High-purity chemical solutions delivered globally with certified standard quality control.
Oxalic Acid Dihydrate (H₂C₂O₄·2H₂O), a crucial dicarboxylic acid, presents as colorless crystalline substance widely respected in industrial chemical manufacturing. Our CE-certified Oxalic Acid 2H₂O is synthesized under strict quality guidelines to guarantee a minimum purity of 99.6%. The molecular structure features two water crystallization molecules, ensuring stability under normal atmospheric conditions and high solubility in water and ethanol.
For chemical procurement directors looking for international compliance, CE Certification represents more than a sticker; it dictates raw material traceability, non-toxic residue testing compliance, and environmental stewardship across the manufacturing chain. As a listed enterprise, Shandong Pulisi ensures complete transparency, offering precise batch documentation alongside international third-party certifications including SGS and ISO 9001:2015.
Industrial grade oxalic acid requires strict limits on heavy metals and sulfate content. Shandong Pulisi guarantees a lead content of < 0.001% and an iron content of < 0.002% in our premium grades, safeguarding your downstream catalytic processes.
Operating direct facilities close to major hubs including Qingdao Port, Tianjin Port, and Xinjiang border custom gates enables Pulisi to secure low freight rates and provide fast delivery options for containerized or bulk shipments.
Unveiling the structural advantages of our advanced manufacturing system and local industrial supply chain.
Located in the industrial heart of Shandong, China, Pulisi capitalizes on local raw materials (CO and Sodium Formate). This vertical integration insulates our pricing models from market volatility, allowing us to supply consistent monthly quotas to international purchasers.
We align our manufacturing standards with strict European Union directives. By holding complete CE certifications, K-REACH, and FAMI-QS documentation, we eliminate customs complications, giving buyers a smooth logistics path through major European ports.
We operate custom storage hubs near Qingdao, Tianjin, and crucial Xinjiang land border ports (Khorgos / Alashankou). This configuration guarantees dynamic dispatch options, minimizing transit times to North America, Western Europe, and Central Asian markets.

Oxalic Acid Dihydrate has a shelf life of 2 years when stored in dry, well-ventilated warehouses. Because it is sensitive to moisture and heat (which can trigger dehydration to anhydrous oxalic acid), it is important to keep the containers tightly sealed and stored away from incompatible compounds such as oxidizing agents and strong alkalis.
