2015 Annual Revision Industry Code Changes

The table below shows the changes to the IP indexes published in the G.17 release at the time of the annual revision issued on July 21, 2015. With this revision, the classification system for the industry groups was advanced to the 2012 version of the North American Industry Classification System (NAICS), and the comparison base year was advanced to 2012. As part of the reclassification from the 2007 NAICS to the 2012 NAICS, the following changes were made to the published indexes.

Reclassification from the 2007 NAICS to the 2012 NAICS
IP Code (2007 NAICS) IP Description (2007 NAICS) IP Code (2012 NAICS) IP Description (2012 NAICS)
G325188A Acids, phosphates, and sulfates NAICS=325188pt. Discontinued (index ends in 2012 but available upon request)
G325188 All other basic inorganic chemical NAICS=325188 Discontinued
G325188Z Other inorganic chemicals NAICS=325188pt. Discontinued (index ends in 2012 but available upon request)
G331411 Primary smelting and refining of copper NAICS=331411 G33141C Primary smelting and refining of copper NAICS=33141pt.
N221112A9 Fossil fuel and other electric power generation NAICS=221112,9 N221112A4T8 Fossil fuel and other electric power generation NAICS=221112,4-8

N331316 Aluminum extruded product NAICS=331316 N331318E Aluminum extruded product NAICS=331318pt.
N331419 Primary smelting and refining of nonferrous metal (except copper and aluminum) NAICS=331419 N33141N Primary smelting and refining of nonferrous metal (except copper and aluminum) NAICS=33141pt.
G33441@1 Semiconductors and related equipment Discontinued

The definition of the "selected high-technology industries" IP aggregate has changed with this revision. Under the 2007 NAICS, this aggregate excluded electron tubes (NAICS 334411), but under the 2012 NAICS, electron tubes have been merged into other electronic components (NAICS 334419) and are thus included in the aggregate. IP indexes that either include or exclude selected high-technology industries now include or exclude all of semiconductors and other electronic components (NAICS 3344). The following indexes are affected by the change.
