Harmonized System Code Classification

HS code: 84
Description: Machinery, mechanical appliances, and electrical equipment, and parts thereof.
Explanation: The first two digits "84" represent nuclear reactors, boilers, machinery, mechanical appliances, and electrical equipment and their parts. This chapter includes a wide range of products such as nuclear reactors, boilers, steam generators, turbines, engines, pumps, compressors, machine tools, agricultural machinery, construction machinery, industrial robots, generators, transformers, electric motors, wires and cables, switchgear, lighting equipment, electronic tubes, semiconductor devices, telecommunications equipment, radio and television equipment, etc. The classification is based on the function and purpose of the product, whether it is used for nuclear energy utilization, energy conversion, power drive, material processing, or the generation, transmission, and reception of electrical signals. In short, if a product is used to produce, convert, transmit, or utilize energy, or perform mechanical processing, material handling, or electrical signal processing, it is likely to fall under Chapter 84 of the HS code.

HS code: 8405
Description: Producer gas or water gas generators, with or without purifiers; acetylene gas generators and similar water treatment gas generators, with or without purifiers; their parts.
Explanation: This classification includes producer gas or water gas generators, whether or not equipped with purifiers, acetylene gas generators, and similar water treatment gas generators, whether or not equipped with purifiers, as well as their parts.

HS code: 8405.90
Description: Producer gas or water gas generators, whether or not with purifiers; acetylene gas generators and similar water treatment gas generators, whether or not with purifiers; their parts.
Explanation: This refers to producer gas or water gas generators, acetylene gas generators, and similar water treatment gas generators, whether or not equipped with purifiers, as well as their parts.

HS code: 8405900000
Description: Producer gas or water gas generators, with or without purifiers; acetylene gas generators and similar water treatment gas generators, with or without purifiers; their parts.
Explanation: This HS code classifies producer gas or water gas generators, acetylene gas generators, and similar water treatment gas generators, whether or not equipped with purifiers, as well as their parts.

Examples of products under this HS code: - Water gas generator (without purifier) - Producer gas generator with purifier - Acetylene gas generator (for industrial use) - Parts of a water treatment gas generator - Components of a producer gas generator - Accessories for acetylene gas generators - Gas generator parts used in chemical plants - Water treatment gas generator (for industrial water processing)
