Is there a charge for filing an inquiry on International mail?
There is no charge for filing inquiries on International Mail, EXCEPT if the sender requests that an inquiry be transmitted by telegraph, cable, or facsimile, the request must be accompanied by an amount sufficient to pay the transmission charges. If a reply by telegraph, cable or facsimile is desired, the sender must pay the charges both ways. Such requests should be forwarded to the International Claims and Inquiries Office where the inquiry is being handled.
