Yes, Section 301 tariffs have applied to glazed ceramic tiles from China, one of the historically significant supplier countries for this category. Importers have responded by diversifying sourcing to other origins and by carefully documenting country of origin to ensure correct duty assessment. CBP scrutinizes origin claims for ceramic tile given the history of transshipment concerns, so robust supply chain documentation — including mill certificates and production records — is advisable.

While slip-resistance ratings (such as DCOF or PEI wear ratings) are commercial and building-code specifications rather than tariff classification criteria, they are critical to end-use suitability and buyer specifications. Glazed tiles intended for floor use must meet applicable ANSI or ASTM slip-resistance standards for the installation environment. Importers should obtain test reports from suppliers confirming the relevant ratings, as misrepresentation of floor-use suitability can create product liability exposure independent of customs classification.
