Welding 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.
