2. Strong acidity in a clear liquid form — effective for pickling, rust removal, ore leaching and water treatment pH adjustment.

3. YuXing provides TDS/MSDS/CoA documentation, flexible export packaging and Class 8 corrosive substance compliance support.

Frequently Asked Questions

What is hydrochloric acid used for in industry?

HCl is used in chemical synthesis, metal pickling and rust removal, ore leaching in mining, metallurgical cleaning and water treatment pH adjustment.

What is the difference between hydrochloric acid and sulfuric acid?

Hydrochloric acid is a volatile chloride-based acid suited to metal cleaning, pickling and chloride synthesis. Sulfuric acid (H₂SO₄) is a non-volatile acid for dehydration, fertilizer and high-temperature processes — selection depends on application chemistry.

What concentration does industrial hydrochloric acid require?

Industrial applications typically supply HCl at 36–38% concentration with ultra-low Fe, As, sulfate and heavy metal impurities. Typical market specifications may include the following; final specifications are confirmed by grade, batch and current documentation with CoA verification.

What is the HS code and hazard class for hydrochloric acid?

The export HS code is 2806100000. This is a Class 8 corrosive substance. YuXing provides TDS, MSDS and CoA to support customs clearance and regulated transport.

How is hydrochloric acid packaged for export?

YuXing supplies hydrochloric acid in export-standard packaging suitable for Class 8 corrosive chemicals, with packaging confirmed according to product grade, destination port, carrier requirements and applicable regulations.
