Name the exact product and controlling specification

EN 590 and Jet A-1 are not interchangeable shorthand for any diesel or aviation fuel. A qualified requirement should identify the applicable specification edition, required test parameters, any jurisdictional or seasonal limits and the certificate or testing evidence expected at the agreed inspection point.

Legacy labels such as ‘D6’ are especially incomplete without a full contractual specification. Nexus does not treat a product name alone as sufficient evidence that a supply programme fits the intended use.

Define the physical programme

The buyer should state the trial quantity, monthly quantity, contract duration, delivery schedule, destination, named Incoterm and receiving capability. Terminal access, airport acceptance, vessel size, storage capacity and delivery windows can determine whether an otherwise attractive indication is operationally possible.

  • Product and complete specification
  • Trial and recurring volume
  • Destination and named delivery point
  • Incoterm and requested delivery window
  • Receiving terminal, airport or storage capability
  • Inspection, testing and document requirements

Verify the buyer and transaction authority

The contracting entity, beneficial ownership, authorized procurement contact, end use and banking identity must be consistent. If an intermediary is involved, its authority and the direct route to the buyer or principal should be clear before controlled supply information circulates.

Proof of financial capacity and banking structure are evaluated in proportion to the transaction and only through appropriate controlled channels. Sensitive banking records should not be submitted through a public website form.

Commercial documents follow qualification

A reliable process moves from a complete requirement through buyer diligence, supply-path authority validation, aligned commercial terms and definitive contract. Inspection, title, payment, logistics and receiving obligations must be reconciled in the executed agreement rather than assumed from a generic procedure.
