Product classification
HS code for Batch weigher: 8423.30
Weighing machines, constant weight scales and scales for discharging a predetermined weight of material into a bag or container, including hopper scales.
Classification of batch weigher under HS 8423.30
A batch weigher is classified under HS code 8423.30 because it is a specialized weighing machine designed for the automatic measurement and discharge of predetermined weights of material. Unlike general-purpose scales that provide a static reading of an object's mass, batch weighers are integrated into industrial workflows to ensure consistent quantities of bulk goods—such as grains, powders, or liquids—are processed or packaged. The classification under 8423.30 specifically covers constant weight scales and scales for discharging a predetermined weight into a bag or container, including hopper scales. This classification is driven by the machine's mechanical function of automation and its role in repetitive industrial weighing tasks. The Harmonized System places these in Chapter 84 because they are considered mechanical appliances with individual functions, where the weighing mechanism is the primary feature of the apparatus.

Codes often confused with 8423.30
Common mistake. Batch weighers are often confused with HS code 8423.81 or 8423.82, which cover other weighing machinery based on weight capacity (under 30 kg or between 30 kg and 5,000 kg). However, if the machine is designed for automatic batching or discharging a predetermined weight, 8423.30 takes precedence regardless of the total capacity. Another misclassification occurs with HS code 8422.30, which covers machinery for filling and closing containers; if the primary function is the precise weighing of the batch rather than the mechanical act of sealing the container, 8423.30 is the correct heading.
Top exporters and importers of HS 842330 (the code used for batch weigher), 2025
In 2025, the largest exporter of HS 842330 (the code used for batch weigher) in UN Comtrade data was China, with 20% of world exports; the largest importer in UN Comtrade data was the United States, with 20% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.
Figures cover everything classified under HS 842330, not only batch weigher.

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 batch weigher
What is the HS code for Batch weigher?
The HS code for Batch weigher is 842330 (Weighing machines; constant weight scales and scales for discharging a predetermined weight of material into a bag or container, including hopper scales). The correct HS code for an industrial batch weigher or constant weight scale is 8423.30.
How do I classify Batch weigher for customs?
Batch weigher is classified under HS code 842330 — Weighing machines; constant weight scales and scales for discharging a predetermined weight of material into a bag or container, including hopper scales. This is a 6-digit subheading level code.
Does this code include the electronic sensors?
While the complete machine is 8423.30, individual load cells or weighing sensors imported separately are typically classified under 8423.90 as parts of weighing machinery.
Which countries are the top exporters of batch weigher (HS 842330)?
In 2025, the top exporters of HS 842330 (the code used for batch weigher) in UN Comtrade data were China ($159M, 20% of world exports), Japan ($145M) and Germany ($121M). World exports came to about $775M, 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.
Which countries are the top importers of batch weigher (HS 842330)?
In 2025, the top importers of HS 842330 (the code used for batch weigher) in UN Comtrade data were the United States ($132M, 20% of world imports), the Netherlands ($40M) and Germany ($37M). World imports came to about $675M, 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.
