结构推理 A certificate of origin must be issued by the party stated in the credit. However，if a credit requires a certificate of origin to be issued by the beneficiary，the exporter or the manufacturer，a document issued by a chamber of commerce will be deemed acceptable provided it clearly identifies the beneficiary，the exporter or the manufacturer as the case may be. If a credit does not state who is to issuethe certificate，then a document issued by any party，including the beneficiary，is acceptable.
