Is Oxalic Acid a Hazardous Chemical? An In-Depth Analysis Based on Standards and Properties
Oxalic acid (also known as ethanedioic acid) is a common organic acid used in laboratories, chemical production, and daily cleaning. However, there is widespread confusion about whether it is a strictly regulated "hazardous chemical." This article provides a detailed analysis from both Chinese national standards and international systems, clarifying common misconceptions.
Core Conclusion: Oxalic acid (ethanedioic acid) is classified as a hazardous chemical. The primary basis for this classification is not merely its inclusion in a specific list, but its inherent physical and chemical hazardous properties.

Zibo Anhao Chemical Co., Ltd. – Premium Oxalic Acid Supply
Zibo Anhao Chemical Co., Ltd. is a professional Chinese manufacturer and supplier specializing in high-purity Oxalic Acid (Ethanedioic Acid, CAS 144-62-7). With deep roots in China’s chemical industry base—Zibo, Shandong Province—we integrate advanced production technology, strict quality control, and efficient global supply chain to deliver consistent-quality oxalic acid for industrial and commercial applications worldwide.
Our oxalic acid is available in industrial grade (≥99.5% purity) and technical grade, presented as colorless, odorless crystalline solids (anhydrous or dihydrate forms) with strong solubility in water and ethanol. As a versatile dicarboxylic acid, it serves as a core raw material across key sectors:
Metal Treatment & Cleaning: Powerful rust remover, scale cleaner, and metal surface conditioner for steel, machinery, and equipment maintenance.
Textile & Leather Industry: Reliable mordant for dyeing, bleaching agent for pulpwood/straw, and tanning auxiliary for leather processing.
Chemical Synthesis: Key intermediate for producing oxalate salts (sodium oxalate, calcium oxalate), esters, and organic compounds like hydroquinone.
Pharmaceuticals & Agrochemicals: Precursor for antibiotics (tetracycline, chlortetracycline) and plant growth regulators.
Rare Earth Extraction: Selective precipitant for separating rare earth elements from industrial wastewater and minerals.
Backed by standardized production workshops, ISO 9001-compliant quality management, and third-party testing (SGS/BV), we guarantee stable product performance and batch consistency. We offer flexible packaging options (25kg plastic-lined drums, 1-tonne IBC tanks) and tailored logistics solutions to meet diverse customer demands—from small-batch orders to bulk global shipments.
Committed to “Quality First, Customer Centric”, Zibo Anhao Chemical strives to be your trusted long-term partner for high-quality oxalic acid and professional chemical solutions. Contact us today for detailed specifications, COA, or competitive pricing!
