UN / IIP Certification

Mandatory for manufacturers of packaging material transporting Dangerous goods


Regulatory Compliance that helps you lean in

UN certification, which is mandatory, was introduced primarily for the packages used by Indian Express for carriage of dangerous goods by sea from India.

Similar compulsion was introduced for transportation by air. The packaging certified for utilisation for transport of Dangerous Goods by air shall be checked by the shippers before these are actually used for the purpose. The certified packaging shall have UN marking as indicated in the Certificates, so that only certified packaging is loaded on aircraft.
Dangerous goods may only be transported in packaging which has a UN marking. The UN mark is a globally recognized system established by the United Nations Expert Committee on Hazardous Goods to classify, package, mark, and label dangerous goods for safe transportation by road, rail, sea, and air. Prior to receiving a UN certification mark, testing must be conducted to ensure compliance with the specified standards. The United Nations has enacted various laws, such as the International Maritime Dangerous Goods Code (IMDG), which governs sea shipping and air transportation is governed by the International Civil Aviation Organization (ICAO). Each United Nations member country has the authority to regulate hazardous product transit.
