Overcoming Industrial Challenges with High-Purity Oxalic Acid (CAS 6153-56-6)
We’ve witnessed countless production delays caused by inconsistent oxalic acid purity—96%标称原料实际纯度波动至93%，直接导致皮革鞣制工序的铬盐利用率下降12%。实验室客户反馈更令人担忧：批次间的铁离子杂质差异（从5ppm到30ppm）使矿石浮选药剂的效果完全无法复现。作为10年专注化工供应链的服务商，这些因原料不稳定造成的损失本可避免。
Stable Supply of Industrial Grade Oxalic Acid for Critical Manufacturing
Our Oxalic Acid 96% and 99.6% grades address these pain points through strict ISO9001-controlled production. With a monthly capacity of 6000 tons and three loading ports (Qingdao, Tianjin, Shanghai), we ensure 45-day delivery stability even during peak seasons. This reliability has made us the preferred partner for leather processing plants in Turkey and mining operations in Australia, where consistent material quality directly impacts production yields.
Key Industrial Applications
In the leather industry, our 96% Oxalic Acid acts as an efficient cleaning and degreasing agent, preparing hides for tanning by adjusting pH levels without damaging collagen fibers. Mining operations utilize its strong chelating properties for mineral processing, particularly in separating calcium and iron minerals from ore deposits. Additionally, its reducing capabilities make it valuable for stone cleaning applications, where controlled dissolution of mineral deposits is critical.
Why Purity and Consistency Matter in Industrial Processes
The 99.6% purity level ensures minimal heavy metal impurities (≤10ppm), preventing catalyst poisoning in chemical synthesis. For leather manufacturers, the tightly controlled 96% grade balances reactivity and cost-effectiveness—higher purity would be unnecessary, while lower grades risk introducing sulfur compounds that discolor finished products. Our strict moisture control (<0.5%) prevents caking during storage, ensuring uniform mixing in dry formulations. Most importantly, batch-to-batch consistency (purity variation ≤0.2%) guarantees reproducible results in large-scale production.
Risk Reduction Through Quality Assurance
Using substandard oxalic acid can lead to costly consequences: leather batches with uneven dye absorption, mining reagents failing to meet environmental discharge standards, or cleaning solutions damaging historical stone surfaces. Our product eliminates these risks by complying with REACH regulations and undergoing SGS third-party testing. Customers report a 30% reduction in production waste after switching to our Industrial Grade Oxalic Acid, translating to significant long-term cost savings despite the slightly higher initial investment.
Our Quality Commitment
Every batch undergoes rigorous testing via HPLC for purity analysis and atomic absorption spectroscopy for heavy metal detection. We provide a comprehensive COA with each shipment, detailing 18 quality parameters including particle size distribution and insoluble matter content. Our 24-hour technical support team assists with application-specific adjustments, such as optimizing dissolution rates for mining slurries. With 10+ years of export experience to 50+ countries, we understand the documentation requirements for various customs authorities, ensuring smooth clearance.
Certificate of Analysis & Documentation
Each delivery includes a batch-specific Certificate of Analysis (COA) and Material Safety Data Sheet (MSDS) in English. For critical applications, we can arrange additional testing by independent laboratories upon request. Detailed chromatograms and impurity profiles are available for review prior to order confirmation, and retained samples are stored for 12 months for traceability.
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.
Streamlined Order Process for Industrial Buyers
Initiate your order by submitting an inquiry with your required purity grade and estimated monthly volume. We offer free sample testing (up to 500g) for qualification purposes, with results typically available within 3 business days. Once specifications are confirmed, our trade team provides clear pricing under FOB or CIF terms, along with a detailed production timeline. Regular customers benefit from dedicated account managers and priority scheduling during high-demand periods.
