  • TT Club Updates Book it Right and Pack it Tight Guide.
  • Major Changes Cover Batteries and Packing Rules.
  • New TT Briefs Focus on Hazardous Cargo Risks.

The latest update to the International Maritime Dangerous Goods (IMDG) Code, known as Amendment 42-24, will officially take effect on January 1, 2026. In response, TT Club has refreshed its “Book it Right and Pack it Tight” guide and introduced a new series called TT Brief, focusing on hazardous cargoes. It’s crucial to understand that failing to comply with these regulations can lead to serious consequences for people, the environment, and finances, making it a legal and ethical responsibility throughout the supply chain, reports TT.

Key Changes in the Revision

The IMDG Code, created by the International Maritime Organisation and mandatory under SOLAS since 2004, serves as the global standard for transporting dangerous goods by sea. Amendment 42-24 brings over 60 updates to the Dangerous Goods List, introduces 11 new UN Numbers for emerging cargoes like sodium-ion batteries and lithium-powered vehicles, and includes significant revisions to packing instructions and special provisions.

Updated Industry Guidance

In November 2025, TT Club and the UK P&I Club released the latest edition of “Book it Right and Pack it Tight.” This guide provides practical advice on classification, packaging, labelling, documentation, segregation, packing, and certification, along with reference materials on terminology and common challenges.

New TT Brief Series

TT Club has also rolled out a new TT Brief series dedicated to dangerous goods. The inaugural edition, published in November 2025, zeroes in on lithium-ion batteries and is tailored for logistics and transport personnel on the front lines.

Compliance Essentials

Everyone involved in handling dangerous goods must receive proper training as outlined in Chapter 1.3 of the IMDG Code. Each shipment needs to be accurately classified and declared, with the shipper’s declaration holding legal significance. “The person responsible for packing dangerous goods into a cargo transport unit must ensure that goods are correctly named, labelled, segregated and secured. The packing certificate is a legally binding declaration of compliance.”

Additionally, the IMDG Code refers to the IMO/ILO/UNECE CTU Code as the go-to resource for safe container packing. Its checklists, along with the Cargo Integrity Group’s Quick Guide, are designed to promote consistent practices across the industry.
