Product classification
HS code for Denture cleaner: 3306.90
Oral or dental hygiene preparations, other than dentifrices.
Classification of denture cleaner under HS 3306.90
Denture cleaners are classified under HS code 3306.90. This classification is found within Chapter 33, which encompasses essential oils, resinoids, and perfumery, cosmetic, or toilet preparations. Heading 3306 is specifically dedicated to preparations for oral or dental hygiene. This includes products like dentifrices, yarn used to clean between the teeth (dental floss), and other preparations for oral hygiene. While 3306.10 is the specific code for dentifrices (toothpaste), 3306.90 serves as the "other" category for oral hygiene products that do not fit the definition of toothpaste. Denture cleaners, which are formulated to clean prosthetic teeth and remove bacterial biofilm, stains, and food particles, fall into this category. These products often contain oxidizing agents, chelating agents, and detergents specifically balanced for the materials used in dentures, such as acrylics and metals, distinguishing them from general household cleaners.

Codes often confused with 3306.90
Common mistake. Denture cleaners are often misclassified under HS code 3402, which covers organic surface-active agents and cleaning preparations. While denture cleaners do have cleaning properties, HS code 3306 is more specific to oral and dental hygiene, and according to the rules of specificity, the more specific heading takes precedence. Another error is using 3306.10, but this is reserved for toothpaste used on natural teeth.

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).
