For over a decade, we’ve worked with industrial buyers across the globe on oxalic acid supply — and we know what matters most to you isn’t fancy technical jargon, it’s consistency you can count on. Stable purity, clean export-grade packaging, fast responses, and on-time shipments beat overly complex descriptions every time.

Today, oxalic acid is a workhorse across metal surface treatment, industrial cleaning, rare earth processing, textile manufacturing, and chemical production. While different industries call for different purity levels, most procurement decisions boil down to one question: Can your supplier deliver the same material, every batch, for years to come?

At SNOWHITE CHEMICAL CO., LTD, we focus on oxalic acid for industrial use, with full export support: from customs documentation and packaging customization to long-term supply planning tailored to your region.

What Is Oxalic Acid?

Oxalic acid is an organic acid offered in two primary commercial forms for global trade:

Oxalic Acid Dihydrate is the standard for bulk international shipments, while the anhydrous form caters to specialty applications requiring ultra-low moisture content.

Basic Product Information

While oxalic acid occurs naturally in plants, commercial demand is driven almost entirely by industrial processing and chemical manufacturing.

Physical and Chemical Characteristics

For industrial users, oxalic acid’s value comes down to two key properties: reducing power and chelating ability.

It reacts with metal ions, alkalis, and oxidizing agents to break down rust, scale, and oxide layers — which is why it’s the backbone of many industrial cleaning and surface treatment formulations. Unlike harsher mineral acids, it works without aggressive corrosion of base materials, making it ideal for precision applications.

Typical physical properties are shown below:

One of the biggest reasons oxalic acid remains a staple is its simplicity: it removes iron deposits, rust stains, and mineral scale without requiring complex, high-cost processing conditions. It also acts as a reliable reducing agent and precipitation material in many chemical processes.

Common Commercial Grades

Unlike citric or benzoic acid, oxalic acid is rarely used as a mainstream food additive globally. Most commercial demand is for industrial-grade material, with tiered options based on impurity control.

Industrial Grade Oxalic Acid

This is the most common grade for export markets, designed for general-purpose use.

Typical applications include:

• Rust removal solutions

• General metal surface cleaning

• Stone polishing and restoration

• Textile bleaching and processing

• Leather tanning and treatment

• Formulation of industrial cleaning chemicals

For bulk buyers, the biggest pain point isn’t whether oxalic acid works — it’s whether purity stays consistent batch-to-batch, so your cleaning formulations never need constant re-adjustment.

Surface Treatment & Precision Applications

Industries with strict quality requirements need tighter control over trace impurities, especially:

• Electroplating pre-treatment

• High-precision metal cleaning

• Surface finishing for aerospace/automotive parts

• Rare earth element processing

In these sectors, iron content, heavy metal impurities, and moisture levels are non-negotiable purchasing factors — even small variations can ruin a batch of finished goods.

Pharmaceutical & Fine Chemical Intermediate Applications

Oxalic acid is used as an intermediate in select pharmaceutical and fine chemical manufacturing processes.

Buyers in these sectors prioritize:

• Stable assay (purity) values

• Full batch traceability

• Complete export documentation (COA, MSDS, customs forms)

• Strict control over heavy metal and organic impurities

Always confirm specifications with your supplier to match your target application and local regulatory requirements.

Main Uses of Oxalic Acid

Oxalic acid’s stable global demand comes from its versatility — it’s not tied to a single industry, so supply chains remain resilient.

Metal Cleaning and Rust Removal

This is oxalic acid’s most widespread use.

It dissolves and lifts:

• Rust stains and iron oxides

• Hard mineral scale

• Oxide layers on steel, copper, and other metals

It’s widely used for equipment descaling, automotive parts cleaning, structural metal maintenance, and marine equipment restoration.

Textile and Leather Processing

In textile manufacturing, oxalic acid supports cleaning, bleaching, and pH adjustment for dye baths, helping ensure even color uptake and fabric softness.

Leather processors use it for surface treatment, deliming, and pH control during tanning to achieve consistent texture and finish.

Rare Earth Processing

Rare earth producers rely on oxalic acid for precipitation and separation. Its strong chelating properties selectively bind rare earth ions, forming pure, filterable precipitates that simplify downstream refining — a key advantage over other precipitants like sodium carbonate.

Industrial Cleaning Formulations

Oxalic acid is a key ingredient in specialized cleaning products for:

• Stainless steel passivation and cleaning

• Boiler and heat exchanger descaling

• Natural stone and tile cleaning

• Wood bleaching and restoration

Each formulation requires specific purity and impurity standards, so we work with buyers to match our material to your exact recipe.

Packaging, Storage and Transportation

Oxalic acid should be stored in dry, ventilated warehouses away from strong oxidizers and direct moisture exposure to prevent caking and degradation.

Our standard export packaging options include:

• 25kg inner plastic lined woven bags (bulk standard)

• Moisture-resistant kraft paper bags

• 1000kg jumbo bags for large-volume orders

We adjust packaging based on container loading conditions, customer requirements, and shipping routes. For long ocean voyages, we offer optional palletization and extra moisture barriers to keep material stable from factory to your warehouse.
