The Science of Safety

Airlines and regulatory bodies restrict magnets for good reasons. The regulations stem from basic physics and aviation safety principles.
 
Understanding the “why” helps you make smart decisions about your items. It moves you beyond simple yes/no answers to real understanding of the risks.
 
Two main concerns drive all regulations for transporting magnets by air. Both center on the invisible magnetic field that comes from the magnet.
 
Aircraft Navigation Interference
 
The main safety concern is strong magnetic fields interfering with aircraft navigation systems.
 
Regulations protect the magnetic standby compass. This crucial analog backup equipment sits in the cockpit. Modern aircraft use GPS and inertial reference systems for navigation. But these electronic systems can fail.
 
When that happens, flight crews rely on basic analog instruments to find their heading. A powerful, unshielded magnet in cargo or carry-on bags could make the compass needle move. This gives false readings.
 
The Federal Aviation Administration (FAA) creates safety protocols against all potential hazards. Protecting these backup systems is essential for flight safety under all circumstances.
 
Cargo Disruption Risks
 
Beyond the cockpit, there’s another concern. Magnets can affect other items in the cargo hold or nearby passenger luggage.
 
Powerful magnets cause significant disruption. An unshielded neodymium magnet can create a field strong enough to damage sensitive electronics in an adjacent suitcase.
 
The risks to other goods are serious and varied:
 
  • Erasing data from magnetic storage like older hard drives or credit card strips
  • Damaging sensitive electronics, including laptops, cameras, or medical devices
  • Interfering with automated baggage systems at airports that use magnetic sensors
  • Physically attracting metallic items, potentially damaging both the magnet and other objects during transit

Official TSA & FAA Rules

The Transportation Security Administration (TSA), Federal Aviation Administration (FAA), and International Air Transport Association (IATA) have created specific, coordinated rules to ensure safety.
 
This section gives you the hard facts. It cuts through myths and forum stories to deliver precise regulations for air transport of magnets. Following these rules is mandatory for personal travel and commercial shipping.
 
These regulations aren’t based on size, weight, or material alone. The most important factor is magnetic field strength at a specific distance.
 
The Key Strength Metric
 
The deciding factor is the measurable strength of the external magnetic field.
 
According to IATA and FAA regulations, a magnet isn’t restricted as a “dangerous good” if its magnetic field doesn’t cause compass deflection of more than 2 degrees at 7 feet (2.1 meters) from any point on the package exterior.
 
This is the basic test for personal travel. If your packed magnet is weaker than this threshold, it’s generally safe for air transport without special declaration.
 
Stronger magnets shipped as declared cargo use different classification. These are labeled “Magnetized Material” and must have magnetic field strength less than 0.00525 gauss at 15 feet (4.6 meters).
 
These specific measurements determine compliance for air carriers. The IATA Dangerous Goods Regulations (DGR) provide the comprehensive framework used by over 290 airlines worldwide.
 
Carry-On vs. Checked
 
For average travelers, choosing between carry-on and checked luggage depends on magnet strength.
 
Very weak magnets work in either option. These include refrigerator souvenirs, small toys, or consumer electronics with embedded magnets. They pose no aircraft risk.
 
Stronger magnets need checked luggage. This includes hobbyist magnets or certain tools. Placing these in cargo holds increases distance from cockpit navigation equipment. This minimizes interference potential.
 
Here’s a clear comparison:
Feature
Carry-On Luggage
Checked Luggage
Best For
Weak magnets, consumer electronics (MagSafe), small toys.
Stronger hobbyist magnets, tools, properly shielded magnets.

Farther away from the cockpit, reducing interference risk.
Recommendation
Permitted for weak magnets.
Recommended for anything with noticeable strength.
A Simple Rule of Thumb
 
For travelers without a gaussmeter, a simple test helps assess your magnet.
 
Common decorative magnets that stick to refrigerators are weak magnets. They’re perfectly safe for air travel in carry-on or checked bags.
 
Powerful rare-earth magnets that need significant force to remove from steel surfaces require attention. If one can pinch your fingers, pay close attention. This type needs proper shielding and should go in checked luggage.

