Product classification
HS code for Valve parts: 8481.90
Taps, cocks, valves and similar appliances, parts thereof.
Classification of valve parts under HS 8481.90
Valve parts are classified under HS code 8481.90. This classification follows Note 2 to Section XVI of the Harmonized System, which states that parts of machines or appliances are to be classified with those machines if they are suitable for use solely or principally with a particular kind of machine. Heading 8481 covers taps, cocks, valves, and similar appliances for pipes, boiler shells, tanks, vats, or the like, including pressure-reducing valves and thermostatically controlled valves. Subheading 8481.90 is the residual category for components that are identifiable as being intended for the assembly or repair of these appliances. To qualify for this code, the part must not be more specifically described in another heading (such as a general-purpose screw or a gasket of multiple materials). The classification depends on the part's dedicated function within the valve assembly, ensuring that the mechanical integrity and flow-control capabilities of the primary unit are maintained.

Codes often confused with 8481.90
Common mistake. Valve parts are frequently misclassified under HS code 7307, which covers tube or pipe fittings of iron or steel. While a valve body may look like a fitting, its role as a housing for a moving mechanism dictates classification in 8481. Additionally, gaskets and similar joints are often incorrectly placed here but should be classified under 8484 or according to their constituent material (e.g., Chapter 40 for rubber) unless they are integral, non-standard components of the valve.

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).
