Release or Disposal
Follow your own part control and scrap procedures. Mutilate scrapped parts so they cannot re-enter the supply chain, where your procedure requires it.
Quarantine stock visibility
Optional review of quarantine status and aging reporting in your ERP.
Optional. The tool and every export work without this. No spam.
How to use the tag
Print one tag for each affected item. Enter the tag number, status, part and serial details, the reason and where it is stored. Attach the tag to the part and keep a copy with the quarantine log. When the required action is done, record it in the tag log, sign the release or disposal block and update the stock status in your ERP so the item cannot be issued by mistake. Export to PDF for printing or Word for a custom layout.
Which status to use
Choose the status that tells the next person what they may do. Unserviceable means known not fit for use. Suspect means unknown pedigree or condition. Quarantine is a hold pending decision.
- Unserviceable: repair or scrap
- Suspect: investigate origin before any use
- Quarantine: segregated, no issue until released
- Scrap: authorize, record, then mutilate if required
Common mistakes
The classic mistake is tagging the part but leaving the ERP stock status as available, so the pick list still offers it. Another is writing a vague reason such as 'bad', which delays the decision. Keep quarantine areas physically separate and access controlled. Review open tags weekly; items with no owner or date quietly accumulate. If you suspect an unapproved part, follow your reporting process and your authority's rules rather than handling it informally.
Frequently Asked Questions
Does a tag replace an ERP status change?
No. Both are needed. The tag controls the physical part and the ERP status prevents the system from offering it for issue.
How long can a part stay in quarantine?
Set your own review time in the procedure. Many shops review weekly so items do not age without a decision, and escalate anything older.
Who authorizes scrap?
Your procedure decides, usually quality or an authorized person. Record the authorizer and mutilate the part where required so it cannot return to service.
Can I use this for customer-owned parts?
Yes, with a customer notification step. Owner approval is often needed before scrapping or returning customer property.
If quarantine stock is only tracked on paper, we can help reflect the status in your ERP and add an aging report.
