Adding value with our service portfolio


More countries now demand that dangerous imported goods be packaged properly and safely to withstand harsh conditions during shipping and transportation. Countries such as the United States, Europe, Canada, Japan and Australia require such imports to meet the safety levels outlined by the United Nations Recommendations on the Transport of Dangerous Goods.

UN mark is a universal / international system created by the United Nations, which is meant for the classification, packaging, marking and labelling of dangerous goods, in order to transport it safely (by road, rail, sea and air). Testing are required to be carried out, before a UN certification mark can be issued. The packaging must meet or exceed minimum standards of performance before it can be used.

TÜV SÜD is able to test and certify your packaging products to UN requirements.
