Why does Amazon need the dimensions of a product?
Amazon needs dimensions for all products in its catalog to ensure it’s compliant with safety and hazmat regulations, ensure size for proper FBA warehouse routing and customer satisfaction.
If your item is getting kicked back because it is missing dimensions then that means Amazon doesn’t have them on file for that ASIN (or product). This is most likely due to that ASIN only ever being sold on the Amazon marketplace as Merchant Fulfilled or when the original listing was created the seller never entered the dimensions.
Remember, most of the stuff sold on Amazon is coming from 3rd parties and whoever creates the listing first is responsible for entering all the data about the product.
Amazon is just the marketplace for which these items sell on.
