Product classification
HS code for Flow sensor probes: 9026.90
Instruments and apparatus, parts and accessories for those measuring or checking the flow, level, pressure or other variables of liquids or gases (excluding those of heading no. 9014, 9015, 9028 or 9032).
Classification of flow sensor probes under HS 9026.90
Flow sensor probes are classified under HS code 902690. This classification is determined by Note 2 to Chapter 90, which states that parts and accessories for machines, instruments, or apparatus of this chapter are to be classified within the same heading if they are not specifically covered by another heading. Since a probe is a component part of a flow meter (heading 9026) and does not constitute a complete measuring instrument on its own, it falls under the 'parts and accessories' subheading 902690. These probes are the sensing elements that come into contact with the fluid or gas to detect changes in flow, which are then transmitted to a main unit for processing. This code is used for a wide variety of replacement sensors and specialized probe attachments that do not contain the full electronics required to function as a standalone meter.

Codes often confused with 9026.90
Common mistake. Flow sensor probes are often misclassified as complete instruments under 902610 (for liquids) or 902680 (for gases). If the probe cannot display or transmit a standardized measurement signal without an external controller, it must be classified as a part in 902690. Another common error is using 8533 (electrical resistors) or 9033 (parts not elsewhere specified). However, because these are clearly identifiable as parts of 9026 apparatus, 902690 is the legally specific code. Probes for thermostats or pressure switches might also be confused with 903290.
Top exporters and importers of HS 902690 (the code used for flow sensor probes), 2025
In 2025, the largest exporter of HS 902690 (the code used for flow sensor probes) in UN Comtrade data was the United States, with 15% of world exports; the largest importer in UN Comtrade data was the United States, with 13% 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 902690, not only flow sensor probes.

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 flow sensor probes
What is the HS code for Flow sensor probes?
The HS code for Flow sensor probes is 902690 (Instruments and apparatus; parts and accessories for those measuring or checking the flow, level, pressure or other variables of liquids or gases (excluding those of heading no. 9014, 9015, 9028 or 9032)). The HS code for parts of flow meters, including sensor probes, is 902690.
How do I classify Flow sensor probes for customs?
Flow sensor probes is classified under HS code 902690 — Instruments and apparatus; parts and accessories for those measuring or checking the flow, level, pressure or other variables of liquids or gases (excluding those of heading no. 9014, 9015, 9028 or 9032). This is a 6-digit subheading level code.
Is a probe with a built-in digital display still 902690?
No, if the probe has an integrated display and can function as a complete measuring unit, it should be classified as a complete instrument under 902610 or 902680.
Which countries are the top exporters of flow sensor probes (HS 902690)?
In 2025, the top exporters of HS 902690 (the code used for flow sensor probes) in UN Comtrade data were the United States ($821M, 15% of world exports), Germany ($781M) and Japan ($646M). World exports came to about $5.6B, 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 flow sensor probes (HS 902690)?
In 2025, the top importers of HS 902690 (the code used for flow sensor probes) in UN Comtrade data were the United States ($708M, 13% of world imports), China ($675M) and Mexico ($475M). World imports came to about $5.6B, 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.
Is the HS code for Flow sensor probes the same in all countries?
The base HS code 902690 for Flow sensor probes is internationally standardized for the first 6 digits across 200+ countries. Individual countries may add additional digits for national tariff lines and specific classifications.
What is the NCM code for flow sensor probes in Brazil?
Brazil splits HS 902690 into 3 NCM codes, so the right one for flow sensor probes depends on the product's details: 9026.90.10 (Level gauge parts and accessories), 9026.90.20 (Parts and accessories of manometers), 9026.90.90 (Other parts and accessories of fluid instruments).
