Country of Origin (COO) - Updating the information.
10-day restriction" associated with the Country of Origin.
I do not sell to EU and Uk.
This basically means that you need to insert a Country of Origin for each listing where it is unfilled.
This field is located at the last page of the listing editing interface.
I would rather fill it, even if you don’t sell internationally. But it can cause visibility issues, as your listings may become hidden.
From Amazon Seller Central:
“The Country of Origin (COO) of a product generally corresponds to the country where the product was produced or manufactured. If more than one country is involved in the product’s production or manufacturing, the COO generally corresponds to the country where the product underwent its last substantial transformation. However, more specific rules might apply depending on the relevant product type.”
