Sodium Metasilicate Anhydrous
High-activity anhydrous grade for formulations requiring maximum alkalinity per unit weight and low moisture content.
Product Overview
Sodium metasilicate anhydrous provides the highest available alkalinity in the metasilicate product range. It is used where moisture introduction must be minimized in dry blend systems.
Our anhydrous line is produced on dedicated drying equipment with moisture control monitoring. Export packaging options support long-distance shipment to distributors and end manufacturers.

Why Global Buyers Source Anhydrous from China
Procurement teams choose Chinese manufacturers for bulk sodium metasilicate when factory-direct pricing, production scale, and export reliability outweigh regional sourcing premiums from EU or US distributors.
Price Advantage
Factory-direct supply from Shandong eliminates trader margins common in EU/US distribution channels. Bulk FCL orders achieve lower per-ton cost at equivalent purity specifications.
Production Scale
100,000+ tons annual capacity supports recurring volume contracts. Granule production is our highest-output line — suitable for detergent manufacturers with continuous demand.
Export Quality Stability
Batch-controlled SiO₂, Na₂O, iron content, and color consistency. COA issued per shipment. Specifications maintained across production runs for long-term supply agreements.

China vs Other Countries — Supply Comparison
Practical factors B2B buyers evaluate when comparing Chinese factory-direct supply against EU, US, or intermediary distributors.
| Factor | China Factory Direct | Trading Companies | Overseas Suppliers |
|---|---|---|---|
| Pricing | Factory-direct — no trader margin | Intermediary markup | Higher regional premiums |
| Production capacity | 100,000+ tons/year | No production control | Limited regional capacity |
| Bulk FCL supply | Standard MOQ ~20 MT | Same source, higher price | Higher per-ton cost |
| Specification control | In-house QC, batch COA | Depends on upstream | Premium for equivalent spec |
| Export documentation | COA, TDS, MSDS per shipment | Documentation fees common | Import documentation costs |
| Combined grade orders | Granules + anhydrous + pentahydrate + silicate | Often single-SKU | Limited grade range |
