Hydrogen Water Generator
A hydrogen water generator is a device designed to infuse molecular hydrogen (H₂) into water. These devices operate on the principle of electrolysis, using electricity to separate water (H₂O) into its constituent elements, hydrogen and oxygen. The generated hydrogen gas is then dissolved in the water, creating hydrogen-rich water.
Material & Components
Typical components and materials include:
- Electrolysis Chamber: Often constructed from titanium with platinum-coated electrodes. Titanium is corrosion-resistant, and platinum enhances the efficiency of electrolysis. Some models use stainless steel electrodes, though these are generally less efficient and may have a shorter lifespan.
- Membrane: Proton Exchange Membrane (PEM) is frequently used in higher-end generators. PEM allows hydrogen ions to pass through while blocking other substances, resulting in purer hydrogen gas. Older or less expensive models may not utilize a membrane.
- Housing: Typically made of plastic or stainless steel for durability and water resistance.
- Control System: Includes a microprocessor, display screen, and buttons for controlling hydrogen concentration, operating time, and other settings.
- Water Reservoir: Usually made of BPA-free plastic.
- Diffusion Tube/Vent: Used to disperse the hydrogen gas evenly throughout the water.
Purpose & Function
The primary purpose of a hydrogen water generator is to produce water with a high concentration of dissolved molecular hydrogen. Molecular hydrogen is believed to have several potential health benefits, including:
- Antioxidant Properties: Hydrogen selectively neutralizes harmful free radicals, potentially reducing oxidative stress and cellular damage.
- Anti-inflammatory Effects: Some studies suggest hydrogen can reduce inflammation by modulating inflammatory pathways.
- Neuroprotective Effects: Research indicates potential benefits for brain health.
- Improved Metabolism: May enhance energy production and metabolic function.
The generator functions by:
- Electrolysis: Applying an electrical current to water.
- Gas Separation: Separating water molecules into hydrogen (H₂) and oxygen (O₂).
- Hydrogen Dissolution: Dissolving the generated hydrogen gas into the water.
- Oxygen Release: Venting the oxygen gas, often through a separate port.
Usage Scenarios
- Home Use: Personal consumption for potential health benefits.
- Wellness Centers: Providing hydrogen water as part of health and wellness programs.
- Sports Recovery: Utilized by athletes for faster recovery and reduced muscle fatigue.
- Medical Research: Used in studies investigating the therapeutic effects of hydrogen water.
Common Types
- Electrolysis-Based Generators: The most common type, utilizing electrolysis to produce hydrogen. These vary in efficiency, hydrogen concentration, and purity.
- Magnesium Reaction Generators: These generators use magnesium rods to react with water, producing hydrogen. They generally produce lower concentrations of hydrogen and require regular replacement of the magnesium rods.
- Hydrogen Tablets/Sticks: While not generators, these release hydrogen when added to water. Concentrations and duration of hydrogen production are limited.
- Alkaline Hydrogen Water Generators: Combine electrolysis with alkaline filtration to produce hydrogen-rich, alkaline water.
- Portable Hydrogen Water Bottles: Compact, battery-powered devices for generating hydrogen water on the go.
Based on the provided information, classifying a “hydrogen water generator” requires careful consideration of its function and components. Here’s a breakdown of potentially relevant HS codes:
- 8543709860: This code covers “Electrical machines and apparatus, having individual functions, not specified or included elsewhere in this chapter; parts thereof: Other machines and apparatus: Other: Other Other”. This is a broad category for electrical machines with unspecified functions. If the hydrogen water generator functions as a standalone electrical device producing hydrogen water without fitting into more specific categories, this code may apply. The total tax rate is 57.6%, comprised of a 2.6% base tariff, a 25.0% additional tariff, and a 30% additional tariff effective April 2, 2025.
- 8543906500: This code covers “Electrical machines and apparatus, having individual functions, not specified or included elsewhere in this chapter; parts thereof: Parts: Other: Printed circuit assemblies: Of flat panel displays other than for articles of heading 8528, except for subheadings 8528.52 or 8528.62”. If the hydrogen water generator contains printed circuit assemblies (PCAs) specifically for flat panel displays (not for articles in heading 8528, excluding 8528.52 or 8528.62), this code could be relevant. The total tax rate is 55.0%, consisting of a 0.0% base tariff, a 25.0% additional tariff, and a 30% additional tariff effective April 2, 2025.
- 8517690000: This code covers “Telephone sets, including smartphones and other telephones for cellular networks or for other wireless networks; other apparatus for the transmission or reception of voice, images or other data, including apparatus for communication in a wired or wireless network (such as a local or wide area network), other than transmission or reception apparatus of heading 8443, 8525, 8527 or 8528; parts thereof: Other apparatus for transmission or reception of voice, images or other data, including apparatus for communication in a wired or wireless network (such as a local or wide area network): Other”. If the hydrogen water generator incorporates communication features (e.g., remote control via a wireless network), this code might be applicable. The total tax rate is 55.0%, with a 0.0% base tariff, a 25.0% additional tariff, and a 30% additional tariff effective April 2, 2025.
It is important to note that the final classification depends on the specific features and functionalities of the hydrogen water generator. If the device includes components like plastic bottles or caps, HS codes 3923300090 or 3923500000 may also be relevant.
