Marine equipment must be UK-approved to be placed on board UK ships. This means it has valid UK conformity assessment certification and carries the Red Ensign - the UK conformity mark for marine equipment. Please see Part I of MSN 1874 as amended for further details.

Equipment covered under the UK-US Mutual Recognition Agreement for marine equipment, approved by the United States Coast Guard (USCG), accompanied by a US declaration of conformity, and affixed with the Red Ensign UK conformity mark is also acceptable. Please see Annex 6 of MSN 1874 as amended for details of what marine equipment categories are covered under the Agreement.
