Key takeaways

  • Preserve the link between the outgoing lot and the evidence describing it.
  • Label physical mass, volume and commercial quantity according to their purpose.
  • Identify who determines each figure under the actual arrangements.
  • Carry receiving allocation and permitted substitutions into the handover.
  • Reconcile differences without assuming every change represents a physical cargo loss.

Handover one parcel with several views

Different teams can legitimately view the same woodchip shipment through different quantities. Vessel interests need the physical cargo proposal. The commercial buyer may use another agreed basis to calculate payment. The receiver may maintain its own inventory or process-facing view.

The handover should connect those views without collapsing them into a single unexplained number. State the figure, unit, purpose, evidence and responsible party. If a quantity is provisional, identify the event or determination that will replace it.

This is especially important when a negotiation has moved through several parcel proposals. A superseded physical estimate may remain in an email while the recap reflects a revised commercial quantity. The operating team should receive the final supported relationship, not be expected to reconstruct it from the message history.

Do not imply that one internal reconciliation overrides the actual contracts. Different documents may serve different agreed purposes. Where their relationship is unclear, obtain the relevant commercial or qualified contractual clarification before relying on a particular figure.

Keep the outgoing lot attached to its evidence

Identify which material is intended to load, including any lots that the commercial plan requires to remain distinguishable. The evidence supplied for cargo review should be traceable to that material.

If the final allocation differs from the parcel described during negotiations, make the change explicit. Ask the parties whose assessments depended on the original information whether their conclusions still apply. A substitution can affect the receiver's purchase requirement and the vessel's cargo review in different ways.

The handover should state which substitutions are permitted under the actual arrangements and which require a fresh decision. Do not create a broad substitution right merely to simplify operations. Equally, do not describe a supported alternative as prohibited without checking the terms.

The practical objective is continuity: the team executing the movement should understand what was offered, what was accepted and what is now intended to be loaded.

Assign the quantity questions by role

The following map is a set of questions for the actual parties. It does not prescribe default contractual responsibilities.

RoleQuestion to settleHandover output
ShipperWhat material is allocated and what evidence describes it?Identified outgoing lot and supported cargo information
Vessel interestsWhat physical parcel does the voyage proposal cover?Current intake and arrangement basis, with conditions
Measuring or testing partyWhat determination is being made and for which purpose?Defined scope, method reference and reporting basis
BuyerWhich quantity basis governs the commercial comparison?Agreed payment basis and unresolved interpretation points
ReceiverHow will the arriving allocation enter its programme?Accepted destination and relevant receiving requirements
Operations coordinatorWhich figures must remain connected during execution?A concise reconciliation map and named decision owners

Where an organisation performs several functions, keep the questions distinct. The same company can issue a logistics update and a commercial settlement instruction without those messages having the same purpose.

Fictional case: three quantities, no immediate contradiction

A fictional woodchip shipment is handed over with a physical cargo estimate, a commercial dry-basis purchase quantity and a receiver's provisional inventory entry. The operating team notices that the figures differ and initially treats the differences as an unexplained shortage.

The coordinator first labels the figures. They do not all measure the same thing at the same stage. The physical estimate describes the material proposed for loading. The purchase figure uses the agreed commercial basis. The receiver's entry is provisional pending its own applicable process.

The team then asks whether the figures reconcile using the supported inputs and the actual agreements. It does not assume they must be identical, but it also does not dismiss an unexplained difference merely because multiple bases exist.

One outdated estimate is removed from the current handover. The remaining figures retain their separate labels and purposes. A genuine unresolved commercial question is sent to the responsible buyer and seller rather than being buried in the operations log.

The improvement is a disciplined sequence: define the basis, connect the evidence, then assess any remaining discrepancy. That is more useful than declaring a loss before determining what the numbers represent.

Separate a measurement difference from a commercial dispute

A difference between two figures can arise because they refer to different units, stages, parcels or determinations. Start by checking those boundaries. If they differ, explain the relationship before calculating a variance.

Where the figures do purport to represent the same quantity, identify the relevant evidence and agreed determination process. The chartering desk should not choose whichever result is commercially convenient. Nor should it assume that a later document automatically replaces every earlier figure for every purpose.

A physical discrepancy, a pricing adjustment and a document inconsistency require different responses. Keeping those categories separate helps the business ask the right party the right question. It also prevents a routine unit reconciliation from being presented as a claim without support.

Any determination of contractual rights belongs in a separate qualified review of the current agreed terms and evidence. The handover map supports that review but does not decide it.

Carry the receiving allocation through execution

The receiver needs to know which arriving material belongs to which commercial allocation. If the programme contains several customers or lots, show the intended allocation and the restrictions that the actual agreements impose.

Do not assume the operator may redirect material simply because a destination is physically available. A proposed change can alter the buyer's commercial purpose or the receiver's acceptance. Obtain the relevant decision before treating the alternative allocation as part of the operating plan.

The same discipline applies to a partial delivery. Identify what has been received, what remains outstanding and which quantity basis each statement uses. A progress update should not convert a provisional operational figure into a final settlement determination without support.

Make the closeout useful to the next shipment

At closeout, retain the final parcel identity, the determinations used for their respective purposes and the explanation of material differences. This allows the next enquiry to use actual experience without copying an unexplained historical number.

Distinguish a parcel-specific observation from a general planning assumption. A result from one shipment may be useful context, but a future parcel still needs its own supported description. The lesson to preserve is often which information was missing or mislabeled, rather than a single conversion factor to reuse indefinitely.

Common mistakes

A common mistake is handing over only the commercial purchase quantity while leaving the physical shipment basis unclear. Another is assuming every difference between documents represents missing cargo.

A third error is allowing an old parcel estimate to survive beside the revised allocation without explanation. Finally, do not resolve a genuine quantity dispute by selecting a preferred figure outside the agreed determination process.

Frequently asked questions

Should every document show the same woodchip quantity?

Not necessarily. Documents may use different agreed bases or serve different purposes. Their relationship should be explicit, and unexplained discrepancies still need investigation.

Who should reconcile the figures?

A named coordinator can assemble the comparison, while the responsible cargo, measurement and commercial parties confirm their respective inputs. The coordinator should not invent a final determination.

Does a dry-basis figure describe the physical load?

It serves a distinct quantity purpose. Keep the actual physical shipment information visible and explain the supported relationship rather than treating the two figures as interchangeable.

What if the source material changes after fixing?

Identify which prior information and acceptances depend on the original parcel. Ask the relevant parties to assess the changed proposal before relying on the earlier conclusions.

What belongs in the final handover summary?

The outgoing lot, current physical proposal, commercial quantity basis, receiving allocation and unresolved decisions. Each important figure should have a purpose, evidence and responsible party attached.
