Durable goods orders reflect the new orders placed with domestic manufacturers for immediate and future delivery of factory hard goods. The first release, the advance, provides an early estimate of durable goods orders. About two weeks later, more complete and revised data are available in the factory orders report. The data for the previous month are usually revised a second time upon the release of the new month's data.
Durable goods orders are available nationally by both industry and market categories. A new order is accompanied by a legally binding agreement to purchase for immediate or future delivery. Advance durable goods orders no longer include data on semiconductors since semiconductor manufacturers stopped releasing this information to the Census Bureau.
The advance durable goods report also contains information on shipments, unfilled orders and inventories. Shipments represent deliveries made, valued at net selling price after discounts and allowances, excluding freight charges and excise taxes. Unfilled orders are those received but not yet delivered.
In 2001, the Census Bureau shifted from the standard industrial classification (SIC) system to the North American Industrial Classification System (NAICS). This caused some realignment of major industry classifications. Given the significant revisions incurred, the historical data now begin in 1992.
