We've just discussed with our forwarder about new magnetic and roller. We conclude that before sending out new ones, we need to return the old magnetic and roller to Wuxi Double Elephant firstly and we will specify description of goods as "Defected Cargo: return to Wuxi Double Elephant". It will be easier for us to declare to TH customs.
Pls check with Wuxi double Elepahant whether this invoice is ok or not. Any idea, pls advise.
