Classification of oat grain under HS 1004.90
Oat grain intended for consumption or animal feed is classified under HS code 1004.90. Chapter 10 of the Harmonized System is dedicated to cereals, and heading 1004 specifically covers oats. The subheading 1004.90 is a residual category for "other" oats, meaning oats that are not intended for use as seed for sowing. To be classified here, the oats must be in their grain form, typically with the husk (hull) still attached or simply cleaned. If the oats have undergone more significant processing, such as hulling, rolling, or flaking, they move out of Chapter 10 and into Chapter 11. The distinction between 1004.10 (seed) and 1004.90 (other) is usually supported by phytosanitary certificates or documentation indicating the grain's intended use. This code is used for bulk shipments of raw oats used in the production of livestock feed or as the raw material for the milling industry. The grain must not be worked beyond basic cleaning or drying to remain in this heading.

Codes often confused with 1004.90
Common mistake. The most common misclassification is using 1004.10, which is strictly for seed oats intended for sowing. Importers must provide proof of seed quality and intent to use 1004.10. Another error is confusing raw grain with processed oats under 1104.12 (rolled/flaked) or 1104.22 (hulled/pearled). Once the husk is removed (hulled), the product is no longer classified in Chapter 10. Finally, oat residues or bran should be classified under 2302.40 rather than 1004.90.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. 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).
