What Drives Walnut Shell Prices in South America?
1. Agricultural Output and Harvest Cycles
Walnut harvesting in South America typically occurs between March and May, depending on the country. Annual yield, weather conditions, and export levels all impact local availability and prices.
2. Export Demand and Industrial Use
South America exports walnut shells primarily to:
-
North America (for blasting media)
