Brand removed, lost edit rights – How do I rebrand 100+ EU ASINs to a new R-mark? (UK/Germany)

One more trick that worked for me: Buyer account brand registration. If your new trademark is the same (or super similar) to the old one, register it on a clean buyer account (no selling history, no performance issues). Then authorize your seller account to use it. This isolates your brand from your past seller account mess. It’s not a guarantee, but it saved me when my old account got flagged for brand abuse.

Risk warning—don’t try to change all 100+ ASINs. It’s not realistic. Half of them will fail, get stuck, or flag your account. Here’s what I did when I was in your shoes:
Pick your top 10-20 best-selling ASINs and focus on those. They’re the ones worth the effort.
For the rest? Create new ASINs under the new brand and redirect traffic—bundle them with your top sellers, add cross-sell links, or just let the old ASINs sell out.
Brute-forcing 100+ ASINs will only trigger more flags (brand abuse, listing violations) and put your new account at risk. Not worth it.

WEEE and EU Authorised Rep (for Germany)—let me break this down clearly:

• WEEE registration is tied to your brand. If you change the brand, your old WEEE number won’t work anymore. But you don’t need to re-register—ask your WEEE provider to add the new brand to your existing registration. It’s a small fee (usually €100-150), and you keep the same number. Skip this, and Amazon will reject your WEEE declaration and block your listings (speaking from experience).
• EU Authorised Rep is tied to your business entity (company name, address)—not the brand. As long as your legal info hasn’t changed, your existing rep is still valid. No need to get a new one just for a brand change.

Transparency program: Yes, you can enroll after the brand change! Transparency only cares that the ASIN’s brand name matches a registered trademark in Amazon’s system—category doesn’t matter. And it’s global—once you enroll an ASIN, it’s protected across all marketplaces.
Just fix the brand first, then enroll. Simple as that.

Changing brand on existing ASINs is a total nightmare, especially with 100+—trust me, I’ve been there. Here are the methods that actually work (from least to most risky, based on what I’ve tested):

Cross-marketplace sync (low risk, my go-to)

If you have access to a smaller marketplace (Canada, Mexico, Australia—doesn’t matter which), follow-on your ASINs there. The brand field is almost always unlocked on those smaller stores. Change the brand to your new one there, then sync it back to EU. Amazon shares catalog data across marketplaces, so this usually sticks.
How to do it (step-by-step):

• Go to the small marketplace, create a follow-on offer for the ASIN.
• Edit the listing—brand field should be editable.
• Change it to your new brand, save.
• Head back to EU, update the listing with the same new brand—it should go through without errors.

Open a case with Brand Registry (medium risk, but most compliant)
Grab clear photos of your product + packaging with the new brand logo (stickers are fine, no need for full rebranded packaging yet). Attach your new trademark certificate. Open a case via Brand Registry (https://brandregistry.amazon.com/cu/contact-us) and ask them to update the brand on your specific ASINs. Explain you legally rebranded and have proof. It might take 2-3 attempts (Amazon reps can be hit-or-miss), but it’s the only fully approved method.
Use a Vendor Central account (if you have access)
If you or someone you know has a VC account, they can edit ASINs directly—even without edit rights. If you hire a VC service, it’s expensive (especially for 100 ASINs), but it works. Only worth it for your top-selling ASINs, not the whole batch.
Heads up: Don’t waste time with the “OldBrand NewBrand” flat file trick—it’s been patched. Amazon flags it now, and you’ll just waste time.
