7311.00.00.90 - Other

This HTS code, 7311.00.00.90, covers "Other" containers for compressed or liquefied gas, made of iron or steel, that are not specifically addressed by other subheadings within heading 7311. These containers are designed to safely store gases under pressure, whether those gases are compressed, liquefied, or even dissolved under pressure. Examples include gas cylinders for industrial, medical, or recreational purposes, as well as larger storage tanks, provided they are constructed from iron or steel and are intended for the containment of compressed or liquefied gases.

This particular subheading is distinct from any explicitly defined sibling categories at this level within heading 7311. The structure of heading 7311 implies that other specific types of containers might be classified elsewhere under this heading, potentially based on unique certifications or specific design features not covered by this residual "Other" category. Therefore, when encountering an iron or steel gas container, the primary consideration is whether it fits into a more narrowly defined category before being considered for classification under this general subheading.

As a leaf node, this HTS category does not have further subdivisions. The classification hinges on meeting the general requirements of heading 7311 (containers for compressed or liquefied gas, of iron or steel) and not falling under any other more specific tariff treatment. The crucial factors for classification here are the material (iron or steel), the purpose (container for compressed or liquefied gas), and the absence of specific qualifying characteristics that would warrant a more detailed classification.
