Packing and Shipping:

Packaging and Shipping of Bonded Neodymium Magnet

Bonded neodymium magnets are prone to cracking and chipping, so it is important to take proper care while packaging and shipping them. We recommend the following packaging and shipping protocols:

  • Place the magnet into a plastic bag to shield it from any external damage.
  • Surround the plastic bag with foam to provide additional cushioning.
  • Place the bagged magnet into a box of appropriate size.
  • Fill any remaining space in the box with packing peanuts or other cushioning material.
  • Securely close the box with packing tape.
  • Label the box with the correct shipping address and handling instructions.
  • Ship the box via a reliable courier.
