Key takeaways
- Give suppliers one accepted specification and delivery basis to quote.
- Distinguish a product request from a request for additional evidence.
- Confirm the physical supply arrangement and its applicable status.
- Keep alternative products separate until their acceptance is established.
Rotterdam's permit context defines a supplier check
Rotterdam publishes a bunker-permit application covering residual fuels, distillates and biodiesel supplied to seagoing vessels. Port of Rotterdam bunker permit
Use that context to identify the relevant physical supply arrangement and confirmation needed. It is not a reason to assume that the fuel buyer itself needs the supplier's permit, or that a permit answers every vessel-specific acceptance question.
For a current transaction, the scoped enquiry reference is not provided; obtain current verified information. Record the accepted product, quantity basis, delivery period, location and required commercial evidence. Keep unconfirmed alternatives visibly separate.
Write the product request before the price request
Use the specification and grade accepted by the responsible vessel or technical team. Preserve the edition and any additional purchase conditions rather than translating them into a shorter label that loses material detail.
If the buyer seeks both conventional fuel and a proposed bio-blend alternative, request separate complete offers. The alternative should state its actual product description and evidence scope; the word bio should not replace the accepted specification or a defined commercial claim.
Do not infer environmental treatment from the label. If a particular certification or reporting purpose matters to the purchase, identify the evidence the responsible compliance team requires and seek its review separately from the fuel-price comparison.
Define what quantity and price mean
State whether the quantity is a firm requirement or an estimate awaiting confirmation. Ask how permitted changes affect unit price, minimums and delivery inclusions. A supplier cannot provide a comparable proposition if one quote assumes a different parcel size.
Identify the currency and unit. If alternatives use different currencies or quantity bases, flag the need for a documented normalisation before ranking them. Do not conceal a conversion assumption inside an apparently direct price comparison.
Request all material separate charges and their triggers. A lower fuel price with an unresolved delivery component remains incomplete. Likewise, avoid adding a service allowance that is already included in a quoted delivered price.
A Rotterdam enquiry matrix
| Enquiry component | Detail to provide | Clarification to request |
|---|---|---|
| Accepted fuel | Specification, grade and purchase conditions | Exact conformity or proposed exception |
| Bio-blend alternative | Defined product and required evidence | Whether the offered evidence supports the intended review |
| Quantity | Grade-specific amount and status | Minimums, tolerances and revision basis |
| Delivery proposition | Intended location and period | Firmness, conditions and physical supply arrangement |
| Price | Unit, currency and service boundary | Separate or conditional charges |
| Confirmation | Decision deadline and responsible buyer | Outstanding acceptance or credit conditions |
The matrix makes a supplier's response easier to assess without asking it to infer the buyer's technical or reporting requirements.
Treat evidence as part of the quoted scope
A supplier may be able to offer a product while further documentation remains pending. Record that condition clearly. The buyer should not value an intended reporting benefit as confirmed merely because the fuel itself is available.
If obtaining additional evidence changes the commercial offer or timing, show that consequence. Do not assume every certificate is interchangeable or that a later document will necessarily support the buyer's intended use.
The relevant specialists should assess the evidence and the current applicable text. This article concerns the procurement question; it does not determine eligibility under an emissions scheme or advise on fuel use onboard.
Fictional case: one label hides two different enquiries
A fictional Rotterdam buyer sends an enquiry asking for a bio-blend at an attractive price. One supplier offers a defined physical product, while another includes a different documentation package and delivery period. The first spreadsheet ranks the unit prices as if the offers were identical.
The desk revises the enquiry using the accepted product description and the compliance team's specific evidence request. It obtains comparable responses and keeps any unsupported reporting assumption outside the economic comparison.
The resulting choice reflects the actual required purchase. The buyer has not assumed that a broad fuel label proves technical suitability or an environmental outcome.
Convert the enquiry into an intelligible confirmation
The order should preserve the selected product, evidence scope, quantity, delivery conditions and complete price boundary. Identify any outstanding condition rather than allowing it to disappear between quotation and confirmation.
If the supplier proposes a different product or period, assess the change explicitly. Check the current text and obtain appropriate review where the amendment affects rights or the stated purpose of the purchase.
Common mistakes
Do not compare different products simply because both use a broad low-carbon label. Other errors include omitting the specification edition, treating evidence as automatically included and assuming the supplier's permit establishes vessel suitability. A conditional documentation package should not be reported as a confirmed commercial benefit.

Frequently asked questions
Can conventional fuel and a bio-blend be quoted together?
Yes, but preserve separate product descriptions, evidence scope and acceptance status so the comparison remains clear.
Does a supplier permit approve the fuel for the vessel?
No. Obtain the relevant vessel-specific assessment for the proposed purchase.
Should reporting evidence be requested before price agreement?
Yes, when it is material to the purchase purpose. Define the required scope and have it reviewed.
What should the enquiry data slot contain?
Record the accepted product, quantity, delivery basis and evidence requirements, including unresolved conditions.
