In a direct communication, the source explains: 

Starting from data for January, industry-specific capacity utilisation rate data and data on industry E Water supply; sewerage, waste management and remediation activities are no longer produced. Total industry comprises industries BCD.

In response, we have archived the series (2010=100, January 1995 to December 2017) by renaming with "_10" specifier and by marking their metadata as "discontinued". Figures are percent (%) not seasonally adjusted (NSA). The classification is TOL 2008, the national adaptation of NACE Rev. 2.

The series reside in the historical catalog (Finland » Industry » Capacity utilization » 2010=100 [DISCONTINUED]) and include, for example: 

• CU%MQ_10UM.IFIN = [DISCONTINUED] Capacity utilisation rate: Mining and quarrying [B], (%, NSA)
• CU%28_10UM.IFIN = [DISCONTINUED] Capacity utilisation rate: Manufacture of machinery and equipment n.e.c. [28], (%, NSA)

Because catalog locations are subject to change, the upper-right search box on DataBuffet.com provides a "find in catalog" mode that accepts a mnemonic.
