Why is mixer inspection required before shipment?
1. Blenders are small household appliances. Defects on motors or inner wiring may cause no power, strange noise or electric risks. If these faults are found after goods arrive at destination, return‑repair will cost a large sum of money.
2. We can pick out cosmetic defects such as body scratches or cracked mixing cups ahead of shipment. It helps prevent goods rejection and compensation claims from buyers.
3. Operate real‑machine tests to confirm rotating speed and control buttons work well, so end‑users can use the product without trouble.
4. Verify carton marks and packing condition to meet import customs rules and buyer's receiving requirements, lowering trade disputes.
