The not seasonally adjusted prices for materials used in glass and glazing manufacturing rose nearly across the board in June, 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 is up 0.4% from the previous month, but is up 1.8% from June 2019. 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 increased 0.4% from May 2020. It’s up 0.5% 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 have increased 0.5% from last month’s PPI report. That index, in the commodity grouping, is up 0.2% from a year ago. The index for ornamental and architectural metal product manufacturing, in the industry category, was unchanged from May to June 2020. It has experienced a 1.2% jump since June 2019.

The PPI for metal windows was unchanged from the May 2020 index. It has climbed 3.3% compared to the June 2019 report. The price for metal doors and frames is up a slight 0.1% from May 2020. The category is up 1.4% for the year.
