As the classification of copy paper is rather arbitrary, the international paper business lacks unified codes and standards for copy paper varieties. There is no comprehensive criteria for classification and every manufacturer introduces his own regulations (А, В, С, А+, В++, Д, etc.).
JSC “Mondi SLPK” produces paper for office equipment following the organization standard STO 00279404-001-2013 (as amended by №1). To obtain further information on paper classes go to the 'Characteristics' section.
In 2018 a national standard GOST for office paper types was issued. This document is to regulate paper classes (varieties).
