Sodium Sulphate Anhydrous
China Sodium Sulphate Anhydrous supplier offering mineral-process and by-product grades, with COA comparison, samples, export packing and RFQ support.
Jinan ZZ International Trade Co., Ltd. supplies Sodium Sulphate Anhydrous from China for detergent, glass, textile, paper, dyeing and other industrial buyers. The product is also known in China as Yuanming Powder (元明粉). We support COA review, source comparison, export packing, port-based quotation and shipment document coordination.
Product Overview
Sodium Sulphate Anhydrous is a white inorganic salt with the chemical formula Na2SO4 and CAS No. 7757-82-6. It is commonly used as a filler, processing aid and raw material in detergent powder, glass manufacturing, textile dyeing, paper, sodium silicate and other chemical processes.
China supplies both mineral-process material and material recovered as a by-product from other chemical processes. Buyers should specify the intended application and required quality indicators before quotation.
Mineral Process and By-Product Quality
Mineral-process Sodium Sulphate is commonly selected when buyers require higher whiteness, lower and more stable impurity levels, and better batch-to-batch consistency. It is often preferred for detergent, glass, textile and other applications sensitive to color or impurities.
By-product Sodium Sulphate can offer a cost advantage and may be suitable for less sensitive industrial applications. However, its quality can vary according to the originating chemical process and purification method. Chloride, iron, calcium and magnesium, water-insoluble matter, moisture, pH, color and batch consistency require particular attention.
Origin alone does not determine final quality. Well-purified by-product material may meet demanding specifications, while mineral-process grades also differ between producers. Buyers should compare representative COA results, confirm the production route, request a sample when necessary and include acceptance limits in the sales contract.

Why Choose Us
We help overseas buyers compare Chinese mineral-process and by-product Sodium Sulphate sources instead of treating all grades as interchangeable. Before order confirmation, we can coordinate specification review, sample evaluation, COA checking, packing confirmation and shipping documents.
Frequently Asked Questions
What is Yuanming Powder?
Yuanming Powder is the common Chinese trade name for Sodium Sulphate Anhydrous, with the formula Na2SO4.
What is the difference between mineral-process and by-product Sodium Sulphate?
They differ mainly in raw-material source and production route. Mineral-process material is often selected for whiteness and stable impurity control, while by-product material may offer lower cost but requires closer review of impurities and consistency.
Is mineral-process material always better?
Not automatically. Final suitability depends on the actual COA, purification process and application. Buyers should compare specifications and samples rather than relying only on the source description.
Which quality items should buyers compare?
Important items include Na2SO4 purity, chloride, iron, calcium and magnesium, water-insoluble matter, moisture, pH, whiteness and batch consistency.
Can you supply 99% Sodium Sulphate Anhydrous?
Standard high-purity industrial grades commonly target 99% minimum. The exact value and impurity limits must be confirmed against the current supplier COA and contract.
Can you provide a sample before bulk order?
Sample availability can be checked. For source-sensitive applications, sample approval is recommended before confirming a regular order.
What packing options are available?
Common options include 25 kg bags, 50 kg bags and 1,000 kg jumbo bags. Palletized packing can be discussed.
Can you quote both mineral-process and by-product grades?
Yes. Please state the intended application and target specification so we can compare suitable sources and quotations.
What information is required for an RFQ?
Please provide production-route preference, specification, packing, quantity, destination port, Incoterm and required documents.
