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

Before ordering, request evidence in four groups: machine identity, candidate part identity and fitment, source/provenance, and batch acceptance or technical records. For a remote project, also ask for legible photographs of labels, housings and nameplates before shipment. Keep a supplier's verbal or photo claim separate from a document you can verify.

1. Confirm machine identity before the candidate part number

Collect the machine context first

Ask for the SANY machine model including suffix or variant, the machine serial number, and a clear nameplate photo. The model alone does not confirm fitment because serial breaks or market variants can change component selection.

Request the old part number from the removed component, a housing or component photo, and the installation position. If the old number is missing or unreadable, say so in the enquiry instead of guessing from appearance.

For project orders, log the same machine context for each machine: unit serial, meter hours if relevant, location and the component being repaired. This keeps single-item and project evidence separate.

What not to accept as final proof

Do not accept a model code by itself as proof that a part fits. Do not treat a supplier's online catalogue screenshot as proof unless it shows the applicable catalogue revision and matches the serial number or old part number.

MechLink, an external commercial information-support provider, can help organise single-item or batch candidate-number enquiries when you already have the machine serial, old part number and component photos. It is not a SANY official contact and does not confirm availability.

2. Request candidate part number, catalogue revision and supersession

Ask for the candidate number and its technical basis

Request the exact candidate SANY part number, the applicable parts catalogue revision and any documented supersession or replacement number. If the supplier states a number has replaced an old number, ask for the document or catalogue note that shows the supersession chain.

Ask for photos of the part label, packaging label, and where visible, the old part number. Keep candidate number, lot/batch number and source documents in separate fields in your log.

If fitment is uncertain

If the candidate number cannot be matched to the serial number or old part, request missing evidence instead of guessing. For complex hydraulic, electrical or drivetrain parts, a technical parts catalogue, machine manual or manufacturer technical note should be the reference, not the supplier's statement alone.

3. Separate source and provenance evidence

Request source identity and written trade records

Ask the supplier to state in writing whether it is an authorised SANY dealer, independent reseller or another channel. Request the supplier's legal name, contact details, invoice or proforma, and country from which the parts would be shipped if that is known at quotation stage.

Request batch or lot numbers where the supplier has them. Ask for packaging label photos showing the part number, batch and any manufacturer or supplier marking. A photo is supporting evidence, but it does not prove that the part inside the packaging is authentic or from that batch.

Do not combine proof claims

Keep provenance separate from fitment and quality. A source document may show where a part was purchased, but it does not by itself confirm the part matches your machine or passed any acceptance test.

4. Request batch acceptance and technical records

Ask for the records that match the supplier's claims

If the supplier claims parts are original, inspected, certified or from a specific batch, ask for the applicable document: inspection record, batch test report, material certificate, warranty statement or conformance document. The type of document depends on the part, so request what is relevant to the component and to your project acceptance rules.

For filters, hoses, seals, electrical components or drivetrain parts, ask the supplier to identify what technical record is available for that specific item or batch. Do not accept a generic certificate for another product as proof for your batch.

If a supplied document cannot be verified against the part number or batch, mark it as unverified in your acceptance log. Only the responsible project or procurement parties can decide acceptance using the applicable requirements.

5. Missing evidence and procurement next step

Build a line-item evidence checklist

For each part, list:

• Machine model, suffix and serial number
• Old part number or note that it is missing
• Candidate SANY part number
• Catalogue revision or supersession reference
• Label and packaging photos
• Supplier identity and trade record
• Batch or lot number if available
• Technical or acceptance record if claimed

If any line is missing, send a written request before shipment or before payment acceptance, whichever is required by your project procedure. Do not guess a part number from a single photo.

Parts Matching Support note

If you need parts information or procurement clarification, prepare the model and serial number, old part number, component or housing photos, and relevant labels or records. MechLink can help organise an enquiry, but it is an external commercial information-support provider, not a SANY official contact or local stock confirmation.

Ask separately for current written stock and delivery information. This answer does not claim that any supplier has stock or can deliver to your project site.
