HS code for Density meter: 9026.80

Instruments and apparatus, for measuring or checking variables of liquids or gases (excluding pressure or the flow and level of liquids and those of heading no. 9014, 9015, 9028 and 9032).

Classification of density meter under HS 9026.80

Density meters, specifically those used for measuring the physical properties of liquids or gases, are classified under HS code 9026.80. This heading is reserved for instruments and apparatus for measuring or checking variables of liquids or gases, such as flow, level, or pressure (though pressure has its own subheadings). A density meter in this context measures the mass per unit volume of a fluid, often using oscillating U-tube technology, ultrasonic sensors, or Coriolis effects. These instruments are typically integrated into industrial pipelines or used in laboratory settings to monitor the concentration or purity of a substance. The classification is determined by the device's function as a process control or measurement tool for fluid dynamics, distinguishing it from instruments that perform complex chemical analysis.

Codes often confused with 9026.80

Common mistake. The most frequent misclassification occurs with HS code 9025.11 or 9025.80, which covers hydrometers. While a hydrometer measures density, it is a specific type of floating instrument. Electronic or digital density meters belong in 9026.80. Another common error is using 9027.89 (optical densitometers). As noted in other guides, 9027 is for light-based analysis, while 9026 is for fluid variables.

Top exporters and importers of HS 902680 (the code used for density meter), 2025

In 2025, the largest exporter of HS 902680 (the code used for density meter) in UN Comtrade data was Germany, with 21% of world exports; the largest importer in UN Comtrade data was Germany, 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).
