Stamped Part Containment Label and Sorting Evidence Guide

Short answer: Containment labels and sorting evidence matter when stamped parts are inspected, reworked, or temporarily released after a quality issue. The RFQ or corrective action plan should define defect criteria, sort method, accepted and rejected quantities, label wording, hold tags, photos, sample retention, inspector responsibility, report format, and when normal shipment labels can resume.

After a defect is found, the buyer often needs usable stock quickly. Sorting and containment can help, but only if the accepted parts are clearly labeled and the evidence shows what was checked. Otherwise receiving may not know whether a carton is normal production, sorted stock, reworked stock, or temporary approved stock.

Containment evidence to define

Separate sorted stock from normal stock

A containment action fails if sorted cartons look the same as normal production. Labels should show what was checked, who checked it, when it was checked, which lot or carton was included, and whether the stock is accepted, held, reworked, rejected, or released under deviation.

If a defect is visual, use photos or limit samples. If it is dimensional, use a gage or measurement rule. If it is functional, define the test. The label should not simply say inspected unless the inspection criteria and report are connected to the carton or lot.

Keep evidence tied to the buyer decision

Containment often happens under time pressure. The buyer may approve temporary shipment while root cause is still open. In that case, the label and report should show the temporary rule, expiry date, affected quantity, and whether future lots still need sorting. Use the first-off and last-off guide when the clean point depends on production lot release.

For mixed inventory, make the receiving path obvious. Sorted stock, unsorted stock, reworked stock, and deviation-approved stock should not share the same label or pallet position without clear separation. Connect labels to the carton label and barcode guide if receiving scans cartons into inventory.

RFQ details to include

• Defect description, affected feature, drawing revision, lot range, suspect quantity, current stock location, and buyer urgency.
• Pass/fail criteria: drawing limit, limit sample, photo standard, test method, gage, inspection lighting, magnification, or functional check.
• Sorting method, sample size or 100% sort rule, inspector qualification, rework rule, rejected-part handling, and second-check requirement.
• Label wording for sorted, held, rejected, reworked, deviation-approved, and normal stock; include date, lot, quantity, inspector, and report ID.
• Report format, photos, retained samples, accepted and rejected counts, clean-point rule, and containment exit condition.
• Shipment timing, replacement needs, line-down risk, annual volume, and whether buyer approval is required before sorted stock ships.

How to compare supplier answers

A useful answer gives a clear separation method and evidence package. A weak answer only says all stock will be inspected. Ask what label will be on the carton and what report receiving can use to release the parts.

If the issue affects function or safety, ask whether sorted stock needs buyer approval before shipment. Sorting can reduce risk, but it should not hide an unresolved process problem or ship parts outside the agreed acceptance rule.

Send defect photos, lot data, acceptance criteria, line urgency, and label expectations through the お問い合わせページ. Use the RFQ form to request containment labels and sorting evidence when a quality issue affects current supply.
