      basic introduction

      In order to promote energy conservation and environmental protection, with the approval of the State Council, from February 1, 2015, the consumption tax on coatings with a volatile organic compound (VOC) content greater than 420g/L under construction will be levied.

      Paint refers to the general term for a class of liquid or solid materials that can be applied to the surface of an object to form a solid coating with protection, decoration or special properties.

      The Chinese coatings industry defines VOC as "any organic compound with an initial boiling point less than or equal to 250 °C at a standard pressure of 101.3 kPa.

      standard test
