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

Before paying for a mixed batch, ask for a line-by-line candidate list tied to each machine serial number, requested part number or old part number, installation position, and supplied condition. Request clear photos of nameplates, labels, housings and wear surfaces, plus any available batch or technical documents. Do not accept model-only confirmation. If evidence is missing, ask the supplier to mark that line as unverified instead of guessing.

1. Start with machine and part identity

Model and suffix are not enough

Ask for exact model, suffix or configuration code, and machine serial number. Machines of the same model can have different production options, hydraulic configurations, axle or engine details. A serial number lets the buyer check the correct parts catalogue for that specific machine.

Nameplate and old part number

Request a clear photo of the machine nameplate and the existing or removed part label. If the old part number cannot be seen, ask for component or housing photos from several angles and the installation position. This gives a useful cross-check when the supplier's candidate part number does not match.

Catalogue revision and supersession

Ask which parts catalogue revision or edition was used. If a part number has been superseded, request the old-to-new relationship document. A supplier statement that a part fits is not enough without the applicable catalogue or technical record.

2. Organise the mixed batch as a candidate list

Assign a candidate number to every line

Each line in the batch should have a supplier or buyer candidate number. The line should show quantity, part number, old part number, machine serial number or asset, installation position, supplied condition, and the photo file name. This separates identity from later batch acceptance.

Confirm supplied condition for each line

For every line, confirm whether the part is new, used, refurbished, repaired, or as-removed. Ask for close photos of sealing faces, threads, connectors, mounts, wear surfaces, corrosion and damage. A general batch photo does not prove the condition of each individual line.

3. Separate fitment, provenance and batch acceptance

Fitment evidence

Fitment should be checked against the applicable machine parts catalogue, not only against a visual match. Request the catalogue reference or document that supports each line. If one line has no catalogue support, mark it as fitment unverified.

Provenance evidence

Ask for written origin or procurement trace, such as supplier invoice, packing list, or manufacturer release document if available. A photo of a box or a logo is not proof of origin. If official manufacturer records are not available, say that provenance remains unverified.

Batch and technical documents

For batch orders, ask whether any manufacturer certificates, inspection reports or conformity documents apply to the exact batch or serial number. The buyer's engineer or responsible party should define the acceptance criteria before payment. Do not invent standards, test readings, or certificate numbers.

Sample results

If a sample inspection is mentioned, request the actual report that corresponds to the exact batch or candidate line. Do not apply a sample result from one batch to another batch without a written link.

4. Missing evidence that should delay payment

• No machine serial number or asset link: identity unverified.
• Only a model name: fitment unverified.
• No old part number or installation position: fitment support weak.
• No clear component or housing photos: supplied condition unverified.
• No label or packaging photo with part number: candidate number unverified.
• No relevant batch certificate or technical record: batch acceptance open.
• Supplier statement used as sole proof: do not treat as technical confirmation.

If a line has any of these gaps, ask the supplier to correct the candidate list or provide the missing document before final acceptance.

5. Procurement next step

Request the checklist package before deposit or release. The minimum useful package for a mixed batch is: machine serial number, part number or old part number, candidate number, condition photos, and any available batch or technical records. Then have a qualified person compare each line against the applicable parts catalogue or maintenance manual.
