What parts are included under HS-840590?
Use this as a comparison hint, then confirm the final decision with legal notes and country-specific rules.
HS-6 · Subheading
Generators; parts of producer gas, water gas, acetylene gas and similar water process gas generators, with or without their purifiers
Heading 8405 — Generators for producer or water gas with or without their purifiers acetylene gas generators and similar water process gas generators, with or without their purifiers
Chapter 84: Nuclear reactors, boilers, machinery
Use HS-6 840590 when importing or exporting parts specifically designed for producer gas, water gas, or acetylene gas generators. An example would be a replacement filter for a water gas generator used in industrial applications.
This code is distinct from HS-6 840591, which covers complete gas generators. If you’re dealing with a fully assembled unit, you should classify it under that code instead.
Parts classified under this code include components like valves, pumps, and purifiers that are essential for the operation of gas generators. These parts are often critical for maintaining efficiency and safety in gas production processes.
When determining if 840590 applies, consider the end-use of the parts. Are they intended for maintenance of a gas generator? If so, this code is likely appropriate.
