HS code for Pressure reducing valve: 8481.10
Valves, pressure reducing, for pipes, boiler shells, tanks, vats or the like.
Classification of pressure reducing valve under HS 8481.10
HS code 848110 is the specific classification for pressure-reducing valves. These devices are categorized under heading 8481, which encompasses a wide range of taps, cocks, valves, and similar appliances for pipes, boiler shells, tanks, vats, or the like. A pressure-reducing valve is a mechanical device designed to automatically reduce a higher, fluctuating upstream pressure to a lower, constant downstream pressure, regardless of changes in the inlet pressure or flow rate. This function is vital for protecting sensitive equipment in hydraulic and pneumatic systems. The classification is determined by the valve's primary function of pressure reduction. This distinguishes it from other types of valves in the same heading, such as check valves or safety valves. While a safety valve is designed to vent pressure in an emergency, a pressure-reducing valve operates continuously to maintain a specific set point. The classification applies whether the valve is made of iron, steel, brass, or other materials, provided it is used for the specified purpose in piping or container systems. It is also distinct from automatic regulators of heading 9032, which typically involve a more complex control loop often involving electrical components, whereas 848110 valves are generally self-contained mechanical units.

Codes often confused with 8481.10
Common mistake. These valves are frequently confused with safety or relief valves (HS code 848140). The difference is functional: 848110 reduces pressure for operational use, while 848140 releases pressure for safety. They may also be confused with hydraulic/pneumatic regulators under 903281 if they are part of a sophisticated control system.
Top exporters and importers of HS 848110 (the code used for pressure reducing valve), 2025
In 2025, the largest exporter of HS 848110 (the code used for pressure reducing valve) in UN Comtrade data was Germany, with 14% of world exports; the largest importer in UN Comtrade data was the United States, with 11% 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).
