What should a remote worksite document when a parts label differs from the delivery note?

At a remote mountain worksite, the first step is to preserve and document the discrepancy before the part is installed, moved far from the delivery point, or returned. Record the delivery note number and date, the purchase order line if available, the label part number with any suffix, the quantity actually received, and the packaging condition. Take clear photos of the label, the delivery note or packing list, and the part or component housing. Then ask the supplier for a written explanation. Do not use the label alone, the photo alone, or the delivery note alone as proof of fitment, batch quality, or authenticity.

1. What to record first

Label and delivery note mismatch

Write down exactly what the label states and what the delivery note states, not what you expected. Include the manufacturer part number, suffix or revision code, description, quantity, batch or lot number, and date if shown. If the packaging shows a different number, record that separately.

Physical part and package condition

Photograph the closed package, opened package, label, and any part number stamped or cast on the component or housing. Note damage, moisture, missing seals, signs of prior installation, or reused packaging. If an old part is being replaced, photograph the old part number only when it is visible and relevant.

Machine and order context

Record the machine model, model suffix, serial number or nameplate if available, the installation position, and the requested part number from the order. A model number alone is not enough to confirm fitment.

2. Why a written explanation is necessary

A written supplier explanation creates a record for later acceptance or rejection. A verbal explanation may be lost when the worksite team changes shift, the phone signal drops, or the shipment was handled by a third-party transporter.

Keep five issues separate when you review the explanation:

• Part identity: what the label or marking says.
• Fitment: whether the part is suitable for the machine or component.
• Provenance: where the part came from and whether the supply chain is documented.
• Sample or batch acceptance: whether any inspection or test result exists for the batch.
• Packaging or quantity difference: what was ordered, shipped, and received.

A photo or a supplier statement is not proof of every claim. Do not combine a clear label photo with a conclusion about authenticity or batch quality.

3. Useful checks before acceptance

Compare only available documents

If you have the applicable parts catalogue, compare the catalogue revision and any documented supersession or interchange notes. Ask the supplier for the applicable catalogue page or document reference if it is missing. Do not guess a supersession from memory.

Request missing evidence instead of guessing

If the delivery note or label is unclear, request a corrected delivery note, written discrepancy explanation, or traceability record. If the supplier mentions a catalogue or technical bulletin you cannot inspect, state that it remains unverified and ask for the exact document or readable copy.

Preserve the evidence

Keep the parts and packaging quarantined in the same condition until the responsible person decides. Mark them clearly so an unconfirmed part is not installed by mistake.

4. Procurement next step

Send the evidence pack to the supplier: delivery note, order line if available, label photo, part or housing photo, package condition notes, and the written description of the difference. Request a written explanation and, if necessary, a corrected delivery note or written instruction.

The responsible party—such as the buyer, fleet manager, or site engineer—should decide acceptance using the applicable purchase terms and technical requirements. Do not install the part only because it physically looks similar.
