HS-6 · Subheading
848140
Valves; safety or relief 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 848140 when importing or exporting safety or relief valves designed for pipes, boiler shells, tanks, or vats. For example, a shipment of pressure relief valves used in a chemical processing plant would fall under this code.
This code specifically covers safety or relief valves, which are crucial in preventing overpressure situations in various systems. In contrast, HS-6 848141 pertains to other types of valves like pressure-reducing valves, which serve a different function.
Safety and relief valves under 848140 are typically constructed from materials like brass or stainless steel and are used in applications ranging from industrial machinery to residential heating systems. This distinguishes them from general valves that may not have the same safety features.
When classifying products, consider whether your valves are designed specifically for safety applications. If they are standard valves without safety features, you may need to look at other codes under this heading.

- What types of valves are classified under HS-6 848140?
- HS-6 848140 covers safety or relief valves designed for use in pipes, boiler shells, tanks, and vats. These valves are specifically engineered to prevent overpressure situations.
- Can I use HS-6 848140 for valves used in residential heating?
- Yes, if the valves are safety or relief valves designed for residential heating systems, they can be classified under HS-6 848140.
- What is the difference between HS-6 848140 and HS-6 848141?
- HS-6 848140 is for safety or relief valves, while HS-6 848141 is for pressure-reducing valves, which serve a different purpose in regulating pressure.
- Are there specific materials required for safety valves under HS-6 848140?
- Safety valves under HS-6 848140 are typically made from durable materials like brass or stainless steel to ensure reliability and safety in high-pressure applications.
- What documentation do I need for importing safety valves?
- You will generally need a commercial invoice, packing list, and any relevant safety certifications or compliance documents for the valves being imported.
- How do I know if my valve qualifies as a safety valve?
- A valve qualifies as a safety valve if it is specifically designed to prevent overpressure and has features that ensure it opens at a predetermined pressure level.
- Can I classify a standard valve under HS-6 848140?
- No, standard valves without safety features should be classified under different codes. Only valves specifically designed for safety applications belong under HS-6 848140.
- What are the common applications for safety valves classified under HS-6 848140?
- Common applications include steam boilers, gas pipelines, hydraulic systems, and various industrial machinery where pressure regulation is critical.
