HS Code 1003.10 – Cereals; barley, seed
HS code 1003.10 is the 6-digit subheading for cereals, barley, seed. It is used for malting barley seeds, feed barley seeds, brewing barley seeds, winter barley seeds and spring barley seeds.
What HS 1003.10 covers
This HS code specifically covers barley grain intended for sowing, a fundamental input for agricultural production worldwide. Barley is a highly adaptable cereal, cultivated for various purposes including malting for beer and spirits, animal feed, and human consumption in products like pearl barley. International trade in barley seeds is crucial for farmers seeking specific varieties that offer optimal yields, disease resistance, and suitability for local growing conditions. Major importers are often countries looking to expand their brewing industries, livestock farming, or introduce new barley varieties. Exporters typically include nations with significant barley production and advanced seed breeding programs, such as Canada, France, and Germany. Key considerations in this trade involve strict phytosanitary certificates, genetic purity, and intellectual property rights for specific seed varieties, ensuring the quality and viability of the planting material for successful harvests.

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).
