Key takeaways
- Identify the actual methanol specification proposed in the purchase.
- Obtain the responsible team's acceptance for the intended vessel and use.
- Keep product quality, environmental attributes and delivery availability separate.
- Compare costs on a supported quantity and pricing basis.
Historical supply is context, not a standing offer

Neither reference confirms this vessel's technical acceptance, current product stock or service window. Check the current relevant standard and applicable arrangements with the responsible reviewers.
For a current transaction, the methanol purchase basis is not provided; obtain current verified information. Record the accepted specification, quantity basis, evidence requirements and outstanding supply conditions.
Put the specification into the actual enquiry
The technical team should provide the fuel requirement that procurement is authorised to seek. The supplier should respond to that requirement rather than merely offering methanol under a broad commercial label.
Identify the referenced standard and edition, together with any expressly accepted additional conditions. If the supplier proposes a different basis, state the deviation and obtain the relevant assessment before treating the offer as equivalent.
A standard's existence does not automatically incorporate it into the parties' agreement. The accepted order should make the intended specification basis clear, with interpretation reviewed appropriately where necessary.
Distinguish product conformity from vessel acceptance
A supplier's statement about its product and the vessel team's acceptance answer related but different questions. Procurement should preserve both rather than describing the fuel as universally suitable because it cites a recognised specification.
The responsible reviewers may need product evidence connected to the actual proposed parcel and intended use. Provide the relevant documents and record the scope of their conclusion.
Do not infer acceptance from another vessel's historical delivery. That earlier event involved its own product, arrangements and assessment, none of which substitutes for this purchase's requirements.
Keep environmental attributes outside the quality shorthand
If an offer includes a production-origin or environmental description, identify exactly what evidence and quantity it covers. The specification review should not silently convert that description into a verified reporting benefit.
Conversely, evidence supporting a claimed attribute should not replace the accepted product-quality basis. A buyer may need both, depending on the commercial purpose of the purchase.
Where the claimed benefit affects regulatory reporting or value, obtain qualified review of the current applicable framework. Procurement should state what has been assessed and what remains conditional.
Understand the quantity and price unit
The offer should identify the quantity being sold and the unit used for billing. If the buyer compares an energy-based proposal with a mass-based one, use only a supported conversion basis accepted for that purpose.
A cost-per-energy calculation does not, by itself, establish the vessel's resulting consumption, operating efficiency or substitution quantity. Those require appropriate technical assessment and should not be invented to make the quote comparison convenient.
Keep service charges and other agreed costs visible alongside the fuel amount. A specification-compliant product is not a complete delivered proposition if its local delivery remains unconfirmed.
A methanol purchase review matrix
| Review element | Required answer | Decision supported |
|---|---|---|
| Specification | Exact accepted basis and deviations | Defines the product obligation |
| Vessel acceptance | Responsible team's scoped conclusion | Establishes suitability for the intended purchase |
| Parcel evidence | Connection to the offered product | Supports the actual quality review |
| Claimed attribute | Defined scope and supporting evidence | Separates assessed benefit from marketing language |
| Quantity and billing | Agreed unit and any supported conversion | Makes price comparison intelligible |
| Local service | Confirmed location, window and conditions | Establishes the delivered proposition |
| Outstanding condition | Owner and required evidence | Prevents conditional approval becoming unconditional |
Fictional case: a historical event is used as technical approval
A fictional buyer receives a Port Said methanol indication and attaches the public report of an earlier local bunkering event to its approval note. The note treats that event as proof that the current proposal is ready for its vessel.
Review finds no accepted vessel-specific specification, no confirmed connection between the product evidence and proposed parcel, and no final delivery window. The historical event answers none of those questions.
The desk issues a precise requirement, obtains the responsible technical assessment and requests the complete service proposition. The public announcement remains background context rather than being used as a substitute for current acceptance.
Preserve the accepted requirement through delivery
If product description, quantity basis or evidence changes after the order, identify the affected requirement and obtain a scoped assessment. Do not silently replace the original basis with a new attachment or a broader description.
After supply, connect the final documents to the accepted purchase and any authorised amendment. Where conformity, rights or remedies are disputed, check the current agreement and obtain appropriate specialist review.
Common mistakes
Avoid treating a historic methanol delivery as present availability, citing a standard without identifying the accepted edition and assuming an environmental label establishes product suitability. Other errors include unsupported energy conversions or technical substitution assumptions. Define the actual fuel, purpose and service proposition before comparing its commercial value.

Frequently asked questions
Does the earlier East Port Said event confirm today's supply?
No. Obtain a current, complete offer for the actual vessel and requirement.
Does citing ISO6583 automatically settle vessel acceptance?
No. The responsible team must assess the intended product and use on the accepted basis.
Can an environmental description replace quality evidence?
No. Identify and assess the separate product and attribute requirements.
What belongs in the methanol-requirement slot?
Record specification, vessel acceptance, quantity basis, evidence scope and remaining delivery conditions.
