HS Code 9031.10 – Machines; for balancing mechanical parts

HS code 9031.10 is the 6-digit subheading for machines, for balancing mechanical parts. It is used for dynamic balancing machines, static balancing machines, crankshaft balancing machines, turbine rotor balancers and propeller balancing systems.

What HS 9031.10 covers

This category covers specialized machinery designed for balancing mechanical parts, which is a critical process in manufacturing to ensure smooth operation, reduce vibration, and extend the lifespan of rotating components. These machines are indispensable in industries such as automotive, aerospace, power generation, and general machinery manufacturing, where components like crankshafts, impellers, rotors, and driveshafts must operate with minimal imbalance. Importers and exporters are typically manufacturers of rotating machinery or specialized balancing service providers. Key aspects include precision measurement of imbalance, automated or semi-automated correction capabilities, and adaptability to various part sizes and weights. The trade in these machines reflects the global demand for high-quality, reliable mechanical systems across diverse industrial applications, contributing significantly to product performance and safety.

Codes often confused with 9031.10

Common mistake. Can be confused with general testing machines under 903180 if the specific function of 'balancing' is not clearly identified. Also, simpler automotive wheel balancers for garages might sometimes be misclassified, but this code focuses on industrial-grade machines.

Top exporters and importers of HS code 903110, 2025

In 2025, the largest exporter of HS code 903110 in UN Comtrade data was Italy, with 21% of world exports; the largest importer in UN Comtrade data was China, with 12% 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).
