Cheap China-everything!  Do not be fooled by the beautiful staged photos--this is a atrociously low quality product.  As others have noted, there are 30+ pieces, and 250+ pieces of hardware in this assembly.  It took me approximately 6 hours to assemble, with a drill.  The hardware is cheap metal, which strips, the engineered wood is low-density fiber board, with a foil finish that scratches easily.  On top of all these shortcomings, I was sent duplicate parts, with other parts missing, which made complete assembly of this desk impossible.  AVOID AT ALL COSTS!
