HTS heading 3506 is a broad product category for prepared glues and adhesives that are not more specifically covered elsewhere in the tariff. It also covers certain products that could be used as glue or adhesive when they are packaged for retail sale as glue or adhesive and have a net weight of no more than 1 kg. The heading can include products sold as liquids, pastes, powders, or other prepared forms, depending on their composition and presentation.
To reach the correct 8-digit HTS code, start with the applicable 6-digit subheading and then use the product’s distinguishing features. The tariff may separate products by material or chemical base, such as whether they are based on specific polymers, starches, or other substances, and may also distinguish retail adhesive products from other prepared adhesives. Review the full legal text, including section and chapter notes, because a product that appears adhesive-related may instead belong in another heading based on its composition, form, or intended use.
What to check
- Identify the adhesive’s actual chemical or material base from the manufacturer’s technical data sheet and, when available, the safety data sheet.
- Confirm whether the product is a prepared adhesive or merely a material that can be used to make an adhesive; do not assume all adhesive-related products belong in heading 3506.
- Check the packaging and net contents: the retail-sale provision has specific presentation and weight conditions, and net weight should be verified from product records.
- Read every competing 8-digit description and its legal notes, comparing the product’s composition, physical form, and intended use rather than relying only on a marketing name.
- Confirm the final classification with current official HTS text or a qualified customs broker when the formulation is mixed, proprietary, or potentially covered by another heading.

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.
