Corn bran and sharps under SITC 08124 are specifically residues from sifting or milling operations. Distillers dried grains (DDGS) originate from fermentation, not milling, and fall under a separate SITC heading. Corn gluten feed, a wet-milling co-product, may overlap depending on fiber and protein content, so buyers should confirm the production process with the supplier to ensure correct classification.

Dry-milled corn bran typically trades at moisture levels below 12% and crude protein in the 8–10% range, while wet-milling residues can carry higher moisture. Contracts generally specify maximum moisture, minimum crude fiber, and minimum crude protein; deviations can trigger price adjustments or rejection at destination.
