Short answer. Vietnamese mangosteen is in season from late April to July, with the main crop in July. It comes from Cho Lach (now Vinh Long), Ke Sach (now Can Tho) and Lai Thieu (now Ho Chi Minh City). Fruit is sized in five codes, from 30 g to over 125 g, and graded in two classes under Codex CXS 204-1997.
