The UN Marking System for Agrochemicals - Pesticides, Insecticides, Weedicides, Fungicides, herbicides and Fertilizers

The U.N. marking system indicates several characteristics of the packaging, as well as information on the test levels the packaging has successfully passed. Because these test levels are related to the hazard level and physical and chemical characteristics of the substance to be filled, the markings also indicate some of the properties of the materials that may be packed in each container.
