For customers in Canada, the United States, the United Kingdom and Mexico, all of our magnetic products are shipped by ground in parcels or LTL. For international customers, we handle all shipments by air for small cargoes or by sea for large quantities. When air freight is required, the magnets must be shipped in accordance with the IATA Dangerous Goods Regulations Packaging Guidelines. If a package has a magnetic flux equal to or greater than 0.002 gauss 7 feet from the package in any direction, the package is considered hazardous and must be removed and marked as "Magnetic Material".
1. Air freight requirements for NdFeB magnets
Air shipment is prohibited if the box containing the magnetic product is greater than 0.00525 gauss, or if a distance of 15 feet from the box in any direction deflects the compass needle by more than 2 degrees. Whether transported by ground or by air, the strong magnetic field is problematic for sorting equipment and aircraft navigation, which is designed for the Earth's 0.5 Gaussian magnetic field. During flight navigation, any directional changes can be dangerous. For each air shipment, we ensure that strong magnetic materials and components are well shielded for their magnetic fields to meet standards, especially for the strongest rare earth neodymium magnets.
We all know that magnets attract steel objects. Therefore, it is important to hold the magnet firmly at a distance from the edge of the package. Filling with air bubbles is not an option as the magnets can move inside the box during shipping. We placed all six sides of the Styrofoam board around the box, leaving zero gaps inside the box and enough space around the magnetic material (magnetic attraction is very sensitive to air gaps, and as decreases sharply as the air gap increases).
2. Packaging of magnets for air transport
If large-sized neodymium magnets with long-range magnetic fields are required, the magnets are packaged and shipped in lined steel boxes to further reduce their magnetic flux. We test and make sure that the compass does not deflect more than 15 degrees at 2.5 feet from the package, and that the shipment does not fall under the "dangerous goods" category, nor does it require additional inspection by the authorities to take special measures to avoid delays or even more big. cost. If it were classified as "dangerous", the package would incur additional expensive shipping charges on top of the high international air freight and of course more paperwork.
Neodymium magnets and neodymium magnets generate a broad and powerful magnetic field, far exceeding that of other magnetic materials. A professional shipping department ensures that every shipment is packed to minimize damage in transit and accurately tested to avoid hazards and penalties from flight authorities.
