HS Code 8481.30 – Valves; check (nonreturn) valves, for pipes, boiler shells, tanks, vats or the like
HS code 8481.30 is the 6-digit subheading for valves, check (nonreturn) valves, for pipes, boiler shells, tanks, vats or the like. It is used for swing check valves, lift check valves, ball check valves, wafer check valves and dual plate check valves.
What HS 8481.30 covers
Check valves, also known as non-return valves, are fundamental components in fluid systems designed to permit flow in only one direction and automatically prevent backflow. This crucial function protects pumps, prevents contamination, and maintains pressure in various piping systems. In international trade, these valves are widely imported by industries such as water and wastewater treatment, oil and gas, chemical processing, HVAC, and power generation, where preventing reverse flow is critical for operational integrity and safety. Exporters are typically manufacturers specializing in industrial valves, often from regions with strong manufacturing capabilities. Key aspects for trade include the valve's material (e.g., cast iron, stainless steel, PVC), connection type (flanged, threaded, wafer), pressure rating, and the specific application environment. The global market for check valves is driven by infrastructure development, industrial expansion, and the continuous need for reliable fluid control solutions across diverse sectors.

Codes often confused with 8481.30
Common mistake. This code is specifically for check valves, which prevent backflow, differentiating it from other valve types like 848140 (safety valves) or 848180 (general purpose valves) that have different primary functions. It could be confused with 848180 if its non-return function isn't explicitly stated.
Top exporters and importers of HS code 848130, 2025
In 2025, the largest exporter of HS code 848130 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. 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).
