Product classification
HS code for Maize bran: 2302.10
Bran, sharps and other residues, of maize (corn), whether or not in the form of pellets, derived from the sifting, milling or other workings thereof.
Classification of maize bran under HS 2302.10
Maize bran is classified under HS code 2302.10, which covers residues from the sifting, milling, or other workings of maize. This classification is part of Chapter 23, which encompasses residues and waste from the food industries and prepared animal fodder. When maize is processed to produce cornmeal, grits, or flour, the outer hull and parts of the germ are separated; these by-products are collectively known as bran or sharps. The classification under 2302.10 is contingent upon the product meeting specific technical criteria regarding its starch and ash content, as defined in the Chapter 23 notes. If the residue contains too high a percentage of starch, it may be reclassified as cereal groats or meal under heading 1103. However, for standard industrial maize bran used in the animal feed industry, 2302.10 is the globally recognized code. This heading also includes pellets made from these residues. It is important to distinguish these milling residues from residues of starch manufacture (such as corn gluten feed), which are classified under heading 2303. The distinction lies in the process: 2302 is for mechanical milling residues, while 2303 is for residues resulting from the chemical or water-based extraction of starch. Proper classification is essential for compliance with agricultural import quotas and feed safety regulations.

Codes often confused with 2302.10
Common mistake. Maize bran is frequently confused with maize flour (1102.20) or maize groats (1103.13). The distinction is based on the starch content and the passage through a standard sieve. Another common misclassification is 2303.10, which covers residues of starch manufacture (corn gluten). While both are used for animal feed, 2303.10 products are the result of a wet-milling process, whereas 2302.10 products are the result of dry-milling or sifting. Using the wrong code can lead to significant differences in duty rates and inspection requirements.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
