HS code for Mouthwash: 3306.90
Oral or dental hygiene preparations, other than dentifrices.
Classification of mouthwash under HS 3306.90
Mouthwash is classified under HS code 3306.90, which falls within Chapter 33 of the Harmonized System. This chapter covers essential oils and resinoids, as well as perfumery, cosmetic, or toilet preparations. Specifically, heading 3306 is dedicated to preparations for oral or dental hygiene. While 3306.10 is reserved for dentifrices (toothpaste), the subheading 3306.90 acts as a residual category for other oral hygiene products. Classification here is determined by the product's primary function as a cosmetic or preventative hygiene solution for the oral cavity. Even if the mouthwash contains antiseptic or antibacterial agents, it remains in this category provided it is intended for general hygiene rather than the treatment of a specific medical condition. The General Rules of Interpretation (GRI) 1 and 6 are applied to identify the specific heading and subheading based on the nomenclature of the Harmonized System.

Codes often confused with 3306.90
Common mistake. Mouthwash is frequently misclassified under HS code 3004.90, which covers medicaments consisting of mixed or unmixed products for therapeutic or prophylactic uses. This confusion arises when a mouthwash contains active medicinal ingredients. However, unless the product is specifically formulated and marketed as a treatment for a diagnosed pathology (such as severe gingivitis or oral thrush) and meets the criteria for Chapter 30, it remains in 3306.90. Another common error is using 3307.90, which covers other perfumery or cosmetic preparations, but 3306 is more specific to oral hygiene.

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).
