HS Code 8423.30 – Weighing machines; constant weight scales and scales for discharging a predetermined weight of material into a bag or container, including hopper scales
HS code 8423.30 is the 6-digit subheading for weighing machines, constant weight scales and scales for discharging a predetermined weight of material into a bag or container, including hopper scales. It is used for hopper scales, batch weighing systems, constant weight fillers, bagging scales and gravimetric feeders.
What HS 8423.30 covers
This HS code encompasses weighing machines designed for precise batching and dispensing of materials, specifically constant weight scales and those that discharge a predetermined weight into containers or bags, including hopper scales. These machines are fundamental to manufacturing processes requiring accurate ingredient measurement, such as food processing, chemical production, pharmaceuticals, and construction materials. They ensure product consistency, minimize waste, and optimize production efficiency. International trade in these specialized scales is driven by industrial automation needs and quality control requirements across various sectors. Importers include factories, processing plants, and packaging facilities. Exporters are typically countries with strong industrial engineering and automation sectors. Key factors include accuracy, speed of dispensing, adaptability to different material types (powders, granules, liquids), integration with production lines, and compliance with industry-specific regulations.

Codes often confused with 8423.30
Common mistake. This code is distinct from continuous conveyor scales (842320) and general industrial scales (842381, 842382) because its primary function is batching or discharging a *predetermined* weight. It focuses on discrete, controlled dispensing rather than continuous flow or simple static weighing.
Top exporters and importers of HS code 842330, 2025
In 2025, the largest exporter of HS code 842330 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.

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).
