Product classification
HS code for Pressure sensor fittings: 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 pressure sensor fittings under HS 9026.90
Pressure sensor fittings are classified under HS code 902690, which is the designated category for parts and accessories of instruments and apparatus for measuring or checking the variables of liquids or gases. To fall under this code, the fittings must be identifiable as being solely or principally for use with the instruments of heading 9026. These components are essential for the installation, protection, or operation of pressure sensors but do not perform the measurement themselves. The classification follows Note 2 to Chapter 90, which dictates that parts and accessories that are suitable for use solely or principally with a particular kind of machine or instrument are to be classified with those machines or instruments. This includes specialized adapters, housings, and mounting hardware that are specifically engineered for pressure sensing systems. Proper classification requires that the fitting is not a general-purpose part that could be used in a wide variety of unrelated applications.

Codes often confused with 9026.90
Common mistake. The most common misclassification for sensor fittings is under general hardware headings such as 7307 (tube or pipe fittings of iron or steel) or 3917 (plastic fittings). If a fitting is a standard nut, bolt, or generic pipe connector, it must be classified by its material (e.g., 7318 for steel screws). Only fittings that are specialized and dedicated to the function of the pressure instrument should be classified under 902690. Another error is classifying them under 903290, which is for parts of automatic regulators.
Top exporters and importers of HS 902690 (the code used for pressure sensor fittings), 2025
In 2025, the largest exporter of HS 902690 (the code used for pressure sensor fittings) 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 pressure sensor fittings.

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 pressure sensor fittings
What is the HS code for Pressure sensor fittings?
The HS code for Pressure sensor fittings 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 and accessories of pressure measuring instruments is 902690.
How do I classify Pressure sensor fittings for customs?
Pressure sensor fittings 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.
Can a standard steel pipe fitting be classified as 902690?
No, standard or general-purpose fittings are classified according to their constituent material (e.g., Chapter 73 for steel) rather than as instrument parts.
Which countries are the top exporters of pressure sensor fittings (HS 902690)?
In 2025, the top exporters of HS 902690 (the code used for pressure sensor fittings) 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 pressure sensor fittings (HS 902690)?
