Product Grades
Industrial Grade
Formic acid is available in concentrations of 85%, 90%, 94%, and 99%. The 85% grade represents the standard commercial concentration, whereas grades of 94% and higher are classified as high-purity industrial products. These are extensively employed in leather tanning, textile dyeing, rubber processing, and agrochemical synthesis.
Reagent Grade
Intended for laboratory applications, this grade is subdivided into chemically pure (CP), analytical reagent (AR), and guaranteed reagent (GR) classifications. GR-grade formic acid generally exhibits a purity of ≥98% or 99%, with rigorous specifications for chlorides, sulfates, ferric ions (≤0.0001%), and non-volatile residues.
Spectroscopic/Ultrapure Grade
Characterized by a minimum purity of 99.9% and negligible impurity profiles, this grade is reserved for high-precision spectroscopic analyses and specialized synthetic procedures. It is seldom stocked as a standard item and typically requires custom manufacturing.

Formic Acid Used in the Leather Industry
Formic acid is used as a deliming agent, neutralizing agent, and softening agent in leather processing, and also helps prevent wet leather from mildewing.
Formic Acid Used in the Textile Printing and Dyeing Industry
In textile dyeing and printing, formic acid is used as a dyeing auxiliary for acid dyes and nylon dyeing. It can replace sulfuric acid to avoid cellulose degradation and improve dye utilization efficiency.
Formic Acid Used in the Rubber Industry
Formic acid serves as a coagulant for natural rubber and a raw material for manufacturing rubber antioxidants.
Formic Acid Used in the Pharmaceutical Industry
Formic acid is an important pharmaceutical intermediate, commonly used in the synthesis of drugs such as caffeine, analgin, and vitamin B1.
Formic Acid Used in the Pesticide Industry
Formic acid is an important pesticide intermediate, used in the production of various high-efficiency insecticides and fungicides such as triadimefon and triazophos.
Formic Acid Used in the Agriculture Industry
In agriculture, formic acid is used as a preservative for silage to inhibit mold growth and improve feed palatability and fattening performance.
Formic Acid Used in the Semiconductor Industry
In vacuum eutectic soldering processes, formic acid vapor is used to reduce the oxide film on metal surfaces, eliminate bubbles in solder joints, and enhance the reliability and thermal dissipation performance of power chip packages (such as SiC and GaN).
Formic Acid Used in the Electroplating Industry
Because it contains no chloride ions and can dissolve metal oxides, formic acid is widely used in the cleaning of stainless steel equipment and in steel sheet pickling. In electroplating baths, it serves as an additive to regulate chromium ion concentration and improve coating stability.
