If you’re a reseller looking to dive into the booming world of K-beauty on Amazon, you’re not alone.
The global demand for Korean skincare and cosmetics has skyrocketed, and Amazon is one of the most popular platforms for resellers to reach a wide audience.
However, before you start listing your products, there’s a critical requirement you need to be aware of: Letter of Authorization (LOA).
At SEOUL4PM, we work closely with resellers like you to provide high-quality K-beauty products in bulk. But we also want to ensure you’re well-informed about the challenges and requirements of selling on Amazon, especially when it comes to brand authorization. Let’s break down what you need to know about LOAs and why they matter.
An LOA is a document issued by a brand owner that grants a reseller permission to sell their products on Amazon.
It’s essentially a way for brands to protect their intellectual property, maintain control over their distribution channels, and ensure that only authorized sellers are listing their products.
Amazon requires this document to verify that resellers are legitimate and not selling counterfeit or unauthorized goods. Without an LOA, your account could face suspension, or your listings could be removed.
Here’s the catch: many K-beauty brand owners already operate their own Amazon stores or have exclusive agreements with specific distributors.
This means they are often unable or unwilling to issue LOAs to third-party resellers.
Recently, as K-beauty has gained global popularity, many brands have begun to enter Amazon directly. As a result, an increasing number of products are no longer eligible for sale on Amazon.
As a long-term solution, consider building your own direct-to-consumer channel using platforms like Shopify, rather than relying solely on Amazon.
As a distributor, we source our products directly from brands or authorized suppliers, but that doesn’t automatically grant us the authority to issue LOAs on behalf of the brands. While we can provide you with authentic products, the responsibility of obtaining an LOA falls on you as the reseller.
If you’re new to selling K-beauty on Amazon, this can be a frustrating roadblock.
Many resellers are unaware of this requirement until they’ve already invested in inventory and started listing products.
Unfortunately, without an LOA, you risk:
What’s more, the environment is becoming increasingly competitive. Recently, there have been cases where resellers report each other to Amazon, claiming counterfeit sales—even when the products are genuine. This kind of internal competition only makes it harder to maintain stable operations without proper brand authorization and documentation.
In the long term, Amazon is likely to shift toward a model where K-beauty brands enter the platform directly. That’s why diversifying sales channels is becoming increasingly important. Even if a Letter of Authorization (LoA) is issued now, there’s still a high possibility that the brand may suddenly revoke or stop authorizing the LoA in the future.
Selling K-beauty on Amazon can be a lucrative venture, but it’s essential to understand the platform’s requirements and limitations. The Letter of Authorization is a critical piece of the puzzle, and failing to secure one can lead to significant setbacks for your business.
By doing your due diligence, diversifying your sales channels, and focusing on reseller-friendly brands, you can build a sustainable and successful K-beauty business.
