The defining characteristic of graduated compression hosiery is a measurable, calibrated pressure gradient — typically expressed in mmHg — engineered to improve venous circulation. Standard pantyhose and tights lack this engineered pressure profile and are classified here regardless of how snugly they fit. If a product is marketed with compression claims and has a documented pressure gradient, it should be evaluated under the compression hosiery heading instead.

Yes. The applicable HTS subheading — and therefore the duty rate — can vary based on whether the hosiery is made predominantly of synthetic fibers, cotton, wool, or other materials. Accurate fiber content testing and labeling are essential, as CBP may request laboratory analysis to verify the chief weight or chief value of the constituent fibers.
