Harmonized System Code Classification

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

Specifically, this major category includes the following main contents:

• Nuclear reactors and boilers: Including nuclear reactors and their components, various types of boilers (e.g., water-tube boilers, smoke-tube boilers, oil-fired boilers, etc.).
• Machinery: Covers a very wide range, including:
  • Engines (internal combustion engines, turbine engines, etc.)
  • Pumps, compressors, fans, conveyors, etc.
  • Lifting, handling, loading, transportation, and lifting machinery
  • Machine tools, machine tools, metal processing machinery
  • Textile machinery, paper-making machinery, printing machinery, agricultural machinery, construction machinery, etc.
  • Office machinery (e.g., typewriters, copiers, calculators, etc.)
• Mechanical appliances: Including various tools, instruments, and equipment used for the manufacture, maintenance, and testing of the above machinery.

In summary, the HS code "84" represents a wide range of machinery and parts related to energy production, industrial production, transportation, agriculture, and other fields.

If you can provide a more specific HS code (e.g., 8410, 8479, etc.), I can provide a more detailed classification explanation.

First four digits explanation: HS code 8442

Classification: Printing machines, apparatus, and equipment (excluding machines of headings 8456 to 8465), for preparing or manufacturing plates, cylinders, or other printing components; plates, cylinders, and other printing components; plates, cylinders, and lithographic stones prepared for printing purposes (e.g., planed, grained, or polished); parts thereof.

Six-digit explanation: HS code: 8442.50

Classification: Machines, apparatus, and equipment for preparing or making plates, cylinders, or other printing components (excluding machines of headings 8456 to 8465); plates, cylinders, and other printing components (e.g., planed, grained, or polished); parts: --> plates, cylinders, and other printing components, prepared for printing purposes (e.g., planed, grained, or polished): --> other

Meaning: This HS code covers machines, equipment, and components used in the printing industry, specifically including equipment for preparing or making printing plates, cylinders, and other components, as well as plates, cylinders, and other components that have been processed and are ready for direct printing. The term "other" refers to other types of printing components not explicitly listed.

8-10 digit explanation: HS code: 8442501000
Classification: Machinery, apparatus, and equipment (other than the machines of headings 8456 to 8465), for preparing or making plates, cylinders, or other printing components; plates, cylinders, and other printing components; plates, cylinders, and lithographic stones, prepared for printing for printing purposes (e.g., planed, grained, or polished); parts thereof: --> plates, cylinders, and other printing components; plates, cylinders, and lithographic stones, prepared for printing purposes (e.g., planed, grained, or polished): --> plates
Explanation: This HS code belongs to the category of equipment for preparing plates, cylinders, and other printing components, printing components, printing cylinders, and lithographic stones, as well as parts prepared for printing purposes (e.g., planed, grained, or polished). It includes printing plates.
