Industrial Formic Acid Supplier: Grades, Applications, Quality, and Purchasing Guide

A good Industrial Formic Acid Supplier should be more than competitive. Industrial buyers require stable concentration, controlled impurities and acceptable packaging, full technical documentation, good production capabilities, and reliable worldwide delivery.

Formic acid is used in leather tanning, textile finishing, rubber coagulation, animal feed preservation, treating silage, chemical manufacture, industrial cleaning, oilfield chemicals, agriculture and production of formate salt. These industries have varying processing needs and it is important to consider concentration, color, chloride, sulfate, iron, nonvolatile residue, water content, packaging compatibility, and batch consistency before making a purchase.

What Is Industrial Formic Acid?

Formic acid is the simplest carboxylic acid. Its chemical formula is HCOOH, and its CAS number is 64-18-6. It is normally supplied as a clear, colorless liquid with a strong odor and complete miscibility with water.

Typical product information includes:

• Chemical name: Formic Acid
• CAS number: 64-18-6
• Molecular formula: HCOOH
• Molecular weight: approximately 46.03
• Appearance: Clear, colorless liquid
• Solubility: Miscible with water
• EINECS number: 200-579-1
• Common concentrations: 85%, 90%, 94%, 98%, and 99%

The best grade depends on the application, required active content, process-water tolerance, storage system, transport method, and impurity specification.

Why Supplier Selection Matters

Two products with the same stated concentration may still perform differently because of variations in:

• Raw material quality
• Production technology
• Water content
• Chloride level
• Sulfate level
• Iron content
• Color
• Nonvolatile residue
• Storage conditions
• Packaging cleanliness
• Batch consistency

A professional supplier should control both the acid concentration and impurity profile.

It should also provide a batch-specific certificate of analysis rather than only a general technical data sheet.

Common Industrial Grades

Formic Acid 85%

Formic acid 85% is one of the most widely used industrial grades.

Potential advantages include:

• Broad availability
• Competitive cost
• Practical handling
• Easy dilution
• Wide industrial compatibility
• Suitability for drum, IBC, and bulk supply

It is commonly used in leather, textiles, rubber, feed preservation, cleaning, and general chemical processing.

Formic Acid 90%

The 90% grade offers higher active content and lower water content than the 85% grade.

Potential benefits include:
