Customs and FDA documentation should identify the specific legume species (e.g., Cicer arietinum for chickpea, Lens culinaris for lentil) rather than using generic terms like 'pulse flour.' Precise species identification supports accurate tariff classification, facilitates FDA review, and satisfies buyer quality specifications. Vague descriptions can trigger examination holds or reclassification at entry.

While the FDA's major food allergen list does not currently include all legumes, certain legume flours — particularly those derived from soybeans — trigger mandatory allergen labeling under US law. Importers should also be aware that some buyers and retailers require voluntary disclosure for peanut-family legumes. Ensuring that the commercial invoice and product label accurately reflect the legume source helps avoid compliance issues downstream.
