Soda Ash Supplier & Exporter — Dense and Light Sodium Carbonate
Na₂CO₃ Sodium Carbonate · Min 99.2%
High-alkalinity soda ash in both dense and light bulk densities, produced to ISIRI 614-1 and supplied to glass plants, detergent manufacturers, water utilities and chemical processors. Iron below 0.004% and water-insolubles below 0.1% in every grade, with a batch-specific Certificate of Analysis per shipment.

Grades & Chemical Analysis
Two bulk densities off the same 99.2% chemistry — dense granular for glass furnace batching, light powder for detergents and chemical dosing. Select a grade to view its full analysis.
Dense Grade — Granular, low-dusting
Dense Soda Ash
- Alkalinity (as Na₂CO₃)
- ≥ 99.2%
- Bulk Density
- 0.85 – 1.1 g/cm³
- Total Na₂O
- 57.85 – 58.42%
- Chloride (as NaCl)
- ≤ 0.4%
- Iron (Fe)
- ≤ 0.004% (30–50 ppm)
- Water Insolubles
- ≤ 0.1%
- Sodium Bicarbonate
- 0.1 – 0.5%
- Sodium Sulfate

Trace metals across both grades: Ni ≤ 30 ppm, Cr ≤ 10 ppm, Mn ≤ 10 ppm, Cu ≤ 65 ppm. Acceptance limits per ISIRI 614-1. Values are typical specification ranges; a batch-specific CoA is issued per shipment.
Dense Soda Ash — Particle Size Distribution
Sieve grading for the dense granular product, the property that governs segregation and dusting in a glass furnace batch house.
| Mesh Fraction | Passing / Retained | Specification |
|---|---|---|
| ≤ 20 mesh | Coarse fraction | Max 10% |
| 20 – 30 mesh | Upper mid fraction | Max 25% |
| 30 – 100 mesh | Main fraction | Min 60% |
| 100 – 140 mesh | Lower mid fraction | Max 7% |
| > 140 mesh | Fines | Max 3% |
Light soda ash is supplied as a fine powder and is specified on bulk density rather than sieve grading.

Applications
Soda ash is the highest-tonnage alkali in industry — the dense grade goes to glass, the light grade to chemicals and detergents.
Flat & Container Glass
Primary flux in float, bottle and jar furnaces.
Detergents & Cleaners
Builder and alkalinity source in household and industrial formulations.
Chemical Manufacturing
Feedstock for sodium silicate, nitrate and bicarbonate.
Water Treatment
pH correction and carbonate hardness adjustment.
Metallurgy & Non-Ferrous
Slag conditioning, lead refining and zinc extraction.
Pulp & Paper
Alkali make-up in pulping and de-inking.
Petrochemical & Refining
Acid gas neutralization and drilling-fluid alkalinity.
Ceramics & Glaze
Flux and deflocculant in tile and sanitaryware bodies.
Sugar Refining
Juice carbonatation and pH control.
Packaging, Logistics & Trading Terms
How we bag, certify and ship bulk soda ash. Terms can be adapted by agreement — tell us what your operation needs.
- Minimum Order Quantity
- 1 × 20 ft container (approx. 25 MT) bagged. 500 MT minimum for bulk vessel. Trial quantities available for qualification.
- Packaging
- Light grade: 25 kg, 50 kg, 700 kg and 1500 kg PP bags. Dense grade: 25 kg, 50 kg, 1000 kg and 1500 kg PP bags. Bulk loading on request.
- Incoterms & Loading Ports
- EXW, FOB, CFR and CIF (Incoterms® 2020). Standard loading at Bandar Abbas and Bandar Imam Khomeini; other ports by arrangement.
- Quality Certification
- Batch-specific CoA with every shipment covering alkalinity, NaCl, iron, insolubles and bulk density. SGS / Bureau Veritas inspection at buyer’s cost.
- Lead Time
- 7–14 days for standard grades after order confirmation; 15–25 days for custom-milled or specially packed material.
- Storage & Handling
- Store in a cool, dry, tightly closed container away from acids. Soda ash is hygroscopic — keep bags sealed and off the ground to prevent caking.
Certificate of Analysis
A batch-specific CoA is issued with every shipment. Third-party inspection by SGS, Bureau Veritas or an inspector of your choice can be arranged at the buyer’s cost.
