Wholesale Sweet Potato Suppliers

China produces approximately 55–60 million tonnes of sweet potatoes annually but primarily for domestic consumption. The United States is the world's leading exporter of fresh sweet potatoes by value, dominated by North Carolina (which produces ~60% of US output), exporting premium orange-flesh varieties to Europe, Canada, and the Middle East. Egypt is a growing exporter of sweet potatoes to European and Gulf markets. Peru exports to European specialty markets. Mozambique and other sub-Saharan African countries produce for regional trade. The global sweet potato market is growing driven by health food trends (superfood positioning) and demand for sweet potato fries in foodservice.

Orange-flesh sweet potatoes (Beauregard, Covington, Jewel, Garnet): dominant in US, European, and Middle Eastern markets; high beta-carotene (provitamin A, ~8–12 mg/100g). White/cream-flesh sweet potatoes: common in Asian and African markets; milder, less sweet flavour; varieties include O'Henry and Bonita. Purple-flesh sweet potatoes (Stokes Purple, Okinawan, Ayamurasaki): premium health food segment; high anthocyanin content used in natural food colouring. Yellow-flesh (Japanese Beniazuma, etc.): common in East Asian cuisine, chestnut-like flavour. Cavendish/Japanese types: drier, starchier texture, prized for baking and roasting in Japanese and Korean cuisine.

UNECE Standard FFV-50 governs sweet potato quality grades in European trade (Extra, Class I, Class II), covering shape, size, and freedom from defects/rots. US Grade Standards (USDA): US No. 1 and US No. 2 for sweet potatoes. Key food safety considerations: sweet potatoes are susceptible to post-harvest rots (Fusarium, Rhizopus soft rot, black rot caused by Ceratocystis fimbriata). Curing (29–32°C, 85–90% RH for 4–7 days) is essential to heal wounds and develop a protective suberin layer. MRL compliance under EU Reg 396/2005. GlobalGAP and USDA organic (NOP) certifications are standard for premium export markets.
