Industrial Sodium Sulfate Supplier
YuXing supplies industrial sodium sulfate (Na₂SO₄), CAS 7757-82-6, for detergent, glass, textile, pulp and chemical-processing applications. The product is commonly supplied as a white crystalline powder, with the final assay, impurity limits, particle size and packaging confirmed for each inquiry or order.
Buyers should specify whether they require anhydrous sodium sulfate or another form and state the assay basis. For grade selection, provide the application, target specification, monthly quantity, bag size, destination port and required TDS, SDS or batch COA.

Sodium Sulfate Grade Selection by Application
| Application | Buyer Should Confirm | Why It Matters |
|---|---|---|
| Detergent manufacturing | Na₂SO₄ assay, moisture, bulk density, particle size and chloride | Supports consistent blending, flow and finished-product formulation |
| Glass production | Assay, iron, water-insoluble matter and particle size | Helps control batch consistency and unwanted contamination |
| Textile and dyeing | Assay, chloride, iron, solubility and solution clarity | Impurities and dissolution behavior can affect process consistency |
| Pulp and chemical processing | Assay basis, moisture, insolubles and process compatibility | The suitable grade depends on the actual chemical system and operating conditions |
Anhydrous Sodium Sulfate and Other Forms
“Sodium sulfate” can refer to anhydrous Na₂SO₄ or hydrated forms such as sodium sulfate decahydrate. They differ in water of crystallization and assay basis. Do not select a grade from the product name alone: confirm the required form, Na₂SO₄ content, moisture and application-specific impurity limits.
Sodium Sulfate Is Not Sodium Sulfite
Sodium sulfate (Na₂SO₄) and sodium sulfite (Na₂SO₃) are different chemicals and are not interchangeable. Sodium sulfate is widely used in detergents, glass and textile processing, while sodium sulfite is commonly selected for reducing or oxygen-scavenging duties. Confirm the required chemical formula before requesting a quotation.
Packaging, Storage and Documents
Typical packaging is 25 kg or 50 kg bags, subject to product form, order quantity and destination requirements. Keep bags sealed and dry, and follow the current product SDS and site procedures. Product-specific TDS/SDS and batch COA can be coordinated for the confirmed grade and order.
