Potato starch's exceptionally large granule size and high viscosity at low concentrations make it a preferred functional ingredient in gluten-free formulations, soups, sauces, and certain paper and textile applications where corn starch cannot match its thickening power. European producers — particularly in the Netherlands, Germany, and Denmark — have historically dominated global export supply, reflecting the concentration of potato processing infrastructure in northern Europe. Food-grade imports are subject to FDA oversight, and importers should maintain Foreign Supplier Verification Program documentation. Buyers sourcing from EU suppliers should be aware of any applicable trade-remedy or tariff developments affecting agricultural imports.
