HTS heading 6904 is a broad product category for certain ceramic construction products. It groups ceramic building bricks, flooring blocks, support or filler tiles, and similar articles used in building or structural applications. The heading describes the product’s general function and ceramic nature; it is not, by itself, the complete tariff classification.
To reach the correct 8-digit HTSUS code, start with the product’s physical characteristics and intended use, then follow the more specific subheading descriptions under heading 6904. The breakdown commonly distinguishes among product types—such as building bricks, flooring or paving blocks, and support or filler tiles—and may depend on details such as composition, shape, construction, or whether the article is specially designed for a particular use. Confirm the applicable code in the current official HTSUS and seek a customs broker or binding ruling when the facts are unclear.
What to check
- Identify the article’s exact construction use and whether it is a brick, flooring or paving block, support tile, filler tile, or another similar ceramic article.
- Verify the material and manufacturing details, including the type of ceramic, firing method if relevant, dimensions, shape, and whether the item is hollow, perforated, or otherwise configured.
- Read every subheading under heading 6904 and match the product to the narrowest description; do not choose a code based only on a marketing name.
- Compare the product description with the commercial invoice, technical data sheet, photographs, samples, and packaging information, and keep those records consistent.
- Check the current official HTSUS and consult a customs broker or request a binding classification ruling if multiple subheadings could apply.
HTS heading 6904 summary

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.
