Quality is a document trail, not a slogan
For industrial fluorspar, quality should be evaluated through measurable fields: CaF2, SiO2, CaCO3, sulfur, phosphorus, moisture, particle size, and lot identity. A useful quotation should state which document controls the final release basis.
- COA line items and test method basis.
- Sampling point and whether the result is tied to the shipped lot.
- Moisture basis for wet or dried powder.
- Packing condition, bag type, loading method, and destination handling requirements.
