Table IV-7 and figure IV-6 present data on apparent U.S. consumption and U.S. market
shares for quartz surface products adding in independent U.S fabricators during 2015-17,
January to September 2017, and January to September 2018. 19

The quantity for U.S. producers' U.S. shipments reflects the quantity of quartz surface products
sold in the United States from domestically manufactured slab (reported as fabricated quartz surface
products if reported by a fabricator, otherwise reported in slab format). Generally, fabricators indicated
that approximately 36 percent of the surface area of the quartz surface products was lost during the
fabrication process; this surface area explains in-part why the aggregated quantity data for these tables
are less than the aggregated quantity data reported by the slab producers. The value for U.S. producers'
U.S. shipments reflects the value of quartz surface products sold in the United States from domestically
manufactured slab plus the additional value added to imported slabs by U.S. fabricators. In measuring
consumption and market share this methodology avoids reclassifying and/or double counting
merchandise already reported once as an import or double counting merchandise between levels of
production on the domestic side.
