Where do hijackers get the inventory to sell?
Practitioner reports across Reddit and seller communities commonly trace private label hijacker situations back to one of three sources:
Leaked factory inventory. Practitioner-reported cases commonly describe Chinese manufacturers retaining production overrun, seconds, sample runs, or cancelled-order inventory, then selling it directly or through a local distributor or broker. In some cases, the units may have been made to your spec, which can make them harder to distinguish from your intended inventory and easier to list against your ASIN. This is a practitioner-reported risk pattern, not a universally documented default.
Unauthorized reseller arbitrage. Someone bought your product in a retail channel, such as Walmart, a liquidator, or another Amazon account, and is reselling it on your ASIN. This is often lawful under first-sale doctrine, but they may be selling damaged units, returns, or product that should not be in any retail channel.
Counterfeit production. A separate factory produces a near-clone and lists it on your ASIN. This usually requires a test buy to confirm. The product will often fail at the test buy: wrong labeling, different packaging, different feel.
Brand Registry may help remove listings tied to all three scenarios, depending on the evidence and policy fit. The supply chain controls below are designed to reduce the first two, which practitioners often report as the more common cases.
What is the Octo Hijacker Prevention Stack — 5 supply chain controls?
| Control | What it does | How to implement |
|---|---|---|
| 1. Overrun clause in manufacturing contract | Restricts the factory from producing, selling, or holding inventory above the contracted order quantity. | Add a contractual clause: "Manufacturer shall not produce units in excess of the Purchase Order quantity without written authorization. All excess units are property of the Buyer." Enforce with a post-production unit count audit. |
| 2. Unique product identifiers beyond ASIN | Makes counterfeiting and unauthorized resale harder to pass off as the real product. | Add a QR code, hologram sticker, or batch number to the packaging that links to a verification page. Your product detail page can reference these identifiers in the product description or A+ content where applicable. |
| 3. Controlled downstream distribution | Limits who can buy your product in volume for resale. | Do not sell to wholesale buyers who do not agree to your resale terms in writing. If you sell on your own DTC site, do not offer bulk discounts without distributor agreements. |
| 4. Quarterly factory audit for production records | Catches overrun production before it reaches a broker. | Ask your factory for production records per order: total units produced, units shipped to your FBA, units retained, which should be zero. Request this as part of every final payment. |
| 5. Test buy + cease-and-desist cycle, proactively | Establishes your documentation before a hijacker is active. | Buy 1 unit from any new seller that appears on your ASIN within 30 days of listing. If the product matches, document it. If it is counterfeit, you have a test buy on file and can escalate immediately. |
Quick red flags to check:
- A new seller appears on your ASIN within 30 days of a restock
- Your factory will not provide post-production unit counts
- Bulk buyers want volume pricing without resale terms
- Returned or damaged units are showing up in secondary channels
- Test-buy units arrive with packaging or labeling differences
Why is Brand Registry slow, and what can you do during the wait?
Brand Registry's violation process requires Amazon to verify ownership and assess the reported violation before taking action. Seller reports suggest review times can vary widely, and some cases appear to take around 5–14 business days, especially when the first submission is incomplete. Timelines can also differ by violation type and evidence quality.
During the wait, three actions may reduce buy box loss:
- Lower your price to win back the buy box. An unauthorized seller on your ASIN often cannot sustain a lower price indefinitely because they are reselling, not manufacturing. Matching or slightly undercutting their price can help you win the buy box back during the removal process.
- Run a Sponsored Products campaign. Sponsored placements are yours when you are the sponsored seller. While the organic buy box is contested, sponsored placement can help protect conversion volume.
- Submit a test buy invoice to Brand Registry as supplemental evidence. If you have purchased the seller's unit and it does not match your product spec, such as wrong packaging, wrong labeling, or wrong color, that documentation may strengthen the report and can improve the odds of a faster review in some cases.

What would Octo SAM do?
Octo methodology: SAM treats overrun control as a standard sourcing control, not a reactive legal add-on. In practice, that means including overrun clause language in manufacturing contracts and requesting post-production unit count records as part of delivery documentation. The goal is simple: close a commonly practitioner-reported hijacker origin point before the first order ships.

Frequently Asked Questions
My manufacturer says they'll destroy overrun inventory. How do I verify this? Seller reports from the FBA community suggest a factory destruction certificate and a witnessed destruction process, such as photos, video, or a third-party inspector, is a common request for high-risk products. For lower-risk products, a contractual overrun clause plus a unit count audit at delivery may be sufficient. A factory that refuses to provide a post-production unit count is a risk signal.
Can I trademark my packaging to prevent counterfeit listings? In practice, Amazon Brand Registry eligibility is generally tied to an active registered trademark for your brand, not packaging alone. A trademark on your brand name or logo may support Brand Registry access and gives you access to Amazon's IP reporting tools, subject to Amazon's current requirements and review. The trademark itself does not prevent counterfeiting. It may improve your ability to report counterfeit listings. Unique packaging identifiers, such as holograms, batch numbers, and QR codes, add a physical detection layer that trademark protection alone does not provide.
Is it legal for my factory to sell my private label product without my permission? That depends on the contract, the jurisdiction, and the facts of the sale. If your manufacturing agreement includes exclusivity, IP ownership, confidentiality, or overrun restrictions, unauthorized sales may create a stronger contract claim. Without those terms, the analysis can be less clear. This is not legal advice. Review your specific contract with a qualified attorney if you have an active dispute with a manufacturer.
