Issues regarding the procedures for obtaining a permit to use concentrated sulfuric acid
Thread Content
Recently, the circulating water system at Shangjian was treated with concentrated sulfuric acid to increase the concentration ratio. But a license for using concentrated sulfuric acid is required. Have you ever obtained a usage permit? What are the specific procedures? Is it difficult to get this certificate? How long does it take to complete the process?
Sulfuric acid is considered a substance that can be used to manufacture drugs, so a purchase permit is required; you can inquire with the local public security bureau about this. However, since last year, such permits must be approved online, which makes the process rather complicated!
