Preferential Origin

What is it
Some destinations require certification for certain commodities, to authenticate the country of origin of the merchandise/goods being shipped. Upon request, or when this documentation is missing at origin, DHL will attach it on behalf of the customer for a service charge. When exporting from the U.S., this service is available only for goods made in the United States.
