If you're sending ShipHero Fulfillment goods from an international location, you will need to provide the freight company or supplier with your Business ID and/or US Tax ID. ShipHero Fulfillment is a 3rd party service provider and will not provide a Tax ID number to freight services.
The business entity (you, the shipper) is responsible for providing all Tax ID information to freight services. If there are questions regarding how to obtain this information, please contact your customs broker.
