U.S. exports of kaolin, clay, ceramic & refractory minerals mining (NAICS 212323) totaled $78.1M in July 2026.
Importers of Kaolin, Clay, Ceramic & Refractory Minerals Mining paid $215K in duties in July 2026 — an effective duty rate of 12% on $1.8M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataKaolin and ball clay extraction underpins supply chains for ceramics, paper coating, rubber compounding, and high-temperature refractory products used in steel and glass furnaces. Domestic production is concentrated in Georgia (kaolin) and the Southeast, but trade professionals tracking imports must distinguish raw crude clay from beneficiated or calcined grades, as processing level affects HTS classification and applicable duty treatment. Refractory minerals such as kyanite and andalusite serve distinct industrial end-uses from ceramic-grade kaolins, making precise grade identification critical at entry.

Crude or simply dried kaolin typically falls under a different HTS heading than calcined or surface-treated kaolin. Importers should confirm the degree of beneficiation with their supplier before entry, as calcined grades may carry different duty rates and may be subject to separate antidumping orders depending on origin.
Refractory minerals (e.g., kyanite, sillimanite, andalusite) are valued for extreme heat resistance and are classified separately from ceramic-grade kaolins or ball clays. The end-use application — steel furnace linings versus porcelain or paper coating — drives both the HTS subheading and any applicable end-use certificate requirements.
