- UN3373, 'Biologische stof categorie B' of 'Biological Substance, Category B'
An infectious substance not covered by category A is classified as category B ‘.
For air transport (IATA-DGR), the text ‘Biological Substance, Category B’ should be added to the hazard label.
There is an exception for cultures intended for the deliberate propagation of disease processors. These cultures/cultures are covered by UN number 2814 or 2900.
Packaging and labelling
Category B should be packed for transport in accordance with packing instruction P650. This stipulates the following:
1. The packaging should be UN approved and consist of:
- An impermeable container as primary packaging
- A liquid-tight secondary packaging
- For liquids, there must be sufficient absorbent material between the primary packaging and the secondary packaging to absorb the entire contents. Primary receptacles must not come into contact with each other.
- A rigid outer packaging. This must not be smaller than 10 cm.
- Padding material. Each outer packaging must be completely filled with cushioning material so that the secondary packaging is never loose in the outer packaging. The cushioning material must be inert with regard to the substances to be sent.
2.Labelling
A UN 3373 label must be clearly legible on the outer packaging. The size of the label must be at least 5 x 5 cm. The letters and numbers must be at least 6 mm.
The correct transport name is: ‘Biological substance, Category B’. This text should be placed in the immediate vicinity of the label.
For liquids, the directional arrow label should also be placed on the outside on two opposite sides in black or red. This is not required if the primary container is smaller than 50 ml.
3. Highly refrigerated or frozen materials: ice, dry ice and liquid nitrogen.
Primary and secondary packaging must be able to withstand the low temperature and maintain their good condition at both the temperature of the refrigerant used and the temperatures and pressures that may result from the loss of refrigeration.
It is recommended that packaging, labelling and shipping of material with dry ice or liquid nitrogen be outsourced to a specialised company. See under ‘outsource packaging’. This is because there are different requirements for (additional) packaging materials, pressure build-up, labelling and transport conditions.
4. Air transportation
You may only transport or offer dangerous goods for air transport if you hold an accreditation from the Ministry of Transport. This recognition is granted by the Inspectorate for the Environment and Transport (ILT) after training at an institution recognised by the Ministry of Infrastructure and the Environment. www.ilent.nl/onderwerpen/transport/gevaarlijke_stoffen/luchtvaart/erkenningen_gevaarlijke_stoffen/ . With an A-recognition, an institution can itself offer hazardous substances for air transport. If you do not hold an A-recognition, you can still send infectious substances by air by using a company with an E-recognition. Companies with E-approval can act in the place of a private individual, institution or legal entity as sender, taking over full public-law responsibilities. The E-recognition holder then takes care of packaging, labelling, and marking of the hazardous goods, documentation and shipping. In addition, E-recognition holders can provide detailed advice and information on all shipments they handle.
There are two exceptions: Category B biologicals (UN3373) and GMOs (UN3245) do not require an A or E approval, provided they are fully packaged in accordance with the corresponding packaging instructions (P/PI 650 and P904/PI 959).
Furthermore, diagnostic samples covered below may be sent internationally by post according to the postal company's instructions.
