Oxalic acid

When purchasing Oxalic Acid, the primary focus should be on purity levels, typically categorized as Industrial Grade (99.6% min) or Refined Grade. You must verify the moisture content (usually <0.5%) and the levels of impurities such as sulfate, heavy metals (Lead/Iron), and chloride. For applications like metal polishing or textile bleaching, a consistent crystal size is crucial for uniform solubility and reaction rates.

As a chemical product, Oxalic Acid must be accompanied by a valid Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS) compliant with GHS standards. For entry into the EU, REACH registration is essential. If the product is intended for pharmaceutical or food-related cleaning, look for ISO 9001:2015 quality management certifications and ensure the supplier provides a Certificate of Analysis (COA) for every batch to guarantee traceability.

Oxalic Acid is widely used as a rust remover in metal treatment, a bleaching agent in the wood and textile industries, and a precipitating agent in rare earth processing. Functional requirements include high solubility in water and strong acidity for effective scale removal. Buyers should ensure the packaging is moisture-proof and acid-resistant (typically double-layered PE bags) to prevent caking and degradation during storage.

Oxalic Acid is classified as a Class 8 Corrosive Substance under the IMDG Code (UN Number 3261 or similar depending on concentration). It requires specialized hazardous goods packaging and labeling. You must work with freight forwarders experienced in DG (Dangerous Goods) handling. Ensure the supplier provides a 'Dangerous Goods Packaging Certificate' to avoid customs delays or vessel rejection at the port of loading.

To secure your investment, utilize Trade Assurance services provided by platforms like Made-in-China.com to protect payments until delivery is confirmed. It is highly recommended to commission a third-party inspection (such as SGS or BV) to perform pre-shipment sampling and testing of the chemical purity. Never settle for 100% upfront payment; a standard 30% deposit and 70% against the Bill of Lading (B/L) is common for verified suppliers.

Oxalic Acid prices are heavily influenced by the cost of raw materials like ethylene glycol and nitric acid. Monitor these commodity trends to time your purchase. Negotiate based on volume tiers; for example, ordering in full container loads (FCL) can reduce unit costs by 10-15% compared to LCL due to lower handling fees for hazardous materials. Requesting a long-term supply contract can also lock in stable pricing against market volatility.
