HS code for Conveyor scale: 8423.20
Weighing machines, scales for continuous weighing of goods on conveyors.
Classification of conveyor scale under HS 8423.20
A conveyor scale is classified under HS code 842320. This code falls under heading 8423, which covers weighing machinery (excluding balances of a sensitivity of 5 cg or better), including weight-operated counting or checking machines. Subheading 842320 is specifically reserved for scales for the continuous weighing of goods on conveyors. These devices are distinct from static scales because they are designed to measure the mass of material as it moves along a belt, often integrating load cells and speed sensors to calculate the total flow rate. The classification is determined by the functional nature of the machine as a weighing instrument integrated into a material handling system. Even if the scale is part of a larger conveyor assembly, the weighing mechanism itself is the defining feature for this specific HS code.

Codes often confused with 8423.20
Common mistake. Conveyor scales are often misclassified under 842330, which is for constant weight scales and scales for discharging a predetermined weight into a bag or container (hopper scales). They may also be confused with 842381 or 842382, which cover general weighing machinery. Additionally, some importers mistakenly use 903180, which covers other measuring or checking instruments, but 8423 is more specific for weighing functions.
Top exporters and importers of HS 842320 (the code used for conveyor scale), 2025
In 2025, the largest exporter of HS 842320 (the code used for conveyor scale) in UN Comtrade data was China, with 16% of world exports; the largest importer in UN Comtrade data was the United States, with 15% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).
