Many of the prices for materials used in glass and glazing manufacturing in July 2019 were up on both a monthly and year-over-year basis according to the latest Producer Price Index (PPI) from the U.S. Bureau of Labor Statistics (BLS).

In July, the monthly PPI for flat glass in the commodity category grew 0.4% from the previous month, and 0.7% from July 2018. According to the BLS, the commodity classification “organizes products and services by similarity or material composition, regardless of the industry classification of the producing establishment.”

The index for flat glass manufacturing in the industry classification reversed the downward trend of previous months, increasing 0.7% from June 2019. It’s up 1.3% on a year-over-year basis. The industry classification measures “changes in prices received for the industry’s output sold outside the industry (that is, its net output).”

Prices for fabricated structural metal products grew 0.1% in July, following a 1.1% drop from May to June. That index, in the commodity grouping, is up 1% for the year.
