Raw material stock is easier to assess when each physical group has a traceable specification and a clear quantity basis. A handwritten grade on a rack is a lead to investigate, not the same evidence as a document matched to the material.
Keep identity, condition and quantity separate. Even well-documented material may have storage damage or dimensions that need checking.
Create one record for each meaningful material lot
| Field | What to record |
|---|---|
| Material identity | Product or grade exactly as supported |
| Form and dimensions | Sheet, bar, tube, reel or other form; stated units |
| Batch or heat reference | Marking and document link where applicable |
| Quantity | Count, measured dimensions or weighed quantity with basis |
| Certificate | Issuer, reference and evidence connecting it to the goods |
| Condition | Corrosion, contamination, deformation or other observations |
| Storage | Location and relevant known history |
| Unknowns | Unverified grade, missing identity or uncertain mixed material |
| Release | Ownership, retained quantity and approved lot |
Do not claim a particular grade from colour, weight or a spark test performed without an appropriate method and competence. If specification evidence is missing, record the uncertainty.
Check the certificate belongs to the stock
Match the document's identifiers to markings and supply records. Preserve the original references through sorting and repacking.
The batch traceability guide explains how to keep product identifiers connected when a commercial lot is split. A certificate for one heat or batch should not be used to support unrelated material simply because it is stored alongside it.
If the document uses units or product descriptions unfamiliar to the team, obtain clarification rather than simplify them into a different specification.
Describe the quantity without overstating precision
State whether weight comes from a dated weighing record, a supplier label or an estimate. Record whether packaging or supports are included in the figure.
For lengths or sheets, count items and record the measurement basis. A nominal purchased dimension may differ from a remnant's present usable size.
The offcuts and remnants guide covers irregular pieces and mixed sizes. Keep those separate from full-length stock unless the catalogue clearly identifies the difference.
Review handling and material-specific information
Heavy material needs appropriate storage and handling arrangements. HSE's warehouse guidance provides the general context for safe access and movement. Do not rearrange unsupported stock merely to obtain a better photograph or count.
If the material is a chemical or has relevant hazard information, retain the correct safety data sheet and obtain appropriate advice. The sheet supports handling and hazard decisions; it is not a substitute for a quality certificate.
Use the pallet and stillage guide to establish whether the supports belong to the seller and form part of the lot. A returnable stillage can create a separate ownership issue even where the material itself is available.
Make the buyer's evidence easy to follow
Photograph the physical group, identifying marks and material condition. Refer to the document by a stable record number. Keep private supplier pricing separate from specification evidence.
Send UK Auction Group the material-lot records and certificate links. Flag unverified groups before discussing the sale route. A precise statement of what is established is more useful than an attractive grade claim the documents cannot support.
