Harmonized System Code Classification

The first two digits of the HS code "84" represent "Nuclear reactors, boilers, machinery, and mechanical and electrical equipment, 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., power machinery
  • Pumps, compressors, fans, etc., general machinery
  • Cranes, conveyors, loading and unloading equipment, handling equipment
  • Special machinery for agriculture, construction, mining, etc.
  • Special machinery for printing, textiles, food processing, etc.
  • Machine tools, machine tools, etc.
• Electrical equipment: Including:
  • Generators, transformers, motors, etc., power equipment
  • Wires, cables, switches, sockets, etc., electrical components
  • Broadcasting and television equipment, telephone equipment, computers, etc., communication equipment
  • Lighting, heating, air conditioning equipment
  • Scales, measuring instruments, etc.
• Parts and accessories of the above equipment: Covers 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 and their related parts.

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

8-10 digit explanation: hscode: 8409913000 classification: Parts suitable for use solely or principally with the engines of heading 8407 or 8408: --> Other: --> Suitable for use solely or principally with spark-ignition internal combustion piston engines (including rotary engines): --> Other: --> To be installed in vehicles of subheading 8701.21, 8701.22, 8701.23, 8701.24 or 8701.29, or heading 8702, 8703 or 8704: --> Aluminum cylinder heads

Explanation: This HS code belongs to parts applicable to engines under headings 8407 or 8408, more specifically parts applicable to spark-ignition internal combustion piston engines (including rotary engines). These parts are specifically used for installation in vehicles under subheadings 8701.21, 8701.22, 8701.23, 8701.24 or 8701.29, or headings 8702, 8703 or 8704, and are aluminum cylinder heads.

Product Examples: * Aluminum cylinder heads for internal combustion engines * Aluminum engine blocks * Aluminum valve covers * Aluminum intake and exhaust manifolds * Aluminum engine mounting brackets
