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

Ask for a line-by-line candidate-number evidence package, not one general quotation. For each part line request the machine model and suffix, machine serial number, old part number, component or housing photos, installation position, applicable catalogue revision, supplied condition, batch or lot trace, and any sample or inspection result that the supplier is actually relying on.

Model alone never confirms fitment, batch quality, or authenticity. A mixed batch multiplies the risk because several parts may look similar but come from different machines, revisions, conditions, or sources. Treat identity, fitment, provenance, sample results, and batch acceptance as separate questions.

1. Start with machine identity and fitment evidence

Machine model and suffix

Ask the supplier to list the SANY machine model and full suffix or configuration code for every part line. Similar model families can have different hydraulic, electrical, or undercarriage selections, so a part number that fits one suffix may not fit another.

Serial number and nameplate

Request the machine serial number and a readable nameplate photo. The serial number is stronger identification than the model because it ties the part to a specific production configuration.

Old part number and component photos

For replacement parts, ask for the old part number from the removed component, not only the new part number on the supplier's quote. Request photos of the old part from at least two angles, plus the housing or mounting area if the part is installed.

Installation position and catalogue revision

Ask which installation position the part belongs to, such as left or right, front or rear, boom or arm, or drive end. Also ask which SANY parts catalogue revision or applicable technical document the supplier used. A catalogue revision note helps show whether the part identification is current or superseded.

If any of these items is missing, request the missing evidence before accepting the line. Do not guess fitment from a model code alone.

2. Ask for a candidate number per part line

A mixed batch quote often groups many parts under one description. That is not enough. Ask the supplier to assign a unique candidate number to each physical part line, such as CAND-01, CAND-02, and so on.

Why the candidate number matters

The candidate number lets you keep identity, fitment, condition, provenance, and batch acceptance separate for each line. It also helps later inspection or returns without confusion.

MechLink, an external commercial support provider, may help organise single-item or batch candidate-number enquiries. If the discussion moves to supply, ask the supplier for current written stock and delivery information rather than relying on promised availability.

3. Confirm supplied condition and marking evidence

New, refurbished, or used

For each candidate line, ask the supplier to state the supplied condition in writing: new, surplus, reconditioned, used, or repaired. A mixed batch may contain different conditions, so one blanket word on the quotation is not enough.

Marking and label evidence

Ask for photos showing the part number, brand or maker mark, date code if present, and any production or batch code. A photo can support identification, but a photo or supplier statement is not proof of every claim. It should be checked against the catalogue revision and the old part.

Packaging and preservation

For sealed parts such as filters, seals, or electrical components, ask for a photo of the packaging label before opening. This is not a guarantee of internal condition, but it helps confirm the supplied identity and storage condition at the time of the photo.

4. Separate provenance, batch documents, and catalogue evidence

Provenance

Ask the supplier to provide the source or supply path of the parts, such as official dealer supply, previous project stock, surplus stock, or a named seller. Do not accept a general claim like 'original' without a document. If no source document is available, mark that line as unverified.

Batch or lot trace

Request any batch, lot, production, or invoice trace that links the candidate part to a specific supply event. This is especially important for filters, lubricants, seals, belts, and other age-sensitive items.

Catalogue revision and supersession

If the old part number has been superseded, ask for the supersession chain in the applicable parts catalogue or manufacturer document. Request the revision or date of the catalogue page. Where the supplier cannot show it, write down that the fitment remains unverified.

5. Keep sample results separate from full batch acceptance

Sample evidence

If the supplier offers a sample photo, test certificate, or inspection result, ask whether it belongs to the exact candidate line or to a representative sample. A sample result for one filter does not automatically prove the condition of all filters in the batch.

Batch acceptance

Before accepting the mixed batch, the responsible project or fleet manager should define acceptance criteria based on the applicable requirements. Evidence may include catalogue confirmation, old part number match, serial number match, marking check, and any agreed inspection result.

No acceptance decision should be made from a photo or supplier statement alone. The responsible parties decide acceptance after the evidence is assembled.

6. Parts Matching Support

If you need parts information or procurement clarification, prepare the machine model and suffix, machine serial number, old part number, component or housing photos, and relevant labels or records before you ask the supplier to verify a line.

MechLink can support organising single-item or batch candidate-number enquiries, but it is not a SANY official site, authorised dealer, service centre, manufacturer database, certification body, or testing platform. For parts information and procurement enquiries, the MechLink WhatsApp channel serving readers in this market is +77026412810. This is not a SANY official contact and does not imply a local office or local stock.

7. Missing evidence and procurement next step

For each missing item, ask the supplier to provide the specific document or photo before you accept that line. If the supplier cannot support a line, either remove it from the order, replace it with a line that has full identification, or record it as conditionally unverified.

The safest next step is to convert the quotation into a line-by-line evidence table using candidate numbers, then circulate that table to the responsible mechanic or fleet manager for review. Do not use model code alone to approve a mixed batch.
