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

Before payment or shipment acceptance, request evidence that connects the machine, the removed part, the candidate replacement, the batch and the supplier record. The minimum set is: machine model and suffix, serial number, nameplate photo, old part number, candidate part number, applicable parts catalogue revision or documented supersession record, and clear component or housing photos. For batch orders, add batch or lot, source and written acceptance records. Model alone is not enough.

1. Separate machine identity from candidate part identity

Machine evidence

Request the machine model and suffix, serial number or product identification number, nameplate photo and installation position. A model number alone does not confirm fitment because suffixes can affect filters, hydraulic connections, electrical parts and mounting details.

Also request the old part number from the removed part, its label, the housing or the existing component. If the old part is damaged or unmarked, ask for clear photos of the component, housing, ports, mounting face and nearby tags.

Candidate part evidence

Request the supplier's candidate part number and the source document used to select it. If the candidate number differs from the old number, ask for the supersession or interchange record rather than accepting a verbal equivalent.

A clear photo of the candidate part or label is useful, but it only shows the part exists and carries the stated marking. It does not by itself prove fitment, quality or authenticity.

2. Confirm fitment with catalogue revision and documented supersession

Fitment check

Compare the old part number or housing marking with the candidate number against the applicable parts catalogue revision for the serial number or production date. If there is no legible old number, request missing evidence instead of guessing.

Useful missing evidence includes component photos from multiple angles, connector or port details, hose end types, mounting hole spacing, data plate details and the exact installation position.

Supersession and revision

If the candidate number is a replacement for an older number, ask for the catalogue revision or manufacturer technical record that documents the supersession. A supplier statement that a part is suitable is not the same as a documented catalogue match.

Do not treat a supplier's photo or a parts catalogue screenshot as proof of every claim. Keep part identity, fitment, provenance, sample results and batch acceptance separate.

3. Request batch, source and acceptance evidence for project orders

Provenance and batch

For batch-critical orders such as filters, seals, hoses, belts, electrical components or fasteners, request the batch or lot number, date code if marked, production date when available, and written source information.

Also ask for current written stock and delivery information if supply is being discussed. Do not rely on a general statement of availability.

Sample and acceptance records

If the supplier offers inspection, test or acceptance records, ask what the record covers and who issued it. A supplier statement or certificate is not automatically a project acceptance decision.

For remote site delivery, request photos or video of the actual packed items and labels before dispatch where practical. This helps confirm the visible markings, but it does not replace later on-site inspection by the responsible party.

4. Next step: request missing evidence before deciding

If evidence is missing

Do not proceed with payment or shipment approval when only a model and a supplier photo are available. Request the missing machine serial, old part number, candidate part number or catalogue revision first.

If the supplier cannot identify the catalogue revision used, ask them to state the exact revision and supply the relevant part number page or record. If that cannot be provided, treat fitment as unverified.

Procurement decision sequence

A useful sequence is: observe what is missing, request the specific evidence, check the candidate number against the old number and catalogue revision, then let the responsible project buyer decide.

Observation: the candidate number looks similar to the old part number, but the serial number is not recorded.

Evidence needed: machine model and serial, old part number, candidate part number, applicable catalogue revision or supersession record.

Next check: compare all four before payment. For batch orders, add batch or lot, source and written acceptance evidence.

Only the responsible project or buyer can decide acceptance using the applicable requirements. This checklist is not a fitment certification or inspection.

Parts Matching Support

If you need help preparing a single-item or batch candidate-number enquiry, prepare your machine model and serial number, old part number, component or housing photos, and any labels or records.
