Application :

It is suitable for tanning harness leather, sole leather and sheepskin. It is recommended to store it in a cool, dry, ventilated warehouse. It is better to be used in combination with other tanning agents. 
It is mainly used for tanning. It can also be applied to the medicine, ink, printing, rubber and metallurgical industries as well as water treatment, etc. 
It can be used for tanning, fishing net dyeing, boiler cleaning, drilling, etc.
It can be used as analysis reagents as well as applied to the pharmaceutical industry.
It can be used for the pH adjusting of pelt pickling and vegetable tanning solution. It can be used for vegetable tanning rinse. Owing to its strong acidity, we shouldn't pack it in iron containers. It should be stored in a cool warehouse.
It can be used as a water-base drilling viscosity reducer and cement retarder.
In pharmaceutical industry, it can be used as the raw material for the preparation of gallic acid, pyrogallol and sulfa drugs. Tannin is a kind of hemostatic drug. In the field of medicine, it has ever been used for treating pharyngitis, tonsillitis, hemorrhoids and skin blistering disorders, internal application can curb diarrhea and intestinal hemorrhage. Tannin can react with metals, alkaloids and glycosides, etc to form precipitate with detoxification effect against these substances. Tannin can be used for leather tanning, manufacture of ink, paper and silk glue, boiler cleaning etc., it can also be used as mordent, the clarifying agent of beer and wine as well as the coagulant agent of rubber as well as reagents for the determination of beryllium, aluminum, nickel and copper. In the field of chemical production, it can be used for preparing gallic acid and gallic acid pyrophosphate. Tannin is used for dilution when dealing with the mud drilling. Mix the tannin powder in proportion with caustic soda can yield tannins alkaline solution which can reduce the shearing force of thickening mud and sticky mud, improving the flow of mud. On the contrary, if the tannin powder was added directly to the mud, due to its weak acidicity, the pH of the mud is reduced. Through the ion exchange with the clay particles, it reduces the hydration of the surface of the clay particle, leading to the formation of the network structure of the clay particles, improving the mud shearing force and viscosity. According to the provision of the GB2760-89 of China, "curing tannins" can be used for low degree wine and wine, as a clarifying agent for removing protein in its turbidity state and other suspended substances. In the food industry, it can also be used as astringent agents and crude oil deodorizer.
It can be used for the precipitation and weight determination of beryllium, aluminum, gallium, indium, niobium, tantalum and zirconium. It can also be used for the colorimetric assay of copper, iron, vanadium, cerium and cobalt. It can be used as the precipitating reagents of proteins and alkaloids. It can also be used as the external indicator in the titration of lead using molybdate.
