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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If doped for electronics or semiconductor use
Chemically doped rare gases for electronic applications shift to heading 3818 per Chapter 28 note, as they are no longer simple chemically defined elements.
If mixed with other gases or in retail fire-extinguisher charges
Mixtures or preparations of rare gases fall outside Chapter 28 per note 2, into 3824 for chemical preparations not elsewhere specified.
If containing more than 95% xenon
Xenon-specific subheading within 2804.30 applies when purity thresholds are met, distinguishing from generic 'other' rare gases.

Import Tips & Compliance
• Obtain material safety data sheets (MSDS) and purity certificates to verify classification as chemically defined rare gas under Chapter 28
• Comply with DOT and PHMSA regulations for compressed gas cylinders, including proper labeling and pressure testing documentation
• Avoid misclassification as mixed gases (HTS 3824); declare exact purity to prevent customs holds
