Addressing Leather Processing Challenges with High-Purity Tanning Oxalic Acid 99.6% (HS Code: 29171110)
We've witnessed countless leather manufacturers struggle with inconsistent tanning results caused by low-purity oxalic acid—uneven dye absorption, prolonged processing cycles, and excessive waste from副反应. In our 10+ years serving leather industries across 50+ countries, purity fluctuations as small as 0.5% have led to batch rejections and production delays.
A Stable and Reliable Industrial Oxalic Acid Supply Solution
Our China Tanning Oxalic Acid 99.6% addresses these critical issues through stringent quality control. As a leading chemical export platform with 6,000+ global industrial customers, we ensure each batch maintains 99.6% purity, eliminating the variability that disrupts leather processing workflows. Our monthly production capacity of 6,000 tons guarantees consistent supply even for large-scale tanneries.
Typical Industrial Applications
This Industrial Grade Oxalic Acid serves as a vital auxiliary in leather processing, facilitating deliming, degreasing, and pH adjustment stages. Its reducing properties make it effective in metal surface treatment and mining operations, while its cleansing capabilities support stone cleaning applications. All uses strictly adhere to industrial manufacturing standards, with no applications involving human consumption.
Why Key Specifications Matter for Leather Processing
The 99.6% purity level minimizes impurities that cause uneven collagen fiber swelling during deliming, ensuring uniform leather texture. Its medium strong acidity (pH 1.3 in 0.1M solution) provides precise pH control critical for enzyme activation in bating processes. With a melting point of 101-102ºC and solubility in water/ethanol, it offers stable performance across various processing temperatures and solvent systems. The white powder form ensures accurate dosing and easy dissolution, reducing material waste and processing time.
What You Gain With Our ISO9001 Oxalic Acid
Choosing our ISO9001 certified Tanning Oxalic Acid delivers measurable benefits: reduced reject rates by up to 30% compared to lower purity alternatives, consistent processing times that improve production scheduling, and compliance with international leather standards. Inferior oxalic acid risks leather embrittlement from excess calcium removal or color distortion from heavy metal impurities—costly issues our strict quality control eliminates. Our stable supply chain prevents production halts, protecting your profit margins.
Why You Can Trust Our China Oxalic Acid
Every batch undergoes comprehensive testing including HPLC purity analysis, heavy metal screening (Pb, As, Hg below 1ppm), and moisture content verification (<0.5%). We provide batch-specific COA documents with full test results, and MSDS for safe handling. Our production facility in Shandong operates under ISO9001 standards, with SGS-audited quality management systems. If any parameter fails to meet specifications, we offer full replacement or refund—no questions asked. Our technical team provides free application guidance to optimize your tanning processes.
Certificate of Analysis & Documentation
Each shipment includes a Certificate of Analysis with exact purity data, impurity profiles, and physical property measurements specific to that batch. Safety documentation includes MSDS with handling precautions, storage requirements, and emergency procedures. For quality verification, customers can request access to raw chromatographic data (HPLC) for their specific batch by providing the order number.
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.
