We analyze the system Amazon deploys on the US “amazon.com” storefront to restrict shipments of certain products to specific regions. We found 17,050 products that Amazon restricted from being shipped to at least one world region. – While many of the shipping restrictions are related to regulations involving WiFi, car seats, and other heavily regulated product categories, the most common product category restricted by Amazon in our study was books.
