Import Tips
• Provide lab analysis confirming high starch content if challenged, as some Dioscorea varieties border on medicinal uses
• Comply with USDA APHIS import permits for tubers from Asia to prevent pest introduction
• Document IQF process to distinguish from block-frozen, affecting storage and duty uniformity