How to Pack Magnets

Magnet Packaging
Properly packing a magnet is the most critical step for compliance and safety. Packing means shielding—containing the magnetic field so its external strength falls below regulated limits.
 
This practical process prevents airport security issues. We advise all clients to follow these steps for any magnet with significant strength.
 
This process uses two principles: redirecting the magnetic field and increasing distance from the magnet to package exterior.
 
Step 1: Assess Strength
 
Before packing, understand what type of magnet you have. Is it a common, weak ferrite magnet, or a powerful rare-earth magnet?
 
The most common high-strength magnets are neodymium. If you purchased powerful neodymium magnets, they always require careful handling and shielding for air travel. The grade (like N42, N52) indicates strength. Higher numbers mean more powerful magnets.
 
If unsure, err on the side of caution. Assume it’s strong enough to require shielding.
 
Step 2: Shield Your Magnets
 
Shielding is the core of safe magnet packing. It doesn’t block the magnetic field but redirects it.
 
The most effective method uses a “keeper.” A keeper is steel or iron placed across magnet poles (or between two magnets with opposite poles facing each other). This creates a closed loop, redirecting magnetic field lines through steel instead of surrounding space.
 
For multiple magnets, arrange them in a stack with alternating North and South poles facing each other. This helps cancel the external field.
 
Once the magnet assembly is “keepered,” boxing begins. This uses distance to dramatically reduce field strength.
 
  1. Wrap the keepered magnet assembly in generous padding like thick bubble wrap or foam
  2. Place the wrapped magnet in a small, sturdy inner box. Fill empty space with more packing material to prevent shifting
  3. Center this inner box inside a larger, strong outer box
  4. Fill space between inner and outer box on all sides with at least 2-3 inches of firm packing material (foam, cardboard inserts, or tightly packed bubble wrap)
     
Distance is your best tool. Magnetic field strength decreases exponentially with distance. By centering the magnet, you ensure its field is negligible by the time it reaches package exterior.
 
Step 3: Labeling and Declaration
 
For personal travel with properly shielded magnets in checked luggage, no special declaration or label is typically required. The package is now considered non-hazardous.
 
However, if TSA agents or airline staff question your bag contents, be prepared to explain what it is and how it’s been packed safely.
 
For commercial shipments, rules are stricter. If packages contain magnets strong enough to be classified as “Magnetized Material,” they must be formally declared and labeled. This critical distinction is covered in the next section.

Shipping Magnets for Business

Transporting magnets for business, e-commerce, or industrial purposes involves more formal processes than packing them in personal suitcases. The stakes are higher. Compliance is non-negotiable.
 
This section provides critical, often hard-to-find information businesses need. We’ll cover differences between shipping methods, documentation requirements, and when air freight isn’t viable.
 
As a supplier, we have extensive first-hand experience navigating these logistics. Rejected shipments cause costly delays and damage client relationships. Compliance is a top priority.
 
Air Cargo vs. Air Express
 
For businesses, two primary air shipping options are Air Express (like FedEx, DHL, UPS) and traditional Air Cargo.
 
Air Express carriers are preferred for smaller, time-sensitive shipments. They offer door-to-door service and simplified customs processes. However, they may have specific, often stricter rules for accepting magnetized materials to streamline automated sorting operations. Always check your chosen carrier’s specific policy. The UPS Guide for Shipping Special Items provides a starting point.
 
Air Cargo handles larger, bulkier, or palletized shipments. This method offers more flexibility for declared dangerous goods but requires formal documentation and coordination with freight forwarders.
Magnetized Material Declaration
 
When a package’s magnetic field exceeds passenger limits but stays within cargo limits (less than 0.00525 gauss at 15 feet), it must be shipped as fully regulated cargo.
 
This requires completing a Shipper’s Declaration for Dangerous Goods. The package must also have the official IATA “Magnetized Material” handling label. This distinctive blue and white label (IATA Figure 7.3.A) features a U-shaped magnet and compass. It immediately tells airline personnel how to handle and position the package in aircraft.
 
The shipper is solely responsible for correct packing, marking, and documentation. Failure to declare can result in severe penalties.
Sea or Ground Freight
 
For some magnets, air travel simply isn’t an option.
 
