Title 33 › Chapter CHAPTER 33— - PREVENTION OF POLLUTION FROM SHIPS › § 1904

Last updated Apr 6, 2026|Official source

Summary

The Secretary must pick who can issue MARPOL certificates for the United States, except as provided in section 1903(b)(1). A ship registered in or of the nationality of a country that is not a MARPOL party cannot be issued a certificate. Certificates issued by other MARPOL party countries are as valid as those from the Secretary or the Administrator. Ships that must have a certificate must keep a valid one on board and may be inspected in U.S. ports or terminals. Inspections normally only check for a valid certificate unless there are clear reasons to suspect the ship or its equipment does not match the certificate. That does not stop other U.S. officials from boarding under other laws. In addition to penalties in section 1908, the law covers ships without a valid certificate or whose condition disagrees with the certificate. If a ship is detained, the Secretary may refuse or revoke its clearance under 46 U.S.C. 60105. Anyone whose ship is detained can ask the Secretary to review the detention under agency rules, and the Secretary must act within the time those rules set. A ship unreasonably detained or delayed by the Secretary is entitled to compensation for any loss or damage.
