Magnets are small but surprisingly demanding to pack. They are brittle, they are magnetic, and many are prone to corrosion. Good packaging solves all three problems at once — get it right and the magnets arrive perfect; get it wrong and they arrive as scrap.
Cushion and separate
Two magnets knocking together chip and crack. Each piece needs cushioning — foam, corrugated dividers or molded inserts — and must be separated from other magnets. Steel tools nearby are just as dangerous: a loose screwdriver can snap onto a packed magnet and damage it.
Keep them dry
Nickel-plated NdFeB magnets corrode when moisture gets in. Packaging should keep them dry: sealed bags, and desiccant for long storage or sea freight. For shipments crossing oceans, humidity can be brutal — plan packaging for the worst leg of the journey, not the best. A rusted magnet is a rejected magnet, no matter how strong it was at the factory.
Mind the stray field
Strong magnets erase magnetic cards and upset electronics nearby. Keep packed magnets away from phones, credit cards, watches and medical devices during storage and transit.
Shipping rules
Strong magnets face strict air freight rules: they must be packed so the field at the package surface stays within limits, usually with steel shielding or pole-to-pole stacking. Land and sea shipping are more forgiving, but the same protective packing applies.
Check on arrival
Inspect packaging before signing for goods — bent boxes and wet cartons are early warning signs. If cartons arrive damaged, photograph everything before unpacking; evidence helps with claims. Handle unpacking carefully: separate magnets one by one, and keep steel tools away from the box.
