7115 - Other articles of precious metal or of metal clad with precious metal:

HTS category 7115 encompasses articles primarily made of precious metals or metals that are clad with precious metals, which do not fall into more specific preceding headings within Chapter 71. This category is reserved for miscellaneous items of precious metal where the precious metal is a defining component, but the item's nature or function doesn't warrant placement in headings dedicated to jewelry, coin, or specific precious metal articles like tableware or industrial catalysts of platinum wire cloth.

Unlike sibling categories at the root level, which may cover live animals, machinery, or textiles, HTS 7115 is specifically nested within the broader scope of precious metals and articles thereof. Its distinction from other Chapter 71 headings lies in its residual nature. For instance, while precious metals are used in jewelry (7113), precious stones (7101-7104), or specific industrial applications like platinum catalysts (7115.10), category 7115 serves as a catch-all for other manufactured articles where precious metal is the principal element or cladding.

Within 7115, a primary subdivision exists: 7115.10.00.00 covers specific platinum catalysts in the form of wire cloth or grill, a distinct industrial application. The remaining articles fall under the broader subheading 7115.90, "Other." This further indicates that 7115 is a category for less common or more varied articles of precious metal, requiring careful consideration of material composition and intended use to ensure correct classification.
