Planning to export dangerous goods overseas by ship? If your cargo contains flammable, corrosive, explosive, or poisonous materials, it is mandatory to fill out a Dangerous Goods Container Packing Declaration.

According to South African law, cargo ships may not transport or take any packaged dangerous goods on board unless the shipowner or shipmaster is first given a Dangerous Goods Container Packing Declaration form.

Note: You can read more about the South African legal requirements for shipping dangerous goods in the Merchant Shipping (Dangerous Goods) Regulations, 1997, as set out in the Merchant Shipping Act, 1951 (Act No. 57 of 1951).

What are dangerous goods?

For shipping purposes, the International Maritime Organisation (IMO) defines dangerous goods as  “…substances, materials and articles covered by the [International Maritime Dangerous Goods] (IMDG) code”.

The (IMDG) code was first adopted in 1965. The code’s main aim is to prevent all types of sea pollution and ensure human and marine safety. It stipulates how goods must be packaged and transported. The code is universal and contains several mandatory stipulations. This means that all cargo-carrying vessels worldwide must adhere to the majority of requirements set out in the code.

The IMDG code classifies dangerous goods according to their properties. Table 1 provides a summary of these classifications.

What must I indicate on my Dangerous Goods Container Packing Declaration?

Your Dangerous Goods Container Packing Declaration must contain the following information:

  • The correct technical name of the dangerous goods, followed by the words “Marine Pollutant” if appropriate.
  • Universal UN number* (if any) for each good.
  • The class each good belongs to (see Table 1).
  • The number and types of packages.
  • The total quantity of packaged dangerous goods (gross mass or volume).
  • Any additional information required by the IMDG code.
  • A statement to indicate that the goods are packaged in accordance with the regulations set out in the Merchant Shipping (Dangerous Goods) Regulations, 1997.

*UN numbers are four-digit numbers that classify dangerous and hazardous goods in the international transport framework. UN numbers are assigned by the United Nations Committee of Experts on the Transport of Dangerous Goods.

Additional requirements:

  • You must provide the shipowner, shipmaster, or freight forwarder with the declaration. If you make use of a freight forwarder, it is the forwarder’s responsibility to deliver the declaration to the shipowner or shipmaster.
  • If you fail to provide a declaration or provide false or misleading information, you will be guilty of an offence.
