Key takeaways
- Distinguish vessel-related charges from operator licensing entries.
- Ask whether the supplier includes or excludes each relevant component.
- Reconcile the agent estimate against the same delivery proposition.
- Use current applicable terms without inventing a standard all-in allowance.
Read Gibraltar's tariff categories separately
Gibraltar Port Authority's tariff page distinguishes bunkering charges from fees relating to operator licences and certificates. GPA port tariffs
The presence of an entry on that page does not mean every buyer should add it directly to every vessel call. Check the current text, applicable category and agreed payer with the responsible parties before incorporating an amount.
For a current transaction, the tariff-inclusion reconciliation is not provided; obtain current verified information. Record the relevant current charge references, supplier and agent inclusions, agreed payer and unresolved components. No prevailing fee amount is assumed here.
Start with a common delivery proposition
Both supplier offers should cover the same accepted fuel, quantity, delivery mode and intended period. A tariff comparison cannot repair a mismatch between an anchor supply and another proposition with different service consequences.
Identify which party provides each cost estimate. The supplier may describe a delivered fuel price while the agent estimates wider call services. Their scopes can overlap without either document being wrong.
Ask for clarification at the component level. A general assurance that the quote is all-in is less useful than identifying which relevant costs are included and which remain payable elsewhere.
Avoid treating the tariff as a shopping list
Read the purpose of each category before adding it to the estimate. An operator licence fee and a charge related to a vessel taking fuel describe different contexts. The buyer should not assume that every visible administrative fee is its own direct liability.
Where the agreement passes through a particular cost, identify the basis and supporting evidence. Do not infer a pass-through solely because a public tariff exists.
Keep fixed, quantity-dependent and conditional amounts separate. This makes it easier to update the model when the required quantity changes or a condition is not triggered.
A fictional duplicated inclusion
The following example uses invented amounts and assumes the parties have confirmed the stated inclusions. It does not reproduce a Gibraltar tariff rate.
ILLUSTRATIVE: A supplier's delivered quotation totals $186,000 and expressly includes a defined $2,000 call-related component. The agent estimate totals $3,000, comprising that same $2,000 component plus $1,000 of other services.
Adding both headline totals gives $189,000 and counts the shared component twice. The reconciled included amount is $187,000: $186,000 plus the separate $1,000.
The overstatement is $2,000. This correction is valid only because the parties confirm that the two references describe the same charge and that it is already included in the supplier amount.
Similar labels alone are insufficient. Two charges with comparable names may cover different scopes, so the reconciliation needs evidence rather than an automatic deduction.
Build an inclusion map
| Component | Supplier treatment | Agent or other treatment | Required conclusion |
|---|---|---|---|
| Fuel amount | Unit price and quantity basis | Normally not the same purchase line | Confirm the accepted fuel calculation |
| Identified call charge | Included, excluded or conditional | Check whether also estimated | Establish one supported treatment |
| Separate agency service | Identify any relevant inclusion | Scope and quoted amount | Avoid assuming it is part of the fuel price |
| Operator-related fee | Clarify any claimed contractual pass-through | Do not presume direct vessel liability | Obtain the actual basis and payer |
| Conditional expense | Trigger and calculation | Check overlapping allowances | Include only according to the stated scenario |
The final comparison should explain differences between offers, not merely produce a lower total by deleting unfamiliar lines.
Fictional case: two all-in descriptions overlap
A fictional buyer receives a Gibraltar fuel offer described as delivered and an agent estimate described as the full call account. The initial worksheet adds both totals and rejects the purchase against another location.
The desk asks each party to identify its scope and finds one explicitly shared component. After confirming that it is included in the supplier's amount, the buyer removes the duplicate from the combined comparison while retaining the genuinely separate agency services.
The resulting total is lower for a supported reason. The desk does not delete other lines simply because they also sound related to the call.
Preserve the reconciliation through payment
The purchase confirmation and agent instruction should reflect the agreed inclusion map. If the final invoice presents a component separately, compare it with the confirmed arrangement before assuming it is an additional amount.
Retain the relevant tariff date and source reference where a public rate is used. A later update should not silently replace the basis used for an earlier comparison without an applicability review.
Check the current text and obtain appropriate review where payer responsibility or a pass-through is uncertain. The model should identify the question without deciding legal liability from a heading.
Common mistakes
Do not add every tariff entry to the vessel estimate or count an included component twice. Other errors include deleting similarly named charges without evidence, ignoring conditional triggers and treating an all-in label as a complete explanation. The correct comparison depends on scope, applicability and agreed responsibility.

Frequently asked questions
Does every tariff fee apply to the fuel buyer?
No such assumption should be made. Establish the applicable category, payer and contractual basis.
Can two similar charge names be netted automatically?
No. Confirm that they refer to the same component and identify where it is included.
Should agent and supplier totals always be added?
Reconcile their scopes first, then combine only the supported non-duplicated amounts.
Does the example use current Gibraltar charges?
No. The amounts are fictional and demonstrate an inclusion error.
