Harmonized System Code Classification

The first two digits of the HS code "84" represent nuclear reactors, boilers, machines, mechanical appliances, and parts thereof.

Specifically, this chapter covers the following main categories:

• Nuclear reactors, boilers, steam generators, turbines, engines, pumps, compressors, machine tools, machine tools, agricultural machinery, construction machinery, industrial robots, etc.
• Electrical equipment and parts thereof: including generators, transformers, electric motors, wires and cables, switchgear, lighting equipment, electron tubes, semiconductor devices, telecommunication equipment, radio and television equipment, etc.

Reason for classification:

The classification of this chapter is based on the function and use of the product, i.e., whether the product belongs to nuclear energy utilization, energy conversion, power drive, material processing, or the generation, transmission, and reception of electrical signals. It covers various mechanical and electrical equipment that are essential to industrial production and modern society.

In short, if the product is used to generate, convert, transmit or utilize energy, or to perform mechanical processing, material handling, or electrical signal processing, it is likely to belong to Chapter 84 of the HS code.

The first four digits explanation: 8404: Auxiliary devices used with boilers under headings 8402 or 8403 (e.g., water-saving devices, superheaters, flue gas cleaners, heat recovery devices); condensers for steam or other steam power units; their parts.

6-digit explanation: HS code: 8404.10

Classification: Auxiliary boiler equipment and parts

Meaning: Applicable to auxiliary equipment (e.g., water-saving devices, superheaters, flue gas cleaners, heat recovery devices) for boilers under headings 8402 or 8403; condensers for steam or other steam power units; their parts. --> Applicable to auxiliary equipment for boilers under headings 8402 or 8403 --> Other

8-10-digit explanation: hscode: 8404100050 Classification: Auxiliary devices for boilers under headings 8402 or 8403 (e.g., water-saving devices, superheaters, flue gas cleaners, heat recovery devices); condensers for steam or other steam power units; their parts: --> Auxiliary devices for boilers under headings 8402 or 8403 --> Other Explanation: This HS code belongs to the other category of auxiliary devices for boilers under headings 8402 or 8403, specifically referring to auxiliary devices other than water-saving devices.

Examples of products: * Flue gas cleaner for industrial boiler * Heat recovery device for steam power plant * Condenser for steam turbine * Superheater for boiler system * Auxiliary parts for boiler systems
