Unit Load Devices (ULDs)-aircraft containers or pallet-and-net systems-are critical for securing cargo, mail, and baggage during air transport. Since the 1950s, ULDs have been a leading source of ground damage, costing the industry approximately USD 400 million annually.
In response, IATA has developed the Unit Load Device Regulations (ULDR)-a comprehensive manual covering all technical, operational, and regulatory aspects of ULDs. The ULDR standardizes requirements for manufacturing, repair, handling, and safety, with the goal of reducing incidents and streamlining compliance across the supply chain.
Aircraft Unit Load Devices (ULDs) encompass both aircraft containers and combined aircraft pallet-and-net systems used to group and restrain cargo, mail, and baggage for air transport. Since the 1950s, these devices have enabled the safe movement of freight by air. Yet year after year, ULDs remain a primary cause of aircraft ground damage, generating roughly USD 400 million annually in repair costs and operational losses for the industry.
Incompatibilities between pallets and nets, outdated training protocols, and inconsistent handling standards continue to undermine air cargo safety, resulting in USD 400 million in ULD-related ground damage and losses each year. To address these challenges, IATA has released the 2026 edition of the Unit Load Device Regulations (ULDR), incorporating technical updates across multiple sections of the manual.
"Several updates have been made to the ULD Regulations," stated Liao Zhiyong, IATA's Senior Manager for Cargo Safety and ULD, in a video introducing the new edition. These revisions support standardized ULD operations on the main deck of the new Airbus A350 freighter and promote safer, more consistent operational practices industry-wide.
New Aircraft Profiles and ULD Type Codes: "Updated aircraft profile information has been added to Part 2," he explained. "Section 4 introduces the new aircraft container profile code W, creating the new ULD type code AMW."
Engine Transport Vehicle Standards Update: "Section 6 will update Operational Practice 6/12-Aircraft Engine Transport-to align with ICAO Technical Instructions Appendix L," he confirmed.
Training and Assessment Reform: "Following the successful adoption of competency-based training and assessment methods two years ago," Liao noted, "the 2026 edition introduces a new matrix template focused on ULD build-up functionality."
New Sustainability Guidance: "To support IATA's cargo sustainability initiatives, a new Appendix J will be introduced, providing guidance on ULD lifecycle assessment."
These changes are designed to bring clarity and structure to ULD operations in complex, high-risk environments. As fleet diversity increases, cargo profiles evolve, and regulatory pressures intensify, the 2026 ULDR provides a clearer framework for compliance.
