Our review of your firm’s website revealed statements that these breast binders (example trade names: “Birch Bareskin 2.0”, “Bone Bareskin 2.0”) are intended for use in the diagnosis of disease or other conditions, or in the cure, mitigation, treatment, or prevention of disease, or intended to affect the structure or any function of the body, including:

• Per your firm’s website: “Chest binding should never be harmful — yet we still see people getting injured from unsafe or poorly designed binders. We engineered our design to offer moderate compression, enough to help with gender dysphoria without cutting off your airflow or bruising your torso.”• Per your firm’s website: “Just about 5 years ago we were prepping to launch a Kickstarter campaign for our Bareskin Binder: a masculine swim top/binder option for folx who didn’t have the perfect dysphoria-easing solution”• Per your firm’s website: “Chest binding is the act of compressing breast tissue to create a flatter chest appearance. Many transmasc, nonbinary, and gender-nonconforming people bind as part of their gender expression or to ease gender dysphoria.”

Our review also revealed statements that you manufacture these devices within the meaning of section 510 of the Act (21 U.S.C. § 360) (e.g., “How we created a binder that disrupted the binder market forever.”). Under section 510 of the Act (21 U.S.C. § 360), manufacturers of medical devices are required to annually register with the FDA. In September 2007, section 510 of the Act was amended by the Food and Drug Administration Amendments Act of 2007 (Pub. L. 110-85) to require domestic and foreign device establishments to submit their annual establishment registration and device listing information to FDA by electronic means [section 510(p) of the Act (21 U.S.C. § 360(p))] during the period beginning October 1st and ending December 31st of each year. Our records indicate that you have not registered or listed these devices for fiscal year 2026.

Therefore the devices are misbranded within the meaning of section 502(o) of the Act (21 U.S.C. § 352(0)), in that they were manufactured, prepared, propagated, compounded, or processed in an establishment not duly registered under section 510 of the Act (21 U.S.C. § 360) and were not included in a list required by section 510(j) of the Act (21 U.S.C. § 360(j)).
