Industry Code for Environmental Protection Mobile Toilets
There is currently no separate and specific industry code for environmental protection mobile toilets; they are generally classified under the category of Environmental Protection Special Equipment Manufacturing (C3591). Here is a detailed explanation:

Basis for Industry Code Classification
Industry codes are standardized coding systems used to classify and statistically analyze different industries. In China, they are primarily determined based on the 'National Economic Industry Classification' standard. This standard meticulously categorizes various economic activities, aiming to provide a unified and standardized basis for economic statistics and policy formulation. For environmental protection mobile toilets, there is currently no independently established industry code specifically targeting them.
Possible Classification Directions
Although environmental protection mobile toilets do not have a dedicated industry code, based on their functions and characteristics, they can be classified under the category of Environmental Protection Special Equipment Manufacturing (C3591). Environmental Protection Special Equipment Manufacturing mainly involves the production of various equipment used for preventing and controlling environmental pollution and improving environmental quality. Environmental protection mobile toilets possess environmental treatment functions, such as treating excreta through biodegradation, physical filtration, and other technologies to reduce environmental pollution, thus fitting within the scope of environmental protection special equipment. For example, Jiangsu Yuyuan Environmental Protection Equipment Co., Ltd. has its national standard industry clearly marked as Environmental Protection Special Equipment Manufacturing (C3591), and the company is likely engaged in businesses related to environmental protection mobile toilets, which indirectly indicates that the business of environmental protection mobile toilets can be included in this category.
Situation in Practical Applications
In practical economic activities and statistical work, due to the uniqueness of environmental protection mobile toilets, some enterprises may further subdivide and explain within the broad category of Environmental Protection Special Equipment Manufacturing based on their own business focuses and product characteristics. However, overall, before a more precise industry code is introduced, Environmental Protection Special Equipment Manufacturing (C3591) is a relatively appropriate and commonly used classification method that can cover the production, sales, and other related business aspects of environmental protection mobile toilets.
