When it comes to transporting magnetic materials, specialized packaging methods are essential. Depending on the mode of transportation, such as sea freight or air freight, different considerations apply. For sea freight shipments, standard packaging that provides protection against impacts and collisions is generally suitable. However, for air freight, adherence to international air transport packaging standards, including magnetic shielding, is necessary. It’s important to note that different airlines may have specific requirements regarding the external magnetic field strength of magnetic material shipments. Additionally, obtaining a valid magnetic testing report from the airline is crucial to ensure compliance and avoid any potential transportation issues.
Magnetic shielding packaging is commonly employed, involving the use of iron plates, foam, or wooden boards placed within the cardboard box. After completing the shielding packaging, the magnetic field strength of the outer box can be measured using a Gauss meter to verify compliance with transportation standards. In the absence of a Gauss meter, a simple test using a paperclip can provide a preliminary assessment. If the paperclip is not attracted to any part of the outer box, including the edges and corners, the shielding packaging is deemed sufficient.
We welcome any inquiries or suggestions regarding magnetic material shielding packaging or alternative testing methods. Open discussions are encouraged to further explore and improve these practices.
