When an Algerian parts order specifies left or right, it should define the viewing direction and include an installation-location diagram that identifies the vehicle's front and rear. Procurement personnel photographing from the front and a technician describing the part while seated inside may use different perspectives. A formal order must not retain this ambiguity.
A manufacturer catalog such as the official Tesla Parts Catalog can show how locations are identified. Every actual order must use the relevant brand catalog's definition; Chinese words for left and right cannot establish every manufacturer's numbering rules.
Draw the Vehicle's Front Direction on the Inquiry Attachment
The location diagram need only show the front, rear, and target area clearly. Separately state the photography direction so a remote supplier can relate the physical item to the vehicle location.
Do not substitute "driver's side" for a direction definition unless the vehicle layout has been confirmed. Check whether documents from different supply markets use consistent directions; translators must not enter habitual expressions directly into an ordering field.
Store the diagram with the vehicle identity. If an image of another vehicle is used as a reference, prominently identify it as an illustration of location only, with actual fitment still pending verification.
Make the Diagram, Wording, and Part Number Constrain One Another
For a side-specific order, retain the original catalog wording and its translation in the same line and ask technical personnel to confirm them. Do not say "the other side" only in chat while leaving the old number on the formal order.
| Identification method in the order | Verification focus | Action if a conflict appears |
|---|---|---|
| Location diagram | Whether the vehicle's front is identifiable | Provide a new directional diagram |
| Original catalog wording | Whether it follows that brand's definition | Ask the supplier to explain the mark |
| Original-part label | Whether the number is clearly visible | Retake the complete part and label |
| Quoted part number | Whether it matches the accepted location | Pause confirmation of that order line |
| Physical-item packaging | Whether it belongs to the quoted item | Retain the packaging and request review |
The table entries should all identify the same location. If an item cannot be supplied, state the reason and alternative confirmation method rather than treating the blank as checked.
Watch for Misunderstandings Caused by Mirrored and Cropped Photographs
A phone's front camera, forwarded image, or editing software may change how the scene appears. Retain original photographs in the procurement record and do not flip them casually. If direction is unclear, use continuous wide and close views of the vehicle to locate the part.
If left and right parts look similar, do not make the final decision by appearance. Interfaces, fastening points, and functional versions require confirmation against applicable documents, and procurement staff should not let the warehouse substitute items that look alike.
If a customer changes the order to the other side, create a clear change notice listing the canceled and new items. Retain the old order as history, but prevent both orders from being used for stocking simultaneously.
Carry Direction Information to the Receiving Desk
At receipt, the warehouse should compare the order, label, and location description before entering the quantity. If the label and photograph disagree, mark the part separately as pending confirmation rather than rushing it to the repair bay.
Use the Starvia Automotive export-service contact guide to request catalog and version information from the complete-vehicle supplier. Confirm separately whether it handles the specific parts business.
Qualified personnel still perform the pre-installation review. Procurement direction records support communication but cannot replace technical fitment and safety checks.
Example, subject to the contract and actual vehicle. If a technician requests the vehicle's left-side part while the supplier returns a photograph taken from the front showing the right-hand side of the image, first mark the target on the same location diagram and then confirm the original catalog wording. Do not repeatedly write left and right on the photograph to explain. Send the confirmed image with the order, let the warehouse use that final attachment, and retain the old screenshot only as communication history.
FAQ
Is writing driver's side clearer than writing left side?
The vehicle layout and catalog definition still require confirmation. Driver's side alone may remain ambiguous.
Can two visually identical side parts be interchanged?
Applicable documentation must determine this. Similar appearance does not prove interchangeability.
If the chat says to change sides, must the order be reissued?
Create a clear change record so the warehouse does not stock against the original number.
What if the original part has been lost?
Provide the vehicle identity, a clear location diagram, and the applicable catalog basis, and ask the supplier to state confirmation conditions.
If side-specific part information is difficult to reconcile, request vehicle documentation through the Starvia Automotive contact page, or explain the specific directional and part-number question through WhatsApp.
