How does shipping dangerous goods by ocean freight work?

18-09-2025

Shipping dangerous goods by ocean freight requires specialized knowledge, strict regulations and accurate documentation. Dangerous goods include chemicals, flammable liquids, gases and lithium batteries. For exporters and importers, it is essential to have a logistics partner who masters the IMDG code, ADR regulations and international safety standards in detail. Neele-Vat assists customers worldwide with the safe and compliant shipping of dangerous goods.

Context & challenge

Ocean freight is the most commonly used modality for bulk and international shipments, but dangerous goods present additional challenges:

  • Strict regulations - compliance with the International Maritime Dangerous Goods (IMDG) Code.
  • Classification & labeling - proper classification into one of 9 hazard classes.
  • Packaging & marking - packaging must be UN-certified.
  • Documentation - dangerous goods declarations (DGD), safety data sheets (MSDS) and customs papers.
  • Safety & liability - errors can result in fines, delays or safety risks.

Neele-Vat has been organizing ocean freight for dangerous goods worldwide since 1975, in full compliance with laws and regulations.

How does it work?

The process involves several stages:

  1. Classification - determining the correct hazard class and UN number.
  2. Packing & marking - goods are packed in approved packages with labels and pictograms.
  3. Documentation - preparation of Dangerous Goods Declaration (DGD) and MSDS.
  4. Booking - choice of FCL or LCL, depending on volume.
  5. Pretransport - transportation to the port, often by ADR-certified trucks.
  6. Terminal handling - checking and storing containers in accordance with safety regulations.
  7. Ocean freight - shipping according to IMDG guidelines and safety procedures.
  8. Unloading & on-carriage - delivery with compliance with ADR and local regulations.
