Producer gas or water gas generators, with or without their purifiers; acetylene gas generators and similar water process gas generators, with or without their purifiers; parts thereof
2 declarable lines
Heading 8405 covers gas generators that make fuel or process gas from a chemical or thermal reaction, such as producer gas generators, water gas generators, acetylene gas generators and similar water process gas generators, whether or not they include their purifiers. It also covers parts for those machines. The heading splits into one line for complete generators and one line for parts, and both carry a Free general (MFN) rate.
Products in this heading
- Producer gas generator set used to convert solid fuel into combustible gas
- Water gas generator
- Acetylene gas generator for welding or cutting shops
- Water process gas generator of the type used in industrial gas production
- Purifier unit presented with a gas generator
- Replacement retort, grate or burner assembly for a gas generator
- Spare parts for acetylene generators
How to choose the right subheading
- Whether the item is a complete gas generating machine or a part of one.
- The gas producing process: producer gas, water gas, acetylene, or another similar water process.
- Whether a purifier is presented with the generator, which stays in the same generator line.
- For parts, whether the part is solely or principally used with machines of heading 8405.
Often confused with
- Heading 8402Steam boilers and super-heated water boilers
Boilers raise steam by heat transfer; they do not generate gas by chemical reaction.
- Heading 8411Gas turbines
Turbines expand hot gas to produce power rather than generating the gas itself.
- Heading 8421Filtering or purifying machinery for gases imported on its own
Separately presented gas filters and purifiers belong to the general filtering heading.
- Heading 8414Air pumps, gas compressors and fans
These move or compress gas; they do not produce gas from a fuel or water process.
- Heading 8417Industrial or laboratory furnaces and ovens, nonelectric
Furnaces burn or apply heat; gas generation is a separate function.
Frequently asked questions
What is the HTS code for an acetylene gas generator?
Acetylene gas generators and similar water process gas generators, with or without their purifiers, are classified in 8405.10.00.00 at a general (MFN) rate of Free.
What is the duty on parts of gas generators?
Parts for the machines of heading 8405 are classified in 8405.90.00.00, and the general (MFN) rate is Free.
How do I classify a purifier imported separately from the gas generator?
A purifier presented on its own is treated as a part and classified in 8405.90.00.00 at a general (MFN) rate of Free. If it is presented together with the generator, the complete unit is classified in 8405.10.00.00 at a general (MFN) rate of Free.
