Yes. Ceramic plumbing fixtures such as toilets, lavatories, and urinals must conform to ASME A112 and ANSI standards governing water consumption, dimensional fit, and performance. Many jurisdictions also require WaterSense certification for water-efficient fixtures. Importers should confirm that foreign manufacturers hold current third-party certifications before placing orders.

CBP distinguishes decorative from functional ceramic articles based on design, marketing, and actual use. Articles not designed or suitable for food or beverage use may be classified differently from tableware, affecting applicable duty rates. Importers should ensure that product descriptions on commercial invoices accurately reflect the article's intended use and that any decorative-only claims are supportable.
