Msds oxalic acid

When purchasing Oxalic Acid (Ethanedioic Acid), the most critical factor is the purity level, typically categorized as Industrial Grade (99.6% min) or Refined/Pharmaceutical Grade. For B2B buyers, ensure the product is Oxalic Acid Dihydrate (C2H2O4·2H2O) if intended for general industrial use. Key parameters to verify in the COA (Certificate of Analysis) include low heavy metal content (Lead/Arsenic < 10ppm), low ash content (< 0.08%), and chloride levels (< 0.002%) to prevent unwanted chemical reactions in your specific application.

As a hazardous chemical, Oxalic Acid must be accompanied by a GHS-compliant MSDS (Material Safety Data Sheet) or SDS. Ensure the supplier provides documentation matching the UN Number (UN 3261) and Hazard Class 8 (Corrosive). For export to the EU, verify REACH registration; for the US, ensure TSCA compliance. The packaging must feature standardized hazard pictograms (Skull and Crossbones or Corrosive symbol) and bilingual labeling to pass through customs without seizure.

Oxalic Acid is highly versatile. In the textile and leather industry, it is used as a bleaching agent and mordant. In metallurgy, it serves as a rust remover and metal polisher. For wastewater treatment, it acts as a precipitant for rare-earth elements. Additionally, it is widely used in the pharmaceutical sector for synthesizing antibiotics and in the commercial cleaning industry for floor polishing and wood restoration.

Due to its corrosive nature, Oxalic Acid is typically packed in 25kg or 50kg PP/PE woven bags with an inner plastic liner to prevent moisture absorption and leakage. For large-scale procurement, 1000kg jumbo bags (FIBC) are more cost-effective. Ensure the bags are UV-stabilized and palletized with shrink-wrap to maintain stability during sea freight and prevent 'caking' caused by humidity.

The primary risks include quality inconsistency (purity drops) and customs delays due to improper documentation. To mitigate these, always request a pre-shipment inspection (PSI) by third parties like SGS or Intertek. Furthermore, ensure the supplier is a verified manufacturer on Made-in-China.com with a proven track record of handling hazardous chemicals to avoid 'ghost' suppliers who lack export licenses for restricted substances.

Chemical prices fluctuate with raw material costs (like synthetic gas or sodium formate). Negotiate based on Incoterms 2020, preferably FOB or CIF, to clarify insurance responsibilities. For orders exceeding 20 Metric Tons (1 FCL), aim for a volume discount of 5-10%. Always clarify the lead time, as hazardous goods require specialized booking with shipping lines, which can take 7-14 days longer than general cargo.

Utilize Secured Payment services provided by reputable platforms like Made-in-China.com to ensure funds are only released upon proof of shipment (Bill of Lading). Avoid direct wire transfers to personal accounts. For first-time orders, use a Letter of Credit (L/C) for high-value transactions to ensure the supplier meets all documentary requirements before payment is executed.
