The not seasonally adjusted prices for materials used in glass and glazing manufacturing increased almost across the board in March 2020, according to the latest Producer Price Index (PPI) from the U.S. Bureau of Labor Statistics (BLS).

In March, the monthly PPI for flat glass in the commodity category rose 0.4% from the previous month, and is up 1.8% from March 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 March index for flat glass manufacturing in the industry classification grew 1.2% from February 2020. It’s up 1.5% 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 0.3% from last month’s PPI report. That index, in the commodity grouping, is down 0.9% from a year ago. The index for ornamental and architectural metal product manufacturing, in the industry category, increased 2.1% from February 2020 to March 2020. It has experienced a 2.9% jump since March 2019.

The PPI for metal windows grew 2.1% from the February 2020 index. It has climbed 4.1% compared to the March 2019 report. The price for metal doors and frames is up a slight 0.3% from February 2020. The category is up 1.4% for the year.
