PPI to Update Weights for Net Inputs to Industries Indexes

Effective with the release of Producer Price Index (PPI) data for June 2026 on July 15, 2026, the Bureau of Labor Statistics (BLS) will update weight allocations for the Net Inputs to Industries indexes to reflect 2017 Input-Output (I/O) Accounts from the Bureau of Economic Analysis (BEA).

Net inputs to industries indexes measure the average change in prices for domestic inputs consumed by industries; these indexes exclude capital investment, labor, and imports. BLS determines the products to include in an industry input index based on BEA data. The Use of Commodities by Industries table provides, on an industry-by-industry basis, the set and dollar value of products that each domestic industry consumes during production. BLS calculates weights for each commodity in an industry input index based on shares from this table and revenue data from the U.S. Census Bureau. The gross weight of each commodity in an industry input index equals the share of the total value of the commodity that is consumed by the industry, multiplied by the Census revenue for that commodity. BLS then converts the gross weight to a net weight by removing the portion of the input value for the commodity that was produced by the industry. BLS uses the BEA Make of Commodities by Industries table to determine the portion of the value for the commodity that is produced by the industry. PPI commodity index weights continue to be based on shipment values from the 2017 Economic Census, which were applied in January 2023. It is the share of these commodity index weights allocated to the various net input to industry indexes that will be updated.

Please note, this update also applies to the BLS satellite inputs to industries price indexes, which exclude capital investment and labor, but include imports.

Prior to this update, all net inputs to industry indexes were based on 2012 data from BEA and 2017 Economic Census data from the U.S. Census Bureau.
