At Derry Bros we understand the complexities of shipping Hazardous goods. Booking Reservations cannot be “Confirmed” until a hazardous Dangerous Goods Note (DGN) has been approved by the shipping company as correct and compatible to ship. Our highly specialised team have years of experience in dealing with the paperwork and regulations around the shipment of hazardous goods.


Transporting hazardous goods can present a range of dangers including flammability, toxicity and corrosivity. Under the IMDG (International Maritime Dangerous Goods) code all cargo classed as hazardous must be notified at least 24hrs in advance of shipment. This advance notification also helps the shipping operators to plan their load (e.g. so as not to park flammable materials beside explosive materials!). The key objectives of the IMDG code is to protect human life, protect marine pollution and facilitate the free movement of dangerous goods.

According to the code, goods are allocated to one of nine ‘classes’:

Class 1 - Explosives

Class 2 - Gases

Class 3 - Flammable liquids

Class 4 - Flammable solids and other flammable substances

Class 5 - Oxidizing substances and organic peroxides

Class 6 - Toxic and infectious substances

Class 7 - Radioactive material

Class 8 - Corrosive substances

Class 9 - Miscellaneous dangerous substances and articles


With our extensive experience in dealing with the sea transportation of hazardous goods, we can help you navigate the complex paperwork and regulations to help ensure that your hazardous goods reach their destination on time. Given the advance notification period required for these goods, we would always advise that you engage us in your project from the earliest opportunity. Please note that all vehicles carrying hazardous goods must display correct and appropriate number of hazardous labels.
