The not seasonally adjusted prices for materials used in glass and glazing manufacturing were a mixed bag in November 2019, according to the latest Producer Price Index (PPI) from the U.S. Bureau of Labor Statistics (BLS). However, most prices are up year-over-year.

In November, the monthly PPI for flat glass in the commodity category grew 0.4% from the previous month, and is up 1.3% from November 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 November index for flat glass manufacturing in the industry classification rose 0.8% from October 2019. It’s up 1.9% 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 are down 0.5% from last month’s PPI report. That index, in the commodity grouping, is down 1% from a year ago. The index for ornamental and architectural metal work manufacturing, in the industry category, is up a slight 0.1% from October to November 2019. It has experienced a 0.1% increase since November 2018.

The PPI for metal windows has decreased 0.1% this month from its October 2019 index. However, it has jumped 4.6% compared to the November 2018 report. The price for metal doors and frames is unchanged in November. However, the category is up 1.2% for the year.

The cost of builders’ hardware, including that used in glass and glazing, showed no change this month but a 0.7% increase compared to the November 2018 report.
