Alphabetic Index of Products and Services of Mineral Establishments This index provides an alphabetic list of products and services classified in the mineral industries for which data are shown in file NC92F6 of the industry reports. The references in this index refer to items for which statistics are either shown separately in that table or are included as part of a group of products or services. The index also includes products and services referred to in the industry descriptions in the explanatory text of the separate industry reports. References to products may be found in various tables in the industry chapters; however, detailed product information is typically given in file NC92F6. The industry codes are based on the 1987 edition of the Standard Industrial Classification (SIC) Manual published by the Office of Management and Budget.
