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

Before paying, ask for a line-by-line evidence pack, not a general quotation. Each line should be tied to a machine or assembly identity, a candidate number, a supplied condition, a batch reference, and only the documents that are relevant to that part type. Then ask what is still unverified and put the open points into dated written supply terms.

1. Turn the quotation into line-item identities

Model and suffix are not enough

A model name or suffix alone does not confirm fitment. Different serial ranges, assembly updates and superseded designs can change the correct part even when the model looks the same.

Get serial number and old part number

Ask for the machine serial number, assembly nameplate, housing number where useful, and the old part number from the removed component. If the old part number is missing, request that missing evidence instead of guessing from memory.

Use component and housing photos

For a remote Kazakhstan site, clear photos of the old part, its label, the installation position and the surrounding housing can reduce the chance of a costly return. A photo supports identification, but it does not prove internal condition or fitment by itself.

2. Ask for candidate number and supplied condition for every line

Candidate number

A candidate number is an enquiry or quotation line identifier. It is not the same as a part number. It lets the seller link the quote line to the photo, document, package label or batch record for that exact item.

Supplied condition

Ask for a written statement of condition for each line: new, used, repaired, overhauled, old stock or dismantled. On a remote project, returns are slow and condition surprises are expensive, so condition must be stated before dispatch.

Batch references

Where applicable, ask for the lot, batch, production date or supplier batch reference. This helps separate one delivery from another and supports later traceability if a defect appears.

3. Match documents to the item, not the whole batch

The thick pack problem

A large PDF full of declarations or datasheets can look complete but still fail if the pages are not linked to a line item. Check that each relevant document carries the candidate number or part/assembly reference.

Not every item needs the same evidence. A filter media datasheet does not support a track shoe, and a hose pressure marking does not support a seal. Ask only for the evidence that the part type actually needs.

Filters

For filters, useful checks are the supplier or manufacturer technical data sheet linked to the candidate number, showing media type, micron rating or application if available. If the sheet is generic and has no line reference, mark it unverified.

Seals

For seals, useful checks are dimensions, material family, hardness if relevant, and a clear photo of the old part or housing. A written claim that it fits is not a dimension.

Hoses

For hoses, useful checks are installation position, end type, length, internal diameter, pressure rating if marked, and any hose marking or batch label. Ask for a photo of the marking rather than a summary statement.

Undercarriage items

For undercarriage parts, useful checks are part number, dimensions, wear state for used items, and clear photos of pins, bushings, links, shoes or other wear surfaces. Do not accept a model name as a condition report.

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

Why separation matters

A part may have the right number but not fit a later serial range. It may have a photo but no stated source. It may have a batch number but no acceptance decision. Do not merge these different questions.

Documented supersession

Where an old part number has been replaced, ask for documented supersession and catalogue revision or date. A seller’s note that the number changed is not enough.

A photo or supplier statement is not proof of every claim

A photo can show existence and some visible condition. It cannot prove material, internal quality, pressure rating, authenticity or hidden wear. Mark unsupported claims as unverified rather than treating them as confirmed.

Only responsible parties decide acceptance

The buyer or site engineer, using the applicable requirements, decides whether the evidence is acceptable. Do not ask the seller to self-certify a mixed batch without item-level records.

5. Put unresolved questions and dated written supply terms into the order

Unresolved questions

If the seller cannot confirm a serial range, batch reference, dimension or document link, record that as an open item. Decide whether that open item blocks payment, blocks dispatch, or must be resolved before the part is installed.

Dated written supply terms

Ask the supplier for current written stock and delivery information. Do not rely on a verbal lead time. Include in the written terms which evidence must be supplied before dispatch, which open items may stop acceptance, and what happens if documents do not arrive.

Procurement next step

Send one request for the whole mixed batch: for each line, provide machine or assembly identity, candidate number, supplied condition, batch reference, and relevant document or photo. Mark any missing evidence. Then compare the returned pack line by line, not as a single general file.
