Consignment / Shipment notification

Transport in the UK by Sea or Air

There are similar international requirements based on SSR-6 applicable to sea and air transport namely the International Maritime Organisation's International Maritime Dangerous Goods (IMDG) Code and the International Civil Aviation Organisation's (ICAO) Technical Instructions for the Safe Transport of Dangerous Goods by Air. These are implemented in the UK by The Merchant Shipping Act 1995, The Merchant Shipping (Dangerous Goods and Marine Pollutants) Regulations 1997, The Air Navigation Order 2016 and The Air Navigation (Dangerous Goods) Regulations 2002.

In accordance with Agency Agreements (legal documents used to transfer statutory responsibilities between bodies) ONR also receives Consignment Notifications on behalf of other civilian United Kingdom (UK) Competent Authorities; namely:

  • The Competent Authority of the United Kingdom of Great Britain and Northern Ireland in respect of sea transport, being the Secretary of State for Transport including the Maritime and Coastguard Agency;
  • The Competent Authority of the United Kingdom of Great Britain and Northern Ireland in respect of air transport, being the Civil Aviation Authority;

The following notifications for transport of class 7 goods by sea or air may be sent to ONR using the details at the bottom of the page:

  • IMDG Code & by sea
  • ICAO Technical Instructions Part 5, by air
