Prices for materials used in glass and glazing manufacturing continued to edge up in February 2019, according to the latest Producer Price Index (PPI) from the U.S. Bureau of Labor Statistics (BLS).

In February, the monthly PPI for flat glass in the commodity category grew 1.7 percent from the same time a year ago and 0.1 percent from the previous month. 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 is up 2.3 percent from February 2018, though it decreased 0.7 percent from January 2019. 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 increased 0.8 percent from the previous month. That index, in the commodity grouping, is up 8.3 percent for the year. Ornamental and architectural metal product manufacturing, in the industry category, grew 0.1 percent in February. It has experienced a 7.6-percent increase from the previous year.
