container is weather-resistant under normal precipitation and wind load. WWT units handle Ontario winters, including snow load, freeze-thaw cycles, and rain, without issue. The interior remains dry. The pest-resistant marine plywood floor handles the seasonal temperature swings.
Why is there so much price variation within a grade?
Three reasons. First, regional freight cost varies by delivery zone (Northern Ontario premium freight vs Southern Ontario standard). Second, container age within a grade varies (a 10-year-old CW differs from a 7-year-old CW). Third, supply-and-demand cycles in the global container market shift prices over months. Reputable suppliers quote honestly within their specific regional cost structure.
Are as-is containers worth buying?
For specific uses: cladding stock, scrap metal, or extensive custom modification where the buyer plans to fabricate the container into something new. For straightforward storage, no. The savings over a WWT unit usually evaporates in repair work to make the as-is container weather-tight, secure, and floor-sound. We sell as-is when the buyer specifically asks for it and explains their use.
How long do used shipping containers last in Ontario?
A Wind and Watertight container in stationary land use lasts 20 to 25 years with minimal maintenance. A Cargo Worthy container in similar use lasts 25 years or more. A One-Trip container can serve 30 years or more. Maintenance is essentially: keep the unit on a level pad, allow drainage so water does not pool against the floor, and address any surface rust spots before they progress. That is the entire maintenance schedule.
Can a Wind and Watertight container be upgraded to Cargo Worthy?
Sometimes, yes, if the underlying structural condition is sufficient. The upgrade requires a formal IICL or equivalent inspection, repair of any deficiencies, and re-certification with a new CSC plate. The cost of upgrading depends on what repairs are needed, and it can run high enough to outweigh the original gap between the two grades. For most Ontario stationary-storage buyers, this is unnecessary. For buyers planning to re-ship the container internationally, sometimes it makes sense.
