Sodium Tungstate Dihydrate Bulk Price 2026: Industrial Grade Specs
Global Market Trends for Industrial Grade Sodium Tungstate
The global demand for sodium tungstate dihydrate is expanding across sectors requiring high-performance inorganic salts, including fireproofing agents, textile dyeing, and catalytic synthesis. As a global manufacturer, Ningbo Inno Pharmchem Co., Ltd. monitors tungsten concentrate volatility and supply chain disruptions to ensure stable output. Procurement managers are increasingly prioritizing suppliers who can guarantee consistent stoichiometry and impurity profiles over spot-market pricing fluctuations. The tungstic acid sodium salt market is seeing a shift toward consolidated sourcing, where buyers seek partners capable of scaling from pilot batches to multi-tonne deliveries without compromising technical parameters. Inno Pharmchem addresses this by maintaining dedicated production lines for industrial grade sodium tungstate, ensuring that bulk orders meet the rigorous demands of downstream manufacturing processes.
Purity Grade Tiers and Technical Specifications for Sodium Tungstate Dihydrate Procurement
Procurement teams must align grade selection with application sensitivity. Inno Pharmchem supplies sodium tungstate dihydrate that serves as a direct drop-in replacement for competitor equivalents, including ACS reagent and Chemically Pure (CP) grades sourced from major laboratory chemical suppliers. Our manufacturing process controls critical impurities to match or exceed benchmark specifications, ensuring seamless integration into existing formulations. The following table outlines the technical alignment between Inno Pharmchem's industrial offerings and standard competitor benchmarks.
| Technical Parameter | Inno Pharmchem Industrial Grade | Competitor Equivalent (ACS/CP Benchmark) | Drop-in Compatibility |
|---|---|---|---|
| Assay (Na2WO4·2H2O) | ≥98.0% / ≥99.0% (Grade Dependent) | 99.0-101.0% (Biofargo) / ≥99% (Thermo) | Direct substitution for CP and ACS reagent applications |
| Molecular Weight | 329.85 g/mol | 329.85 g/mol | Identical stoichiometry |
| Solubility (Water, 20°C) | 730 g/L | 730 g/L | Matches dissolution kinetics |
| Chloride (Cl) | ≤0.005% | ≤0.005% | Meets stringent impurity limits |
| Heavy Metals (as Pb) | ≤0.001% | ≤0.001% | Compliant with industrial safety thresholds |
| Appearance | White crystalline powder | White to Yellow / Slightly Crystalline | Superior color stability in optical grades |
When evaluating specifications, procurement teams often need to distinguish between grades for cost optimization. Refer to our technical analysis on detailed comparison of analytical reagent versus technical grade sodium tungstate specifications for parameter breakdowns relevant to your application. For high-purity requirements, Inno Pharmchem offers grades suitable for laboratory reagent use, ensuring trace impurity control matches the expectations of research and development departments.
Mandatory COA Parameters and Quality Assurance Benchmarks for Bulk Orders
Quality assurance in bulk sodium tungstate procurement relies on batch-specific Certificate of Analysis (COA) verification. Inno Pharmchem provides comprehensive COAs detailing assay, insoluble matter, titrable free base, and critical impurity limits including chloride, sulfate, arsenic, and heavy metals. Our synthesis route is optimized to minimize transition metal carryover, which is essential for applications where catalytic activity or optical clarity is paramount. Procurement managers should request the COA for the specific batch number prior to shipment to validate compliance with internal quality benchmarks.
Field Engineering Note: Sodium tungstate dihydrate exhibits significant hygroscopic behavior. In high-humidity environments (>75% RH), bulk drums can experience surface moisture uptake leading to caking, which may be mistaken for degradation. Inno Pharmchem's manufacturing process controls residual moisture to prevent premature crystallization shifts. Procurement managers should verify that storage facilities maintain relative humidity below 60% to preserve free-flowing characteristics. Additionally, trace iron impurities, even at ppm levels, can induce yellowing in final formulations for optical coatings or high-clarity fireproofing agents. Our batch-specific COA includes iron content verification to ensure color neutrality in sensitive applications. Please refer to the batch-specific COA for exact impurity values per shipment.
Industrial Bulk Packaging Configurations and Supply Chain Logistics
Efficient logistics require robust packaging to maintain product integrity during transit. Inno Pharmchem offers sodium tungstate dihydrate in 25kg fiber drums with polyethylene liners and 250kg Intermediate Bulk Containers (IBC) for automated handling. Packaging configurations are selected based on order volume and destination handling capabilities. Shipping methods focus on secure palletization and moisture-barrier wrapping to protect against mechanical damage and environmental exposure during ocean or air freight.

Inno Pharmchem ensures timely dispatch and provides tracking documentation to support supply chain visibility.
Industrial Grade Sodium Tungstate Dihydrate Bulk Price 2026: Volume Tiers, Tariff Impacts, and Cost Drivers
Bulk pricing for disodium tungstate in 2026 is influenced by tungsten concentrate costs, volume commitments, and regional tariff structures. Inno Pharmchem provides competitive pricing models based on long-term supply agreements, with volume discounts applicable for orders exceeding 10 metric tonnes. Tariff impacts vary by destination; Inno Pharmchem offers Incoterms flexibility (FOB, CIF) to optimize landed costs for international buyers. Procurement teams should evaluate total cost of ownership, including supply chain reliability and technical support, rather than unit price alone. Contact our procurement specialists for a quote based on current market indices and your specific volume requirements.
