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

Before buying a mixed batch of SANY spare parts for a remote Kazakhstan project, ask for a line-by-line pre-purchase evidence pack. Each order line should have its own candidate number and be tied to machine or assembly identity, supplied condition, batch reference and only the dimension, material or test records relevant to that item. Do not accept a model number alone as proof of fitment, batch quality or authenticity.

A candidate number is a temporary line identifier you and the supplier use to trace each offered part through photos, quotes, labels and records.

1. Build the request around each order line, not a single quote

A mixed batch can combine different machines, revisions and conditions. Ask the supplier to number each line in the quotation and keep that candidate number on every photo, label, dimension sheet, batch record and test document.

Machine and assembly identity

For each line ask for:

• machine model and full suffix or series;
• serial number or product identification number where available;
• nameplate photo for the machine or major assembly;
• old part number from the removed part;
• component or housing photo;
• installation position.

These are identification inputs, not acceptance proof. They help you and the supplier test whether the offered number lines up with the specific machine.

Old part number, supersession and catalogue revision

Model alone never confirms fitment, because a machine series may have running changes. Ask which parts catalogue revision was used and whether the part number is current, superseded or substituted.

If the offered number is not the same as the old part number, ask for the documented supersession or substitution chain. If that chain is not available, record it as an unresolved question and request the missing evidence instead of guessing.

2. Separate identity, fitment, provenance and batch acceptance

A thick document pack can still fail if the records are not tied to each offered line. Keep these claims separate:

• identity: what the item is;
• fitment: whether it matches the machine or assembly;
• provenance: where the item came from and its supplied condition;
• sample or test results: whether a material or performance record belongs to that batch;
• batch acceptance: whether the buyer or engineer accepts the batch for the project.

Identity vs fitment

A clear photo can support identity but is not by itself fitment proof. A supplier statement that a part fits is also not proof unless it is backed by the applicable catalogue, drawing, dimension check or written confirmation the buyer can verify.

Supplied condition and batch references

Ask whether each line is new, unused old stock, used or reconditioned. Request batch, lot, date or serial references where present. For mixed batches, condition should be line-level, not a general phrase for the whole quote.

Document pack versus item-to-record link

Before accepting a certificate folder, ask: “Which line number does this record belong to?” If the answer is not traceable, treat the record as supporting information only, not batch-specific evidence.

3. Apply commodity-specific checks only when they change the decision

Not every item needs the same evidence. The useful question is what changes acceptance for that commodity in a remote project.

Filters

For filters, the practical checks are:

• thread or seat form and seal dimensions;
• bypass valve setting only if the fitment or application depends on it;
• date or batch marking and manufacturer marking;
• condition of packaging and any supplied batch record.

A filter does not always need an independent laboratory report. But if the filter is critical or suspected old stock, ask for a batch link to the supplier’s written record.

Seals and hoses

For seals, ask for material, hardness where relevant, and dimensions or part-number-to-application match. For hoses, ask for dash size, working pressure class, end fittings and date or batch marking. Old stored hose can be a risk for remote-site replacement, so date or storage evidence may matter more than a generic certificate.

Undercarriage items

For track shoes, pins, bushings or related undercarriage parts, ask for pitch, bushing or pin dimensions and, where relevant, hardness or wear state. New part numbers alone can mislead if the existing undercarriage is worn or if the mixed batch contains used parts. Dimensional checks should be line-specific when the batch is mixed.

For items outside these groups, still apply the same core request: line-level identity, candidate number, condition, batch reference and the minimum relevant record needed to verify fitment.

4. Keep unresolved questions visible

A missing answer should not become an assumption. Keep a short written list of unresolved questions, such as:

• exact catalogue revision not confirmed;
• supersession chain not documented;
• mixed new and used condition not assigned by line;
• batch number present on the part but not linked in the supplier’s record;
• dimension or material record not traceable to the offered line;
• test or certificate supplied but not item-specific.

The responsible party for acceptance is the buyer or project engineer using the applicable machine requirements, not the supplier’s sales description. A supplier statement is useful, but it is not the same as a checkable record.

5. Put the supply terms in dated written form

Ask for a dated written offer that states candidate numbers, supplied condition, batch references and the records the supplier will provide. Also ask for current written stock and delivery information for the batch. Do not treat that as a promise of availability or a guaranteed lead time; it is a procurement input for your own planning.

If a question remains open, request the missing evidence before acceptance. That is better than waiting until the parts arrive at a remote site.

Parts Matching Support

To prepare a mixed-batch enquiry, provide model and serial number, old part number, component or housing photos, and any label or record. Independent parts-matching support may help organise a candidate-number request through MechLink, a commercial third-party service; it is not the acceptance authority and does not guarantee fitment, authenticity, stock, price or delivery.
