Production and Delivery:
-
Packaging:
- Air Shipment: Requires specialized air-safe packaging for magnetized magnets, significantly increasing gross weight (1.5–2 times the net weight), leading to higher shipping costs.
- Sea Shipment: More cost-effective with lower packing and shipping costs, though delivery times are longer.
- Custom Packaging: Available to meet specific customer requirements for safe transport.
Quality and Compliance:
Manufactured under stringent quality controls, fully compliant with RoHS standards.
Safety Note:
Large neodymium magnets (N30, N35, N52, etc.) are extremely powerful and potentially hazardous. Ensure proper handling experience to manage risks safely.
