Obligations of Shipper, Carrier and Consignee in Dangerous Goods Transport
Transport of dangerous substances in shipping containers represents an absolutely fundamental, yet highly risky area of global logistics. Modern commerce is unthinkable without it – shipping containers annually transport millions of tons of industrial chemicals, fuels, medical materials, explosives and radioactive isotopes. Every wrong step in the chain from shipper to consignee can have fatal consequences: endangering human lives, environmental disasters and billion-dollar property damage.
Obligations in dangerous goods transport are therefore not only a matter of law, but also a basic condition for participation in global trade. The entire process is built on strict international standards, regularly updated based on technological progress and experience from real incidents.
The main pillars include:
- IMDG Code (International Maritime Dangerous Goods Code) – the key code for maritime transport of dangerous substances in containers.
- ADR (European Agreement concerning the International Carriage of Dangerous Goods by Road) – binding for road transport in Europe.
- RID (Regulations concerning the International Carriage of Dangerous Goods by Rail) – for the rail segment.
- UN Model Regulations (Orange Book) – the basic UN model regulation from which all other codes derive.
Safety is ensured by linking legislation, standardized technical requirements, harmonized processes and thorough training of all participants in the transport chain.
Why is strict regulation indispensable?
Transport of dangerous materials is associated with extreme risks:
- Flammable substances can explode or cause fire.
- Toxic substances can poison crew, animals and ecosystems.
- Corrosive substances destroy containers, equipment and biological tissues.
- Radioactive materials can cause permanent contamination.
- Explosives have the potential to cause loss of life and total destruction of infrastructure.
Regulations therefore protect:
- human lives on ships, in ports and in the vicinity of transport routes,
- property of carriers, manufacturers and customers,
- the environment from long-term consequences of accidents,
- smooth operation of world trade through unified rules.
For example, incidents such as the container explosion on the ship YM Mobility in August 2024 demonstrate how fatal the consequences of failure of even just one part of the system can be.
Classification of dangerous goods and key concepts
9 classes of hazard
Each substance, mixture or product is classified into one of nine classes according to its main risk:
| Class | Name | Examples | Key Risk |
|---|---|---|---|
| 1 | Explosives | Explosives, pyrotechnics, ammunition | Explosion, detonation, fire |
| 2 | Gases | Propane, acetylene, oxygen, chlorine | Flammability, toxicity, pressure explosion |
| 3 | Flammable liquids | Petrol, ethanol, paints | Ignition, vapors, fire |
| 4 | Flammable solids | Sulfur, white phosphorus, carbide | Self-ignition, gas evolution |
| 5 | Substances supporting combustion, peroxides | Ammonium nitrate, peroxides | Oxidation, self-ignition, explosion |
| 6 | Toxic and infectious substances | Cyanides, pesticides, biological samples | Poisoning, infection |
| 7 | Radioactive materials | Medical isotopes, uranium, plutonium | Ionizing radiation |
| 8 | Corrosive substances | Sulfuric acid, sodium hydroxide | Corrosion, erosion |
| 9 | Other dangerous substances and articles | Lithium batteries, asbestos, dry ice | Various specific risks |
Identification of goods includes:
- UN number: four-digit code for each substance/group (e.g. UN 1203 for petrol).
- Proper Shipping Name (PSN): e.g. PETROL – always in English.
- Packing group (PG): PG I–III according to degree of hazard (I = highest, III = lowest).
- Safety labels and placards: diamond labels (100×100 mm), large boards (250×250 mm) on the container.
Technical and certification requirements for containers and packaging
Why is certification key?
- Verification of technical condition: Every container for dangerous goods must be regularly inspected for strength, tightness, corrosion resistance and mechanical damage.
- UN certification of packaging: Packaging must undergo strict tests (drop, hydrostatic, stacking, tightness) and be marked with UN code.
- Correct marking: Without visible and correctly placed labels and placards, the container cannot be loaded onto a ship, train or truck.
Consequences of non-compliance with certification
- Legal liability and fines: Non-compliance can mean insurance invalidity and high penalties.
- Seizure and confiscation of shipment: Port or customs authorities may detain or return non-compliant shipments.
- Increased risk of accident: A damaged or incorrectly marked container is a common cause of leakage, fire or explosion.
Obligations in the transport chain – detailed analysis
Obligations of the shipper (Shipper/Consignor)
The shipper is the first and most responsible link in the chain – any error in their procedure is often impossible to correct in subsequent phases.
Classification and documentation
- Correct determination of class, UN number, PSN and PG – based on the Safety Data Sheet (SDS) and current versions of IMDG Code/ADR.
