Class 5 hazard labels are used to identify oxidising substances and organic peroxides classified as dangerous goods during transport. These materials can intensify fires, release oxygen, react violently with other chemicals or decompose rapidly, creating significant risks during handling, storage and shipment. Common examples include hydrogen peroxide solutions, nitrates, chlorates, peracetic acid, ammonium persulphate and various industrial oxidisers.
To ensure safe handling and regulatory compliance, Class 5 is divided into two divisions, each representing a specific type of hazard:
• Divisions5.1 – Oxidising Substances: Materials that release oxygen and can greatly accelerate combustion, such as sodium nitrate, potassium permanganate and many industrial oxidisers.
• Divisions 5.2 – Organic Peroxides: Thermally unstable substances that may undergo exothermic decomposition, sometimes explosively. Examples include MEKP, benzoyl peroxide and various polymerisation catalysts.
Each Class 5 label features the appropriate hazard symbol, the division number (5.1 or 5.2) and the standardised colour background: yellow for oxidisers and red/yellow for organic peroxides. These labels are mandatory for compliant transport under IATA/DGR, ADR, IMDG, ADN and RID regulations, ensuring clear identification across air, road, sea, rail and inland waterways.
Class 5 labels are essential for chemical distributors, industrial suppliers, laboratories, warehouses, logistics operators and any business handling or shipping oxidising substances or organic peroxides.
We offer Class 5 labels in polypropylene (100×100 mm and 100×135 mm) and vinyl placards (250×250 mm and 300×300 mm), available with text, without text or customised on‑demand printing. Packs of 10, 50 and 100 units are available, as well as rolls of 250, 500 and 1000 to support all dangerous goods operations.
