Batch numbers and traceability in surplus stock sales

A sale lot number and a product batch number serve different purposes. The lot identifies the commercial package. The batch or serial reference connects the goods to manufacturing and supply records.
Keep both. Replacing original identification with an auction sticker can break the link a buyer needs for a recall, specification or later enquiry.
Build a batch-to-lot cross-reference
Use a row for each batch within each sale lot.
| Sale lot | Product reference | Batch or serial range | Quantity basis | Supporting document | Physical location |
|---|---|---|---|---|---|
| Enter lot | Actual identity | Exact readable reference | Counted or labelled basis | Invoice, certificate or other record | Pallet or bin reference |
| Same lot, next batch | Actual identity | Separate batch | Separate quantity | Relevant document | Identified section |
Leave an unreadable reference unresolved. Do not infer a batch from another package in the same area without evidence.
The surplus catalogue guide shows how to present useful information to buyers. Keep confidential commercial details controlled while supplying the product evidence needed for the transaction.
Follow the stock when a lot is split
Suppose a fictional batch occupies six cartons and is divided into two lots. The cross-reference should show which cartons and quantity went into each lot. It should not simply retain one row saying the batch was sold somewhere in the project.
If a sale lot combines several batches, preserve those distinctions. One batch may have a different date, specification or safety notice.
Photograph labels before packaging is separated from contents. Where repacking is appropriate, carry forward identification through a controlled process. Do not create a label that looks like a manufacturer's original when it is a seller's internal reference.
Keep documents tied to actual goods
Check that a certificate or specification document names the relevant material, product or batch. A folder from the same supplier is not necessarily evidence for every item in the store.
If the link cannot be established, describe the document as unconfirmed rather than claim certified stock. Ask the supplier or appropriate specialist what further evidence is available.
The uncertain-origin guide addresses gaps in authenticity or provenance. Traceability supports that investigation, but a batch number printed on a label does not independently authenticate the product.
Use the record for safety checks
The recall screening guide depends on exact identifiers. A notice may concern a limited batch or serial range, so retaining that information can materially change the hold decision.
Government product-safety guidance explains supplier-traceability responsibilities for consumer products. Product-specific rules and Great Britain or Northern Ireland requirements may add detail. This worksheet supports the record; it does not replace those duties.
Do not publish a broad "recall checked" statement without the search date, source and matching basis in the controlled file.
Reconcile documents at collection
Prepare a handover list naming the documents supplied with each lot. Check that the collected goods still match the lot and batch schedule after any sorting or quantity changes.
Record exclusions and missing evidence before release. A buyer receiving a certificate for a different batch has not received the promised support, even if the product descriptions look alike.
Give UK Auction Group the cross-reference sheet and document list. That lets the sale preserve the goods' identity from catalogue preparation through collection and later enquiries.
