Centrorochas' participation is part of the institutional and industry diplomacy strategy the association has been pursuing since July 2025, when the first proposed tariff measures were announced. Since then, the organization has been working closely with Brazilian companies, U.S. importers, distributors, trade associations and other American stakeholders to defend the interests of the natural stone supply chain.

During the hearing, the Brazilian Natural Stone Association (Centrorochas) will present arguments demonstrating the potential effects of the proposed tariffs on U.S. businesses, jobs, investments and supply chains, while reinforcing the rationale for excluding Brazilian natural stone products from the proposed measures. Key points include the use of these materials by American companies in downstream processing, fabrication, distribution and installation, the lack of equivalent substitutes for many applications, and the potential impacts of the measures on construction and housing costs in the U.S.

The submission presented by Centrorochas highlights that approximately 99.9% of Brazilian natural stone exports to the U.S. consist of semi-finished stone slabs used by American companies in fabrication, distribution and installation activities. In 2025, Brazil exported US$795 million in natural stone to the U.S., its largest international market, totaling approximately 587,000 metric tons of materials primarily used in kitchen and bathroom countertops, wall and floor cladding, and other high-end residential and commercial applications.

The submission presented to the USTR is also supported by key stakeholders across the U.S. natural stone supply chain, including the Natural Stone Institute (NSI), the leading trade association representing the U.S. natural stone industry; Pacific Shore Stones, a distributor operating 17 locations across six U.S. states; and Quality Marble & Granite, a leading supplier serving Southern California and Arizona. In their statements, these organizations emphasize the lack of equivalent substitutes for many Brazilian natural stone products and warn that the proposed tariffs could increase costs and negatively affect investments throughout the supply chain.

According to Cruz, Centrorochas' submission to the USTR represents another milestone in the association's ongoing strategy of trade advocacy, institutional diplomacy and industry diplomacy, pursued since last year to demonstrate the importance of Brazilian natural stone to the U.S.

“Brazilian natural stone does not compete with domestic U.S. production,” said Cruz. “On the contrary, it complements a supply chain that supports jobs, investments and economic activity across multiple states. Excluding our sector from the proposed measures is aligned with the economic interests of the U.S. industry and will help preserve the competitiveness of companies that depend on these materials while avoiding additional costs for consumers.”
