DGR - Dangerous Goods Regulations: What Is It?

What is DGR?

DGR (Dangerous Goods Regulations) are international regulations governing the transport of dangerous goods. It is a set of rules developed by the IATA (International Air Transport Association) that specifies how to safely transport dangerous goods by air. In a broader context, the term DGR is also often used to refer to regulations governing the transport of dangerous goods by all modes of transportation.

The DGR defines nine classes of dangerous goods and specifies requirements for packaging, labeling, documentation, and staff training. These regulations are updated annually to account for new hazards and technologies. Compliance with the DGR is mandatory for all participants in the transport chain—from the shipper through the carrier to the consignee.

Classes of Dangerous Goods According to the DGR

Basic Classification of DGR

Class 1: Explosives – ammunition, fireworks, pyrotechnic materials Class 2: Gases – compressed, liquefied, or dissolved under pressure (propane, oxygen, nitrogen) Class 3: Flammable Liquids – gasoline, alcohol, paints, varnishes Class 4: Flammable solids – matches, sulfur, activated carbon Class 5: Oxidizing Substances and Organic Peroxides – bleaches, certain fertilizers Class 6: Toxic and Infectious Substances – pesticides, medical samples, bacteria Grade 7: Radioactive Materials – medical isotopes, nuclear fuel Class 8: Corrosive Substances – acids, bases, batteries Class 9: Miscellaneous Hazardous Materials – lithium batteries, magnets, dry ice

 

DGR in Various Modes of Transportation

Road Transport – ADR

In road transport, the equivalent of the DGR is the ADR (European Agreement concerning the transportation International Agreement on the Transport of Dangerous Goods by Road (ADR). The ADR applies throughout Europe and sets forth detailed requirements for the transport of dangerous goods by road dangerous goods. At SLAWA sp. z o.o., we are licensed We are ADR-certified and regularly transport selected classes of dangerous goods on international routes.

Maritime Transport – IMDG

The IMDG Code (International Maritime Dangerous Goods Code) regulates maritime freight transport hazardous. Although it is based on the same classes as the DGR, it has specific requirements related to long transport times and maritime conditions.

Rail Transport – RID

RID (Regulations Concerning the International Rail Transport of Dangerous Goods) is transport regulations railway. Like ADR, RID is closely linked to the DGR classification system.

DGR Requirements for Transportation Companies

Training and Certifications

Every person involved in freight Those who handle dangerous goods must complete the appropriate DGR training. Drivers must hold an ADR certificate, freight forwarders must hold a DGR certificate, and warehouse workers must complete training in the handling of dangerous goods. Training must be renewed every 2 years for air transport and every 5 years for a driver's license.

DGR Documentation

Transport in accordance with the DGR requires special documentation:

• Shipper’s Declaration
• Material Safety Data Sheet (MSDS)
• Safety Instructions
• Shipping documents bearing a UN number

Packaging and Labeling

The DGR specifies the requirements for packaging in detail—it must be certified and resistant to transport conditions and labeled in accordance with the regulations. Warning labels, UN numbers, proper shipping names—everything must comply with the DGR.

Practical Applications of DGR

Examples of Goods Requiring DGR Compliance

In everyday transportation practice, the DGR applies to many products that are not always associated with dangerous goods:

• Electronics – cell phones and laptops (lithium batteries – Class 9)
• Cosmetics – nail polish, perfume (Class 3)
• Household items – bleaches, cleaning products (Class 8)
• Car parts – airbags (Class 1), batteries (Class 8)

• Heavy financial penalties (up to several hundred thousand zlotys)
• Criminal Liability in the Event of an Accident
• Loss of a transportation license
• Refusal to Insure the Cargo

Summary

The DGR are key regulations that ensure safety in transportation of dangerous goods. Whether we are talking about air transport (IATA DGR), road transport (ADR), maritime transport (IMDG), or rail transport (RID), the basic principles remain the same—proper classification, packaging, labeling, and documentation.
