Product classification
HS code for Grain sorter: 8437.10
Machines, for cleaning, sorting or grading seed, grain or dried leguminous vegetables.
Classification of grain sorter under HS 8437.10
Grain sorters are classified under HS code 8437.10, which covers machines for cleaning, sorting, or grading seed, grain, or dried leguminous vegetables. This classification is based on the machine's specific application within the milling industry or for the preparation of agricultural produce. Heading 8437 is a specialized category for machinery used in the processing of cereals or dried vegetables, distinguishing it from general-purpose sorting machinery. Grain sorters utilize various technologies, including mechanical sieves, gravity separation, and advanced optical sensors (color sorters), to remove impurities, damaged grains, or foreign matter from a bulk stream. Under GRI 1, the specific mention of "sorting... grain" in the heading text for 8437 makes this the primary classification. These machines are typically used in grain elevators, flour mills, and seed processing plants. The classification remains 8437.10 regardless of whether the sorting mechanism is mechanical, electronic, or pneumatic, as long as the intended material being processed is grain or seed.

Codes often confused with 8437.10
Common mistake. Grain sorters are sometimes misclassified under HS code 8433.60, which covers machines for cleaning or grading eggs, fruit, or other agricultural produce. However, heading 8437 is the more specific code for grains and leguminous vegetables. Another common error is using HS code 8474.10, which is for sorting and screening mineral substances; this code is inappropriate for biological agricultural products like grain.

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).
