Prices for materials used in glass and glazing manufacturing in June 2019 were up on a year-over-year basis despite price decreases in several categories according to the latest Producer Price Index (PPI) from the U.S. Bureau of Labor Statistics (BLS).

In June, the monthly PPI for flat glass in the commodity category dropped 0.3% from the previous month, but is up 0.1% from June 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 continued its downward trend in June, dropping 0.8% from May 2019. However, it is up 0.2% 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 fell 1.1%, following a slight increase from April to May. That index, in the commodity grouping, is up 2% for the year. Ornamental and architectural metal work manufacturing, in the industry category, rose a modest 0.2% in June. It has experienced a 4.1% increase since June 2018.

The PPI for metal windows is unchanged from its May 2019 level. It’s up 8.8% from the June 2018 report a year ago. Metal doors and frames showed an increase of 0.2% in June. The category is up 4% for the year.

The cost of builders’ hardware, which includes hardware used in glass and glazing, fell 0.1% from May to June. However, that price is 3.4% higher than in June 2018.
