In the Add a Product tool, choosing the best category ensures that you see the most appropriate data fields for your product. Find your product’s best category using the Find your products in Amazon's catalog search box or browse the categories directly, by clicking the links, to choose one on your own.
If you are not sure of your product's category, the search tool is a quick and useful option. In the box, type a few simple product keywords. It is often best to choose the most basic keywords from the product's name, such as "baseball glove" or "evening gown."
The results page suggests a list of categories on the right, and, on the left side, displays a list of high-level categories with similar products. You can refine and restrict your search within a single category. You may need to browse several subcategories before you reach the most specific level. When you reach this point and have selected the best category for your product, you will continue on to enter and submit your product information to create a product detail page.
