Machinery, for use in the milling industry or for the working of cereals or dried leguminous vegetables, other than farm-type machinery.
Classification of flour mill under HS 8437.80
Flour mills are classified under HS code 8437.80, which covers machinery for the milling industry or for the working of cereals or dried leguminous vegetables. This code is situated in Chapter 84, which covers nuclear reactors, boilers, machinery, and mechanical appliances. Heading 8437 specifically addresses machines for cleaning, sorting, or grading seed, grain, or dried leguminous vegetables, as well as machinery used in the milling industry. Subheading 8437.80 is the residual category for milling machinery that is not specifically for cleaning or sorting. This classification applies to industrial-scale equipment used to grind grain into flour. It is important to distinguish these from farm-type machinery or domestic appliances. The classification is driven by the industrial capacity and the specific mechanical process of cereal reduction, ensuring that specialized food processing equipment is correctly identified for tariff purposes.

Codes often confused with 8437.80
Common mistake. Flour mills are frequently misclassified under HS code 8436.80, which covers other agricultural or horticultural machinery; however, 8437 is more specific to the milling industry. Another common error is using HS code 8509.40, which is for domestic food grinders and mixers. Industrial flour mills must be classified in Chapter 84. Additionally, machinery for the preparation of fruits or vegetables (as opposed to cereals) falls under HS code 8438.60.

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).