Extremely large and powerful magnetic assemblies produce magnetic fields that can’t be shielded enough to meet air travel regulations. These include equipment for industrial separation, medical imaging (MRI components), or scientific research.
 
In these cases, ground or sea freight are the only viable alternatives. While slower, these methods have far fewer magnetic field restrictions and are significantly more cost-effective for heavy, bulk shipments. When we handle large-scale orders of industrial magnets, we often coordinate ground or sea freight for compliant and economical delivery.
Importance of Your Supplier
 
Navigating IATA and FAA regulations can be daunting for any business. The consequences of mistakes are serious—rejected shipments, fines, or damaged products.
 
This is where supplier expertise becomes invaluable. A knowledgeable supplier does more than sell products. They act as partners, providing essential guidance on packaging, shielding, and documentation requirements.
 
This expertise ensures your shipments are never delayed, rejected, or seized due to non-compliance. If you have questions about shipping your order, our team of experts is here to help. We ensure every shipment we facilitate is fully compliant with all regulations.

Common Magnet Examples

Let’s apply the rules to common magnetic items people frequently travel with or ship. This section provides quick, direct answers for popular products.
 
We’ll give clear verdicts for each item based on typical strength and use cases.
 
Consumer Electronics
 
This category includes Apple’s MagSafe chargers, magnetic phone mounts, tablet cases with magnetic closures, and headphones.
 
These products are everywhere and designed by manufacturers with global travel in mind. The magnets are strong enough to function but have very localized, weak fields that dissipate almost immediately. They’re well below any regulatory threshold. Understanding these small magnets’ physics is key. You can learn more about general magnet science from authoritative sources like the National High Magnetic Field Laboratory.
 
Verdict: Safe. These items are permitted in both carry-on and checked luggage without special precautions.
 
Magnetic Toys and Crafts
 
This includes popular children’s toys like magnetic building tiles (Magna-Tiles), fidget toys, and magnetic art or poetry kits.
 
Magnets in these products are almost always weak ferrite magnets, not powerful rare-earth magnets. Their primary function is simple attraction. Their field strength is negligible, posing no threat to aircraft systems.
 
Verdict: Safe. These are fine to pack in carry-on or checked luggage.
 
Powerful Neodymium Magnets
 
This category requires the most attention. It includes loose neodymium or samarium-cobalt magnets purchased for hobbies, DIY projects, scientific experiments, or industrial prototyping.
 
These are the magnets regulations were written for. A single, small N52 neodymium cube can be surprisingly powerful. While they can be brought on planes, it’s only if packed correctly using shielding and isolation methods described earlier in this guide.
 
Verdict: Use Caution. These are permitted only if packaging effectively shields the magnetic field to meet FAA/IATA limits. We strongly recommend placing them in checked luggage after proper packing.
 
Magnetic Tools and Hardware
 
This broad category ranges from small magnetic parts trays and retrieval tools to large industrial magnetic sweepers or lifting magnets.
 
Permissibility depends entirely on the tool’s size and strength. A small magnetic screwdriver or wristband for holding screws is generally fine. A large magnetic sweeper designed to pick up nails from factory floors would be too powerful for any passenger air travel and must be shipped as freight. When in doubt, check the TSA’s “What Can I Bring?” page for general tool guidance.
 
Verdict: Depends on Strength. Small handheld tools are usually acceptable in checked bags if packed with care. Large industrial magnetic tools must be shipped as declared freight.

Your Final Checklist

By following official guidelines and using proper packing techniques, transporting magnets by air can be straightforward and safe. This final checklist summarizes the most critical points to ensure you’re prepared.
 
Key Takeaways
 
Use this list as a final check before heading to the airport or preparing a shipment.
 
  • Know Your Magnet: Weak magnets in most toys and electronics are fine. Strong rare-earth magnets (neodymium) require special care.
  • Shield and Isolate: For any strong magnet, use steel keepers and double-box methods to contain magnetic fields and increase distance.
  • Check It In: When in doubt about magnet strength, always place properly packed items in checked luggage, not carry-on.
  • Declare for Business: All commercial shipments of strong magnets must be correctly classified, documented, and labeled according to IATA regulations.
  • Ask for Help: If you’re unsure about any step, contact your airline or a magnet expert for guidance before you travel or ship.
