Dangerous goods
Materials classified as posing a transport risk, governed in Australia by the ADG Code.
What is a dangerous goods?
Dangerous goods are substances and articles classified as posing an immediate risk to people, property or the environment during transport, such as flammable liquids, corrosives, oxidisers and compressed gases. In Australia, road and rail transport of dangerous goods is governed by the Australian Dangerous Goods Code, which assigns each material a UN number, a class and division, a packing group and a proper shipping name, and sets the packaging, marking, placarding and documentation each requires. Edition 7.9 of the Code has been mandatory since 1 October 2025. Classification is the consignor's legal duty, not the carrier's and not an intermediary's: the party sending the goods must classify them correctly, pack and mark them accordingly, inform the carrier, and provide a compliant transport document. Being classified as dangerous goods does not make a material unsaleable; it determines how it must be packed, documented and moved.
How Surply uses it
Surply records the dangerous-goods status the seller declared and stamps the ADG edition it was assessed under, so listings can be re-validated when the Code changes rather than going quietly stale. Surply never classifies a material itself.