- Completion of Multimodal Dangerous Goods Form – the main document where the shipper signs that the shipment complies with all IMDG Code requirements and applicable laws.
- Attachment of other mandatory documents depending on the type of goods (e.g. radiological certificates, packaging test certificate, export/import permits, if required by legislation).
Packaging and marking
- Use of only UN certified packaging corresponding to the packing group.
- Inspection of packaging integrity and correct closure.
- Marking of each package (labels, UN number, PSN, possibly Kemler hazard number for ADR).
- Placement of large placards (placards) on all four sides of the container according to the prevailing class of hazard.
Loading and securing
- Correct loading and securing of cargo (against movement, tipping and leakage).
- Segregation of incompatible substances – e.g. separation of oxidizing agents and flammables according to IMDG Code.
- Completion and signing of Container Packing Certificate (CPC) – mandatory document on correct packing and securing.
Other obligations
- Ensuring delivery of all documentation to the carrier and informing the consignee of the nature of the shipment.
- Timely notification of any changes or incidents during transport.
Obligations of the carrier (Carrier)
The carrier (shipping company, freight forwarder) takes over the shipment and is responsible for its safety for the entire time it is under their control.
- Verification of completeness and correctness of documentation upon receipt – any discrepancies must be resolved immediately, otherwise the carrier must not accept the shipment.
- Planning of stowage on the ship (stowage plan) – strict compliance with segregation according to IMDG Code, distance from crew, engine rooms, sensitive equipment, etc.
- Provision of fire-fighting and safety systems on the ship, including crew training in handling dangerous substances and emergency procedures.
- Provision of information to port authorities and other links in the chain.
- Maintenance of records on movement and condition of dangerous shipments.
Obligations of the consignee (Consignee/Receiver)
- Timely receipt of the container and ensuring its safe transport to their premises.
- Inspection of external condition, marking, seals and any signs of leakage upon receipt.
- Safe unloading only by trained personnel with access to all documents and information about the nature of the goods.
- Removal of placards after cleaning and decontamination of the empty container – an empty container still marked as dangerous is a serious violation of regulations.
Regulatory framework and harmonization of rules
UN Model Regulations (Orange Book)
- Foundation of all regulations: classification, marking, testing, documentation, packaging.
- Regular updates based on technological development and incidents.
- Not directly binding, but all international codes derive from it.
IMDG Code
- Legally binding for all states that are signatories to SOLAS (Safety of Life at Sea).
- Updated every two years – latest version IMDG Code 41-22.
- Contains detailed rules for packaging, marking, documentation, segregation and training.
ADR, RID, ADN
- Harmonize rules for road, rail and inland waterway transport in Europe and surrounding areas.
- Enable smooth transition of containers between different modes of transport and countries.
National regulations
- Each country may have supplementary or stricter requirements (e.g. USA – Title 49 CFR).
- It is worthwhile to monitor current legislative changes in transit and destination countries.
Special cases and exceptions
Limited Quantities (LQ)
- For small inner packages, simplified requirements apply for documentation, marking (special LQ label instead of placards).
- The container, however, still falls under inspection and must meet technical standards.
Excepted Quantities (EQ)
- Even greater relief for very small volumes – use e.g. in healthcare.
Transport of hazardous waste
- Subject to not only transport but also environmental regulations (Basel Convention).
- Requirements for documentation, permits and consent of the destination country are often stricter.
On-site transportation
- Movement of dangerous substances within one company or port – milder rules, but still mandatory training and marking.
Risk management, incident prevention and modern technology
Training and competence
- Every employee who handles dangerous goods (loading, documentation preparation, transport, unloading) must undergo regular training according to IMDG/ADR.
- Training varies depending on specific role (e.g. driver, warehouse worker, administrator, ship captain).
Communication and transparency
- Continuous exchange of information between shipper, carrier and consignee is essential for preventing misunderstandings, errors and accidents.
Technology
- Automated systems for documentation verification and container tracking.
- Temperature and container integrity monitoring (especially for sensitive substances).
- Modern emergency plans and simulation software to identify risk scenarios.
Emergency preparedness
- Mandatory plans for procedures in case of leakage, fire, explosion or other accident.
- Availability of personal protective equipment, emergency kits, fire extinguishers or neutralizing agents.
Conclusion
Transport of dangerous goods in shipping containers is a complex process governed by detailed standards and divided among several responsible entities – shipper, carrier and consignee. Each of them must know their role, monitor current changes in regulations and consistently ensure employee training, technical condition of packaging and containers, correct documentation and marking.
It is not just about bureaucracy – human lives, the environment and the safety of the entire global trade system are at stake. Consistent fulfillment of obligations is essential for accident prevention, damage minimization and maintaining confidence in international logistics.
