As the "Hometown of Sweet Potatoes in China," Lulong County in Qinhuangdao has developed a complete industrial chain encompassing sweet potato planting, processing, and export, leveraging its local soil and climate conditions. Based on its advantageous production resources, Qinhuangdao Tongyou Potato Industry focuses on potato processing and export, supplying the South Korean market with its sweet potato starch products, becoming a representative enterprise of Hebei agricultural products exported overseas.
Qinhuangdao Tongyou Potato Industry possesses customs import and export registration and export food production enterprise filing qualifications, enabling large-scale production of sweet potato starch. The factory secures stable purchases of fresh sweet potatoes from local and surrounding farmers, processing the raw materials through washing, crushing, filtering, sedimentation, and drying. Relying on a stable local sweet potato supply chain ensures a reliable source of raw materials for export orders.
South Korea's food sector has strict entry requirements for imported edible starches, requiring compliance with relevant regulations from the South Korean Ministry of Food and Drug Safety regarding pesticide residues, microbial indicators, production traceability, and batch testing. To meet the requirements of the South Korean market, Tongyou Potato Industry completes corresponding testing for every batch of sweet potato starch shipped overseas, and fully retains production, testing, and customs clearance data to ensure product traceability. The company has also registered its own trademark in South Korea to adapt to local distribution needs, supplying its sweet potato starch to the South Korean catering and food processing industries.
Besides South Korea, Tongyou Potato Industry's sweet potato starch is also sold to other overseas regions, while simultaneously developing its domestic market and operating its own potato product brand. It is a municipal-level agricultural industrialization enterprise in Qinhuangdao. Its starch, vermicelli, and other products are sold to multiple countries and regions. Tongyou Potato Industry transforms local sweet potato resources into export commodities, promoting the export of local specialty agricultural products.
Going forward, Qinhuangdao Tongyou Potato Industry will continue to organize production according to the regulations and standards of target markets, continuously exporting compliant sweet potato starch products and expanding the overseas market for Lulong sweet potato industry.
