NdFeB magnets, also known as strong magnets, because the suction is very strong. Therefore, before the magnet is delivered, the packaging of the magnet is particularly important. Most customers need magnets to be magnetized. How to pack the magnetized magnets? Today, we will introduce this issue to you in detail.

1. How to pack the magnets for shipping?

Due to the potentially destructive nature of strong magnetic fields to surrounding items, shipping magnets requires specialized antimagnetic packaging and testing procedures.

The packaging of magnets, the regular size is usually packaged in a white box, which is called a small white box in the industry. The magnet needs to be wrapped in a transparent plastic bag and put into a small white box. There should be no space inside. It is necessary to ensure that the magnet will not shake in the box during transportation. The size, quantity and other information of the magnets should be marked on each small white box

Shipping by sea is usually based on wooden pallets or wooden boxes. This kind of packaging is thick and strong, and ordinary magnet packaging is fine. Usually shipped by LCL container.

Air freight is usually packed in cardboard boxes, and strong magnetic fields are more likely to affect the normal operation of the aircraft. Therefore, magnets need to be packed in cartons, and additional iron sheets are added for magnetic isolation packaging. A magnetic test is required, so how can it pass the magnetic test? The method is very simple, after magnetic isolation packaging, take a utility knife and put it on the outer packaging to test whether there is suction. If there is no general magnetic inspection, it will pass.

2. What reports are required for magnet shipments?

According to the requirements of the IATA902 international air transport agreement, any magnetic field strength 2.1m away from the surface of the tested item should be less than 0.159A/m (200nT) before it can be used for general cargo transportation (general cargo identification). All goods containing magnetic materials will generate a magnetic field in space, and safety testing of magnetic goods is required to ensure flight safety. The full name of the air transport identification is "Identification Report on Air Transport Conditions", and the English name is Identification and Classification Report for Air Transport of Goods, commonly known as air transport identification or identification. Maritime transportation usually requires MSDS. In fact, MSDS is not a test report or appraisal report, nor is it a certification project. It is just a technical manual focusing on safe operation guidelines, which is fundamentally different from the "Air Transport Conditions Identification Report" (air transport identification).

The safety requirements of air cargo transportation are much higher than those of sea transportation, especially when using the belly compartment of passenger aircraft for transportation.

3. Which way is better, to transport the magnets by sea, by air or by international express?

Sea freight, air freight, and express delivery all have their own characteristics. Customers need to choose the best transportation method according to the actual situation of their goods.

Sea freight: low cost, long transit time, but very suitable for goods weighing hundreds of kilograms to several tons.

Air freight: The freight is high, but the transportation time is short. You can choose to pick up the goods at the airport or deliver the goods to your door. It is suitable for 100-200 kg of goods and goods that need to be transported on pallets. It is recommended to choose special line air freight, and the price is more advantageous.

International Express: International fast and flexible, door-to-door, suitable for emergency transportation of goods under 100kg, the delivery time is within 7 days in many countries, and the time limit for remote countries or regions is generally about 15 days.

Magnets are heavy goods, and shipping by sea can greatly reduce the transportation cost; and the freight of express and air freight seems expensive, but compared with the price of magnets, the express fee is not high.

Another important point is that magnets are magnetic products and require magnetic isolation packaging. Many transportation companies do not accept magnetic products for transportation.

If the weight is relatively low, it is recommended to choose international express DHL, FedEx, UPS and TNT for transportation. Magnetic testing is required, and the cost usually does not exceed 500 yuan. For large quantity orders, magnets can be shipped by sea and by air.
