The debris, which was picked up on the Mozambique coastline, could provide fresh clues into the mystery of the Malaysia Airlines flight, which disappeared two years ago.
"We officially gave the piece to the Malaysian experts this morning," Joao de Abreu, president of Mozambique's Civil Aviation Institute, told AFP.
"If it is revealed that it belongs to MH370, then these experts will come back to Mozambique to launch more extensive searches."
The Malaysian team will leave Maputo on Tuesday and the piece will be taken on to Australia for analysis.
