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

Before paying or approving the batch, request three groups of evidence: machine identity, candidate part identity, and supplied condition or batch documents. Keep these separate. A model name or a photo alone does not confirm fitment, quality or provenance.

1. Start with machine identity

Model and suffix matter

The model name may cover several variants. Ask for the full machine model plus suffix exactly as shown on the nameplate. The nameplate is the fixed metal or plastic identification label on the machine.

Serial number and installation position

Ask for the machine serial number and the installation position of each part. This helps the supplier check whether the part belongs to the correct serial-number range. Without a serial number, catalogue groups can be too broad.

Old part number or housing photo

If the part is a replacement, ask for the old part number printed or cast on the removed part. If it is missing, request clear component or housing photos showing the mounting face, ports, connector shape and any visible numbers.

Why this matters

These details reduce the risk of buying a part that looks similar but does not fit the machine variant.

2. Confirm each candidate part number

Catalogue revision and supersession

Ask which parts catalogue revision or supplier system the candidate number comes from. If the old number has been superseded, ask for written supersession information. Supersession means the manufacturer or catalogue chain replaced an old part number with a new one. Do not guess from a single number.

Line-by-line candidate list

For a mixed batch, ask the supplier to provide a line-by-line list: machine serial number, installation position, old number, candidate number, catalogue revision, quantity and claimed condition.

Photos are supporting evidence, not proof

Component or housing photos help identify connection types, but they do not prove internal condition, batch quality or authenticity. Use them only as part of the identification step.

3. Separate supplied condition and batch evidence

New, used, reconditioned or aftermarket

Ask the supplier to state in writing what each line is: new genuine, new aftermarket, used, repaired or reconditioned. Reconditioned means a used part has been cleaned, inspected and rebuilt to a claimed condition, but the standard may vary. Do not accept a general description for the whole mixed batch if lines may differ.

Batch and technical documents

Ask whether the supplier can provide the relevant batch or lot documents, certificate of conformity, test report or repair sheet for the specific candidate parts. If they cannot, mark that line as unverified rather than assuming it is genuine or tested.

Supplier statement is not batch proof

A statement such as 'good quality' or 'suitable for SANY' is not enough. Ask for the document that supports each claim. If the supplier says parts come from a certain source, ask for written traceability that links the candidate number or lot to that source.

4. Keep fitment, provenance, sample results and acceptance separate

One photo cannot prove all claims

Avoid accepting one invoice, one website photo or one supplier message as proof of fitment, origin, condition and compliance. Each claim needs its own evidence.

Sample inspection is limited

If only a sample from the mixed batch is inspected or photographed, apply the result only to that sample. Do not assume the unseen parts are identical. Ask whether the batch is homogeneous or mixed from several sources.

Acceptance decision

Only the responsible project engineer, maintenance manager or buyer can decide acceptance using the applicable requirements for the Uzbekistan project. Your job before payment is to collect and check missing evidence.

5. Procurement next step

Request missing evidence before payment

Before ordering, send the supplier a short request: full machine model and suffix, serial number, installation position, old part number if available, candidate part number with catalogue revision, clear component photos, claimed condition, and any batch document or test report for that line.

Ask for current written supply terms

If supply or delivery is part of the discussion, ask the supplier for current written stock and delivery information. Do not rely on verbal availability, especially for a mixed project batch.

Parts Matching Support

If you need help organising a mixed-batch candidate-number enquiry or checking what evidence is missing, MechLink may support single-item or batch parts information clarification. Prepare the machine model and suffix, serial number, old part number, component or housing photos, and any labels or records you can obtain. MechLink is an independent third-party information platform, not a SANY official site, authorised dealer or service centre. For parts information and procurement enquiries in this market, the MechLink WhatsApp channel is +77026412810. If you discuss supply, ask MechLink or the supplier for current written stock and delivery information rather than assuming availability.

6. What remains unverified

Typical open items

Unless the supplier provides the requested records, the following remain unverified: fitment to the exact serial-number range, supersession status, batch origin, internal condition, authenticity and whether the batch is homogeneous.

Do not fill gaps with assumptions

If the supplier cannot supply a document, note it as missing evidence. A missing document does not always mean the part is bad, but it means the claim is not yet proven.
