Both pearled and hulled barley fall within this heading, as both are forms of worked cereal grains. Hulled barley has only the inedible outer husk removed, while pearled barley has been further polished to remove the bran layer. The distinction matters commercially—hulled barley is considered a whole grain while pearled is not—but both remain within the same trade heading.

Kibbled grains intended for human consumption must be clearly distinguished from similarly processed feed-grade products through labeling, accompanying documentation, and the declared end use. FDA will assess admissibility based on the product's intended use; if there is ambiguity, the shipment may be detained for further review. Accurate commercial invoices and product specifications help avoid misclassification.
