UN marking
A dangerous good is any solid, liquid, or gas that can harm people, other living organisms, property, or the environment. They are often subject to chemical regulations. An equivalent term, used almost exclusively in the United States, is hazardous material (hazmat or HAZMAT). Dangerous goods may be radioactive, flammable, explosive, toxic, corrosive, biohazardous, an oxidizer, an asphyxiant, a pathogen, an allergen, or may have other characteristics that render it hazardous in specific circumstances.The European Union has passed numerous directives and regulations to avoid the dissemination and restrict the usage of hazardous substances, the most famous being the Restriction of Hazardous Substances Directive and the REACH regulation. There are also long standing European treaties such as ADR and RID that regulate the transportation of hazardous materials by road, rail, river and inland waterways, following the guide of the UN Model Regulation.
The UN regulation requires a packaging with a UN marking for the shipment of hazardous materials. All CurTec packaging products and some lidded crates have acquired a UN marking for solid hazardous materials after being submitted to a series of drop and stacking tests. A UN marking is physically present on the packaging by means of engraving and is valid for 5 years (ADR chapter 4.1.1.15)
