The Coast Guard does not test materials or systems for approval but rather specifies the required test methods and minimum performance criteria for approval. Product testing must be performed by a Coast Guard Accepted or Recognized Independent Laboratory.
Please send the Submittal Package and other related information to TypeApproval@uscg.mil. Please see What to submit when corresponding with ENG-4 regarding equipment approvals/renewal. Submission of emails with file attachments above 10MB will not be received. For files over 10 MB, please contact us at firstname.lastname@example.org. We will send you a request to drop-off files at DoD SAFE (Secure Access File Exchange).
Once the equipment has been approved by this office, it will receive Coast Guard Type Approval and a Certificate of Approval (COA). The COA will be issued for 5 years and will remain valid during that time period if the product meets the testing of the Quality Control Program.
