Product classification
HS code for Mower blades: 8433.90
Harvesting machinery, parts, including parts of threshing machinery, straw or fodder balers and grass or hay mowers.
Classification of mower blades under HS 8433.90
Mower blades are classified under HS code 8433.90. This classification falls within Chapter 84, specifically heading 8433, which covers harvesting or threshing machinery, including grass or hay mowers. Subheading 8433.90 is designated for \"parts\" of the machinery described in the preceding subheadings. While blades are cutting tools, they are classified here because they are identifiable as parts solely or principally used with the mowing machines of heading 8433. According to Section XVI Note 2(b), parts that are suitable for use solely or principally with a particular kind of machine are to be classified with those machines. Since these blades are specifically engineered for the rotational or reciprocating motion of agricultural or lawn mowers, they are excluded from general tool categories and placed within the machinery parts category. This applies to blades for both tractor-mounted agricultural mowers and domestic lawn mowers, provided they are presented as parts of the machine rather than general-purpose knives.

Codes often confused with 8433.90
Common mistake. A frequent error is classifying mower blades under HS code 8208.40, which covers knives and cutting blades for agricultural, horticultural, or forestry machines. While 8208.40 is a valid code for many cutting attachments, the specific parts provision in 8433.90 often takes precedence for blades that are integral components of the mower's mechanical assembly. Additionally, some may attempt to use 7326.90 for general steel articles, but the specific functional classification as a machine part under 8433.90 is legally required.

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).
