In addition to complying with the requirements of either the IMDG or IATA, exporters of dangerous goods must comply with land transport requirements for New Zealand and the destination country. Fortunately most land transport codes permit dangerous goods that fully comply with ICAO or the IMDG to be transported by road to the original consignment destination, without having to fully comply with the applicable land transport code. However, in many cases additional conditions apply. If goods are re-consigned they must fully comply with the local requirements. Understanding and complying with the different requirements improves both compliance and safety, and can minimise delays and prevent additional costs, such as repackaging or re-labelling.


The ICAO Technical Instructions apply to air transport of dangerous goods and the IMDG Code applies to sea transport. The Australian Dangerous Goods Code 6th edition (ADG6) was based on the ninth revised edition of the UNRTDG. It is currently being replaced by ADG7, however, each state and territory has to adopt ADG7 independently. At the time of writing ADG6 is still the legal document in many states, and specifies the requirements for land transport. ADG6 permits imported goods to be transported to the initial destination within Australia (providing they comply with either the IMDG Code or ICAO Technical Instructions). The full requirements of the ADG Code apply if goods are reconsigned from a distribution centre or warehouse.

The seventh edition of the ADG Code was published October 2007, however, apart from Western Australia it has yet to be adopted by the states and territories. The seventh edition is closely aligned with the UN Recommendations on the Transport of Dangerous Goods and adopts for the first time ‘Dangerous Goods in Limited Quantities’. This will facilitate the land transport of imported goods. A summary of the major changes can be viewed on the Australian National Transport Commission’s (NTC) website(external link) or on the Chemie Tech website(external link).

It is anticipated that the ADG7 will be adopted by the remaining states and territories in late 2008.

The European Agreement on the International Carriage of Dangerous Goods by Road (ADR) is effective across the European continent, with 40 countries adopting the 2007 edition of the ADR. There has been significant harmonisation with the UNRTDG over recent years, and this is an ongoing process.

Other European Dangerous Goods Codes include the RID governing international rail transport and the AND governing the transport of DG on inland waterways.
