Overview

The commercial opportunity may be attractive: a supplier offers another parcel, a customer changes its allocation or the trader wants to combine sales. The coordinator's task is to turn that request into a defined proposal that responsible parties can assess, while preserving the current authorised programme until a decision is made.

Key takeaways

  • Give the proposed additional grade a separate parcel and specification reference.
  • Identify effects on the existing cargo commitments as well as the new parcel.
  • Keep technical assessment, pricing and customer authority as separate decisions.
  • Obtain scoped responses rather than assuming broad-category equivalence.
  • Reconcile the final programme and instructions before closing the amendment.

Define the addition as a separate proposition

Record the requester, product description, quantity status, specification pack and intended receiving arrangement for the additional grade. State whether the proposal supplements or replaces part of the current programme.

Do not leave the relationship ambiguous. A second parcel that replaces existing quantity can create different commercial questions from one that increases the programme. The responsible parties need to know which case they are being asked to consider.

Identify the business objective. The trader may want to fulfil another sale, preserve a supplier allocation or improve a combined commercial result. That objective can guide the comparison without determining technical feasibility.

Keep the request labelled as proposed while it is under review. An updated spreadsheet should not become the only signal to outside parties that the programme has changed.

Map effects on both grades

The original cargo's decisions remain relevant. Ask whether the proposed addition affects its commercial commitments, programme assumptions or scoped review responses.

The coordinator should not decide how the products would be handled or whether they are technically compatible. Route the defined proposal and information packs to the responsible vessel, cargo and specialist reviewers.

Decision areaQuestion to askEvidence required
New grade identityWhat product and specification are proposed?Controlled cargo pack and responsible source
Existing gradeWhich earlier commitments could be affected?Scoped commercial and review responses
Quantity structureIs the addition extra or substitutive?Authorised nomination basis
Receiving programmeWhere does each parcel belong?Separate receiving references and confirmations
Freight scopeDoes the current offer cover the amendment?Revised terms or explicit continuity confirmation
Specialist reviewWhat information or assessment is needed?Responsible reviewer's request and decision
Instruction releaseWho can authorise the combined programme?Current authority and supersession process

The map should be specific enough that each owner knows what answer is expected. A broad request asking everyone whether the addition is fine is unlikely to produce a reliable decision trail.

Keep the commercial model aligned with the proposal

Create a separate scenario for the combined programme and retain the base case. Identify which revenues, costs and obligations change.

Do not assume that adding a parcel creates a proportional freight adjustment. Ask the offering party to state the revised basis or confirm what remains applicable. An internal allocation is not a substitute for that response.

Check that the sales model uses the same quantity and receiving assumptions as the transport scenario. If one team treats the new grade as replacing existing cargo while another treats it as additional, the combined result will not describe a coherent proposition.

Where an amount remains indicative, label it accordingly. A precise total can still depend on an unresolved commercial term or specialist response, and those dependencies should appear beside the model.

Separate the required decisions

A customer may agree to the additional sale while vessel review remains open. An owner may provide a revised price while a receiving confirmation is outstanding. Preserve these states separately.

For contractual questions, check the current agreement and obtain authorised commercial or legal review. The coordinator should not assume that a general flexibility provision covers the new grade without the relevant interpretation.

When a reviewer requests more information, identify its source and the decision it affects. Do not turn the request into either a rejection or an assumed administrative formality.

The commercial lead can then choose whether to continue developing the proposal, modify it or retain the base programme. The decision should be grounded in the actual open matters rather than pressure to make the additional sale work.

Fictional case: an addition is treated as unused space

A fictional clean-products trader is offered a second grade and asks the coordinator to add it to the current programme. The initial message describes the change as using available commercial room and assumes the existing offer will remain suitable.

The coordinator creates a separate parcel reference and obtains the new specification pack. It asks the owner for the commercial basis of the combined proposal and routes the product information to the responsible reviewers. It also checks whether the original receiver's commitment is affected by the revised programme.

The responses reveal that the price, receiving sequence and review status each need separate clarification. The trader compares the developed alternative with the base case before deciding whether the additional sale is worth pursuing.

The process does not infer technical availability from a commercial description. It turns an appealing idea into a proposal whose economics and dependencies can be reviewed.

Release the combined programme coherently

If the amendment is authorised, issue a current programme reference that identifies both grades and their respective information packs. The related commercial instructions should make clear which earlier directions are superseded.

Check customer-specific records as well as the shared programme. A correct combined list can coexist with an old quantity or destination in an individual buyer's instruction.

Preserve conditions attached to the approval or commercial agreement. If follow-up evidence remains due, assign it explicitly and identify whether it affects any later decision.

If the addition is not selected, close the exploratory requests through the agreed channels and confirm the base programme's current status. Do not assume that all parties automatically understand that the proposal has been withdrawn.

Review what the request revealed

After the decision, identify whether the team received the new product information early enough and whether its scenario clearly described addition versus substitution. Those are practical improvements for future enquiries.

Also review whether the base cargo's commitments were considered early or only after the new opportunity had gained momentum. A change process should protect the coherence of the whole programme rather than focus exclusively on the newest parcel.

Retain the evidence supporting the decision. If the additional sale later appears attractive in hindsight, the record should show which terms and responses were actually available when the business chose its course.

Common mistakes

Treating a second grade as automatically covered by a broad clean-product category can bypass the actual product and programme review.

Another mistake is to leave unclear whether the new parcel adds quantity or replaces existing cargo. The commercial and transport models may then evaluate different propositions.

Finally, avoid assuming a proportional price adjustment from an internal allocation. Obtain the offering party's scoped response for the amended programme.

Frequently asked questions

Does adding a grade always require a new offer?

Ask the authorised offering party whether the current basis applies and retain its response. Do not assume either continuity or amendment without checking the actual scope.

Who assesses technical compatibility?

The responsible vessel, cargo and specialist reviewers do so within their roles. The coordinator supplies the defined proposal and tracks their questions and scoped decisions.

Can the new sale be discussed before reviews finish?

Yes, with its provisional status and dependencies explicit. A commercial discussion should not be presented as authority to implement an unfinished programme change.

What closes the amendment?

A reconciled authorised programme, scoped responses, current instructions and assigned residual work provide the basis for closure. Adding another line to the cargo list is only the start.
