Whether it is a near-free unit from the classifieds or a factory-new food-grade IBC, condition decides price, purity and approval — often by a factor of five to ten. This guide explains, manufacturer-neutrally, what new, rebottled, reconditioned, washed and used actually mean, which condition is enough for which purpose, and how to spot a good used IBC.
The five condition classes
| Condition | What it means | Suitable for | UN / food |
|---|---|---|---|
| New (factory-fresh) | Unused HDPE bottle, new cage, pallet and fittings — no prior load. UN approval possible from the factory (food-grade does not automatically mean UN-approved). | Anything: drinking water, food, dangerous goods (with UN + the right gasket). | Food-grade; UN possible |
| Rebottled (new bottle) | A factory-new inner bottle in the cleaned, inspected old cage and pallet. Product contact is as-new; suitable for sensitive media and, with the right bottle, food. | Like new — sensitive media and food with a food-grade bottle. | Food-grade; UN possible |
| Reconditioned / washed | The original bottle stays in, is machine-cleaned, inspected, gaskets/fittings replaced. Discolouration and residues can remain. | Water, rainwater, garden, non-critical process use. NOT for food or drinking water. | Not declarable as food-grade |
| Used / unrinsed | “As seen”, emptied but not professionally cleaned — cleaning is the buyer’s job. The declared previous product decides what it can be used for. | Only with a harmless food previous content, for water/garden; chemical previous content = avoid. | Not declared; UN status unclear |
| Private / “free” (classifieds) | Single units, cheap to free. No cleaning or condition guarantee, previous contents often only stated verbally, collection only. | Rainwater, décor, trellis, ballast — never for food. | No guarantee; usually no valid UN |
When used pays off — and when it does not
Condition is by far the biggest lever on price: the same 1000-litre IBC can cost several times more new than cleaned-and-used, and more again than a private “as seen” unit. For rainwater, garden irrigation, process water or as ballast, the cheaper cleaned used IBC is the right choice — you need no UN approval, and an expired approval is not a fault, just a lower price. Only the previous content has to be harmless. For drinking water, food or dangerous goods on the road, saving on condition is the wrong economy — there, new or rebottled is the only sound route.
What “reconditioned” really means — ask
The key point: sellers use “reconditioned” inconsistently. Sometimes there is a new inner bottle (effectively “rebottled”), sometimes the cleaned original bottle stays in the inspected cage. The difference decides purity and whether it can carry dangerous goods — so always ask directly: new bottle, or cleaned original bottle? Professional processing runs to certified, audited procedures (emptying, internal cleaning, visual inspection, leak test, fitting replacement). But an IBC is fit for dangerous goods not because of the marketing word — only through the data plate, a valid UN marking, a passed inspection, medium compatibility and a deadline still in date. The grades in full are on our used & reconditioned IBC page.
Which condition for which purpose?
| Use | Minimum condition | What is mandatory |
|---|---|---|
| Drinking water | New | Product-contact parts documented as food-safe, a food-safe gasket that suits the medium. Used or reconditioned is off-limits — the previous content is never known for certain. |
| Food / beverages | New (food-grade) or rebottled | A new or rebottled bottle, documented under the food-contact regulations. A used “food” IBC is only good for the same non-critical previous content. |
| Rainwater / garden | Used / reconditioned | No approval needed — this is where the cheap IBC is the right call. A black/opaque version fights algae. For edible crops, check the previous content is harmless. |
| Fuel / oil storage | A container released for it | Transport: a valid UN marking matching the medium. Storage: a container the manufacturer releases for fuel, a Viton/FKM gasket (EPDM swells), secondary containment, a load-bearing level base and earthing. A plain water IBC is not enough. |
| Dangerous goods (road) | New or professionally reconditioned | A valid UN marking that matches the medium, packing group, density and gasket (not a blanket permit). Mind the periodic inspection and build-age limits for the plastic inner bottle. |
| Aggressive chemicals | New or re-approved | Material compatibility of BOTH the inner bottle AND the gasket with the medium. For a low flash point, an earthed/Ex-rated IBC plus containment. |

Request quotes freeFood-grade, UN-approved, fuel-suitable — three different things
These three get confused constantly but mean entirely different things. Food-grade means the product-contact parts are intended and documented for food contact under the food-contact regulations — reliable only with a new or rebottled bottle plus proof, or a demonstrably clean food-only previous use; a formerly chemical container does not become a food container by washing (food-grade IBCs explained). UN approval is a type-tested, time-limited dangerous-goods property for transport, and the marking must match the actual medium (the UN code mark by mark). Fuel-suitable is a question of the gasket: Viton (FKM), because EPDM swells. Food-grade is not the same as UN-approved, and neither is the same as fuel-suitable.
