Combat Leather Processing Defects with 99.6% Purity Dihydrate Oxalic Acid (HS Code: 29171110)
We've witnessed countless production delays caused by inconsistent acid purity—leather tanneries reporting uneven dye absorption, stone cleaning workshops struggling with residue buildup, and manufacturers facing unexpected batch failures. In our 10+ years serving industrial clients, the most common complaint remains: "Why can't we get stable raw materials that meet specifications every time?"
A Stable and Reliable Dihydrate Oxalic Acid Supply Solution
Our Industrial Grade Dihydrate Oxalic Acid addresses these challenges through rigorous quality control and规模化 production. With a monthly capacity of 5000 tons and ISO9001 certification, we ensure consistent 99.6% purity that minimizes副反应 in leather processing and guarantees effective stone cleaning results. This stability has made us the trusted partner for over 6,000 industrial customers across 50+ countries.
Typical Industrial Applications
As a key Leather Processing Chemical, this Dihydrate Oxalic Acid serves as an efficient cleaning and deliming agent, removing calcium deposits from hides to improve tannin penetration. In stone cleaning operations, its medium strong acidity effectively dissolves mineral stains without damaging substrate integrity. The product also finds applications in mining as a reducing agent and various industrial cleaning processes.
Why Key Specifications Matter
The 99.6% purity level is critical for industrial processes—lower concentrations introduce impurities that cause uneven reactions in leather treatment, leading to flawed finished products. Its defined melting point (101-102ºC) ensures predictable thermal behavior during processing, while solubility characteristics (soluble in water/ethanol, insoluble in benzene) allow precise formulation control. The 25kg bag packaging maintains product integrity during storage and transportation, preventing moisture absorption that could compromise performance.
What You Gain With Our Industrial Oxalic Acid
Choosing our Dihydrate Oxalic Acid means eliminating production disruptions from substandard raw materials. Unlike unreliable suppliers, our consistent quality reduces material waste by up to 15% in leather processing lines. The SGS-certified production process ensures compliance with international industrial standards, avoiding costly customs delays. With multiple loading ports (Qingdao, Tianjin, Shanghai), we guarantee 48-hour dispatch for urgent orders, protecting your production schedules from supply chain uncertainties.
Why You Can Trust Us
Every batch undergoes triple testing—initial raw material inspection, in-process HPLC analysis, and final COA verification—ensuring the 99.6% purity claim is backed by tangible data. We provide full traceability with batch-specific MSDS and test reports. Our 10+ years of chemical export experience means we understand international shipping regulations, handling documentation to prevent customs clearance delays. If any batch fails to meet specifications, we offer immediate replacement or full refund—no questions asked.
Certificate of Analysis & Documentation
Each shipment includes a detailed Certificate of Analysis with batch-specific purity test results, heavy metal content, and physical property measurements. MSDS documents are provided in multiple languages, compliant with REACH and OSHA standards. For critical applications, we can arrange third-party testing by SGS upon request, with results available within 72 hours of sample receipt.
Storage & Handling
- Store in a cool, dry, well-ventilated area, sealed and away from direct sunlight.
- Keep away from incompatible materials, food and feed sources.
- Handle with appropriate personal protective equipment (gloves, goggles, lab coat).
- Follow good industrial hygiene practices. Avoid inhalation and skin contact.
- Refer to MSDS for detailed storage and safety instructions.
