Oxalic Acid for Industrial Buyers
Oxalic acid, also called ethanedioic acid, is a dicarboxylic acid commonly supplied as a white crystalline solid. Its acidity and metal-binding behavior make it useful in cleaning, bleaching and industrial synthesis. Buyers should confirm whether a specification is based on anhydrous material or a hydrate.
For stable processing, review assay, sulfate, chloride, iron and other application-sensitive limits on the product specification and batch COA. Qualification samples and destination-specific documentation can be discussed before a commercial order.
For an accurate offer, specify the intended application, target assay, critical impurity limits, shipment quantity, destination and preferred delivery term.

Common Oxalic Acid Applications
Final suitability depends on formulation, process conditions, grade and local regulatory requirements.
Metal cleaning and rust removal
Used in controlled formulations for oxide, stain and scale removal from suitable metal surfaces.
Textile processing
Applied as a mordant, bleaching aid or process chemical in qualified dyeing and finishing systems.
Wood and pulp bleaching
Used in selected bleaching and stain-removal processes where the approved formulation permits.
Stone and surface cleaning
An ingredient in professional cleaning products after substrate compatibility testing.
Chemical intermediates
A feedstock for oxalates and other downstream industrial or pharmaceutical chemistry.
Specialty processing
Used where acidity and chelating behavior support the validated manufacturing process.
Built for International Chemical Supply
Common export supply uses moisture-resistant bags with clear batch identification. Bag size, inner liner, palletization and container loading are confirmed for each order.
Confirm specification
Agree grade, assay, impurity limits, quantity and destination.
Approve packing and documents
Confirm container, labels, palletization, COA, SDS and shipping requirements.
Production and quality release
Traceable batch testing supports release against the agreed specification.
Loading and shipment
Coordinate container loading, export documents and delivery to the agreed port.
Oxalic Acid FAQ
Practical answers for sourcing, qualification, handling and export planning.
Is the supplied oxalic acid anhydrous or hydrated?
Commercial oxalic acid may be specified on different chemical bases. State the required form and assay method so the quotation and COA match your process.
What is the standard purity?
This page covers 99.6% industrial grade oxalic acid. Application-specific impurity limits should be included in the purchase specification.
Which applications use oxalic acid?
Common industrial uses include metal and surface cleaning, textile processing, bleaching and chemical intermediate production.
How should bags be stored?
Store sealed packages in a cool, dry, ventilated area protected from moisture and incompatible materials, following the SDS and local requirements.
Can I request a sample and COA?
A representative sample and recent COA can be discussed as part of supplier qualification before a larger shipment.
