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. For files sizes above 10MB and less than 8GB you may submit correspondence via the ARL Secure Access File Exchange (SAFE) at https://safe.arl.army.mil/.
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.
