HS code for Disc harrow: 8432.21
Harrows, disc harrows.
Classification of disc harrow under HS 8432.21
The disc harrow is classified under HS code 8432.21. This classification falls within Chapter 84, which covers nuclear reactors, boilers, machinery, and mechanical appliances. Specifically, heading 8432 includes agricultural, horticultural, or forestry machinery for soil preparation or cultivation. Within this heading, the code 8432.21 is reserved exclusively for disc harrows. These implements are defined by their use of circular steel discs, often with serrated or notched edges, arranged in gangs. The discs rotate as the harrow is pulled across the field, cutting through weeds, breaking up clods of earth, and incorporating crop residue into the soil. The classification is determined by the primary mechanical function of the machine—soil preparation—and its specific design using discs rather than tines or blades. This code applies to both trailed and tractor-mounted versions, provided they function as disc harrows for agricultural use.

Codes often confused with 8432.21
Common mistake. Disc harrows are sometimes misclassified under HS code 8432.10, which is reserved for ploughs, or HS code 8432.29, which covers other harrows, scarifiers, cultivators, weeders, and hoes. While a disc harrow performs a similar function to a plough (tillage), the mechanical structure of the disc gang is the defining feature for 8432.21. Furthermore, if the discs are part of a combined machine that also performs seeding, it might be classified under 8432.31 (Sowers).

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).
