How to Label IBCs Correctly for Safe Handling

An IBC can be the right container and still create a handling or compliance problem if the information on its outer faces is unclear, incomplete or out of date. Knowing how to label IBCs correctly helps warehouse teams identify contents quickly, gives transport operators the information they need, and reduces the risk of a product being stored, loaded or dispatched incorrectly.

For Australian operations, the correct label set depends on what the IBC contains, whether it is classified as a dangerous good, where it will travel and how it is used once it reaches site. A food-grade liquid, a non-hazardous processing chemical and a Class 8 corrosive substance do not carry the same marking requirements. The practical rule is simple: identify the product and its hazards first, then apply the labels, marks and documents required for that use.

Start with the product classification

Before printing or applying anything, confirm exactly what is in the IBC. Use the current safety data sheet (SDS), product specification and transport classification supplied by the manufacturer or chemical supplier. For dangerous goods, this normally includes the UN number, proper shipping name, dangerous goods class or division, any subsidiary risk, and packing group.

Do not rely on a previous label just because the IBC is the same size or came from the same work area. Reused IBCs are a common source of labelling errors. If contents change, old product identification, hazard labels and shipping marks must be removed or fully obscured before the new product is filled.

Where the product is transported by road or rail in Australia, check the current Australian Dangerous Goods Code requirements. If the consignment moves by sea or air, additional international requirements can apply. Your freight provider may also have carrier-specific instructions for label placement, documentation and acceptance.

Separate container markings from product labels

A compliant IBC often carries several types of information. These serve different purposes and should not be treated as interchangeable.

The IBC itself may have permanent manufacturer markings, including its design type, material, manufacture date, maximum stacking load, capacity and UN packaging approval mark where applicable. These markings confirm what the container is designed and approved to do. They do not identify the liquid currently inside it.

A workplace label identifies the product held in the IBC at your facility. For hazardous chemicals, it should align with the SDS and workplace hazardous chemical requirements. This generally means clear product identification, relevant hazard information, and a reference to the SDS or supplier details as required by your site procedures.

Transport labels and marks communicate dangerous goods information to drivers, depots, emergency services and receiving teams. Depending on the classification and transport mode, these can include dangerous goods class labels, UN number marks, proper shipping name, marine pollutant marks or orientation arrows where relevant.

Keeping these categories separate prevents a frequent mistake: assuming that a UN approval stamp or a supplier name on the moulding is enough to send the IBC through the transport chain.

How to label IBCs correctly for workplace use

For day-to-day storage and handling, a label must be readable from a practical working distance. Place it on a clean, smooth section of the outer bottle or protective cage where it will not be hidden by pallet racking, stretch wrap, forklift tynes, discharge valves or lifting points.

The label should identify the product using the same name workers will see on the SDS and inventory system. Avoid vague descriptions such as “cleaner”, “chemical mix” or “waste”. If the product has a site name or batch code, include it as supporting information, but not instead of the correct product identifier.

For hazardous chemicals, ensure the label carries the applicable GHS hazard pictograms, signal word, hazard statements and precautionary information. The exact wording and pictograms are determined by the SDS. Adding extra symbols because they seem safer can cause confusion, particularly where a label does not match the current classification.

Include the date filled or received, batch or lot number, and expiry or review date where these details affect product quality, traceability or safe use. This is particularly useful for agricultural inputs, food-related materials, resins, adhesives, cleaning concentrates and chemicals with shelf-life limits.

Use a site contact or responsible department where staff need to know who controls the product. In larger warehouses, a location code can also help with stock control, but it should never cover mandatory hazard information.

Dangerous goods labels need transport-ready placement

If the IBC is a dangerous goods package for transport, the hazard label and required marks need to remain visible once the container is palletised, loaded and secured. Applying one label beside the outlet valve may work in a staging area, but it can become unreadable when the IBC is placed against another load or wrapped for dispatch.

As a working approach, apply required transport information to at least two opposing sides where the applicable transport rules call for this. Make sure the chosen faces are visible when the IBC is in its normal upright position. Labels should not be folded around cage bars, applied across a curved corner, or placed where abrasion from forks and straps is likely.

The main transport information typically includes the UN number and proper shipping name, along with the relevant class label. Subsidiary risk labels must also be included where assigned. Some substances need further marks, including environmentally hazardous substance or marine pollutant markings. Requirements vary by product, package size, mode of transport and whether an exemption applies, so the SDS alone is not always a complete dispatch instruction.

Do not confuse package labels with vehicle placarding. A correctly labelled IBC may still require a placarded vehicle or transport documentation when the load quantity and dangerous goods rules trigger those obligations. Treat the IBC label as one part of the overall consignment check.

Choose labels that survive the job

A paper office label is rarely suitable for an IBC that will spend weeks in a warehouse, travel on an open trailer, or sit in a yard. Labels need to withstand moisture, UV exposure, chemical splash, rubbing against other freight and normal handling.

For most industrial applications, use durable synthetic label stock with an adhesive suited to the IBC surface. The outer bottle is commonly high-density polyethylene, while the cage is galvanised steel. Adhesive performance can differ between the two, especially where the surface is dusty, oily, cold or textured.

Prepare the application area before fitting the label. Wipe away dust, residue and moisture, then allow the surface to dry. Apply firm pressure across the full label, paying close attention to corners. If the IBC will be exposed to chemicals or weather, consider a printed label system specifically rated for that environment rather than laminating a temporary label by hand.

Legibility matters as much as durability. Use clear contrast between text and background, adequate type size, and print that will not smudge when wet. A barcode or QR code can support inventory control, but warehouse staff and transport personnel must still be able to read essential information without scanning equipment.

Inspect labels at each handover point

Labelling should be checked when the IBC is filled, received, transferred, picked and prepared for dispatch. This is faster than trying to correct a load once it has reached a freight depot or customer site.

A practical inspection should confirm the contents match the label, required labels are present, old labels are removed, and all information is visible and undamaged. Check that stretch wrap, overpacks, straps and pallet corner boards have not covered the label faces. Also confirm the IBC itself remains suitable for use: a faded label is one issue, but a damaged cage, leaking valve or expired packaging approval may stop it being fit for transport.

Where different products are stored in the same area, inspect for segregation requirements as well. Clear IBC labels help operators keep incompatible chemicals apart, but they do not replace a documented storage plan or trained staff.

Common labelling mistakes to avoid

The most costly errors are usually basic ones: dispatching an IBC with a supplier label for the previous contents, using a product name that does not match the SDS, covering hazard information with stretch wrap, or placing labels where they cannot be read from the aisle. Another common issue is treating a workplace label as a transport label and omitting required dangerous goods marks.

Avoid handwritten labels for anything beyond short, controlled internal use. If handwriting is unavoidable during a temporary transfer, make it legible, include the full product identifier and hazard information required by your procedures, and replace it with a durable label promptly.

Before the next IBC leaves your site, stand back and assess it as the driver, receiving operator or emergency responder would. If they cannot identify what it contains and the precautions required within seconds, the label needs attention.
