Soda ash is sodium carbonate, but a quotation for “soda ash” can describe light or dense product, with different bulk density, particle size and flow, and impurity limits that matter very differently for glass, detergents and water treatment. This checklist is written for importers and factory buyers in Saudi Arabia and the wider GCC who want to compare suppliers on facts before asking for a price.
This is a buyer’s reference, not a PLAXRAW product specification. The material is described on the soda ash reference page. PLAXRAW does not publish prices or stock on this page; to discuss a requirement use the quotation request form, and any grade, availability and price are confirmed in writing for your enquiry.
Step 1: Fix the application before the grade
- Glass: soda ash is the main flux in a soda-lime batch, so iron content, particle size and consistent feeding matter more than headline purity.
- Detergents: bulk density, dissolution and flowability drive dosing and powder quality; iron and colour matter for white products.
- Water treatment and chemicals: the product must meet the specification of the standard or process you follow (for example ANSI/AWWA B201 for drinking-water treatment).
If you give a supplier only a price target and no application, the quotes you receive are not comparable. State the application and any standard you must meet.
Step 2: Specify the product, not just the name
| Item | What to ask for | Why it matters |
|---|---|---|
| Type | Light or dense, with the supplier grade name | Bulk density, flow, dissolution rate and dust differ between the two. |
| Sodium carbonate content | Na2CO3 content and the analysis method (for example ASTM E359) | Purity figures are comparable only when the method is the same. |
| Impurities | Iron (as Fe2O3), chloride (as NaCl), sulphate, insolubles | Iron affects glass colour and white detergent powders; chloride affects some process uses. |
| Particle size and bulk density | Size distribution and bulk density with the method | Control feeding, segregation and dissolution time. |
| Moisture and caking | Moisture or loss on heating, and storage guidance | Soda ash is hygroscopic and can cake in silos and bags. |
| Regulatory fit | SDS and any declaration your use requires | Food, feed or drinking-water use needs documents for that use; industrial grades do not cover it. |
Step 3: Ask for the documents that prove it
Request the current technical data sheet (TDS) and safety data sheet (SDS) for the exact grade, and ask whether a certificate of analysis (COA) is issued per shipment. A data sheet describes a product range; a COA reports the shipment. For glass or detergent production, ask for recent COA values for iron and particle size, and compare a sample from the commercial production route against your control material before approving volume.
Step 4: Fix the commercial terms
-
Packaging: bulk, jumbo bags or 25 kg and 50 kg bags, pallet wrapping and moisture protection.
-
Quantity and timing: trial quantity, regular volume and delivery window; for bulk, the unloading and storage arrangements. See bulk soda ash transport and caking prevention.
-
Delivery term: state the Incoterms 2020 term you want quoted so offers are comparable.
-
Import requirements: confirm with your customs broker which conformity and customs documents apply to your product in Saudi Arabia or the destination country before shipment.
Compare offers by landed cost per usable unit, including freight and trial cost, not by the ex-works figure alone.
Enquiry template
- Application and process (glass, detergent, water treatment or other).
- Type required (light, dense or open to recommendation).
- Impurity limits (iron, chloride) and particle-size or bulk-density needs.
- Required documents (TDS, SDS, COA, any declaration).
- Trial quantity and regular volume.
- Packaging, delivery place and Incoterms term.
Send it through the PLAXRAW quotation form. PLAXRAW reviews it and replies with the relevant questions or options; it does not promise stock, specifications or lead times before the details are confirmed.
