Are you compliant without dangerous goods documentation?

Your shipment is packed, labelled and ready to go. Everything looks correct.

But then the shipment is put on hold, because the carrier flags it. Not because of the goods themselves, but because something is missing in the paperwork. “What now?”

Situations like this are more common than you might think. In many cases, it is simply not clear which documents are actually required for a shipment.

In this guide, we walk through the most important dangerous goods shipping documents, when they are required and how they fit into your shipping process.

Why documentation matters in dangerous goods shipping

When shipping dangerous goods, documentation is not just administrative work. It ensures that everyone involved in the transport chain understands what is being shipped and how it should be handled.

Carriers, terminals and authorities rely on these documents to assess risks and verify compliance.

If information is missing or incorrect, shipments can be delayed, rejected or flagged for inspection.

What documentation is required for dangerous goods shipments?

The exact documents depend on the mode of transport and the type of goods. However, most shipments rely on a combination of standardised documents.

The key is not just knowing which documents exist, but when each one is required.

Dangerous goods transport document

The dangerous goods transport document is one of the most commonly used documents, especially in road (ADR).

It includes essential shipment details such as:

• UN number and proper shipping name
• one of the nine dangerous goods classes
• packing group
• quantity and type of packaging

This document travels with the shipment and ensures that all parties have access to the same information.

Air and sea freight documentation

For air and sea transport, documentation requirements are stricter and more formalised than for road transport.

In air freight (IATA), a formal declaration is required to confirm that the goods have been correctly classified, packed and labelled. This document is typically referred to as the shipper’s declaration for dangerous goods.

In maritime transport (IMDG), similar information is required but usually provided through documents such as the dangerous goods note (DGN). These are designed for port and terminal operations and ensure safe handling during loading and unloading.

While the names and formats differ, the purpose is the same: to clearly communicate the risks and handling requirements of the shipment across the transport chain.

Multimodal dangerous goods form

When shipments involve multiple transport modes, such as a combination of sea and road, the multimodal dangerous goods form is often used.

It standardises the required information across different stages of the journey and ensures consistency between carriers.

This is particularly relevant for international shipping, where goods move through multiple checkpoints.

How to choose the right documents

There is no single document that applies to every shipment, and there’s also no single tool that tells you exactly which documents you need.

The required documentation depends on a combination of factors:

• the mode of transport (road, air or sea)
• the type of dangerous goods (UN number)
• the countries and carriers involved
• the role your business plays in the shipment (shipper, consignee, fulfilment provider, label creator etc)

Most businesses define this once for their specific setup and reuse it for recurring shipments. For new or more complex shipments, it is common to validate documentation requirements with logistics partners, carriers or specialised training or consulting providers.

Common mistakes in dangerous goods documentation

Many issues in dangerous goods shipping are caused by small but critical mistakes in documentation.

These include:

• missing or incomplete shipment details
• using the wrong document for the transport mode
• inconsistencies between documents
• outdated templates or formats

These errors often only become visible once the shipment is already in transit.

Build a reliable documentation process

Instead of treating documentation as a last step, it should be part of your standard shipping workflow.

This means defining which documents are required per shipment type, standardising templates and processes, ensuring consistency across teams and systems.

By structuring your documentation process properly, you reduce errors, avoid delays and make your shipping operations more predictable.
