Last updated: August 2026 dataFeldspar is the most abundant group of rock-forming minerals and a foundational raw material for glass and ceramic manufacturing, classified under a single 10-digit line (2529100000). Turkey leads US imports of feldspar, reflecting the country's extensive deposits and established export infrastructure, with Spain and Mexico also notable suppliers. Importers should note that feldspar's alumina and alkali content — which varies by mineral type (orthoclase, albite, anorthite) — is a key commercial specification that affects suitability for glass batch versus ceramic body applications.

Feldspar originating in Mexico and meeting USMCA rules of origin qualifies for preferential tariff treatment under the United States-Mexico-Canada Agreement. Importers must obtain a valid USMCA certification of origin from the Mexican supplier and retain it for at least five years to support the preference claim.
Glass manufacturers typically require feldspar with tightly controlled iron oxide (Fe₂O₃) content — often below 0.1% — to avoid discoloration in the melt, while ceramic producers focus on alumina (Al₂O₃) and alkali (K₂O/Na₂O) ratios that influence firing temperature and glaze development. Commercial contracts and import documentation should specify these chemical parameters to avoid disputes at delivery.
