Quarantine Flags & Boat Flags for Sale | Fish Flags USA

At Fish Flags USA, we specialize in high-quality quarantine flags and boat flags that meet U.S. and international standards, ensuring you stay compliant, safe, and stylish on the water.

What is a Quarantine Flag?

A quarantine flag, also known as the Q flag or Yellow Jack, is a solid yellow flag that signifies a vessel is requesting “free pratique”—or clearance to enter a port after confirming there are no health concerns onboard. It’s typically flown when entering a foreign port before customs clearance.

Why You Need a Quality Quarantine Flag:

  • Required for international entry into many ports.
  • Communicates health status to port authorities.
