HTS heading 3306 is a broad product category for preparations used for oral or dental hygiene. It includes products such as dentifrices, mouth or oral-care preparations, denture fixative pastes and powders, and dental floss when presented in individual retail packages. The heading groups products by their primary use rather than treating every oral-care item as identical.
To reach the correct 8-digit HTSUS code, start with the product’s exact composition, function, and presentation. The subheadings generally separate products by type—such as dentifrice, denture-fixative preparation, or dental floss—and may then distinguish the material or form of the item. Review the full legal description, chapter and section notes, and any applicable statistical suffix; do not assume that all oral-care products belong in heading 3306 or that a brand name determines classification.
What to check
- Identify the product’s main function, physical form, ingredients or material, and packaging before comparing codes.
- Check whether the item is a preparation, a denture-fixative paste or powder, or dental floss in an individual retail package; packaging and intended sale form can affect classification.
- Read every level of the HTSUS description from heading through the 8-digit code, including notes and exclusions, rather than stopping at the 4-digit heading.
- Compare the product’s technical specifications, label, and marketing claims with the wording of the candidate subheading; obtain composition information from the manufacturer.
- Confirm the classification with current official HTSUS sources and, when the facts are uncertain or the stakes are significant, consult a licensed customs broker or request a binding ruling.

How to find your code in this category
A heading is a product category. To get the exact duty, narrow from this 4-digit heading to a sub-category (usually by material), then open the 8-digit code that matches your product.
Open any code in the tables below to see its exact duty rate, a duty calculator (enter your shipment value → estimated duty and landed cost), the rate-change history chart, and the country-by-country breakdown (including Section 301/232 add-on duties).
Why you have to click in: a single category can contain products with very different duties. The rate depends on the specific product — its material and construction — and on the country of origin, and those only get pinned down at the 8-digit code level. That is why this page points you to codes instead of showing one rate for the whole category.
