Product classification
HS code for Clinical trial kits: 3006.93
Pharmaceutical goods, placebos and blinded (or double-blinded) clinical trial kits for a recognised clinical trial, put up in measured doses.
Classification of clinical trial kits under HS 3006.93
Clinical trial kits are classified under HS code 3006.93, a specific subheading within Chapter 30 which covers pharmaceutical products. This classification is determined by the unique nature of these goods as materials intended for use in recognized clinical trials. According to the General Rules of Interpretation (GRI), specifically Note 4 to Chapter 30, this heading includes placebos and blinded (or double-blinded) clinical trial kits that are put up in measured doses. The primary reason for this specific classification is to facilitate the international movement of research materials while ensuring they are not confused with commercial pharmaceutical products. These kits often contain a combination of active medicaments and inactive placebos, which are packaged together in a way that prevents the researcher or the patient from knowing which is which. To qualify for 3006.93, the kits must be intended for a trial that has been approved by the relevant health authorities in the country of use. The 'measured dose' requirement is critical; the items must be pre-portioned for individual administration, such as in blister packs or pre-filled syringes, rather than in bulk containers.

Codes often confused with 3006.93
Common mistake. Clinical trial kits are frequently misclassified under HS code 3004, which covers medicaments consisting of mixed or unmixed products for therapeutic or prophylactic uses. The confusion arises because the kits contain drugs; however, 3006.93 is a more specific heading for research materials. Another common error is using HS code 3822, which covers diagnostic or laboratory reagents. While trial kits are used in a laboratory or clinical setting, they are intended for administration to patients rather than for in vitro testing, which distinguishes them from reagents.
Top exporters and importers of HS 300693 (the code used for clinical trial kits), 2025
In 2025, the largest exporter of HS 300693 (the code used for clinical trial kits) in UN Comtrade data was the United States, with 37% of world exports; the largest importer in UN Comtrade data was Malaysia, with 38% of world imports.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
