UN3373 – Biological Substance Category B Training

Biological substances shipped for diagnostic or research purposes including patient specimens, clinical samples, and laboratory materials that are classified under UN3373, Biological Substance Category B. This classification sits between exempt patient specimens and fully regulated Category A infectious substances, and it has its own specific packing and documentation requirements.

Our UN3373 training course ensures that laboratory technicians, clinical staff, couriers, and freight forwarders understand how to prepare these shipments correctly for carriage by air and road. 

Upon successful completion of this training course, individuals will have an understanding of the rules and regulations governing the transport of Biological Substances, Category B including documentation, packaging and marking and labelling requirements for Biological Substances, Category B.
