Key takeaways
- Verify the quoted supply chain and relevant licensing status.
- Compare the same grade, quantity tolerance and delivery proposition.
- Add separate delivery charges without duplicating included services.
- Keep credit, validity and delivery conditions beside the price.
Begin with Singapore's provider framework
MPA publishes lists of licensed bunker suppliers and bunker craft operators for Singapore. MPA bunkering service providers
Use the relevant current list to check the entity performing the stated role. A familiar trading name should not obscure which party sells the fuel, which party supplies it physically and whose documents support the delivery. Licensing status does not settle every commercial or vessel-specific acceptance question.
For a current transaction, the provider verification reference for this enquiry is not provided; obtain current verified information. Record the source date and exact legal entity, rather than a general statement that the supplier is known locally.
Align the purchase before comparing prices
A VLSFO quotation and a marine gas oil quotation are not alternative prices for the same purchase. Compare each requested grade against its own accepted specification and quantity, then combine the complete package where appropriate.
Even two offers using the same grade label may describe different specification editions or additional limits. Send unresolved differences to the responsible technical reviewer. Do not resolve them by assuming the lower-priced description is equivalent.
Check the nominated quantity, permitted variation and the quantity to which any minimum charge applies. An offer suitable for a larger parcel may lose its apparent price advantage on the smaller quantity the vessel actually requires.
The delivery window also belongs in the comparison. A quote for a different day or location needs an explicit assessment of its call consequences before it can be ranked alongside the requested proposition.
Calculate the complete quoted amount
The example below isolates purchase and stated delivery charges. It assumes both fictional offers satisfy the same accepted specification and delivery conditions; it is not a current Singapore quotation.
ILLUSTRATIVE: For 400 tonnes, Offer A quotes $620 per tonne plus a separate $8,000 delivery charge. Its complete included amount is $256,000: 400 × $620 + $8,000.
Offer B quotes $635 per tonne with the same delivery service included. Its amount is $254,000, making it $2,000 lower for this defined purchase despite the higher unit price.
The unit-price difference is $15 per tonne. Dividing the $8,000 separate charge by $15 gives a crossover quantity of approximately 533.33 tonnes. At 600 tonnes, Offer A totals $380,000 and Offer B $381,000, so their ranking reverses under the same assumptions.
This crossover applies only while the quoted charge structure and conditions remain unchanged. A different parcel may attract another quotation, and the vessel should not order an unnecessary quantity merely to move across an arithmetic threshold.
Use a comparison matrix that exposes conditions
| Component | Offer comparison | Action before selection |
|---|---|---|
| Product | Exact grade and accepted specification | Resolve material differences with the responsible reviewer |
| Quantity | Required amount, tolerance and minimum charging basis | Calculate against the actual requirement |
| Delivery | Location, window and service inclusions | Confirm the proposition fits the call |
| Additional charges | Fixed, variable and conditional amounts | Obtain the trigger and calculation basis |
| Payment | Due date, currency and credit terms | Assess cash requirements on consistent dates |
| Validity | Expiry and remaining conditions | Ensure the compared offers are simultaneously usable |
An unresolved component should remain visible. Marking it as zero simply because the quotation is silent understates the uncertainty in the total.
Distinguish a quoted inclusion from an assumption
Ask whether the stated price includes the identified delivery service and whether extra waiting or revised timing can create a charge. The purpose is to establish the commercial boundary, not to invent standard local fees.
If a supplier gives a revised total, determine whether it replaces the earlier quotation or adds to it. Keep the price bridge clear enough that the buyer can identify the effect of quantity, timing and scope separately.
Credit terms can also affect the usable choice. Compare the timing and conditions of payment rather than treating a deferred-payment price and an immediate-payment price as identical cash propositions. Any funding calculation should use the buyer's stated assumptions and appropriate review.
Fictional case: the supplier rank changes with quantity
A fictional operator receives two acceptable Singapore offers for its nominated fuel grade. The first has a lower unit price but a separate delivery charge; the second includes delivery. The initial spreadsheet ranks them by unit price alone.
The vessel's confirmed requirement is lower than the preliminary enquiry quantity. The buyer recalculates both complete totals using that requirement and discovers that the second offer now provides the lower included amount.
Before ordering, the desk checks that the revised quantity and delivery period remain covered by both quotations. It selects from the offers actually available, rather than relying on an earlier quantity comparison or extending an expired price.
Common mistakes
Comparing unlike grades or delivery periods creates a misleading ranking. Other errors include adding a charge already included, assuming silence means no charge, and ignoring minimum quantities. A current provider-list check supports due diligence but does not prove that the fuel or delivery proposition meets the vessel's requirements.

Frequently asked questions
Is the lower per-tonne quote always better?
No. Fixed charges and conditions can reverse the complete-cost ranking at the required quantity.
Should an unspecified charge be entered as zero?
No. Obtain clarification or keep it explicitly unresolved.
Does the crossover quantity recommend buying more fuel?
No. It explains the price structure. The vessel's appropriately confirmed requirement remains the purchase basis.
What if one quote expires before the other arrives?
Refresh the comparison. An expired price is background information, not an available alternative.
