Buying sodium lignosulfonate powder starts with the application and required performance—not with a generic purity figure or the lowest price per tonne. Commercial grades can differ in moisture, pH, reducing sugars, inorganic content, water insolubles, molecular distribution, bulk density and application response. A useful quotation therefore needs a defined grade, specification, quantity, packaging and destination.
LigninCorp supplies industrial sodium lignosulfonate grades for evaluated applications. Feed-grade or animal-nutrition enquiries should be directed to the group’s Animal Nutrition division; agricultural formulation enquiries should follow the relevant Agriculture Solutions route. This page covers industrial powder procurement.
Select the grade by primary function
| Industrial requirement | Recommended starting page | Qualification focus |
|---|---|---|
| Cement dispersion or set-control screening | Construction Grade | Cement compatibility, workability, air, setting and strength. |
| Mineral, ceramic or pigment dispersion | Dispersant Grade | Viscosity, settling, foam, colour and electrolyte compatibility. |
| Pellet, briquette or granule binding | Binder Grade | Green strength, dry strength, abrasion, moisture and throughput. |
| Surface particle binding for dust control | Dust Control Grade Powder | Dilution, substrate, application equipment, climate and reapplication interval. |
| Specialty performance or lower use level | Super Grade | Application-specific comparison against the standard grade. |
The grade names identify a commercial starting point; they do not guarantee suitability in every formulation. Use the supplier dosage only as a recommended trial range and confirm performance with the customer’s raw materials and test method.
Specifications to define before requesting a quotation
State which parameters are purchase requirements and which are informational. Depending on the application, the agreed specification may cover:
- appearance and physical form;
- moisture or dry matter under a stated method;
- pH at a defined concentration and temperature;
- water-insoluble matter;
- reducing sugars or related process components;
- ash, sulfate or other inorganic content where relevant;
- bulk density and particle-size requirements for handling;
- application-specific dispersion, binding or cement test results.
A universal “purity” percentage is often ambiguous for a heterogeneous lignosulfonate product. Ask how the value is defined and measured. Compare offers only when the test methods and reporting basis are equivalent.
Documents to request
- TDS: product description, typical characteristics, application notes and storage guidance.
- SDS: current classification, handling, exposure control, transport and disposal information.
- Representative COA: an example of batch parameters before ordering.
- Batch COA: results associated with the supplied lot.
- Regulatory or origin documents: only those required for the destination and intended use.
Do not assume that an industrial grade has feed, food, pharmaceutical, cosmetic, organic-input or other regulated-use approval. Specify the market and end use so the correct documentation route can be confirmed.
Packaging and logistics
Packaging options depend on the grade, plant and order size. Request confirmation of bag construction, net weight, palletisation, container loading, labels and moisture protection in the quotation. For hygroscopic powders, keep packages sealed and store them in a dry, ventilated area according to the current TDS and SDS.
Delivered cost depends on grade, order quantity, packaging, Incoterm, origin, destination, freight conditions and documentation. Static internet price ranges quickly become misleading. For current commercial terms, request a dated quotation with a defined validity period rather than treating an indicative price as an offer.
Sample and qualification workflow
- Provide the intended application and target performance.
- Share the current product specification or benchmark, if available.
- Confirm whether comparisons will be made on as-supplied or dry-solids basis.
- Test the sample against an untreated control and current supplier grade.
- Record both processing behaviour and final-product properties.
- Approve the specification and documentation before a commercial order.
- Confirm the first production lot against the agreed incoming-inspection plan.
