HS code for Check valve: 8481.30
Valves, check (nonreturn) valves, for pipes, boiler shells, tanks, vats or the like.
Classification of check valve under HS 8481.30
Check valves, also known as non-return or one-way valves, are classified under HS code 8481.30. This classification is governed by the functional characteristics of the device within the context of Chapter 84, which covers mechanical appliances. Heading 8481 specifically includes taps, cocks, valves, and similar appliances for pipes, boiler shells, tanks, vats, or the like. Subheading 8481.30 is reserved for valves designed to allow fluid (liquid or gas) to flow in only one direction, automatically closing to prevent backflow. The classification applies regardless of the material of construction—whether brass, stainless steel, plastic, or cast iron—provided the valve is intended for use in piping systems or containers. The mechanical action of the valve, typically involving a flap, ball, or diaphragm, is the primary factor for its inclusion in this specific subheading.

Codes often confused with 8481.30
Common mistake. Check valves are frequently misclassified under 8481.80, which is a 'catch-all' category for other types of valves like gate, globe, or butterfly valves. However, because 8481.30 is a specific provision for non-return valves, it takes precedence over the general category. Another common error is confusing check valves with pressure-reducing valves (8481.10) or valves for oleohydraulic or pneumatic transmissions (8481.20). While a check valve might be used in a hydraulic system, if its primary function is simply to prevent backflow rather than controlling pressure or flow direction via an external actuator, 8481.30 remains the correct code. Additionally, very small valves used in medical devices might be classified in Chapter 90 depending on their specific application.
Top exporters and importers of HS 848130 (the code used for check valve), 2025
In 2025, the largest exporter of HS 848130 (the code used for check valve) in UN Comtrade data was China, with 19% of world exports; the largest importer in UN Comtrade data was the United States, with 14% of world imports.

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).
