What evidence should I request before buying SANY parts for a remote Tajikistan infrastructure project?

Before payment, ask the supplier to separate four questions: what machine is involved, what part number is proposed, what batch or source evidence exists, and what technical document supports fitment. For a single item, request the machine serial number or nameplate, the old part number or component/housing photo, and the proposed candidate number from a document. For a project order, request the same per line item plus a candidate-number list and written batch/source records. Do not accept model name alone.

1. Start with machine identity, not model alone

Model and suffix are a search starting point, not fitment proof. A serial number, nameplate, old part number, component or housing photos, installation position, and applicable catalogue revision are the documents that connect a part to a specific machine.

Remote sites in Tajikistan may have limited return windows, so wrong parts are more expensive than missing paperwork.

Request this machine identity evidence:

• full model and suffix
• serial number or PIN
• nameplate photo
• old part number from the removed part
• component or housing photos
• installation position

For a project order, link every line item to a specific machine serial number. Do not use a site-level model list as a substitute.

2. Request candidate part evidence before accepting a quote

A candidate number is the supplier's proposed part number. It is not confirmation of fitment, batch quality, or authenticity.

Ask the supplier to state the candidate number in writing and link it to the old part number and machine line item. A description such as 'boom cylinder seal kit' is not enough.

Single-item order

Request:

• exact candidate part number
• old part number from the removed part
• applicable catalogue revision or parts list reference
• photo of the label, box, casting, or housing
• written statement of what the supplier has verified and what remains unverified

Project order

Request:

• line-item candidate-number list
• one photo set per line item
• batch or lot number where available
• written source record linked to each line item
• written acceptance and rejection procedure before shipment

A photograph helps identify differences, but a photograph alone is not proof of every claim.

3. Keep batch, source, and authenticity evidence separate

Part identity, fitment, provenance, sample results, and batch acceptance should stay in separate evidence groups. Do not let a supplier photo double as a batch record or sample inspection result.

A batch or lot number is a traceability code that links parts to a production run or package. Ask for it when the supplier says it exists.

Useful evidence includes:

• batch or lot number on the part or packaging
• production date where relevant
• written source record such as supplier name, document number, and date
• for filters or consumables, shelf life or production date if applicable

A batch number and source record support traceability. They do not by themselves guarantee authenticity. If authenticity is critical, the responsible buyer may need further verification through the applicable SANY channel or an agreed acceptance inspection.

4. Use applicable technical documents for fitment

Use actual applicable manuals, parts catalogues, manufacturer documents, or supplied technical records. If the supplier says a part fits a model, ask for a catalogue extract or manual reference that includes the applicable serial range. If that is not provided, record the fitment claim as unverified.

Supersession means a later part number replaces an earlier number. Accept supersession only when it is documented, for example in a catalogue revision or written manufacturer notice. Do not accept 'this replaces the old number' by phone alone.

Photos of the removed part and the proposed candidate side by side can help distinguish variants, but they do not replace catalogue or serial-range evidence.

5. Missing evidence and procurement next step

If evidence is missing, request the specific missing item and hold the order until the supplier answers in writing. Do not guess a part number or serial-range match.

For remote project orders, consider a small controlled first order or a clear arrival inspection step, but do not treat this as proof of fitment. Only the responsible parties can decide acceptance using the applicable requirements.

MechLink may support organising candidate-number records and batch enquiries, especially when the order includes many line items. MechLink is an external commercial parts information service, not a SANY official site, authorised dealer, or certification body. If supply is discussed, ask for current written stock and delivery information rather than assuming availability.

6. Parts matching support

If you need help preparing the evidence package, collect the model and serial number, old part number, component or housing photos, and relevant labels or records.
