Sodium Metasilicate Granules
Our primary export grade. Uniform granules with consistent dissolution and stable color for detergent builders and industrial formulations.
Product Overview
Sodium metasilicate granules are our main production line and export product. We supply uniform, free-flowing granules suitable for automated dosing in detergent manufacturing and industrial chemical blending.
Production is controlled in-house from raw material intake through granulation, drying, and packaging. Batch records support traceability for export buyers requiring consistent specifications.
Granule form reduces dust handling issues compared to powder grades and supports stable feeding in bulk blending operations.

Quick Inquiry
Why Global Buyers Source Granules 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 |
