As a magnet assembly manufacturer ,We are often asked about shipping magnets by air, and thought we’d take a minute to write about it.
How to Ship Magnets by Air
Shipping magnets by air can indeed be challenging due to the potential risks they pose to aircraft systems. The primary concern revolves around Electromagnetic Interference (EMI), which can disrupt avionics, communication systems, and other sensitive electronic equipment on airplanes. Because of these risks, strict regulations are in place to ensure that magnets are transported safely without interfering with critical aircraft operations.
To provide more specific guidance on shipping magnets by air, here are the detailed steps and considerations to ensure compliance with safety regulations:
1.Measure Magnetic Field Strength
- Before packaging, measure the magnetic field strength of each item to be shipped.
- Ensure that the magnetic field strength of the package does not exceed 0.00525 gauss (0.5 milligauss) when measured at a distance of 15 feet (4.57 meters) from any point on the package. This measurement ensures the magnetic field is weak enough not to interfere with aircraft navigation and communication systems.
2.Use Proper Shielding
Shielding Materials:
Use appropriate shielding materials to contain the magnetic field. Common materials include steel plates or other ferromagnetic materials that can absorb or block magnetic fields.
Double-Wall Containers:
Consider using double-wall containers with magnetic shielding placed between the walls. This setup helps to prevent the magnetic field from escaping the container.
Separation:
Position the magnets within the container so that they are far from the walls, reducing the risk of the magnetic field leaking out.
3.Follow Packaging Guidelines
Dangerous Goods Classification:
Magnets that do not meet the above magnetic field criteria are considered “dangerous goods” by the International Air Transport Association (IATA). For these, you must follow IATA Dangerous Goods Regulations (DGR).
Packaging Requirements:
According to IATA DGR, the packaging must be sturdy and designed to prevent the magnets from shifting, which could change the magnetic field distribution. Use materials that can withstand rough handling and prevent any movement of the magnets.
Labeling:
Clearly label the package with the appropriate “Magnetized Material” label if the package contains magnets that meet the defined criteria but are not classified as dangerous goods.
4.Consult Your Carrier
Different airlines and shipping carriers may have additional requirements or recommendations for transporting magnets by air.
Contact the carrier in advance to understand their specific policies and ensure that all documentation and packaging meet their standards. This step is especially important if you are shipping internationally, as regulations can vary by country.
5. Documentation
Prepare all necessary documentation, including a declaration of dangerous goods if applicable, detailed packing instructions, and proof of magnetic field measurements.
Ensure all documentation complies with both IATA regulations and the specific requirements of your chosen carrier.
6. Compliance and Training
Ensure all personnel involved in packaging and shipping magnets are trained in handling and preparing magnetic materials for air shipment.
Stay updated on changes in regulations and guidelines from the FAA, IATA, and other relevant authorities to maintain compliance and safety.
By following these detailed steps and guidelines, you can safely ship magnets by air while adhering to all relevant safety regulations and minimizing the risk of electromagnetic interference with aircraft systems.
