Use this as a comparison hint, then confirm the final decision with legal notes and country-specific rules.
HS-4 · Heading
8404 — Auxiliary plant for use with boilers of heading no. 8402 or 8403; e.g. economisers, super-heaters, soot removers, gas recoverers), condensers for steam or other vapour power units
Chapter 84: Nuclear reactors, boilers, machinery
Plain-language overview
Use HS-4 8404 when importing auxiliary plant equipment designed for use with boilers classified under headings 8402 or 8403. For example, if you're bringing in a super-heater that enhances steam production, this is the correct code. Understanding the specific type of auxiliary equipment is crucial for accurate classification.
When deciding between the subheadings, consider the specific function of your equipment. HS-6 840410 covers items like economisers and soot removers, which directly assist in boiler efficiency. In contrast, HS-6 840420 is for condensers, which are crucial for steam or vapor power units. Make sure to match your product's primary function to the right subheading.
If your shipment includes parts rather than complete units, you should look at HS-6 840490. This subheading is for components of auxiliary plants and condensers, such as valves or heat exchangers. Ensure you identify whether your goods are complete systems or parts to select the appropriate classification.
