BO-050
Base stock procurement profile
Re-refined neutral base oil enquiry requiring a named viscosity target and independent batch-quality review. API group must be confirmed, never inferred from recycled origin.
| Key buying criteria | Viscosity target, API group evidence, sulfur, saturates, VI, water, metals/contaminants, batch COA, process and feedstock traceability |
|---|---|
| Packing | Bulk, drums or IBCs subject to product compatibility, net mass, cleanliness and agreed transport requirements. |
| Documentation | TDS · SDS · COA · origin, traceability and agreed inspection |
Grade names are commercial enquiries, not universal specifications. SN/N/R numbers are refiner-specific; cSt must state temperature. ISO VG describes viscosity at 40°C. II+ and III+ are market labels. GTL is a process; re-refined is an origin. Confirm API group and compatibility from the actual TDS and batch COA. Base stocks are ingredients, not finished engine oils or API-licensed lubricants.
