Product classification
HS code for Combine: 8433.51
Combine harvester-threshers.
Classification of combine under HS 8433.51
The HS code 8433.51 specifically covers combine harvester-threshers, which are complex agricultural machines designed to perform multiple harvesting operations in a single pass. These machines combine the functions of reaping, threshing, and winnowing. Classification under this code is governed by the functional nature of the machinery as described in Chapter 84 of the Harmonized System. Unlike simple mowers or separate threshing machines, the "combine" is a unified piece of equipment. The classification remains consistent whether the machine is self-propelled or tractor-drawn, though most modern combines are self-propelled. Under General Interpretative Rule 1, the specific mention of "combine harvester-threshers" in the subheading text takes precedence over more general agricultural machinery codes. The inclusion of specialized headers for different crops (like corn or wheat) does not change the base classification of the machine itself.

Codes often confused with 8433.51
Common mistake. Combines are frequently confused with other harvesting machinery under heading 8433. For instance, 8433.52 covers threshing machinery that is not part of a combine unit. Root or tuber harvesting machines, such as potato harvesters, fall under 8433.53 and should not be classified as combines. Another common error is attempting to classify the self-propelled chassis as a tractor under 8701. However, because the chassis is integrally designed for harvesting, Note 2 to Chapter 87 excludes these machines from being classified as tractors. Forage harvesters that do not perform threshing are also distinct and fall under 8433.59.

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).
