The Indian Institute of Material Management - IIMM was introduced as an All India Body in 1975 by merging three professional associations - The National Association of Material Management (which until 1966 was known as National Association of Purchasing Executives), the Materials Management Association of India (earlier known as Purchasing Officers' Association) and the Material Management Association of Hyderabad. The merged body was called Indian Association of Material Management (IAMM), which was later changed to Indian Institute of Material Management (IIMM). The merger gave birth to an institution that in its current form is the only professionally recognized body for material management in India. Indian Institute of Materials Management (IIMM) with its Headquarters at Mumbai, is the National Apex body representing a wide spectrum of professionals engaged in various facets of Material Management responsible for planning, sourcing, logistics & supply chain management. IIMM with its wide network of 44 branches and 19 chapters has over 8000 members drawn from public, government and private sectors.
