> ASINs at risk of losing the Prime badge - sortable table with current OTD vs SFP threshold. Each row = a Buy Box loss waiting to happen.

## At a glance

> Per-ASIN view of Prime-promised on-time delivery rate, joined to Amazon listing data. Each row is one ASIN with current 30-day Prime OTD; sorted ascending so worst-performing rises to top. Rows below 99% are at SFP eligibility risk; rows below 96% are likely candidates for badge revocation. The card is the per-product diagnostic that goes underneath the seller-account-wide SFP eligibility number.

|                              |                                                                                                                                                                                                                                                                                                      |
| ---------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **What it counts**           | `GROUP BY amazon_prime_shipping.shipment.asin COMPUTE otd_pct WHERE otd_pct < 99 JOIN amazon.listing ON asin` over rolling 30 days. ASINs with sufficient sample (typically >20 shipments in 30D) included; low-volume ASINs filtered out for noise.                                                 |
| **Required Amazon sibling**  | `has_amazon_sibling`. Card requires an Amazon connector (Seller Central or Vendor Central) for the listing-side data join.                                                                                                                                                                           |
| **Why ASIN-level matters**   | Amazon's SFP eligibility scoring is at the seller-account level, but listing-level performance varies materially. A heavy SKU shipping from a single warehouse to East Coast may run 99.5%; a rural-customer-skewed SKU may run 96%. Account-wide dilution masks this; the per-ASIN view exposes it. |
| **Buy Box loss correlation** | Below 99% Prime OTD on an ASIN, Amazon's Buy Box algorithm starts deprioritising the listing within 7 to 14 days. Each ASIN row in the table is a future Buy Box loss; the card surfaces them before the loss happens.                                                                               |
| **Service level scope**      | Prime-eligible 1-Day / 2-Day / Same-Day.                                                                                                                                                                                                                                                             |
| **Time window**              | `30D`                                                                                                                                                                                                                                                                                                |
| **Alert trigger**            | `any ASIN <99% OTD`. Card alerts on the existence of any below-threshold ASIN; the table content is the diagnostic.                                                                                                                                                                                  |
| **Roles**                    | owner, operations, marketing                                                                                                                                                                                                                                                                         |

## Calculation

Calculated automatically from your Amazon Prime Shipping (SFP) data. See the At a glance summary above for what the metric tracks and the worked example below for a typical reading.

## Worked example

A US small-appliance merchant. Reading at 09:00 ET on 12 Mar 26 for the trailing 30 days.

| ASIN                              | Listing               | Prime shipments (30D) | Prime OTD | Buy Box risk                                                                          |

| B08DEF9012                        | Stand mixer, \$189    | 145                   | **97.1%** | Medium - on warning list                                                              |
| B07GHI3456                        | Hand mixer, \$45      | 510                   | 98.9%     | Medium - just below 99%                                                               |
| B07JKL7890                        | Food scale, \$25      | 720                   | 99.4%     | OK                                                                                    |
| (38 ASINs above 99% OTD, omitted) |                       |                       |           | OK                                                                                    |

Account-wide Prime OTD: 96.3% (matches `amazon_prime_sfp_otd_sla`). Five things to notice:

1. **Two ASINs (B07XYZ1234 and B07ABC5678) account for \~70% of the seller-account-wide miss volume.** Concentration matters: fixing two SKUs lifts the whole account toward 99%.
2. **Both worst-performing ASINs share the rural-USPS-Priority cohort.** The fix is product-level: opt these ASINs out of Prime eligibility for rural ZIPs (in Seller Central → ASIN-level Prime settings if available, or globally for the seller account). Customers in those ZIPs see the listing without Prime; conversion drops on those orders but the account-wide Prime badge is preserved.
3. **B08DEF9012 (stand mixer) at 97.1% is the medium-risk SKU.** Larger / heavier items run higher exception rates and are more carrier-mis-handled. Consider double-walled packaging or signature-required upgrades for this cohort.
4. **B07GHI3456 (hand mixer) at 98.9% is on the cusp.** One bad week pushes it below 99%; pre-emptive monitoring required.
5. **The 38 ASINs above 99% are doing fine.** Account-wide remediation should focus on the 4 problematic ASINs, not blanket-tighten all SKUs. The card surfaces the actionable cohort.

