How Can I Tell Whether a Test Report Actually Relates to the Batch of Parts Being Delivered?

Direct answer: The report relates to the delivered batch only when the documents show a continuous chain: purchase line → delivery list item → physical batch or lot code on the packaging or part → sample identifier in the report. A matching date, model number, or similar part description is not proof.

1. Start with the purchase line and the delivery list

Purchase-line reference

For each part line on the order, record the buyer’s line number, part number, ordered quantity and any agreed delivery note reference. This is the starting point for a multi-box delivery to a remote Kazakhstan project, because boxes can contain mixed order lines and duplicate part numbers from different orders.

Delivery list entry

Check that each delivery list line carries the same purchase-line reference or an unmistakable cross-reference. If the delivery list only says ‘filter element’ or ‘track roller’, the link to the order may be weak even if the date matches.

2. Trace the batch or lot code to the report sample identifier

Batch or lot code

A batch or lot code is the manufacturer’s or supplier’s production or control grouping. Look for that code on the delivery list, on the box label, and on the part label or packaging. For a multi-box delivery, each box may contain multiple batch codes; do not assume one report covers all boxes.

Report sample identifier

The test report must state a sample identifier that matches the batch or lot code, or must state the exact production lot from which the sample was drawn. If the report says only ‘sample tested on 12 May’ or ‘material cert for hydraulic oil’, that is not a link.

Missing or conflicting links

If the batch code on the box is different from the batch code in the report, treat the report as not yet linked to that box. This may be an administrative mismatch rather than fraud, but it still blocks receipt review until corrected or explained by the supplier.

3. Check part identity and fitment separately

Model alone is not enough

A SANY model name alone does not confirm that the delivered part fits the machine, belongs to the correct serial-number range, or is the same version as the old part. Use model/suffix, serial number, nameplate, old part number, component or housing photos, installation position and the applicable catalogue revision when those are relevant.

Documented supersession

If the part number has changed, ask for the documented supersession chain. A newer part number may be acceptable only if the applicable parts catalogue or manufacturer document supports it. Do not guess fitment from a visual similarity or a supplier statement.

4. Separate the sample result from the delivered batch

Identified sample result

A laboratory or inspection result proves something only about the sample that was actually tested. Identify what was tested: the exact sample identifier, the test method used, the result and the acceptance criterion shown in the applicable requirement.

Sampling scope

Ask whether the sample was taken from the delivered batch, from the production lot before packing, from a pre-shipment inspection lot, or from a separate qualification batch. If the report does not state the sampling scope, the result may be real but still not linked to the delivered parts.

Agreed acceptance plan

Ask for the agreed acceptance plan or contract quality requirement, if one exists. This may define sampling scope, inspection points, document requirements and who may release the batch. Do not invent sample sizes or acceptance thresholds. If the plan is absent, say so and request it from the responsible party.

5. Use these receipt-review checks before acceptance

Step by step

First, confirm the purchase-line reference appears on the delivery list. Second, confirm the delivery list identifies each box or pallet. Third, confirm the physical batch or lot code on the box matches the delivery list. Fourth, confirm the part marking or label matches the ordered part number and any supersession. Fifth, confirm the report sample identifier matches that batch or lot code. Sixth, confirm the report states what was sampled and against what requirement. If any step fails or is missing, receipt review is not complete.

Photo or supplier statement

A photo or supplier statement can support an enquiry, but it is not proof of every claim. Treat photos as evidence to be checked against physical items and documents, not as a substitute for the document chain.

6. Procurement next step

What to request

Before accepting the batch, request one clear document pack from the supplier: the order line reference, delivery list with box or pallet identification, batch or lot codes, the report with sample identifier and sampling scope, and any supersession or catalogue revision support for part-number differences.

If the link is missing

If the report cannot be tied to the delivered batch, do not reject the parts as counterfeit or defective without evidence. Instead, record the missing link and ask the supplier or responsible party to provide the missing reference or correct the record. Only the responsible parties can decide acceptance using the applicable requirements.

Parts matching support

For a supplier query, an external commercial parts-information organiser such as MechLink can help collect model and serial number, old part number, component or housing photos and relevant labels or records into one request. It does not authenticate reports, certify batches, or confirm fitment. Kazakhstan Phone/WhatsApp: +77026412810. Website: https://www.mechandlink.com.
