Product diversion—the unauthorized sale of genuine products outside intended channels—costs brands millions in lost revenue, pricing power, and partner trust. Tracking and stopping diversion is critical for protecting your brand’s value, especially on marketplaces like Amazon.

Here’s how to identify, trace, and act on product diversion.
1. Start with Strong Sales Vetting and Onboarding
Prevention is easier than enforcement.
- Carefully vet new distributors and retailers before onboarding.
- Watch for red flags: extra large or unusual orders, inconsistent PO activity, or weak business backgrounds.
- Require written agreement to your MAP, marketplace, and diversion policies.
Note: This step sets the foundation for all effective tracking and enforcement. It also helps prevent the issues explained in what causes product diversion.
2. Implement Serialization or Lot/Batch Tracking
- Serialization: Assign unique codes or serial numbers to each product unit or batch.
- Lot Codes: Mark every shipment or batch with traceable information (lot code, date, destination).
This enables you to trace any product found on unauthorized channels back to the original buyer or shipment.
3. Maintain Detailed Sales and Shipping Records
- Record every shipment—recipient, date, PO, quantity, and any identifying codes.
- Make it easy to cross-reference products found in the wild with your records.
4. Conduct Regular Test Buys
- Purchase your product from unauthorized Amazon sellers, grey market retailers, or suspicious websites.
- Document the seller, listing, product condition, and capture any unique serial or lot numbers.
Test buys are often one of the clearest ways to connect a marketplace seller back to a source. See Amazon test buys.
5. Analyze Return, Overstock, and Liquidation Channels
- Review patterns of returned or overstocked inventory—these often end up in grey market or unauthorized hands.
- Audit liquidators and “closeout” buyers carefully. Document all transactions for traceability.
6. Use MAP Monitoring and Channel Surveillance Tools
- Deploy MAP monitoring software to catch pricing violations and identify new unauthorized sellers the moment they appear.
- Use distribution monitoring services to watch for leaks and unauthorized listings across major marketplaces.
MAP violations often reveal deeper diversion patterns. Learn more about using MAP pricing, MAP monitoring software, and MAP enforcement software.
7. Audit Distribution Partners and Conduct Surprise Checks
- Periodically audit your authorized partners, especially if you notice patterns of diversion.
- Conduct surprise inventory checks, request detailed sales reports, and investigate anomalies.
This is especially important in exclusive distributor or selective distribution models, where one leak can undermine the whole structure.
8. Act Fast on Evidence
- When you identify diversion, use your records and serial data to confront the source.
- Enforce your agreements—send cease & desist letters, apply contractual penalties, or terminate supply as needed.
If diverted product is already appearing online, brands may also need to remove unauthorized sellers while addressing the source of the leak.
Final Thought
Tracking product diversion requires proactive onboarding, robust record-keeping, regular market surveillance, and the discipline to act quickly when you discover leaks.
Brands that invest in these controls are best equipped to protect their pricing, preserve channel integrity, and stop unauthorized Amazon sales.
