Gilsonite Specifications & Grades

Gilsonite specifications define the agreed quality limits for a commercial grade. Asia Gilsonite supplies natural asphaltite in different ash and particle-size options for drilling, asphalt and other industrial uses. Buyers should select a grade by application, ash content, moisture, mesh and any required thermal or compatibility parameters.

A specification is different from a batch analysis: the specification defines acceptance limits, while an analysis reports measured results. See our Gilsonite analysis page for that distinction and our Gilsonite properties page for technical background.

Gilsonite lump and powder specifications

Gilsonite lump and ground powder are forms of the same natural material, but they require different size and handling specifications. For a lump order, state the required lump-size range, acceptable fines, ash and moisture limits, packing, quantity and destination. For powder, specify the target mesh or particle-size distribution in addition to the quality limits. See the Gilsonite powder and mesh guide for the processed form. The downloadable ash-grade sheets below provide a starting point; confirm the agreed limits and batch analysis for each order.

For commercial purchasing, review the bulk Gilsonite buying guide and the Gilsonite price factors. For a complete introduction to export-grade Gilsonite, its industrial applications and supply capabilities, visit the Asia Gilsonite homepage.

How We Control Gilsonite Grade Quality

  • Selection of raw Gilsonite according to the target grade.
  • Controlled crushing, milling and screening for required particle size.
  • Drying capability when moisture control is required by weather or specification.
  • Covered storage to protect finished material before shipment.
  • Industrial bagging and export packing according to the agreed order.
  • Quality-control testing against ash, moisture, mesh and other agreed parameters before loading.
  • Buyer or independent inspection can be arranged when required before shipment.

For powder and mesh information, see Gilsonite powder. For handling and safety, use the Gilsonite SDS / MSDS.

Laboratory limits become useful only when they are matched to the formulation and process. Compare the available grades with our industrial Gilsonite applications, including Gilsonite for drilling fluids and Gilsonite for asphalt. Asia Gilsonite can then prepare the selected grade for bulk export through our Gilsonite supplier and exporter page.
