The Guiding Catalogue for Industrial Structure Adjustment (2024 Edition) consists of three categories: encouragement, restriction, and elimination.

Encouragement mainly refers to technologies, equipment, and products that play an important role in promoting economic and social development;

Restrictions mainly refer to outdated process technology that does not meet industry access conditions and relevant regulations, which is not conducive to safe production and achieving carbon peak and carbon neutrality goals. It is necessary to urge the transformation and prohibition of new production capacity, process technology, equipment, and products;

The elimination category mainly refers to outdated processes, technologies, equipment, and products that do not comply with relevant laws and regulations, seriously waste resources, pollute the environment, pose serious safety production hazards, hinder the achievement of carbon peak and carbon neutrality goals, and need to be eliminated.

Those that are not encouraged, restricted, or eliminated, and comply with relevant national laws, regulations, and policies, belong to the allowed category.
