The Laboratory Buyer’s Purchasing Requirement

A proforma invoice addressed to a diesel laboratory buyer in Mexico records a requirement for four diesel injectors under reference 0445124011.

The invoice describes the product line as Original New and sets out the commercial terms for a four-piece purchase.

The buyer’s laboratory background is relevant to the purchasing context, but the supplied documents do not identify the intended test procedure, engine model or specific repair work.

The recorded requirement should therefore be presented as a product-sourcing case rather than as a completed laboratory performance study.

Why the Exact Reference Matters

The invoice contains one product line:

0445124011 — 4 PCS

For a single-reference order, the product number is the main identifier connecting the purchasing request with the supplier’s product record.

The exact number should remain consistent wherever the item is described.

A general description such as “four diesel injectors” would omit the most useful technical purchasing detail.

The documents do not provide verified replacement references or engine-fitment information, so those details should not be added to the case without another source.

Commercial and Freight Information

The proforma invoice sets out the proposed purchasing arrangement. An accompanying order-handling record identifies the Mexico order as paid and refers to its freight route.

These records support the existence of a documented procurement process.

They do not, however, contain an independent receipt from the laboratory or a completed injector test report.

The fact that a laboratory purchased or requested a component does not establish that the component passed a particular testing procedure.

Case Summary

This Mexico-market case records a defined four-unit requirement for diesel injector 0445124011 from a laboratory buyer.

The evidence supports the purchasing quantity, product reference and stated commercial condition. It does not establish injector bench-test results, installation performance or an independently verified service-life outcome.
