Harmonized System Code Classification

The first two digits "85" represent Electrical Machinery, Apparatus, and Parts Thereof.

Specifically, this chapter covers the following main categories:

• Vacuum tubes and semiconductor devices: Including diodes, transistors, integrated circuits, etc.
• Electrical components: Such as resistors, capacitors, inductors, transformers, etc.
• Electronic integrated circuits: Including microprocessors, memory, etc.
• Receivers and associated equipment for broadcasting and television: Including televisions, radios, cameras, etc.
• Telephones, telegraphs, and radio communication equipment: Including mobile phones, walkie-talkies, radio transmitters, etc.
• Radar and radio navigation equipment:
• Instruments and apparatus for industrial or scientific use: Including measuring, controlling, and testing instruments, etc.
• Instruments and apparatus for medical, surgical, dental, or veterinary use:
• Other electrical equipment: Including vending machines, security inspection equipment, etc.

In summary, the HS code "85" chapter mainly refers to various types of electrical equipment and related components, covering a wide range of electronic technologies and devices used in modern society.

If you can provide a more specific HS code (such as 8517), I can provide a more detailed classification explanation.

The first four digits "8547" refer to:

Insulating fittings for electrical machinery, apparatus, or equipment, which are entirely made of insulating material, except for a small amount of metal parts incorporated during the molding process for assembly purposes (e.g., threaded sockets); insulators not covered under heading 8546; electrical conduits and their fittings lined with insulating material on a base metal.

Six-digit explanation:

HS code: 8547.90

Classification: Insulating fittings for electrical machinery, apparatus, or equipment, entirely made of insulating material, except for a small amount of metal parts incorporated during the molding process for assembly purposes (e.g., threaded sleeves), not including insulators under heading 8546; electrical conduits and their fittings lined with insulating material on a base metal.

Specific meaning: Refers to insulating fittings for electrical machinery, apparatus, or equipment, entirely made of insulating material, except for a small amount of metal parts incorporated during the molding process for assembly purposes (e.g., threaded sleeves), not including insulators under heading 8546; electrical conduits and their fittings lined with insulating material on a base metal.

8-10 digit explanation:

HS code: 8547900020

Classification: Other insulating fittings → Electrical conduit tubing and joints therefor, of base metal lined with insulating material → Conduit tubing

Explanation: This HS code belongs to insulating fittings for electrical equipment, apparatus, or devices, entirely made of insulating material, except for a small amount of metal parts incorporated during the molding process for assembly purposes (e.g., threaded sleeves), not including insulators under heading 8546; electrical conduits and their fittings lined with insulating material on a base metal, specifically classified as: Other insulating fittings → Electrical conduit tubing and joints therefor, of base metal lined with insulating material → Electrical conduit tubing.

Examples of products: - PVC insulated electrical conduit - Metal conduits with insulating coating - Insulated electrical connectors - Insulated wire guides - Plastic insulated electrical tubes
