In 2018, in order to speed up the improvement of environmental air quality, State Council proposed the "three-year action plan to fight air pollution".

On May 15th, 2020, the Ministry of Ecology and Environment issued the "2020 Volatile Organic Compounds Governance Plan (Draft for Comments)", which clearly stated that from July 1st, 2020, the production, sales and use of ship coatings and floor coatings should meet the newly promulgated and implemented national product harmful substance limit standards, architectural coatings and adhesive products in the Beijing-Tianjin-Hebei region must meet the requirements of the "Volatile Organic Compound Content Limit Standard for architectural coatings and Adhesives".

Summary of the new standard
