2024-06-26 10:33:11 CCFGroup

On May 27, 2024, the Ministry of Industry and Information Technology revised the "Standardized Conditions for the Viscose Fiber Industry (2017 Edition)" and the "Interim Measures for the Administration of the Announcement of Standardized Conditions for the Viscose Fiber Industry", forming the "Standardized Conditions for the Viscose Fiber Industry (2024 Edition)" and the "Administrative Measures for the Announcement of Standardized Conditions for Viscose Fiber Enterprises". The new version is similar to the old one in terms of content framework, mainly adding content related to carbon emissions, and other details have been modified, supplemented or deleted.

2017 edition	New, deleted or adjusted content in the 2024 edition
Introduction	Emphasis on preventing low-level duplication and reducing resource waste	Emphasis on promoting green transformation and reasonably guiding the direction of industry development
Enterprise layout	Emphasis on new construction in non-specific areas	Emphasis on concentrated construction of new projects in industrial parks
	The construction of new VFY projects are prohibited. Strictly control the construction of new VSF projects. New projects must have the conditions of replacing traditional raw materials such as cotton linter pulp and wood pulp through independent development, and realizing pulp and fiber integration, or having raw material bases that match the new capacity.
