The seasonally unadjusted prices for materials used in glass and glazing manufacturing were positive in June and in year-over-year price changes, 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 was up 2.5% and 6.5% from June 2020. 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 June index for flat glass manufacturing in the industry classification rose 6.0% from May 2021 and 12.0% 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 were up from last month’s PPI report. That index, in the commodity grouping, is up 25.0% from a year ago and up 5.7% from May. The index for ornamental and architectural metal product manufacturing, in the industry category, shot upwards, increasing 1.9% from May to June 2021 and 26.6% from June 2020.

The PPI for metal windows increased 2.4% and climbed 10.9% compared to the June 2020 report. The price for metal doors and frames is also up, 4.1% from May and 13.7% for the year.

The cost of builders’ hardware, including glass and glazing, also increased from the May 2021 report with a 5.9% increase and rising 9.3% over June 2020.
