This decrease is the result of the 0.7% drop in prices recorded in "metallurgy", 0.5% in "clothing industry" and 0.3% in both "other non-metallic mineral product manufacturing" and "furniture manufacturing", explains the HCP in a briefing note on the industrial, energy and mining output price index of April 2020.
It is also due to the 0.4% drop in "woodworking and manufacture of articles of wood and cork" as well as stagnating prices in the "food industry" and the "chemical industry", the same source points out.
In addition, the output price indices for "extractive industries", "electricity generation and supply" and "water production and supply" also stagnated during April 2020.
