CIMTO assigns UN codes to transport packaging

Our company is entrusted by the Ministry of Transport of the Czech Republic with the testing of design types of packagings, large containers for bulk substances and large packages, the allocation of UN codes to approved design types, the control of the production and use of the above mentioned design types, IBC inspections within time deadlines set by the applicable technical standards, and in accordance with the international transportation regulations. Packaging designed for dangerous goods, in which our service is the most specialized, is very diverse in shape and material used in its production. Their properties are precisely defined in the international regulations for the packaging and transport of dangerous goods. They must conform with the prescribed requirements.

Each design type of packaging has its own code, which characterizes it in its blueprint, and is subsequently a part of the so-called UN CODE, which indicates successfully tested design types of packaging for dangerous goods.
