It is always the sender's responsibility to ensure that the sample is correctly classified, packaged and labelled and that the correct documents are enclosed with it. In the event of uncertainty regarding the classification, packaging, labelling and transport of samples, contact the safety advisor at your organisation for the transport of dangerous goods.


Classification for transport of dangerous goods comprises substances of various kinds. The substances are divided into various classes based on substance properties and are also allocated a four-digit UN number. The classification and the UN number are important because they provide the starting point for selecting packaging, labelling and documentation.

Category A includes substances that can cause permanent, life-threatening or fatal diseases in humans and animals. Infectious substances affecting humans are assigned UN2814.

Category B includes infectious substances that do not fulfil the criteria for category A. Substances in category B are assigned UN3373.

Human and animal samples where there is minimal likelihood of infectious agents being present may be transported as an "EXEMPT HUMAN/ANIMAL SPECIMEN", in Swedish "UNDANTAGET MEDICINSKT PROV".
