I am urgently requesting assistance regarding a recurring system-level technical issue with the "uk-18-knife" age verification attribute for our kitchen knife listings.

The Problem

Since July 10, we have received 74 duplicate performance notifications across 7 different ASINs, all alleging that our products lack the "uk-18-knife" attribute. Our products have been deactivated as a result.

We are fully aware of Amazon UK's requirements for selling kitchen knives:

*All products must be sold via FBA ✅

*The "uk-18-knife" flag must be uploaded via spreadsheet or product detail page ✅

We have complied with both requirements from day one.

What We Have Done (All Failed)

*Uploaded the product spreadsheet with full-update multiple times

*Edited each listing in "Manage All Inventory" and confirmed the age restriction setting

*Opened multiple support cases

*Submitted appeals via Account Health

*Each time we upload the spreadsheet, we receive additional performance notifications. The more we try to fix it, the more notifications we receive. We are stuck in a loop.

The Evidence That This Is a System Error:

For our older ASIN, the "uk-18-knife" flag is still visibly present on the front-end product detail page – yet the system continues to send notifications claiming it is missing.

For 3 of the new ASINs that have inventory in FBA, the flag is also present on the front end. For the other 3 new ASINs (currently in transit to FBA), we cannot observe the front end, but we have confirmed the attribute is correctly set in the backend.

This is NOT the first time. We experienced the identical issue in April–May 2026. After an extended process with Seller Support, the issue was eventually resolved manually..

Other sellers on this forum are reporting th exact same problem – the system fails to detect the "uk-18-knife" flag even when it has been correctly uploaded.

The Irony

Seller Support keeps instructing us to "upload the spreadsheet to update the uk-18-knife tag" – which we have already done multiple times. This is a circular response that does not address the underlying system failure.

Our Request:

*Review our case history and confirm this is a recurring system-level issue

*Escalate this matter to the technical team or internal review team – not to Seller Support (who keep giving us the same circular instructions)

*Help stop the repetitive automated notifications for these 7 ASINs

*Assist in manually restoring our products to active status

We are fully compliant sellers who have been selling kitchen knives on Amazon UK for a long time. This recurring system error is causing severe disruption to our business.

Any advice or guidance would be greatly appreciated!
