7323.91 - Of cast iron, not enameled:

This HTS category, 7323.91, specifically addresses household articles and their parts, along with pot scourers and similar items, made from cast iron that are **not enameled**. This broad classification encompasses a wide array of common kitchenware, cookware, and other domestic items crafted from cast iron, such as frying pans, Dutch ovens, and skillets, provided they lack any enameled coating.

Distinguishing this category from its siblings is crucial for accurate classification. Unlike 7323.92.00, which covers enameled cast iron items, or 7323.93.00 and 7323.94.00 which specify stainless steel or other iron/steel articles (enameled or not), 7323.91 is solely for bare cast iron. The "Other" designation within the parent 7323.9 category highlights that these cast iron articles are neither specified by material (like stainless steel) nor by a particular finishing process (like enameling in other sibling categories).

Within 7323.91, further subdivisions exist to refine classification based on specific surface treatments. The subcategory 7323.91.10.00 is reserved for cast iron articles that have been coated or plated with precious metal, a distinct characteristic that sets them apart from more common household items. The remaining items under 7323.91.50 fall into the "Other" classification, encompassing all cast iron household articles that are not enameled and not plated with precious metal, representing the residual scope of this code.
