Magnets can be an extremely dangerous cargo item to ship internationally or domestically. Domestically, magnets are being deregulated. But with that said the packaging requirements for shipping these extremely sensitive and dangerous cargo items are strictly mandated and strictly enforced by the government. Contracted engineering company’s that will be dealing with the outsourcing of the magnetism of the items being shipped must follow the International Air Transport Association (IATA) Dangerous Goods regulations in order to comply with the FAA and the International Civil Aviation Organization (ICAO) requirements for shipping magnets by air internationally or domestically.
When shipping anything that holds a magnet charge by air, one must first understand the classification and definition of “Magnetized Material” as given by the Federal Aviation Administration (FAA) or the International Air Transport Association (IATA). This is important because this could determine a price difference and a capability change. For instance if the cargo item has a magnetic field strength of 0.159 A/m (0.002 Gauss) or more at a distance of 2.1 m (7 ft) from any point on the surface of the assembled package, then the item is considered magnetic material to the point that it must be packaged separately and differently. Secondly, the packing instructions are important when dealing with magnetic material. Magnetized material is to only be accepted under the conditions that the cargo items, such as magnetrons and meters, have been packed so that the polarities of the individual units oppose one another and do not affect one another. Permanent magnets must have keeper bars installed to be properly accepted by any outside organization. And lastly, for proper acceptance, the packaging must denote that the magnetism does not exceed 0.418 A/m (0.00525 gauss) or must produce a magnetic compass deflection of 2 degrees or less.
The Federal Aviation Regulations require that all personnel packaging any magnetically dangerous cargo good, item or article, especially magnets, are to be trained to package the items in a proper manner. Training records must be maintained to document that initial, follow-on and refresher training is being accomplished in the proper intervals as applicable. Objective evidence will be required to ascertain the effectiveness of training and the training program alike to the Federal Aviation Administration.
To ensure the prompt and continuous following of their rules the Federal Aviation Administration (FAA) imposes strict penalties for violations. With all the rules and regulations dealing with the process of moving magnetic cargo internationally or domestically, magnetic fields in air-space are minute to minimal keeping it extremely safe to fly.
