Products classified under Tariff item 2804.10
Fuel Cell Grade Hydrogen
>- Fuel cell grade hydrogen is a high-purity elemental gas (≥99.97%) used as a fuel in proton exchange membrane (PEM) fuel cells for vehicles and stationary power systems. It is a separate chemical element of Chapter 28, meeting the criteria of Note 1(a) to Chapter 28, and is not excluded by Chapter 27 since it is not a petroleum or hydrocarbon fuel. The product is classified under tariff item 2804.10.00 as hydrogen, regardless of its end use.
2804.10.00High-Purity Hydrogen for Laboratories
>- High-purity hydrogen for laboratories is an ultra-pure elemental gas (99.999%) used as a carrier gas or fuel in analytical instruments such as gas chromatographs and spectrometers. It is a separate chemically defined element of Chapter 28, meeting the purity and form requirements of Note 1(a). The product is classifiable under tariff item 2804.10.00 as hydrogen, with no further processing or admixture.
2804.10.00Industrial Grade Hydrogen Gas
>- Industrial grade hydrogen gas is compressed elemental hydrogen used in welding, metal cutting, chemical synthesis, and other manufacturing processes. It is a separate non-metal element of Chapter 28, meeting the criteria of Note 1(a) as a chemically defined element, even if it contains minor impurities. The product is classifiable under tariff item 2804.10.00 as hydrogen, regardless of its industrial application.
2804.10.00Liquid Hydrogen for Rocket Propulsion
>- Liquid hydrogen for rocket propulsion is hydrogen in a cryogenic liquid state (-253°C), used as a fuel in aerospace applications. The physical state does not affect its classification as a separate chemical element under Chapter 28, and it meets the criteria of Note 1(a). It is classifiable under tariff item 2804.10.00 as hydrogen, with no exclusions for end use.
2804.10.00Medical Hydrogen Inhalation Gas
>- Medical hydrogen inhalation gas is pharmaceutical-grade hydrogen used in therapeutic inhalation devices, meeting USP standards. It is a chemically defined element of Chapter 28, and its medical use does not exclude it from heading 28.04, as Chapter 28 covers separate elements regardless of application. The product is classifiable under tariff item 2804.10.00 as hydrogen, provided it is not put up in measured doses for retail sale.
2804.10.00Welding Hydrogen Gas Cylinder
>- Welding hydrogen gas cylinders contain hydrogen gas for oxy-hydrogen welding torches, supplied in large cylinders. The hydrogen is a separate chemical element meeting Chapter 28 Note 1(a), and minor stabilizers or impurities are permitted under Note 1(d) if necessary for preservation or transport. It is classifiable under tariff item 2804.10.00 as hydrogen, as it is not a mixture with other gases.
