Transporting biological samples requires strict adherence to international safety standards. UN3373 regulations define the correct method for packaging and transporting Biological Substances, Category B to protect handlers, couriers, and recipients. These UN3373 requirements outline the mandatory triple-packaging system, labelling specifications, and testing criteria that ensure samples remain secure, intact, and compliant throughout transit.
At Expert Medicals, we provide fully compliant UN3373 packaging solutions that meet regulatory requirements while ensuring safety, reliability, and efficiency.
What Are UN3373 Requirements?
UN3373 refers to the classification of Biological Substances, Category B materials that are infectious but do not pose a high risk in transport. These shipments must follow the triple-packaging system as set out by the IATA Dangerous Goods Regulations. These UN3373 packaging requirements include:
- Primary receptacle: Leak-proof container designed to hold the sample and withstand pressure changes, temperature variation, and impact.
- Secondary packaging: Also leak-proof, enclosing and protecting the primary receptacle.
- Rigid outer packaging: Strong enough to protect against damage.
Absorbent Layer Requirements for UN3373 Packaging
UN3373 regulations also require the inclusion of absorbent material between the primary and secondary packaging. This material must be able to fully absorb the entire sample volume in the event of leakage.
At Expert Medicals, we supply absorbent pads that exceed absorbency standards, ensuring full containment even in high-volume transport conditions. These pads are tested for rapid absorption to minimise the risk of cross-contamination.
