Castellón is the Spanish province with the greatest weight of industry in its economy. With 36.6% of its GDP coming from industrial activity, the Castellón ceramics cluster stands out as a world leader in industrial clusters and is internationally known as the "Silicon Valley" of ceramics.

This cluster brings together the activities of the tile, frits, glazes and ceramic pigments, and machinery industries, as well as numerous auxiliary industries.

All the innovation that is developed around the production of ceramic tiles, and that subsequently expands to the ceramic industry in the rest of the world comes from the Castellón ceramics cluster. It is a ground-breaking cluster in a unique symbiosis brought about by the special closeness among the companies that make it up, and by the joint work among tile, pigment, and machinery companies to continue being pioneers and developing innovation in terms of both technical and aesthetic trends.

The cluster’s total turnover in 2025 exceeded 6.573 mill €, of which 70% was allocated to exports and the remaining 30% to the domestic market.

As for the number of direct employees, the cluster as a whole directly employed 21.678 workers in 2025, of whom 18,5% were employed by ANFFECC.

Alongside the industry, research and innovation institutes have emerged, such as the ITC (Ceramic Technology Institute), Jaume I University, CEEI Castellón (Centre for Innovative Companies), Espaitec (Innovation and Research Space), the ports of Castellón and Valencia—the main export route for our products—, and numerous other auxiliary industries like transport, distribution, hospitality, commerce, and services, which revolve around the ceramic industry.
