3006.93 - Placebos and blinded (or double-blinded) clinical trial kits for a recognized clinical trial, put up in measured doses:

HTS Code 3006.93 specifically classifies placebos and blinded or double-blinded clinical trial kits when they are packaged in measured doses and intended for recognized clinical trials. These kits are distinct from other pharmaceutical preparations or medical devices and are distinguished by their role in research rather than direct therapeutic treatment. The primary purpose of these items is to serve as inert substances or otherwise indistinguishable formulations for comparison in controlled clinical studies.

This category is differentiated from its siblings, such as ostomy appliances (3006.91) and waste pharmaceuticals (3006.92), by its specific function in clinical trial protocols. While ostomy appliances are medical devices for waste management, and waste pharmaceuticals are expired or unusable medications, the kits under 3006.93 are active components of a research study designed to evaluate the efficacy and safety of actual medicinal preparations.

The subcategories within 3006.93 provide further refinement based on the composition and form of the placebo or clinical trial kit. These subdivisions include classifications for kits packaged with medicinal preparations (3006.93.10), those containing over 10 percent sugar by dry weight (3006.93.20), kits where starch or foodstuffs predominate (3006.93.50), liquid formulations for oral intake (3006.93.60), and placebos or kits containing chemicals other than medicaments (3006.93.80). These distinctions are crucial for accurate tariff classification based on the specific ingredients and presentation of the trial materials.
