7321.90.10.00 - Cooking chambers, whether or not assembled

This category, HTS 7321.90.10.00, specifically enumerates "cooking chambers, whether or not assembled." It encompasses the fundamental enclosed space within a stove, oven, or similar appliance where food is heated or cooked. This includes both fully formed chambers ready for installation and components that, when assembled, constitute a cooking chamber, such as oven boxes or roasting compartments. The material must be of iron or steel, aligning with the broader scope of Chapter 73.

This classification is distinct from its siblings by its focus solely on the "chamber" itself, rather than integrated functional units or surface elements. For instance, it does not include top surface panels with burners or controls (7321.90.20.00), nor does it cover complete door assemblies (7321.90.40.00). While cooking chambers may be incorporated into these other parts, this specific subheading isolates the chamber as its own classification when presented as a distinct component.

As this is a leaf node, there are no further subcategories under 7321.90.10.00. Classification into this subheading relies on identifying the component as the primary cooking cavity, irrespective of whether it is a standalone unit or a pre-fabricated section awaiting integration into a larger appliance. The key defining characteristic is its function as an enclosed space designed for culinary preparation.
