I don't have specific information on "Simpatico Surfaces" or their partnerships or distribution rights for porcelain slabs as mentioned in your input. It appears to be a business-specific detail that might not be broadly documented or verified online, especially in widely accessible or authoritative sources. If you have more details or specific inquiries regarding their products, services, or areas of operation, I recommend directly contacting Simpatico Surfaces or visiting their official website for the most accurate and tailored information.
