Includes brass mills, wire-rod mills, foundries, ingotmakers, chemical plants, and other manufacturers. 2/Apparent consumption represents primary refined production plus production from all old scrap plus net refined imports plus refined copper stock changes. New refined and remelted scrap is not included. 3/Apparent consumption represents primary production plus all copper from old and new scrap plus net refined imports plus refined copper stock changes. 4/Refined inventories include Government-held stocks. 5/Import reliance is calculated as a percentage of apparent consumption, primary refined copper plus old scrap. 6/Average number of weeks of available stocks based on average weekly apparent consumption for the year. 7/U.S. producers price, annual average, delivered refined copper.
