Browse node IDs are numeric codes that identify inside Amazon a given product category. You need to specify a node ID if you publish on Amazon a product not yet associated by Amazon to an ASIN.
If instead your product already has an ASIN, i.e. the internal Amazon’s Unique Product Identifier, the node ID you may assign to your Amazon listing becomes mostly irrelevant.
In Amazon’s own words:
Browse node IDs are positive integers that uniquely identify product sets, such as Literature & Fiction: (17), Medicine: (13996), Mystery & Thrillers: (18), Nonfiction: (53), Outdoors & Nature: (290060). Amazon uses thousands of browse node IDs..
While top-level browse node values tend to remain the same, the values of other browse nodes change often. Browse nodes are created and eliminated without notification.
Please note that node IDs are unique in one Amazon locale (e.g. Amazon.com, Amazon.co.uk, Amazon.fr, ...) The same node ID can be used in two or more Amazon locales, but the names and purposes of those nodes can be different and unrelated.
European vs. US node ID lookup
European and US + Canada sellers may find node IDs for their Amazon locale following these instructions:
Find the node ID’s for each category, using these tools provided by Amazon:
And so on for further locales. See screenshots below:

On Amazon.com, node ID’s have recently been moved and a little bit hidden for some reason. This is how to find them:
Use the product classifier tool for new products, available at this link to logged Amazon sellers: https://sellercentral.amazon.com/hz/productclassify
Browse the category tree to find your preferred category for the product or set of products you are about to publish. In the example below, we used: Beauty & Personal Care > Makeup > Eyes > Mascara.
Look in the URL for the “&recommendedBrowseNodeId=xxxxxx“. In our example, the code is “11058611“. This is the node ID you are looking for.
Now copy the code, paste it in Nembol Amazon “Publish to” settings and you are ready to rock!
