TDS for technical screening
The TDS helps buyers decide whether a grade appears suitable for their project or asphalt plant before asking for a firm offer.
A Technical Data Sheet is one of the most important documents in a bitumen buying process. It helps the buyer understand the grade, typical properties, applications and handling notes before moving to commercial terms.
A Certificate of Analysis is different: it confirms the actual test values for a shipment or batch. Serious buyers should review both documents whenever possible.
The TDS helps buyers decide whether a grade appears suitable for their project or asphalt plant before asking for a firm offer.
The COA should be reviewed before shipment acceptance because it shows the final tested product values.
When buyers ask for documents early, the commercial discussion becomes more professional and less ambiguous.
Buyers often confuse these documents. The table below explains the difference.
| Document | Purpose | When to review | Buyer benefit |
|---|---|---|---|
| Technical Data Sheet | Describes typical product properties and application guidance | Before commercial confirmation | Helps screen the grade |
| Certificate of Analysis | Shows actual tested values for a shipment or batch | Before shipment acceptance/loading | Confirms quality values |
| MSDS/SDS | Provides safety and handling information | When required by buyer or destination | Supports safe storage and handling |
| Packing list | Shows packing details and cargo count | Before shipment documents are finalized | Supports customs and receiving |
| Bill of lading draft | Shows shipment route and cargo description | Before final shipping documents | Reduces document errors |
