IATA DGR & IMDG Code Lithium Battery Regulations for Air and Sea

Air Transport

IATA Dangerous Goods Regulations (DGR)

The International Air Transport Association (IATA) Dangerous Goods Regulations, universally known as IATA DGR, is the global standard for the safe transport of dangerous goods by air. It is updated annually and is more restrictive than any other transport mode regulation for lithium batteries.

IATA DGR is technically derived from the ICAO Technical Instructions for the Safe Transport of Dangerous Goods by Air, but incorporates additional airline and freight operator restrictions. Compliance is a legal requirement for any party tendering dangerous goods to airlines, freight forwarders or ground handling agents.

For lithium batteries, IATA DGR defines two tiers of compliance:

  • Section II, Applies to small quantities of lithium batteries (e.g. consumer electronics). Simplified requirements.
  • Section I, Applies to larger quantities and standalone battery shipments. More stringent packaging, marking, labelling and documentation requirements.

Damaged, defective and recalled batteries are subject to the most restrictive provisions in IATA DGR and require packaging equivalent to UN P911 performance. BUNCKER® satisfies these requirements in full.

IATA Packing Instructions for Lithium Batteries

PI Battery Type Configuration
PI 965 Lithium ion Standalone batteries
PI 966 Lithium ion Packed with equipment
PI 967 Lithium ion Contained in equipment
PI 968 Lithium metal Standalone batteries
PI 969 Lithium metal Packed with equipment
PI 970 Lithium metal Contained in equipment

BUNCKER® satisfies the packaging requirements applicable to damaged and defective batteries under all packing instructions (PI 965–970), including Section I provisions.

Sea Transport

IMDG Code for Sea Transport

The International Maritime Dangerous Goods (IMDG) Code is the mandatory framework for shipping dangerous goods by sea, issued by the International Maritime Organization. It applies to all vessels engaged in international voyages carrying packaged dangerous goods as cargo.

The IMDG Code is updated biennially and incorporates changes from the UN Model Regulations, ensuring alignment with ADR and RID wherever possible. For lithium batteries, classified as Class 9, the IMDG Code has progressively tightened requirements over successive amendments.

Amendment 41-22 (current edition) includes specific provisions for:

  • Damaged, defective and recalled lithium batteries, requiring P911-equivalent containment
  • State-of-charge restrictions for batteries transported by sea
  • Enhanced stowage and segregation requirements for battery shipments
  • Documentation requirements aligned with the UN Model Regulations

BUNCKER® meets all IMDG Code requirements for Class 9 lithium battery sea transport. Our units are suitable for container shipments, RoRo vessels and general cargo operations.

Rail Transport

RID: Regulations Concerning the International Carriage of Dangerous Goods by Rail

RID (from the French: Règlement concernant le transport International ferroviaire des marchandises Dangereuses) is the international framework for transporting dangerous goods by rail. It forms Appendix C of the Convention Concerning International Carriage by Rail (COTIF) and is legally binding for all COTIF contracting states across Europe, the Middle East and North Africa.

RID is maintained and updated jointly with ADR by the Working Party on the Transport of Dangerous Goods (WP.15) of the UNECE. As a result, RID and ADR share the same classification system, packaging requirements, marking conventions and documentation standards, with only minor mode-specific variations. Packaging certified for ADR road transport is simultaneously suitable for RID rail transport, without the need for separate testing or certification.

For lithium batteries, RID 2025 applies the same Class 9 provisions, Special Provisions and packaging instructions as ADR 2025, including the requirement for P911/LP906 packaging for damaged, defective and suspected batteries under Special Provision 376. BUNCKER® is compliant with RID 2025 and updated in parallel with each ADR edition.

The practical significance: if your supply chain involves road-to-rail transfers, for example, connecting European distribution centres with rail freight corridors, you do not need to repackage between modes. One BUNCKER® unit, one set of documentation, one certification. Road to rail and back again.

Overview

IMDG Amendment 41 Sea IMO Biennial Certified
IATA DGR 65th Edition Air IATA / ICAO Annual Certified
RID 2025 Rail OTIF / UNECE Biennial (with ADR) Certified
Operational Advantage

One Package: All Transport Modes

The ability to ship a single packaging unit across all four transport modes is not a convenience feature, it is a significant operational and commercial advantage for any company managing complex lithium battery logistics.

Traditional approaches require separate packaging solutions for each mode: one certified for road, another for air, a third for sea. Each requires separate documentation, separate training, separate stock management and separate audit trails. The administrative overhead alone is substantial.

BUNCKER® eliminates this complexity entirely. A single unit, certified once, covers the complete journey, from road pickup to sea freight to final-mile road delivery, or from road collection to air cargo to inland distribution. No repacking. No re-certification. No additional documentation per mode.
