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

Before you accept dispatch or pay, ask for a line-by-line evidence package. The useful question is not only “does the part number look right?” but “which item in this mixed batch is linked to which machine/assembly, and what record supports that claim?” Model names alone do not confirm fitment, batch quality or authenticity.

1. Start from machine and assembly identity, not from the model name

For each order line, request:

• machine model/suffix and serial number or nameplate photo;
• old part number from the removed component or housing if available;
• installation position and component/housing photos;
• applicable parts catalogue revision or documented supersession chain if the old number no longer appears.

A part number may fit one serial range and not another. If the seller cannot show that link, treat fitment as unverified. Request missing evidence instead of guessing.

Pin fitment before the order grows

Ask the supplier to provide a line-by-line table that ties each offered item to the machine/assembly identity it is being offered against. A single quote saying “SANY” is not enough.

2. Keep five questions separate

Do not let one document stand for all claims. Separate:

• part identity: exact part number, old number, supersession;
• fitment: model/suffix, serial range, installation position;
• provenance: new, surplus, removed, refurbished, or unknown;
• sample results: dimensions, material or test records where relevant;
• batch acceptance: batch/lot reference and condition of that specific item.

A supplier statement may support a claim, but it is not proof of every claim. A photo is evidence of appearance, not of internal quality or fitment.

3. Filters: ask for the evidence that changes acceptance

For filters, do not ask for every test certificate. Ask for:

• element or canister dimensions where leakage or housing mismatch is a risk;
• seal/gasket presence and material if the filter is part of a kit;
• batch or date-code marking on the label or shell if visible;
• manufacturer data sheet or technical record where the supplier claims performance.

If the filter is hydraulic or high-efficiency, ask which specific rating or test is being claimed and request the source document. Do not guess a rating from a photo.

4. Seals and hoses: material and markings matter

For seals, ask what material code is on the package or band and whether the dimension matches the old part. A visual “looks the same” is not a measurement.

For hoses, request the layline markings or label information: dash size, length, pressure rating or hose type if marked, and fitting thread/seat identification. If the hose is cut to length, ask for measured length and end fitting confirmation against the removed assembly. If the marking is missing or illegible, ask for a better photo or measurement before acceptance.

5. Undercarriage items: link wear state to position

For undercarriage parts such as track shoes, pins, bushings, rollers or idlers, fitment is not only part number. Ask:

• the serial-number range or undercarriage model the item is offered for;
• the position in the undercarriage if the batch mixes left/right or front/rear items;
• measured pin/bushing or shoe dimensions if the item has been measured;
• whether it is new, removed, rebuilt or reconditioned.

Request detailed wear measurements only where wear affects acceptance. Do not accept a batch photograph as a substitute for item-by-item condition.

6. Candidate numbers: make every item traceable to a record

Ask the supplier to assign a candidate number to each item or homogeneous sub-batch. That number should appear on the quote, photograph, measurement sheet, batch label and invoice line. This prevents a thick document pack from becoming decoration.

What a thick pack can hide

A large PDF may contain a general catalogue, a generic quality policy and a warehouse photo. Those do not link a specific item to its stated part number, batch, dimension or condition. Ask: “Which page belongs to line 3, and what does it prove?” If the answer is unclear, the evidence package is incomplete.

7. Request dated written supply terms for unresolved questions

Procurement matters should be put in writing before dispatch:

• item list and quantity with candidate numbers;
• condition description for each item;
• documents that will be provided for each line;
• what the supplier states about fitment, dimensions or batch and what remains unverified;
• inspection or discrepancy window after delivery.

Ask the seller to mark any unresolved question in the quote. For example: “Exact fitting thread not yet confirmed” or “Batch label photo pending.” If it is unresolved now, it should not become a surprise at site. Only the buyer and its technical representative can decide acceptance using the applicable requirements.

8. Procurement next step: ask for one linked response

Send the supplier a short request that can be checked quickly:

• model/suffix, serial number and old part number;
• component/housing photos and installation position;
• candidate number for each line;
• condition and batch reference;
• the specific record that supports the claim for that line.

If you want help organising a batch enquiry by model + serial number + old part number and component photos, a third-party commercial service such as MechLink may support candidate-number organisation.
