Restriction checker

You find a promising product, you’re ready to place the order, and then Seller Central tells you that you can’t actually list it. Restriction Checker in Tactical Arbitrage catches that problem before it costs you anything.

Paste up to 1,000 ASINs, UPCs, EANs, or GTINs (mixed formats all work together), and Restriction Checker runs the entire list against your connected Amazon account in one pass. Instead of checking products one at a time in Seller Central, you get a bulk eligibility report showing exactly what you’re cleared to sell right now.

This is most useful when you’re validating a sourcing list before you buy. Filter out restricted products first, then put your budget toward inventory you can list immediately.

Restriction Checker also works across marketplaces. If you sell on Amazon.com, Amazon.co.uk, and Amazon.ca, you can run eligibility checks for each one separately, since approval in one marketplace doesn’t guarantee approval in another.

One thing to keep in mind: Restriction Checker pulls from Amazon’s API. It’s highly accurate, but Seller Central’s Add Products page remains the official source of truth. If a result looks off, verify it there.

Find Restriction Checker under Analysis Tools in TA Classic, or under Tools in TA Lite.
