The US Arab Chamber of Commerce assists U.S. forwarders and exporters in legalizing Commercial Invoices and Certificates of Origin for use in Arab countries. Documents may be mailed to our USACC Legalization Office in Maryland or uploaded as a digital file on our website, provided they are signed and notarized by a local notary public. Documents will be processed on the same business day they are received. Start by clicking on the desired country name, and you will be directed on how to complete your request. Our new computerized system automatically emails customers when their packages are received and again when their completed documents are shipped back.