Buying used: the inspection checklist
- Always ask the previous contents: read the original label, any dangerous-goods sticker and the UN number. No label and no proof = walk away.
- “Food-grade” is a property of the bottle, not proof of the previous content — for water/food, demand a genuine food-safe previous use or a new/rebottled bottle.
- Inspect the bottle: no hairline/stress cracks (corners, outlet), no heavy cloudiness or discolouration, no residual smell. A smell means a residue that will not come out.
- Check the cage and pallet: not dented, cracked or rusted through (it carries over a tonne when full). A wooden pallet is cheap but prone to rot.
- Read the data plate: UN approval number, maker, year of manufacture. Without it, re-approval for dangerous goods is practically impossible.
- For dangerous goods, mind the deadlines: inspection intervals and the build-age limit of the plastic inner bottle. Only for water/stationary use? Then those limits do not matter.
- Test the outlet valve and gasket: material to suit the medium — EPDM for water, Viton (FKM) for oil/fuel. Wear parts (standard thread) are more of a negotiating point.
- Budget for cleaning: only professionally reconditioned IBCs count as reliably sealed; too cheap plus an unclear previous content = hidden cleaning costs.
- Plan collection: empty weight is roughly 50–65 kg, footprint about 1200×1000×1160 mm. Trailer/van plus a second person; only ever transport it empty (over a tonne when full).

Is it safe to buy a used IBC?
For rainwater, the garden or non-critical process water, yes — a cleaned or reconditioned used IBC does the job. It is only safe, though, if the previous contents were harmless and documented. Check the label, any UN plate, the bottle (cracks, smell, cloudiness) and the cage. If the previous product is unknown or was a chemical, walk away.
What is the difference between reconditioned and washed?
Washed means the original bottle stays in and is only machine-cleaned — residues can remain. Reconditioned can mean the same, OR a factory-new bottle fitted into the cleaned cage (rebottled). Always ask specifically: new bottle, or cleaned original bottle? That answer decides purity and whether it can carry dangerous goods. See our page on used and reconditioned IBCs for the grades in detail.
How do I know an IBC is food-grade?
Food-grade means the product-contact parts are intended and documented for food contact under the applicable food-contact regulations. In practice that is reliable only with a new or rebottled bottle plus the manufacturer’s declaration, or a demonstrably clean food-only previous use. A merely washed used IBC does not become food-grade by cleaning. See our food-grade IBC page.
Do I need a UN approval for my IBC?
Only for transporting dangerous goods on public roads — and the UN marking has to match your specific product, packing group and gasket; it is not a blanket permit. For stationary use (rainwater, process water, ballast) you do not need a valid UN approval, and an expired one is not a fault — it just lowers the price. The previous contents still have to be harmless. Our UN-code page explains the marking.
Are “free” used IBCs from classifieds worth it?
Genuinely free IBCs exist — it is not a scam. But they are usually uncleaned, with residues of unknown products, sometimes a damaged bottle, and collection only. Fine for water, décor or as a plant trellis; risky for storage, and never for food or drinking water.
Is a 600-litre IBC cheaper than 1000 litre?
Not for saving money: a 600-litre unit costs little less per unit, so more per litre. It is worth it mainly when space or weight is the constraint — for example when the standing area or floor loading will not take the larger container.
Guidance for buyers, not legal or dangerous-goods advice. Approvals, inspection deadlines and storage duties depend on the container’s data plate, its current inspection and, in doubt, an accredited test body — and on the rules of your own country.
