Inorganic Acids: Types, Uses, and How to Source from China


Inorganic acids are vital raw materials in industries ranging from pharmaceuticals to agriculture. Their versatility and cost-effectiveness make them indispensable for manufacturers worldwide. This guide explores their types, functions, and how to source them reliably from China.


Types of Inorganic Acids


Common inorganic acids include sulfuric acid, hydrochloric acid, nitric acid, and phosphoric acid. Each has unique properties:

  • Sulfuric Acid: Widely used in fertilizer production and petroleum refining.
  • Hydrochloric Acid: Essential for metal cleaning and food processing.
  • Nitric Acid: Key in explosives and dye manufacturing.
  • Phosphoric Acid: Used in food additives and detergents.

Functions and Features of Inorganic Acids


These acids are known for their high reactivity, solubility, and ability to form salts. For example, sulfuric acid’s dehydrating properties make it ideal for chemical synthesis, while hydrochloric acid’s low pH is perfect for industrial cleaning.


Scenarios of Inorganic Acids


Inorganic acids are used in:

  • Agriculture: Fertilizer production (e.g., phosphoric acid for phosphate fertilizers).
  • Manufacturing: Metal treatment and battery acid (sulfuric acid).
  • Food Industry: pH regulation and preservatives (citric acid derivatives).

How to Choose Inorganic Acids


Consider purity (industrial vs. reagent grade), concentration, and supplier reliability. For bulk purchases, verify certifications like ISO 9001 to ensure quality.


How to Find Reliable Inorganic Acids from China in 2025


China dominates global chemical exports. To source safely:

  • Use platforms like Alibaba to vet suppliers with trade assurance.
  • Request lab test reports (e.g., COA) for purity verification.
  • Check production capacity—top suppliers handle 10,000+ metric tons annually.

What Buyers Should Know Before Buying Inorganic Acids from China


Key considerations:

  • Logistics: Acids often require hazardous material shipping.
  • Pricing: Compare FOB vs. CIF terms; bulk orders (20+ tons) reduce costs by 15-20%.
  • Compliance: Ensure suppliers meet REACH or FDA standards for your market.

Inorganic Acids Q & A


Q: What’s the shelf life of inorganic acids?
A: Most last 1-2 years if stored in sealed containers away from moisture.

Q: Can I import inorganic acids without special permits?
A: No—hazardous chemicals require MSDS and import licenses in most countries.

Q: How do I test acid quality upon delivery?
A: Use third-party labs to verify pH, concentration, and contaminants.
