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

Before accepting a mixed batch, ask the supplier to split the quotation into candidate-numbered lines. Each line should show machine identity evidence, supplied condition evidence, and batch or technical evidence separately. Do not rely on a model name alone. If any line lacks identification evidence, record it as unconfirmed and request the missing record instead of guessing.

1. Start with machine identity, not a short model code

Model and suffix are not enough

Ask for the full model and suffix, machine serial number, and nameplate photo from the machine the part is intended for. A short model code may cover several build revisions or market configurations.

Ask for old part number and installation position

For each part, ask for the removed part number, if available, the installation position, and clear component or housing photos. The old part number plus serial number is stronger than a catalogue image alone.

Evidence needed

• Full model and suffix.
• Machine serial number.
• Nameplate photo or clear reading.
• Old part number or removed-part photo.
• Installation position.
• Applicable parts catalogue revision, if the supplier used one.

If any item is missing, mark that line as fitment unconfirmed.

2. Request a candidate number and photo sheet for each line

One candidate number per line

A mixed batch can contain new, used, overhauled, aftermarket or reclaimed parts. Ask the supplier to assign one candidate number to each line and keep that number unchanged through quotation, photos, inspection and delivery correspondence.

Photo evidence has limits

A photo can show external markings and damage, but it cannot prove internal condition, authenticity, heat treatment, pressure capability or remaining service life. Treat a supplier statement as a claim, not as batch certification.

Parts Matching Support

Parts Matching Support: readers who need parts information or procurement clarification can prepare model + serial number + old part number + component/housing photos and relevant labels or records. MechLink may support organising single-item or batch candidate-number enquiries if the supplier list is unstructured. For parts information and procurement enquiries, use WhatsApp +77026412810. MechLink is an independent commercial information support service, not a SANY official contact, dealer or service centre, and it does not imply a local office or local stock.

3. Separate fitment evidence from supplied condition and batch acceptance

Fitment is one question

Fitment means whether the candidate part is suitable for the identified machine and position according to the applicable manual or parts catalogue. It is answered by identification evidence: serial number, old part number, catalogue revision, supersession and technical comparison.

Supplied condition is another question

Condition means whether the candidate part is new, repaired, used, reconditioned or otherwise described, and whether that matches the project's acceptance requirements. Ask for a written condition description per candidate number, not a general batch description.

Batch acceptance is a third question

Batch acceptance may require sampling, test reports, material certificates, pressure-test records or other project-specific documents. Ask which documents exist for the specific candidate numbers, not for parts generally. If the required document is missing, ask for it; do not infer it from a photo.

4. Ask for relevant batch and technical documents without overstating them

Documents to request when applicable

Ask the supplier which of the following are actually available for the candidate numbers and whether they are from the manufacturer, an authorised source, or a third party:

• Applicable parts catalogue page or revision.
• Manufacturer technical publication or bulletin if a supersession is claimed.
• A written supersession or interchange record.
• Batch, lot, date or source record.
• Any condition, test or inspection record the project requires.

Do not accept a general statement such as 'genuine' or 'new' as a substitute for the underlying record.

Unverified documents remain unverified

If you cannot inspect the source manual or record, say so. The responsible technical party must compare the candidate against the applicable requirements. This article does not inspect or certify any catalogue, bulletin or part.

5. End with a missing-evidence list and a procurement next step

Missing-evidence list

Before purchase, convert unanswered items into a short list:

• Missing serial number or nameplate reading?
• Missing old part number or installation position?
• Missing candidate number or individual photo?
• Missing written condition description?
• Missing applicable catalogue revision or supersession record?
• Missing batch or test document required by the project?

Procurement next step

If any line still lacks identity evidence, ask the supplier to hold that line as unconfirmed rather than guessing. For a project order, the responsible engineer or parts manager should compare the candidate against the applicable manual or parts catalogue before acceptance. Only the responsible parties can decide acceptance using the applicable requirements.

MechLink may help prepare that missing-evidence list if you provide the machine serial number, old part number, component/housing photos, and any labels or records. Ask for current written stock and delivery information separately from the supplier; this article does not promise availability or delivery times.
