Products classified under HTS 2804.29.00.55
Krypton Gas Cylinder
High-purity krypton gas, a rare noble gas, supplied in compressed cylinders for industrial applications such as laser technology and lighting. It falls under HTS 2804.29.0055 as 'other' rare gases excluding helium, neon, and argon, per Chapter 28 notes for chemically defined nonmetals. This classification applies to pure krypton in gaseous form, not mixed or organo-inorganic compounds.
Xenon Gas for Lighting
Pure xenon gas used in high-intensity discharge lamps and flash photography, packaged in high-pressure cylinders. Classified under HTS 2804.29.0055 as other rare gases, aligning with Chapter 28 for elemental nonmetals excluding common rare gases. Excludes mixtures or organo-compounds per chapter exclusions.
Xenon Calibration Gas
Pure xenon gas cylinder for calibrating mass spectrometers and gas chromatographs in analytical labs. Falls under HTS 2804.29.0055 as other rare gases, chemically defined per Chapter 28 notes, excluding mixtures or organo-inorganic bonds.
Research-Grade Krypton
Ultra-high purity krypton (>99.999%) for scientific research in spectroscopy and particle physics experiments. It is a chemically defined rare gas under HTS 2804.29.0055, within Chapter 28's scope for nonmetals, distinct from doped or mixed forms excluded by notes.
Industrial Krypton for Lasers
Compressed krypton gas for excimer lasers in semiconductor manufacturing and medical procedures. Classified in HTS 2804.29.0055 for other rare gases as elemental nonmetals under Chapter 28, not as preparations or doped materials.
High-Purity Xenon Bulbs Gas
Xenon gas for filling automotive HID headlight bulbs, supplied pure in cylinders. HTS 2804.29.0055 covers this as other rare gases, per Chapter 28 for chemically defined nonmetals excluding exclusions like mixtures.
