Shipping Hazardous Good & Materials Internationally

25 March 2022 | Packaging Guidance

Shipping hazardous materials overseas requires strict adherence to rules and regulations set out by not just American law but also the law from the destination country.

It is the responsibility of the shipper to ensure that all hazardous goods are packaged correctly and safe to ship. If you break any rules during the overseas transportation of hazardous materials then you can be subject to a very hefty fine and possibly even a prison sentence.

In the past, shipping referred to just goods being transported by sea, whereas now the term shipping can be used interchangeably to refer to goods transported by sea, air and road.

Here is some information that you should keep in mind if you need to ship hazardous materials overseas to avoid being penalised.


Shipping hazardous goods by sea

shipping hazardous goods by sea

Hazardous goods can be transported by sea provided that they are packaged, labelled and declared appropriately and that you have completed a valid dangerous goods notification.

The regulatory body in charge of dangerous goods being shipped by sea is the International Maritime Organisation (IMO). They follow practices set out in the latest Safety of Life at Sea (SOLAS) and the International Maritime Dangerous Goods Code (IMDG) to keep everyone safe during the transport of dangerous goods overseas.


Shipping hazardous goods by air

Hazardous goods can be shipped by air provided that the staff performing the packaging are specifically trained and that the goods themselves are packaged, labelled and declared appropriately according to the safe transport of dangerous goods by air from the International Civil Aviation Organisation (ICAO).

The regulatory body in charge of dangerous goods being shipped by air is ICAO however, IATA is the International Air Transport Association (IATA) applicable to specific member airlines, members follow IATA rules where applicable.

When dangerous goods are being shipped by air, you will need to ensure that they are packaged in a container that is not only safe for the hazardous goods specifically being shipped but also packaging that will be able to withstand the pressure of the aircraft at high altitudes, and that a valid declaration for dangerous goods (for air transport) form has been completed.


How to ship hazardous goods

There are many steps that need to be followed when shipping chemicals internationally or sending hazardous goods overseas. These steps begin before you even handle the goods themselves. They are as follows:


You must be aware of the regulations around what hazardous goods you want to ship and how you want to ship them. To export any hazardous goods then you must hold a valid export license.

Hazardous materials are organised across nine classes defined by the United Nations Model Regulations. Each of these will have their own regulations attached to them that you must be aware of before starting the shipping process.



Anybody involved in the package of hazardous goods must have valid, up to date training enabling them to do so safely. If none of your staff can undergo this training then it may be possible for you to hire another company to do this on your behalf.


Classified and declared

Before any hazardous goods can be shipped overseas, the appropriate dangerous goods notes must be completed according to how the items are being shipped and what their dangerous goods classes are.

These notes cannot be completed by just anybody. They need to be completed by a qualified consignor, so that the shipper and the destination country are aware on what they are shipping, what they are receiving, and how they can do so safely.



To ship dangerous goods internationally, you must use fully compliant packaging that is tested, certified and meets the UN requirements for the specific classification of goods being shipped.

Examples of approved packaging materials can be found here.


Labels and documentation

Not only must the materials be packaged securely and appropriately, but they must also be labelled correctly so that it is obvious what is being transported and the dangers of incorrect handling.

This is mostly done using dangerous goods labels and placards.


Transporting limited quantities

This information on how to ship hazardous materials applies to companies who regularly ship hazardous goods internationally by air, sea, or road. If you only transport hazardous materials in limited quantities then you may be exempt from certain packaging and labelling regulations.

See here for more information on the exemptions that come with shipping limited quantities.
