Product Composition and Purchasing Specification
A well-defined specification gives procurement, technical and quality teams a shared basis for evaluating the proposed supply.
For n-pentane/isopentane 80/20, please identify both the nominal composition and the acceptable range for each component. Confirm whether the ratio is expressed by weight or by volume rather than relying on the product name alone.
Your specification may also include requirements for:
- Other components and impurities.
- Water content.
- Sulfur content.
- Test methods and reporting units.
- Quality acceptance criteria.
- Technical and safety documentation.
Our team can review these requirements and confirm the proposed specification and available supporting documents before order confirmation.
For ongoing purchases, the approved specification can be referenced in each order. This establishes a clear framework for repeat supply and allows any requested changes to be discussed before the next shipment.
Bulk Orders: 14 MT per ISO Tank
The loading quantity for this supply arrangement is 14 metric tonnes per ISO tank.
Please state both the total tonnage and the number of tanks required when submitting an inquiry. This helps define the order clearly and supports the review of shipment options.
| Number of ISO tanks | Total product quantity |
|---|
| 1 | 14 MT |
| 2 | 28 MT |
| 3 | 42 MT |
| 4 | 56 MT |
For recurring demand, include your estimated monthly consumption and preferred shipment frequency. Our team can then discuss the proposed order size and schedule against your purchasing requirements.
Receiving-site arrangements should also be considered during planning. Please share any relevant unloading requirements and the time needed to receive and discharge the tanks so these details can be addressed in the commercial review.
