Southern Thailand's 2026 mangosteen output is reported at 139,936 tonnes, up 75% on last year, with early-season grade A farm-gate prices around 40-50 baht/kg and grade-down fruit at 10-15 baht/kg. Traders are already buying whole orchards in advance, with small orchards selling for 4,000 baht and up. Yala prices run higher (grade A about 80 baht/kg). If you buy, sell, pack or supply mangosteen, expect a heavy crop and price swings through the season; prices for mid and late season are not yet known. Size and pruning affect export grading, so orchard management matters for the premium.
