Starch Manufacture Residues — Corn Gluten Feed, Corn Gluten Meal & Similar By-Products

Corn gluten feed and corn gluten meal — the two most commercially significant products under this heading — are high-volume by-products of wet-milling operations and serve as widely used protein and energy supplements in dairy, beef, and poultry rations. The US schedule distinguishes corn gluten feed (2303100010), corn gluten meal (2303100020), and other starch manufacture residues (2303100040), with corn gluten meal commanding a premium due to its higher protein concentration. Canada and France are the leading import suppliers, though domestic US wet-milling capacity makes this heading primarily an export-oriented category for the US.
