Product classification
HS code for Belt weigher: 8423.20
Weighing machines, scales for continuous weighing of goods on conveyors.
Classification of belt weigher under HS 8423.20
The belt weigher is classified under HS code 8423.20, which is designated for scales for continuous weighing of goods on conveyors. This classification is part of Chapter 84, which encompasses machinery and mechanical appliances. Heading 8423 specifically covers weighing machinery, excluding balances of a sensitivity of 5 cg or better. The determination for 8423.20 is based on the mechanical nature of the device and its specific application in a continuous flow environment. Unlike static scales, a belt weigher measures the mass of material as it moves across a conveyor belt, integrating the weight and the belt speed to provide a flow rate and totalized mass. This specific functionality distinguishes it from other types of weighing equipment and necessitates its placement in the subheading for continuous weighing systems.

Codes often confused with 8423.20
Common mistake. Belt weighers are often confused with HS code 8423.30, which covers constant weight scales and scales for discharging a predetermined weight of material into a bag or container (check-weighers). The key difference is that 8423.20 is for continuous measurement of an uninterrupted flow, while 8423.30 is for batching or checking specific units. Another common error is using HS code 8423.81 or 8423.82, which are for general-purpose scales based on weight capacity. If the scale is integrated into a conveyor for continuous use, 8423.20 takes precedence. Additionally, if the import consists only of the electronic load cell without the mechanical frame, it might be classified under 8423.90 (parts) or 9031.80 (measuring instruments).
Top exporters and importers of HS 842320 (the code used for belt weigher), 2025
In 2025, the largest exporter of HS 842320 (the code used for belt weigher) 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).

Questions about belt weigher
What is the HS code for Belt weigher?
The HS code for Belt weigher is 842320 (Weighing machines; scales for continuous weighing of goods on conveyors). The correct HS code for a belt weigher used for continuous weighing on a conveyor is 8423.20.
How do I classify Belt weigher for customs?
Belt weigher is classified under HS code 842320 — Weighing machines; scales for continuous weighing of goods on conveyors. This is a 6-digit subheading level code.
Does this code include the conveyor belt itself?
Generally, no. If the conveyor is imported as a complete material handling system, it might be classified under 8428. However, the weighing mechanism itself is classified under 8423.20. If the belt is imported separately, it falls under 4010.
Which countries are the top exporters of belt weigher (HS 842320)?
In 2025, the top exporters of HS 842320 (the code used for belt weigher) in UN Comtrade data were China ($30M, 16% of world exports), Japan ($28M) and Germany ($27M). World exports came to about $182M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
