Cause: Missing or non-compliant main image (not pure white, <1000px, text overlay, AI-generated flagged), missing required attribute, or title violation.

Fix steps:

1. Go to Seller Central → Inventory → Manage Inventory → click the alert icon
2. Check the suppression reason. Fix the flagged attribute.
3. For image issues: replace main image — pure white RGB(255,255,255), product fills ≥85% frame, ≥1000px, no text/logos, no AI renders
4. For attribute issues: use a Flat File PartialUpdate with the corrected field
5. Allow 24–48hr for reinstatement after fix

Cause: ASIN blocked by Amazon policy (restricted category, safety concern, or prior suspension). Listing shows status "Inactive" with no Suppressed reason.

Fix steps:

1. Check the Performance notification for the blocking reason
2. Write a Plan of Action (POA): what happened, root cause, preventive steps
3. Open a case: Seller Support → Products → Account Suspension / Blocked ASINs
4. Attach POA + proof (invoices, certs, test reports if applicable)
5. If rejected: escalate to Account Health team

Cause: FBA inventory exists but no active listing to sell from. Usually caused by a listing being closed or removed after stock was shipped in.

Fix steps:

1. Seller Central → Inventory → Fix Stranded Inventory
2. Click "Relist" if the listing is salvageable
3. Or use Auto-Relist: Inventory → Settings → Auto-Relist Stranded Inventory → Enable
4. If ASIN doesn't appear in Relist options: create a new listing matching the ASIN and the inventory will link automatically

Cause: An attribute (title, brand, bullet, image) appears locked — flat file uploads silently fail to update it.

Fix steps (in order, escalate if each fails):

1. Brand Registry: use Manage → Update Listing to push the change through the registry
2. Flat File PartialUpdate: upload only the stuck field with the new value
3. Full Update: upload with all fields populated (overwrite everything)
4. Redrive: delete the ASIN (update-delete = Delete), wait 24hr, re-upload with full data
5. Case: if Redrive fails, open a case: "Attribute update not reflecting — requesting manual attribute update"

Cause: Parent-child relationship is broken — children show as standalone listings, or children are missing from the variation widget.

Fix steps:

1. Use Flat File Factory → Scenario B to rebuild the full variation family in one file
2. Include parent row + all existing children + any new children
3. Set update-delete = PartialUpdate for parent, PartialUpdate for all children
4. Ensure variation-theme is identical across all rows
5. Upload. Amazon reconciles the family within 15–30 min.

Cause: Price is above Amazon's "fair price" threshold, or account health score is too low to win Buy Box.

Fix steps:

1. Check: Seller Central → Pricing → Fix Price Alerts
2. Lower price to within the Amazon reference price range, or
3. Check Account Health: Seller Central → Performance → Account Health. If below threshold, address open cases first.
4. Note: Buy Box returns within a few hours once price is fixed

Cause: Third-party seller listing counterfeit or unauthorised products on our ASIN and winning the Buy Box.

Fix steps:

1. Document: screenshot the seller, their price, and their offer
2. Send a Cease & Desist to the seller via Seller Central messaging
3. Report via Brand Registry: Protect → Report a violation → Counterfeit/Unauthorised
4. Do a test buy to gather evidence (receipt + the actual product received)
5. If still ongoing: escalate via Brand Registry case with test buy proof

Cause: Amazon has deactivated the ASIN due to safety, compliance, or policy concerns. This is more severe than "Blocked".

Fix steps:

1. Read the deactivation notice carefully — it will name the specific regulation or policy
2. Gather required documentation (test reports, certifications, invoices)
3. Write a POA addressing the specific concern
4. Open case via Account Health: "ASIN Deactivation Appeal"
5. Upload all documentation in the case
6. If rejected: request escalation to Account Health specialist

Cause: Amazon merged our ASIN with a different product, or created a duplicate ASIN that splits reviews and traffic.

Fix steps:

1. Open a case: Seller Support → Products → Report a Product Page Issue
2. State: "These ASINs were incorrectly merged. They are distinct products." Include both ASINs, product titles, UPCs, and photos proving they are different products.
3. For duplicates: request the incorrect ASIN be retired and traffic/reviews merged to the canonical ASIN

Cause: Amazon requires certification, safety test report, or regulatory document for the product category (children's products, food/supplements, electronics, etc.)

Fix steps:

1. Read the compliance notice — it names the specific requirement (CPSC, ASTM, FDA, etc.)
2. Obtain the required document (test house, certifier, or internal quality team)
3. Submit via Seller Central → Account Health → Manage Compliance Documents, or via the specific case
4. Processing: typically 7–14 days after document submission
