| Whole-material Chaga powder | Dried Chaga material milled into powder; the raw-material identity and preparation should be specified. | Tea-style drinks and ingredient blending. | Species identification, raw-material origin, moisture, particle size, and contaminant testing. |
| Coarse-cut Chaga | Dried pieces or coarse granules rather than a fine-milled powder. | Decoctions and steeped beverage preparations. | Cut size, foreign-matter limits, drying method, and batch traceability. |
| Hot-water extract powder | Water-extracted material concentrated and dried; extraction conditions and carrier use can vary. | Instant drink mixes and supplement formulations. | Extraction solvent, extract ratio definition, carriers, and analytical methods behind any stated values. |
| Water-soluble extract powder | An extract processed for dispersion or dissolution in water; solubility should be tested under stated conditions. | Powdered beverages and ready-to-mix formulations. | Solubility test method, sediment information, moisture, and formulation aids. |
| Dual-extract powder | Generally made using both water and an alcohol-based extraction step; the exact process differs among products. | Capsules, powders, and other supplement formats. | Extraction sequence, residual-solvent testing where applicable, and full composition details. |
| Polysaccharide-characterized extract | An extract accompanied by a polysaccharide assay; results depend on the analytical method and are not interchangeable across methods. | Supplement and functional-food ingredient development. | Test method, batch-specific certificate of analysis, and whether the result refers to total polysaccharides or a defined fraction. |
| Triterpenoid-characterized extract | An extract characterized for selected triterpenoid compounds when suitable validated testing is available. | Research and specialized ingredient formulation. | Named analytes, reference standards, test method, and batch-specific analytical results. |
| Capsule-grade powder or extract | A powder supplied with handling and particle characteristics suitable for capsule filling; excipients may be present. | Capsule and tablet manufacturing. | Bulk density, flow properties, excipient disclosure, and microbiological specifications. |
| Beverage-grade ingredient | Powder or extract selected for incorporation into a beverage; taste, dispersibility, and formulation compatibility require testing. | Tea blends, powdered drinks, and beverage premixes. | Sensory sample, solubility or suspension behavior, stability, and applicable food regulations. |
| Bulk formulation ingredient | A bulk powder or extract supplied for further processing; the final product category depends on the finished formulation and local rules. | Food, beverage, or supplement product development where legally permitted. | Manufacturing controls, traceability, certificate of analysis, heavy metals, pesticides, microbes, and destination-market compliance. |
