Packing magnets safely is a complex task and generally requires a professional to complete the operation. Super strong magnetic force is the only reason why we should handle magnet carefully.
Although magnets are very common in life, many people still don’t have any idea about the power of NdFeB strong magnets. Even a small magnet may pinch your hand if it is not handled properly, let alone a slightly larger magnet.
At the same time, international transportation of rare earth magnets is carried out by cargo ships and airplanes. Especially for air transportation, strong magnetism can interfere with navigation, electronic equipment and control signals on the aircraft. IATA (International Air Transport Association) classifies magnetic items as Class 9 dangerous goods and restricts them from being transported by air. Therefore ordinary packaging is not suitable for strong magnets.
