If this is possible, would there be any difference between connecting a UAE trademark and a US trademark to Amazon Brand Registry for selling in the US? Are there any advantages, disadvantages, or limitations I should be aware of when using a UAE trademark?
Yes, you can generally enroll in Amazon Brand Registry using a UAE trademark; the trademark doesn’t necessarily have to be registered in the US.
For selling in the US, the main difference is that your trademark rights are territorial. A UAE trademark protects you in the UAE, not the US. So if you plan to build a long-term brand in the US, a US trademark is usually preferable for stronger US legal protection and enforcement.
Amazon Brand Registry features may be available with either, but trademark-specific legal protection will depend on where the trademark is registered.
