Product qualification
Specification points for kaolin purchasing.
Kaolin and calcined clay grades are normally qualified by brightness, particle size, residue, moisture, LOI and application fit. Exact figures should be confirmed by selected grade, TDS and COA.
Typical review items
Values below are presented as purchasing checkpoints rather than final guaranteed figures. Final indicators should be confirmed against the selected grade, TDS, SDS and COA.
| Product form | Hydrous kaolin and calcined kaolin grades selected by application route. |
|---|---|
| Brightness / whiteness | Confirmed by grade and COA; high-brightness options can be proposed for coatings, paper and ceramics. |
| Particle size | D50, top-cut and mesh profile confirmed by selected grade and end-use requirement. |
| 325 mesh residue | Controlled by grade; buyer target should be stated during enquiry. |
| Moisture and LOI | Reported on TDS or COA according to product form and shipment batch. |
| Typical applications | Coatings, ceramic bodies, paper filling and coating, rubber, plastics and construction products. |
| Packaging | 25 kg bags, palletised bags or jumbo bags depending on order and destination. |
| MOQ / trial order | Sample and trial order route available after application and target specification review. |
| Loading port / logistics | Export plan confirmed by origin, packaging, destination port and Incoterms. |

Commercial qualification notes for kaolin and calcined clay
Element keeps the original page framework while adding more buyer-facing detail for international procurement teams. The notes below are intended to guide early screening before the exact grade, TDS, SDS and COA package is confirmed.
| Relevant mineral route | hydrous kaolin, calcined kaolin and kaolin-based mineral grades. |
|---|---|
| Buyer performance questions | Target application, required whiteness or colour profile, particle size range, dispersion behaviour, moisture tolerance, formulation constraints and annual demand. |
| Specification checkpoints | Typical review points include brightness or whiteness, particle size distribution, residue, moisture, LOI, pH, oil absorption, bulk density and application-specific purity requirements. |
| Application fit | Common review areas include coatings, ceramics, polymers, paper, rubber, construction materials and specialised mineral formulations, depending on the grade selected. |
| Packaging route | 25 kg bags, jumbo bags and bulk shipment routes can be reviewed according to trial order size, destination port and handling requirements. |
| Documents available | TDS, SDS, COA, packing list, commercial invoice and third-party test documents can be aligned during buyer qualification. |
| Sample and trial route | Samples are best prepared after the buyer shares target specification, application field, destination country and preferred documentation format. |
Supply review
Confirm packaging, shipment rhythm, port preference and documentation before moving from sample to recurring supply.
Technical review
Use TDS, SDS, COA and trial feedback to narrow the final grade and avoid unsuitable substitutions.
