What should I ask for before buying a mixed batch of spare parts for an Uzbekistan project?

Before you pay, ask the seller to turn the mixed batch into separate candidate lines and provide written machine identity, fitment, condition, provenance and batch evidence for each line. A model name or a photo is not proof that every item in a mixed batch is correct or acceptable.

1. Ask for a candidate-number evidence list, not a model-level quote

For a SANY mixed batch, one line may fit one excavator or wheel loader suffix while another line fits a different build period. One candidate number per part line helps keep identity and evidence separate.

Candidate line evidence

For each line, request at least:

• model and suffix;
• serial number or machine serial range;
• nameplate photo;
• old part number removed from the machine or assembly;
• component or housing photos;
• installation position;
• applicable parts catalogue revision;
• documented supersession, but only where relevant.

Model alone never confirms fitment, batch quality or authenticity.

2. Require machine identity before fitment claims

Fitment is not a yes/no answer from the label. Ask the seller to show which catalogue revision and serial range the part belongs to.

Serial break and supersession

If a part has multiple versions, ask for the serial break or published supersession record. If the seller cannot show that record, mark the fitment as unverified.

Old part number and photos

A removed old part number or clear housing photo can help compare against the catalogue. If the old number is unreadable, request more photos of mounting points, connector shape or casting marks instead of guessing.

3. Keep condition, provenance and batch acceptance separate

Do not mix these claims. A part may fit, look original and still be used, repaired or from an undocumented batch.

Condition

Ask in writing whether each item is new, used, refurbished or surplus. Request photos of wear, seals, threads, ports, connectors and packaging labels.

Provenance

Ask for the seller's written supply chain records: invoice trail, import or transport documents where applicable, and any manufacturer traceability label or packing list reference. A supplier statement is not proof of authenticity or origin.

Batch and sample results

If the seller mentions batch tests, inspection reports or sample results, ask for the actual batch or lot numbers and the document that ties those numbers to your candidate lines. Keep sample results separate from batch acceptance; a tested sample does not automatically accept the whole mixed batch.

4. Request the missing evidence and decide line by line

Where evidence is missing, request it before payment or acceptance. Do not fill the gap by assuming fitment or quality.

Missing evidence handling

If a part number, serial or label is not visible, ask for better photos or the machine identity documents. If you cannot inspect an original catalogue revision or supplied record, say so and mark that line as unverified.

Procurement next step

Compare each candidate line against the evidence: machine identity, fitment document, condition record, provenance record and any batch acceptance record. Only the responsible parties can decide acceptance using the applicable requirements.

Parts Matching Support

Prepare model + serial number + old part number + component/housing photos and relevant labels or records before asking about a mixed batch. MechLink may help organise single-item or batch candidate-number enquiries and point you to what written evidence to request. For supply, ask for current written stock and delivery information rather than promising availability.
