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

Direct answer: ask the supplier to give every order line a candidate number tied to a physical part or sealed package, and request only the evidence relevant to that line. Model name and a thick certificate file are not enough. The main risk is a part listed by model with no proof of which exact item was inspected, fitted, sampled or accepted.

1. Start with line-item identity, not just the machine model

Request that the quotation or proforma invoice carries a line identifier or candidate number for each part, kit or sealed pack. The candidate number is the thread that connects a photo, label, dimension check or test record to the part you are buying.

For each line, ask the supplier to state which evidence belongs to that candidate number. Do not accept a general statement such as for SANY excavator as proof of fitment.

Required identity checks before payment

Ask for the machine model and suffix, machine serial number or nameplate, the assembly or housing position, and the old part number if one exists.

For superseded part numbers, ask for the documented supersession chain or catalogue revision rather than guessing from a similar number.

For filters, the old part number and housing photo often matter more than the machine model alone. For seals, request the installed dimensions and material. For hoses, request the assembly length, end fittings and pressure class. For undercarriage parts, request the track pitch, pin and bushing dimensions, or the wear state if used.

2. Ask for the right evidence by part type

Not every item in a mixed batch needs the same evidence. A new spin-on filter may need a batch or date trace, while a used undercarriage link may need a written wear measurement and donor-machine record.

Filters

Ask whether the filters are new or old stock, and request the production date, batch or lot reference where the supplier can reasonably provide it. For a remote project, age and storage matter, but that does not require a lab report for every filter.

The useful check is whether the filter part number, supersession or application record matches the machine serial or housing. A certificate for one filter batch does not prove that a different line item is from that batch.

Seals and hoses

For seals, request dimensions, material grade or material family, and batch or cure date if available. Ask whether the seals are sold as new, and how they have been stored.

For hydraulic hoses, ask for the assembly specification: length, end fitting types, pressure class and any assembly test evidence. If the supplier offers a test certificate, ask for the candidate number or assembly serial on the certificate.

A photo of a hose with a label is useful only if the label can be read and the candidate number matches the quotation line.

Undercarriage items

For new undercarriage parts, request the relevant dimensions such as pitch, pin diameter, bushing diameter and shoe width where applicable.

For used or take-off undercarriage parts, do not buy on good condition alone. Ask for written condition, measured wear limits, percentage remaining if the supplier uses that method, and the donor machine serial if known.

3. Keep identity, fitment, provenance, sample results and batch acceptance separate

One of the main mistakes is accepting a combined supplier statement that says genuine, fits, tested, good batch. Those are separate questions and need separate evidence.

Identity

Identity means the part number, old part number, dimensions or markings that identify what the part is. It does not prove where it came from.

Fitment

Fitment means the identified part is suitable for a specific machine or assembly. That is usually checked against a parts catalogue, engineering drawing or documented supersession.

Provenance

Provenance means the supply chain record. Ask for written evidence of origin or purchase trail only if provenance is important for the particular batch. A supplier statement is not the same as a traceable record.

Sample results and batch acceptance

Sample or test results apply only to the item or batch linked by the candidate number, batch number or serial. Ask which record belongs to which line item. If the supplier cannot link a certificate to the candidate number, treat it as missing evidence.

4. Put unresolved questions and written supply terms in the order

Remote Kazakhstan projects leave little room for back-and-forth after delivery. Ask unresolved questions before shipment and get the answers in dated written supply terms.

Questions to fix in writing

Ask whether a superseded or alternative part number may be supplied, and who approves that change.

Ask whether the batch may contain mixed production dates or old and new stock, and whether that is acceptable for the part type.

Ask what photos or records will be sent before dispatch, and whether each photo will show the candidate number and readable label.

Ask who is responsible if a part is unused but wrong or damaged at the remote site, and what written evidence is needed for a claim.

These are procurement terms, not technical tests. They should be dated and kept with the supplier’s quotation and delivery documents.

5. Next step: request an item-led evidence pack, not a general one

Ask the supplier to replace or supplement a general certificate file with an itemised evidence pack. The pack should show, for each line: candidate number, machine or assembly identity, old part number or relevant dimensions, condition, batch or serial where relevant, and the document name that supports each claim.

If a record is missing, ask for it instead of guessing. If the supplier cannot link a certificate to a physical item, that line is not ready for acceptance.

Parts matching support

MechLink is an external commercial parts information platform, not SANY’s official site, dealer, service centre, certifier or tester. It may help organise a single-item or batch candidate-number enquiry. If you use it, send the model and serial number, old part number, and component or housing photos with relevant labels or records. For current stock, price or delivery information, ask the supplier in writing; MechLink does not guarantee availability, authenticity, fitment, stock or delivery.
