Shipping container grades explained: new, cargo-worthy and as-is

Start with the contents, then choose the grade

For furniture, boxed stock or equipment that needs protection from rain, compare cargo-worthy or new single-trip options. For a project where you intend to repair or alter the steel, an as-is unit may be worth assessing against its specific faults. As-is is not sold watertight.

Think about how often you will open the doors, whether appearance matters at the proposed position, and whether the contents are sensitive to moisture. Those details make a more useful enquiry than asking for the best-looking grade name.

Compare the three container grades

These labels describe condition, not control of condensation. For the decision between new and used, read our new vs used guide.

Container condition terms explained

• Single-trip, one-trip and new-build: names commonly used for a newly manufactured container that has carried one loaded journey. Handling marks are still possible.
• WWT (wind and watertight): a light test checks for daylight entering through holes or gaps with the doors closed. It helps identify openings; it does not establish shipping certification. Budget's wind and watertight claims apply to cargo-worthy or better, not as-is.
• IICL: an inspection standard from the Institute of International Container Lessors, with stricter condition criteria than cargo-worthy. A label alone does not establish current certification or mean Budget has a unit of that grade available.

New single-trip: fewer signs of previous use

A single-trip container has carried one loaded journey from manufacture. It can suit a visible business location or a storage fit-out where a tidier starting condition matters. It may still have scuffs or handling marks; single-trip does not promise a flawless finish.

Ask for the actual unit's condition and dimensions rather than treating a catalogue image as the container you will receive. If your layout depends on a particular door opening or floor arrangement, confirm it before ordering shelving or equipment.

Cargo-worthy used: separate appearance from function

Budget's cargo-worthy units are checked wind and watertight before release. Used containers can show dents, surface rust, repairs and previous markings. A worn finish alone does not tell you whether a unit will suit your storage.

Ask about the floor, door operation, seals and repairs on the container being quoted. Photos help you judge cosmetic wear; ask the team to explain anything you cannot assess from an image. If you need the unit for freight rather than stationary storage, discuss the required inspection and documentation for that job separately.

As-is: the disclosed faults decide the job

An as-is container is sold with disclosed faults and is not sold watertight. The useful question is which defects this particular unit has: a damaged floor, corroded panel or door that needs work will affect different projects in different ways.

Do not assume an unspecified repair will make it suitable for dry storage. Ask what work is needed, whether that work is included, and what condition the unit is being sold in. For a conversion, check the proposed alterations with the appropriate trades before choosing a shell.

If the contents would be damaged by incoming rain, compare a cargo-worthy or new unit instead of treating as-is as an equivalent storage option.

What wind and watertight does not answer

For cargo-worthy or better, wind and watertight describes protection from wind and rain through the container envelope. It does not mean flood-proof, fire-proof, insulated or temperature-controlled. It also does not prevent condensation forming inside.

Wet tools, damp furniture or moisture trapped in packing can create problems even when rain is kept out. Tell the team about moisture-sensitive contents and ask whether ventilation or a different storage arrangement is appropriate. A condition grade is not approval for food, chemical or habitable use.

Read past A grade, B grade and premium used

Different sellers may use condition labels differently. Ask what their label means for the actual unit: its structure, floor, doors, seals and disclosed faults. Compare those answers with your intended use rather than assuming matching letters describe matching containers.

A shipping-related inspection label also needs context. If a listing mentions certification or an inspection standard, ask which documentation is supplied and whether it meets the requirements of your intended transport. Do not infer current shipping approval from an old plate or an advert.

Five questions to include in your enquiry

1. What is going inside? Describe your contents and whether they must stay dry, so the team can discuss a suitable condition.
2. Which unit does the quote cover? Confirm the size, grade and any faults, rather than relying on a representative image.
3. Can I see it? Photos of the actual container are available on request before delivery. Ask to see the floor, doors and any repairs or defects you want explained.
4. Will it fit the job and the site? Check the dimensions and door opening, then describe the gate, approach and placement area using the delivery checklist.
5. What does the complete quote include? Confirm container condition, freight inclusions, unloading and GST treatment in writing. Use the container quote guide to compare the same scope.

You can enquire before deciding on a grade. Send the delivery suburb and describe the job; leave the condition as Help me choose rather than guessing.
