As a designer and manufacturer of Category A and Category B compliant packaging for over 25 years, Intelsius is well-positioned to offer the best packaging solutions to ship dangerous and infectious substances. The United Kingdom recently discovered its first human case of influenza A (H1N2)v or human swine flu. This strain of the virus is not genetically related to any of the previous 50 cases detected globally since 2005.

This short article will highlight how you can safely ship samples of H1N2, otherwise known as an infectious substance.

A simple breakdown of the UN classification of infectious substances is as follows:

Category B is known as UN3373 and is described as: ‘an infectious substance which does not meet the criteria for inclusion in Category A.’

Category A is divided into two sub-categories: UN2814 (affecting humans) and UN2900 (affecting animals only) and is described as: ‘an infectious substance which is carried in a form that, when exposure to it occurs, is capable of causing permanent disability, life-threatening or fatal disease in otherwise healthy humans or animals.’

The difference between Category A and B compliance can be found here, including various transport regulations and packaging requirements.

A H1N2 sample could fall under either a Category A or B infectious substance, however Intelsius have solutions that can cater to either category.
