Guangzhou Airport enforces strict packaging rules for uniquely shaped cargo. For example, narrow items over 1.5 meters tall (e.g., glass panels, metal racks) require packaging widths exceeding 1/3 of their height to prevent tipping. Non-compliant shipments must widen boxes or add triangular brackets for stability.
Why the 1:3 Ratio?
Mechanical balance: A 1:3 width-to-height ratio reduces tipping risk by 70%, aligning with IATA’s Dangerous Goods Regulations.
