| Product identity |
Is the product sodium bentonite, calcium bentonite, activated bentonite, micronized bentonite, granular bentonite, or a formulated binder blend? |
Prevents confusion between different clay types and commercial preparations. |
| Intended function |
Is the grade designed for pellet binding, carrier use, anti-caking, moisture control, mycotoxin binding, or multi-purpose use? |
Ensures the product matches the buyer’s manufacturing objective. |
| Mineralogical profile |
What are the levels of montmorillonite, smectite, quartz, feldspar, calcite, kaolinite, illite, or other minerals? |
Mineralogy influences swelling, binding behavior, safety review, and product consistency. |
| Montmorillonite / smectite content |
Is the active clay fraction declared or supported by analysis? |
Often central to clay characterization and product comparison. |
| Cation type |
Is the product sodium-dominant, calcium-dominant, or activated? |
Influences swelling, water absorption, dispersion, and handling behavior. |
| Swelling capacity |
What is the swelling index or swelling volume? |
Useful for characterizing water interaction and binding potential. |
| Cation exchange capacity |
Is CEC declared, and which method is used? |
Useful for clay-mineral characterization and supplier comparison. |
| Particle size |
Is the particle-size distribution suitable for premix, pellet, aquafeed, or powder-blend production? |
Supports uniform distribution, dosing accuracy, dust control, and process performance. |
| Bulk density |
What is the typical loose and tapped bulk density? |
Useful for dosing equipment, packaging volume, silo handling, and logistics. |
| Moisture |
What is the moisture limit? |
Influences flowability, caking, microbial risk, shipment weight, and storage behavior. |
| Dust level |
Is the product fine powder, low-dust granule, or compacted product? |
Important for worker handling, factory housekeeping, and dosing systems. |
| Flowability |
Does the product bridge, cake, segregate, or flow consistently? |
Important for micro-dosing, premix, bagging, and automated feed systems. |
| Pellet performance |
Does the supplier provide pellet durability, fines reduction, hardness, or water-stability support data? |
Directly linked to the intended binder function. |
| Nutrient dilution |
What inclusion rate is required to achieve the target effect? |
Binder inclusion can affect nutrient density, formula cost, and feed labeling. |
| Compatibility with actives |
Is it compatible with enzymes, probiotics, vitamins, minerals, medications, pigments, acids, and flavors? |
Important because carriers and clays can interact with sensitive additives. |
| pH in suspension |
What is the pH profile in water suspension? |
Relevant for product characterization and compatibility review. |
| Heavy metals |
Are lead, arsenic, cadmium, mercury, and other elements controlled? |
Natural minerals must be checked carefully for feed safety and import compliance. |
| Dioxins and PCBs |
Are dioxin, dioxin-like PCB, and non-dioxin-like PCB declarations available when required? |
Important for mineral feed additives and export-market compliance. |
| Crystalline silica / quartz |
Is quartz or respirable crystalline silica level declared where required? |
Relevant for worker-safety review and dust exposure management. |
| Microbiological status |
Are total plate count, yeast, mold, Salmonella, and other parameters declared? |
Important for feed-safety systems, premix producers, and export buyers. |
| Packaging |
Is the product supplied in 20 kg, 25 kg, big bags, bulk, lined bags, or palletized format? |
Impacts storage, moisture control, handling, and shipment planning. |
| Shelf-life |
What is the expiry or retest period under recommended storage? |
Needed for stock planning, distributor resale, and quality control. |
| Country of origin |
Where is the product mined and processed? |
Often required for import clearance, customer approval, and traceability. |
