How to Pack Magnets For Shipping Safely Is A Complicated Work.

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.

Let’s find some useful information from IATA regulations:

If the maximum field strength observed at 7 feet is less than .002 gauss, or there is no significant compass deflection, the package is not restricted as “Magnetized Material”.

Above information gives us a clue: if magnet packages past inspection and get an Identification and Classification Report for Air Transport of Goods, then strong rare earth magnet can be sent via air.

How Can We Make a Qualified Magnet Package For Air Transportation?

Into order to past the inspection required by IATA DGR, we need to do some special treatment for magnet package. At present, iron sheet is the main packaging material used for magnetic separation.

There must be a gap between the iron sheet and the magnet. And here can be filled with any non magnetic material as a support like foam.

For larger size magnet, it is difficult to reach total shielding requirements only by a single layer shielding material. We have two other ways to solve this problem.

  1. One is increasing thickness of the iron plate or more iron sheets.
  2. The other is combination of shielding, putting one shielding into another shielding, leaving a certain gap between them.

Magnet for air transportation from China Magnets Source Material Ltd is well packed by iron boxes. And we have excellent professional express forwarders who help us to send magnet safely for many years. So low express cost and fast delivery time are available.

How Can We Make a Qualified Magnet Package For Air Transportation?

Compared to airfreight packaging, the requirements for shipping magnets by sea are relatively simple. Of course, anti-magnetic packaging is still necessary, but the requirements are not as high as air freight packaging. They do not need to do special magnetic inspection. In addition, ocean freight requires plastic wrapping around the outer box for waterproofing.

China Magnets Source can provide wooden pallets and wooden crates for ocean freight magnets. Although wooden cases can hold less magnets than wooden pallets, they are a better choice because powerful permanent magnets can be packed more securely this way.
