AUDIENCE: Emergency Medicine, Consumers



ISSUE: FDA has become aware of suspected counterfeit C-A-T® tourniquets which have subtle differences in stitching, printing of the logo and molding of plastic parts. Preliminary testing has shown that the suspected counterfeit tourniquet does not perform the same as the tourniquet manufactured by Composite Resources. The windlass is weaker in the suspected counterfeit product and breaks or bends before necessary force can be applied to stop blood flow. Excessive blood loss can endanger the victim’s life and ultimately lead to death.



BACKGROUND: The Combat Application Tourniquet (C-A-T®) consists of a strap that is placed around an injured limb (extremity) and then tightened with a tension rod (windlass) until blood flow stops. The windlass is secured in place so that the victim can be transported for emergency care. The tourniquet can be self-applied by the victim or it can be applied by another person.

One side of the tourniquet has, among other symbols, a C-A-T® logo with the outline of a cat and the National Supply Number NSN6515-01-521-7976. It is manufactured by Composite Resources and distributed by the following authorized distributors:





  • North American Rescue, LLC – Greer, SC
  • Cardinal Health – Mcgaw Park, IL
  • Owens and Minor – Mechanicsville, VA
  • American Purchasing Services – Opa Locka, FL
  • Phoenix Textile Corporation – O’Fallon, MO








  • Use only C-A-T® tourniquets manufactured by Composite Resources and purchased from one of the authorized distributors listed above. Others may be counterfeit and may fail in use.

  • If you have C-A-T® tourniquets you suspect may be counterfeit, replace them as soon as possible with the genuine devices. If a counterfeit fails, it can endanger a patient’s life.

  • Notify FDA’s Office of Criminal Investigations (OCI) if you suspect your tourniquet is counterfeit by contacting: Alex Alvarado, Special Agent, FDA Office of Criminal Investigations – (240) 276-9407.
