Machines, for cleaning, sorting or grading seed, grain or dried leguminous vegetables.
Classification of seed cleaner under HS 8437.10
A seed cleaner is classified under HS code 8437.10. This heading covers machines for cleaning, sorting, or grading seed, grain, or dried leguminous vegetables. It is situated within Chapter 84, which encompasses nuclear reactors, boilers, machinery, and mechanical appliances. The classification is based on the machine's specific function in the post-harvest processing of agricultural products. Seed cleaners typically utilize various mechanical methods, such as vibrating screens, air aspiration, and gravity separation, to remove impurities, dust, and chaff from seeds. According to GRI 1, the specific description in heading 8437 for machinery used in the milling industry or for the working of cereals takes precedence. This code applies to both industrial-scale cleaning plants and smaller mobile units used on farms to prepare seeds for planting or sale.

Codes often confused with 8437.10
Common mistake. Seed cleaners are sometimes misclassified under 8433.60, which covers machines for cleaning or grading eggs, fruit, or other agricultural produce. However, 8437.10 is specific to seeds, grains, and legumes. Another common error is classifying them under 8474.10 if they are perceived as general sorting or screening machines; however, 8474 is reserved for mineral substances like earth, stone, or ores. Additionally, if the machine is a simple centrifugal separator, it might be confused with 8421, but the specialized agricultural purpose of 8437.10 is the primary classification factor.

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).
