Other labels to look out for

If you spot any of the labels shown below on the items you want to ship, you'll need to get in touch with us.

If you're not sure whether your shipment is dangerous goods or not, ask the manufacturer or supplier for a Material Safety Data Sheet (MSDS). If it contains a UN number, it's dangerous goods. Alternatively, you can just contact us.

Examples of dangerous goods

Some goods that are classified as hazardous materials may surprise you, such as aerosols, perfume or anything containing lithium batteries – like phones or laptops.

Lithium batteries

If packed incorrectly or damaged in transit, lithium batteries can short-circuit, causing them to overheat and catch fire.

Sprays and aerosols

The compressed gas that makes these items work is hazardous and can explode if packed incorrectly.

Paints and varnishes

Oil-based paints, spray paints and some varnishes can overheat and catch fire in certain conditions.


Alcohol, which is a flammable substance, is also a crucial ingredient in almost all perfumes and colognes.
