Is this made in USA?

We appreciate your input, however as the largest tank trim supplier to OEM toilet manufacturers, we must manufacture and supply our products from large scale production plants nearby their facilities. Toilet manufacturers must locate their ceramic production facilities near abundant sand reserves, hence primary toilet production in Mexico and China. We are proud to be headquartered in the United States, with extensive engineering, warehousing, finance, sales and marketing operations here but by virtue of being the trusted suppliers to all of the major toilet manufacturers, we need to support their operations from our production facilities near their factories. Korky on the other hand, is not selected as a capable supplier by major toilet manufacturers and their sales are typically limited to United States aftermarket retailers, hence their tendency to manufacture here.
