HS-6 · Subheading
848130
Valves; check (nonreturn) valves, for pipes, boiler shells, tanks, vats or the like
Heading 8481 — Taps, cocks, valves and similar appliances for pipes, boiler shells, tanks, vats or the like, including pressure-reducing valves and thermostatically controlled valves
Chapter 84: Nuclear reactors, boilers, machinery
Plain-language overview
Use HS-6 848130 when importing or exporting check valves designed for pipes, tanks, or similar applications. For example, a shipment of brass check valves used in a plumbing system falls under this code.
This code specifically covers non-return valves, which prevent backflow in piping systems. In contrast, HS-6 848140 covers pressure-reducing valves, which serve a different function in regulating pressure.
Check valves can be made from various materials like brass, stainless steel, or plastic, and are crucial in many industrial and residential applications. If you have a shipment of PVC check valves, they would also be classified under this HS-6.
When classifying your products, consider the specific design and intended use of the valve. For instance, a valve designed for a boiler system would still fit under this code, while a valve used solely for pressure reduction would not.
