Can I add product level shipping services with a product table import?
Yes. If your shipping services are similar for all products, this may be the quickest way to add them to a large catalog. A suggested approach- configure your product level shipping options for one product, export the product table, copy and paste the shipping information in the last columns of the spreadsheet (header names Irregular to InternationalShippingCountryCodes3) from the configured product to the rest of your products, then import the updated spreadsheet. You can update your catalog with product level shipping services using the product import process even if the store is currently configured with common shipping services for all products. The product level shipping options will not appear on the storefront or in store administration until the shipping configuration is changed.
