Potato flour and meal retain the fiber and protein of the whole potato and are classified under food-preparation headings, whereas potato starch is a refined carbohydrate classified separately. The distinction affects both the applicable tariff line and potential duty rate, so laboratory analysis or supplier specification sheets confirming particle composition are advisable before entry.

Imported potato flour must comply with FDA food labeling regulations, including accurate ingredient identification, net weight, and country-of-origin declarations. If the product is marketed as gluten-free, it must also meet FDA's gluten-free labeling standard. Consulting a licensed customs broker and an FDA-registered importer of record is recommended to ensure full compliance.
