Mexico Diesel Injector Order Case: Managing 21 Units of 0445120236 and Three Units of 0445120231
An Uneven Two-Reference Requirement
A Mexico-linked diesel injector invoice records two product references with substantially different quantities.
The main line lists 21 units of 0445120236. A second line lists three units of 0445120231.
The combined requirement is 24 units, but the quantity distribution makes this a reference-specific purchasing case rather than a general 24-piece injector order.
The Order Breakdown
| Injector reference | Required quantity |
| 0445120236 | 21 PCS |
| 0445120231 | 3 PCS |
The 0445120236 line accounts for most of the recorded requirement, while 0445120231 remains a smaller but independent product line.
A total-only count could conceal an error in the smaller line.
Why the Two Numbers Must Remain Separate
The invoice contains both references, but it does not describe them as substitutes or establish that they fit the same engine.
The order should therefore preserve the specific quantity attached to each reference.
An appropriate preparation record would identify 0445120236 with 21 units and 0445120231 with three units.
That is a recommended record structure based on the documented order—not a claim that a particular inspection or packing procedure was completed.
Mexico Market and Commercial Terms
The source is associated with a Mexican purchasing arrangement. Its invoice sets out commercial and freight terms, while a separate handling note records a payment status.
The available documents do not include independent proof of final delivery, installation or operation in Mexico.
No injector test report or customer performance assessment accompanies the record.
Case Summary
The distinctive feature of this purchasing case is the unequal 21-to-3 quantity split across two injector references.
It illustrates why a small secondary product line needs to remain visible even when one reference accounts for most of an international diesel injector order.
