If you are an Amazon seller and you urgently need a trademark for Amazon Brand Registry, then Germany is the best and quickest choice. Typically, trademarks are registered by the German trademark office within 3 to 4 weeks, in accelerated trademark application proceedings often in 2 to 3 weeks.

Additionally, a registered German trademark will allow you to enroll into Amazon Transparency program.  In Amazon’s own words “Transparency is a product serialization service that helps identify individual units and proactively prevent counterfeits from reaching customers. When you enroll in Transparency, Amazon scans your products to ensure that only authentic units are shipped to customers.”

Of course, filing in Germany is advisable as well if you sell your products in Germany or if you have a business in Germany.
