HS Code for Batch weigher

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.

Common Misclassification

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.

FAQ

What is the HS code for batch weigher?

The correct HS code for an industrial batch weigher or constant weight scale is 8423.30.

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.
