To send the Salesforce Products over to NetSuite, a Mass Update must be made to the products to fire the trigger that will sync the products to NetSuite. The Product Type must be set on each Product because the NetSuite CRM Connector will not send products without a Product Type.

You can use Data Loader to export fields, such as the Product Id & Name, then update using Data Loader and map the fields. This will fire the trigger for each product updated.
