Classification depends on the article's principal use and design intent. If the dominant character is decorative — even with a minor functional element such as a small opening — customs authorities generally classify by the primary purpose. Importers should document the article's marketing context and design intent; a licensed customs broker can help assess borderline cases.

Both categories may be subject to Section 301 tariffs depending on the country of origin and the specific 10-digit HTS subheading. The applicable list and any product-specific exclusions can differ between the porcelain and non-porcelain headings, so importers should check the current USTR Section 301 annexes at the subheading level rather than assuming uniform treatment across ceramic ornamental categories.
