HTS heading 3407 is a broad product category for certain modeling and dental preparations. It includes modeling pastes, including products sold for children’s amusement; dental wax and dental impression compounds when presented in specified retail forms or shapes; and other dentistry preparations made with a basis of calcined gypsum or calcium sulfate.
The 4-digit heading is only the starting point. To choose the correct 8-digit HTS code, review the product’s composition, intended use, physical form, and packaging. The lower-level subheadings generally separate products by type—such as modeling paste, dental wax or impression material, or gypsum-based dental preparations—and may distinguish goods by their material or presentation. Confirm the current HTS wording and any relevant statistical suffix before entry.
What to check
- Identify the product’s principal use: general modeling, children’s amusement, dental waxing or impressions, or another dental application.
- Check the full ingredient or material composition, especially whether the preparation is based on calcined gypsum or calcium sulfate.
- Record the product’s physical form and retail presentation, such as a set, retail package, plate, horseshoe shape, stick, or similar form.
- Read the complete 8-digit subheading descriptions and compare them with the product’s technical data sheet, packaging, and marketing claims.
- If the composition or intended dental use is unclear, obtain a customs broker’s or classification specialist’s review before filing.

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.
