Liberia Flag Seafarer Endorsements & CDC – Official Filing via TIRM UK

TIRM UK supports clients in processing Liberia flag seafarer endorsements and CDCs through Liberia's online application system, operated via registered filing agents. We help ensure your documentation is submitted correctly and promptly, whether you're applying for employment on Liberian-flagged vessels or as a non-Liberian seafarer.

​

Liberia Application Process & Turnaround

All endorsement and CDC applications are submitted electronically. The typical processing time ranges between 2–4 weeks, though a Certificate of Receipt of Application (CRA) can be issued at the time of submission upon request.

All application requests should be sent to crew@tirm.uk for review and processing.
