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.
• Aircraft compatibility: Narrow-body aircraft (e.g., A320) have 1.24-meter cargo holds; undersized packaging risks wall friction.

Reinforcement Solutions

1. Expand packaging: Arrange thin goods horizontally, ensuring widths reach 40% of height (e.g., 0.8m width for 2m-tall items).
2. Triangular brackets: Use lightweight aluminum frames to distribute pressure and enhance shock resistance.
3. Anti-slip design: Add rubber strips to box bases to minimize forklift shifting.
