2303.10.00.20 - Corn gluten meal

This HTS category, 2303.10.00.20, specifically covers **corn gluten meal**. This is a high-protein product derived from the corn wet-milling process, primarily used as a source of nitrogen in fertilizers due to its slow-release properties and as an ingredient in animal feed. It is distinct from other by-products of starch manufacture by its higher protein content and specific application profiles.

In contrast to its sibling category, 2303.10.00.10, which covers corn gluten feed, corn gluten meal is differentiated by a significantly higher percentage of protein (typically over 60%) and a lower fiber content. Corn gluten feed, while also a residue from corn starch production, is characterized by lower protein and higher fiber, making it more suitable as a bulk feed ingredient for livestock. This distinction is crucial for accurate classification based on the product's nutritional composition and intended use.

As a leaf node, this classification does not have further subcategories. Therefore, the focus for classification remains on accurately identifying the product as corn gluten meal. Classification relies on the physical characteristics, such as its powdery or granular form, and its protein analysis, confirming its origin from corn starch manufacture and its specific composition that aligns with the definition of corn gluten meal.
