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

Before buying, request evidence in five groups: machine identity, part candidate identity, batch quality or acceptance, source and provenance, and the project-level document set. Treat model number as a search starting point, not proof of fitment, batch quality or authenticity. For remote Tajikistan infrastructure projects, missing serial numbers, old part photos or candidate numbers should pause purchase until documented evidence is supplied.

1. Why evidence is grouped

Model and serial number serve different purposes. Model narrows the catalogue search, while serial number or serial range helps confirm fitment for parts that changed during production. A photo or supplier statement is not proof of every claim. Keep part identity, fitment, provenance, sample results and batch acceptance separate.

2. Single-item order checklist

Machine identity evidence

Request machine model or suffix, serial number, nameplate photo, old part number from the removed part if available, component or housing photos, installation position, and the applicable catalogue revision.

Candidate part evidence

A candidate number is the replacement part number proposed by the seller or selected from a catalogue. Request the candidate part number, any documented supersession chain if the seller says one number replaces another, and the catalogue revision or manufacturer document that links the candidate to the serial range. Do not accept a generic 'fits SANY' statement without a candidate number.

Batch and quality evidence

Request batch or lot number, date code or batch number on the packaging or label, and any available supplier batch acceptance record or quality document. Keep batch acceptance separate from fitment. A quality document for one batch does not correct a wrong candidate number.

Source and stock evidence

Ask in writing which entity is supplying the part: official dealer, authorised distributor or independent reseller. Ask for current written stock and delivery information for the specific item. This checklist does not confirm supply or delivery conditions.

3. Project-order checklist

Asset and serial register

Create a machine list with model or suffix, serial number, site or region, current hours if relevant, and photos of nameplates or existing components. A project order without serial numbers multiplies fitment risk.

Candidate-number summary

Request a line-by-line candidate number for every part, not a general description. Group the same candidate only when a catalogue or supplied technical document supports it.

Batch acceptance plan

If the project contract requires batch acceptance, ask what documents will accompany each lot: batch or lot number, date code, and any supplier acceptance record or certificate if available. Do not request hazardous testing beyond what the responsible parties require.

Supersession and catalogue revision

For parts known to have updates, request the supersession trail and the applicable catalogue revision in writing. If this is not available, mark the item as unresolved before order acceptance.

4. Missing evidence and procurement next step

When to pause

Pause when the serial number, old part number or model suffix is missing and the candidate part depends on serial range. Pause when the seller cannot give a candidate number or a documented supersession trail.

What to request next

Request machine nameplate photos, old part photos, component or housing photos, installation position, and any label or record. Then ask for the candidate number and catalogue reference. Do not guess from the model name alone.

Parts Matching Support

If you are preparing a parts enquiry or procurement clarification, prepare machine model and suffix, serial number, old part number, component or housing photos, and relevant labels or records. MechLink may support organising single-item or batch candidate-number enquiries and parts-information clarification in this market. MechLink is an external commercial information-support service, not a SANY official site, authorised dealer or certification body. For parts information and procurement enquiries, use MechLink WhatsApp: +77026412810. This contact does not imply local stock or official supply. Ask any supplier for current written stock and delivery information.
