UN3373 Compliant Transport Box – Rigid Outer Packaging

When transporting vials, tubes, or vacutainers containing diagnostic samples, the Expert Medicals UN3373 transport box offers a robust, compliant, and secure solution.

Specifically engineered to meet Category B Biological Substance (UN3373) transportation requirements, our rigid transport box has been designed with enhanced durability and integrated security features. It complies fully with Packing Instruction P650, and adheres to both ADR and IATA regulations, ensuring legal and safe shipment of diagnostic materials.

Compliant UN3373 Packaging for Diagnostic Sample Transport

In line with international guidelines, diagnostic samples must be packaged using a three-layer system to ensure containment and safety:

• Primary Receptacle(s) – such as a vial, tube, or vacutainer
• Secondary Packaging – leakproof and absorbent to protect in case of breakage
• Rigid Outer Packaging – durable and impact-resistant

Our UN3373 transport box serves as the rigid outer layer, built to protect contents against shocks, vibration, pressure changes, humidity, and temperature fluctuations during courier transit.

UN3373 Outer Packaging Requirements

To meet UN3373 regulations, the outer box must:

• Be strong enough to endure typical handling and drop conditions
• Have at least one surface measuring 100mm x 100mm (4” x 4”) for proper labelling
• Withstand static loads—our boxes are tested to endure up to 80kg of compression force

Compact yet exceptionally strong, our transport boxes are trusted by healthcare providers, laboratories, and diagnostic networks to maintain sample integrity from collection point to testing facility.