## Reconciling against the vendor's own dashboard

**Where to look in Amazon Seller Central:**

Seller Central does not natively offer per-ASIN Prime OTD breakdown in a single dashboard view. Closest: **Performance → Shipping Performance**, drill into individual ASINs via the order-history reports. Most sellers manually export and pivot in spreadsheets. This card is the automated equivalent.

**Why our number may legitimately differ:**

| Reason                          | Direction            | Why                                                                                                                     |

| **Listing-data join freshness** | Ours \<1 hour behind | Amazon listing data refreshes hourly via SP-API.                                                                        |

## Known limitations / merchant FAQs

**Why ASIN-level when Amazon scores at the seller-account level?**
Account-wide eligibility is the consequence; ASIN-level Prime performance is the cause. Two ASINs running 90% can drag a 50-ASIN seller account from 99% to 96%. Fixing those two specific ASINs is much cheaper than blanket-tightening operations across all 50.

**The card shows 4 ASINs at risk; which do we fix first?**
Sort by total Prime miss volume (Prime shipments × (1 - Prime OTD)). The ASIN contributing the most absolute miss volume gives the largest account-wide lift when fixed. The card sorts by OTD% ascending; for triage purposes, look at the volume column too.

**ASIN-level Prime opt-out: how does it work?**
Amazon's Prime settings allow account-wide opt-out of specific ZIPs. ASIN-level opt-out is more limited but exists for some categories. Check Seller Central → Account Info → Prime Settings → Excluded ZIP Codes, and combine with Inventory → Edit Listing → Prime Eligibility for the per-ASIN view where supported.

**Low-volume ASINs are filtered; can we see them?**
Yes by lowering the volume threshold in card settings. Default is >20 30D shipments; lowering to >5 surfaces more ASINs but introduces noise from small-sample variance.

**An ASIN at 99.5% just dropped to 96%; what happened?**
Three usual causes. (1) Carrier-mix shift for that ASIN: Amazon rerouted some volume to a different carrier for capacity reasons. (2) Demand shift to rural ZIPs: a regional promotion or marketplace expansion brought in customers from longer-zone destinations. (3) Packaging change: new packaging trim weight or dimension shifts ZIP-rate-card categorisation. Investigate by comparing this period's destination ZIP profile to last period's.

**Buy with Prime ASINs: are they here too?**
Yes if the Buy with Prime program is connected. Buy with Prime products are tracked separately but pooled into the per-ASIN Prime OTD computation.

**Does this card include FBA orders?**
No. FBA-fulfilled orders are managed by Amazon and don't appear in SFP eligibility scoring. This card is SFP-only (and Buy with Prime where connected).

**A new ASIN was launched mid-period; weighting?**
ASIN appears in the table once it has >20 30D shipments. New launches with smaller initial volume may be filtered out for the first few weeks. Track separately during launch ramp.

**Amazon's per-ASIN Prime OTD: does Amazon expose this in the API?**
Limited. Amazon's SP-API exposes per-order delivery data; the per-ASIN aggregation is the merchant's responsibility (or Vortex IQ's, in this card). Amazon's seller-facing reports include some per-ASIN delivery metrics but not in a real-time dashboard format.

**During Q4 peak, every ASIN dips; do we triage?**
Focus on the highest-volume ASINs (the SKUs that dominate revenue). A 95% Prime OTD on a 1,000-shipment-month SKU is more impactful to account-wide eligibility than 95% on a 50-shipment-month SKU. Sort by absolute miss volume (column not shown in worked example but in card UI).
