When a government agency ships a package to an APO/FPO/DPO, SendSuite® Xpress 2.75 or Ascent™ 9.75 requires the use of customs forms even though the agency is exempt.
This change was caused by the SendSuite Xpress 2.75 or Ascent 9.75 update, which complied with United States Postal Service (USPS) requirement changes for overseas shipments. An exemption was not made for Official Mail customers.
