Harmonized System Code Classification

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

Specifically, this major category includes the following main contents:

• Nuclear reactors, boilers and parts thereof: Including nuclear reactors, boilers, auxiliary equipment, etc.
• Machinery: Covers a very wide range, including:
  • Engines, internal combustion engines, turbines, etc., for power generation
  • Pumps, compressors, fans, etc., general-purpose machinery
  • Lifting, conveying, loading, unloading, and handling equipment
  • Special-purpose machinery for agriculture, construction, mining, etc.
  • Special-purpose machinery for printing, textile, food processing, etc.
  • Machine tools, machine equipment, etc.
• Electrical equipment: Including:
  • Generators, transformers, motors, etc., electrical power equipment
  • Wires, cables, switches, sockets, etc., electrical components
  • Broadcasting, television, telephone equipment, computers, etc., communication equipment
  • Lighting, heating, air conditioning equipment
  • Weighing instruments, measuring instruments, etc.
• Parts and accessories of the above equipment: Covering all parts and replacement parts of the above equipment.

In short, the HS code "84" represents various core equipment used in industrial production and energy supply, as well as their related components.

If you can provide a more specific HS code (e.g., 8407, 8411, etc.), I can give you a more detailed classification explanation.
