"OEM" or "brand authorization" products refer to the licensor granting the use of the trademark or brand owned or represented by the licensor in the form of a contract to the licensee. The licensee conducts business activities in accordance with the provisions of the contract and pays the corresponding fees to the licensor.

There are many brand-authorized stores on e-commerce platforms. These stores are often named "xx flagship store" or "xx specialty store". They label the products as "authentic" on the details page to emphasize that the quality is guaranteed.

Brand authorization is also a new direction for some well-known brands to transform and layout in the e-commerce field. Taking Nanjiren as an example, the company has cut off the heavy asset links of production and sales, transformed into "Nanjiren e-commerce", and made profits through authorization. Search for "Nanjiren" on the e-commerce platform, and the products sold in the authorized stores include not only the clothes that Nanjiren relied on to start his business, but also bedding.
